When done correctly, AC installation can significantly lower energy costs. Reduced utility bills are among the best perks of replacing an air conditioner. However, ensuring your AC is energy-efficient requires planning, the correct installation procedures, and following your air conditioning contractor’s usage and maintenance recommendations. Here are 12 ways to ensure your energy costs decrease after AC installation.

• Hire a Qualified HVAC Contractor
• Buy the Right Sized Air Conditioner
• Prepare Your Home for AC Installation
• Check, Upgrade, or Replace Insulation
• Have Your Ductwork Tested and Sealed
• Choose the Best Location for the Condenser Unit
• Install a Smart Thermostat
• Consider a Zoned Air Conditioning System
• Choose an Eco-Friendly AC System
• Take Advantage of Energy-Efficient Settings
• Keep Sunlight Out of Your Home
• Schedule Annual Maintenance

1. Hire a Qualified HVAC Contractor

Finding a licensed, trained, and insured professional is the first step to having an energy-efficient AC. Before hiring a contractor, do your research. Check their credentials and experience in installing the type of system you need. Their reputation also matters, so look through online reviews and ask friends, neighbors, and family members if there’s an installer they’d recommend. Interview at least three contractors and compare each’s qualifications, professionalism, and pricing before selecting one.

2. Buy the Right Sized Air Conditioner

No AC is one size fits all. The size of the unit must match your home’s square footage. Other factors, such as ceiling height, the number of windows, and how many people occupy the space, are also important. An HVAC professional will perform an in-home evaluation and load calculation before finding suitable units. 

An incorrectly sized air conditioner can cause many problems. Too small a unit will run constantly and may not cool your home enough. An oversized AC may cycle on and off too frequently, which leaves little time to reduce humidity. It will also wear itself out and need more repairs. In any case, incorrect sizing will limit an AC unit’s efficiency.

3. Prepare Your Home for AC Installation

Preparing your home and the area where your AC will go makes it easier for the installation team and helps the unit perform at peak efficiency. The following tips can help you get the most out of your investment:

• Clear any furniture, objects, or debris from the installation area.
• Create a clear path from your entryway to the installation area. 
• Seal cracks, gaps, and drafts around windows, doors, and pipes.
• Make sure there’s enough clearance for AC components to be installed.
• Turn off electricity and gas to the area where technicians will work.

4. Check, Upgrade, or Replace Insulation

The insulation within walls and ceilings keeps cool air inside and prevents hot air from getting in. If the insulating materials in your home are old, poor, or deteriorated, energy efficiency won’t be optimal, no matter the quality of AC installation. Your HVAC contractor should check the insulation to determine if it should be replaced, updated, or added to. Common types of home insulation include foam boards, fiberglass batts, and blown-in cellulose.

5. Have Your Ductwork Tested and Sealed

Air conditioning contractors have professional-grade equipment to test ductwork for leaks. A leak from a crack, hole, or loose connection can cause conditioned air to escape. As a result, your new air conditioner will work harder to compensate for the lost air. Duct sealing optimizes efficiency and often doesn’t require demolition, depending on the method used. But if your ductwork needs major repairs and is several decades old, your AC contractor may suggest replacing it.

6. Choose the Best Location for the Condenser Unit

The condenser unit is among the most important parts of your AC system. Where you place it is also crucial. Installing an outdoor unit in direct sunlight can overheat it while placing it in a tight area interferes with ventilation. To maximize the entire system’s efficiency, install the outdoor unit:

• In a shaded area near a north- or south-facing wall. 
• With at least two feet of clearance on all sides.
• At least two feet from a nearby door or window.
• At least four feet away from a heat source.
• Where trees and shrubs won’t block airflow.

7. Install a Smart Thermostat

Integrating a smart thermostat during AC installation maximizes the unit’s efficiency from the start. You can set a cooling schedule and some models learn your habits automatically. Depending on the unit, you can monitor energy consumption and even control your air conditioner remotely. You can do so with your smartphone if you forget to turn it off before leaving. Or, you can lower the temperature so your home is cool when you arrive.

8. Consider a Zoned Air Conditioning System

Zoning lets you control the temperature in different rooms and areas independently. One zone can be set cooler depending on an occupant’s preferences. Aside from improving comfort, zoning increases energy efficiency by not cooling unused or underutilized spaces. A zoned system is also designed to eliminate the risks associated with closing vents in a traditional central AC system.

9. Choose an Eco-Friendly AC System

Eco-friendly cooling systems are usually on the efficient side. They include high-efficiency air conditioners and heat pumps that provide both heating and cooling. A heat pump is best suited for a warmer climate. Solar-powered units are also available. Aside from long-term energy savings, these systems reduce the release of greenhouse gases such as hydrofluorocarbons (HFCs).

10. Take Advantage of Energy-Efficient Settings

You can also lower energy costs after AC installation. For maximum comfort and efficiency, set the thermostat to 72℉ or 73℉. For each degree you increase the temperature, you can save 3% to 5% in energy while decreasing it further can increase energy consumption by as much as 10%. 

Most newer ACs have an “Eco Mode”, which slows down the compressor to save energy. Also, look for air conditioner units with a higher Energy Efficiency Ratio (EER). It is the ratio of cooling capacity to a system’s power output.

11. Keep Sunlight Out of Your Home

Close windows, shades, and blinds during the day to block sunlight. Otherwise, the sun’s rays can heat your home, forcing your air conditioner to work harder to compensate and keep things cool. Without the sun’s energy undoing the job it’s done, your AC can run more efficiently.

12. Schedule Annual Maintenance

Your local HVAC contractor’s maintenance plan includes services needed for your AC to run more efficiently. Routine inspections, cleanings, and adjustments can prevent breakdowns, costly repairs, and early AC replacement. They can also prevent or address issues such as an AC that smells, short cycles, or is making noise.

A technician keeps a unit in top shape by cleaning the coils, tightening electrical connections, measuring refrigerant levels, lubricating moving parts, and calibrating the thermostat, among other tasks. However, you don’t have to wait for a professional to visit your home. Changing the filter as recommended, keeping vents clean, and ensuring no part of the system is obstructed can protect it and lower energy costs.

It’s logical to consider ways to cut HVAC repair costs. According to Forbes, the average HVAC repair bill is $410 (in 2024 dollars). A service call, on average, costs $215. While a basic repair can set you back a few hundred dollars, a major air conditioning repair can exceed $2,500 or, in the case of replacing a compressor, rival the cost of installing a new system. 

Air conditioners are complex, hard-working appliances, so they will eventually need to be fixed. However, you can save money on repairs with the following tips:

1. Keep Your HVAC System Clean

Cleaning your HVAC system regularly reduces the cost and frequency of repairs. Dirt and debris can restrict airflow and contaminate the system, which can cause damage and accelerate wear. Therefore, you should perform these tasks on a routine basis:

• Replace or Clean the Air Filter: A dirty filter can seriously harm your HVAC system. Depending on the type, clean or replace it every two or three months. Install a new filter once a month if you use your AC or heater more frequently or your home is excessively dusty.
• Keep the Vents Clear: Dirt buildup can block vents and release debris into the air. Dusty or dirty vent covers should be removed and cleaned. You can clean them with a vacuum hose, a damp cloth, or by washing them in soap and water. Call an HVAC repair contractor to evaluate the system if this doesn't improve airflow.
• Clean the Outdoor Unit: Remove leaves, twigs, or debris that fall on the unit and clear debris or objects around it, leaving at least two feet of clearance. Also, trim plants and shrubs away. Anything that can block airflow can contribute to damage and more costly repairs. However, leave any tasks that require disassembling components and cleaning internal parts to a professional.

2. Wash the Condenser Coils

If the outdoor condenser coils are easily accessible, you can clean them yourself. These coils release heat the refrigerant has absorbed from inside your home. This process becomes inefficient if they become dirty, which can happen with exposure to the elements. Turn off the electricity to the system before rinsing the coils using a garden hose at low pressure. You can also look for cleaning products labeled safe for cleaning condenser coils.

3. Manage Your Thermostat Settings Wisely

The ideal temperature setting is 78℉, as the U.S. Department of Energy suggests, although many people prefer it a few degrees cooler in summer. Not setting the thermostat too low or too high reduces the demand on your HVAC system. Therefore, less strain can result in fewer costly repairs in the future. 

If you have a programmable thermostat, adjust it to accommodate your schedule. Setting it closer to the outdoor temperature when you’re away avoids overworking the system. You can also set it to adjust the temperature to a comfortable level before you return. A programmable unit can lessen the number of adjustments needed, saving energy and reducing strain.

Where a thermostat is installed can affect your HVAC system. It should be on an interior wall near your main living space, where it can most effectively monitor the temperature. A thermostat should not be in direct sunlight or near a vent or heat source. Otherwise, inaccurate readings can cause it to run your HVAC system more often, leading to more repairs.

4. Reduce Your AC’s Cooling Load

The less hard the system has to work, the more likely you can cut HVAC repair costs. Aside from how you install and set the thermostat, here are ways to ease the burden on your air conditioner:

• Close blinds to prevent heat from getting through windows.
• Set ceiling fans to rotate counterclockwise and direct cool air downward.
• Close the doors to rooms you don’t use.
• Turn your AC or heater off if you don’t need it.
• Run heat-producing appliances during cooler hours.
• Use kitchen/bathroom exhaust fans to reduce heat and humidity.

5. Don’t Procrastinate

Calling for help before the system breaks down can reduce HVAC repair costs significantly. Being proactive can save you a lot of money. Ignoring a small problem or waiving it off as no big deal can lead to more damage. Most issues start small, so call a skilled professional if the system:

• Isn’t heating or cooling your home as effectively
• Makes shrieking, buzzing, or hissing noises
• Cycles on and off too frequently
• Runs for longer than usual
• Releases musty or burning odors
• Leaks water or refrigerant

6. Consider a Duct Cleaning

Air ducts don’t require annual maintenance, but should be cleaned once every three to five years. Even a thin layer of dust and debris can restrict airflow. Dust mites, bugs, and bacteria may be present while mold can cause serious damage to your HVAC system. It can also circulate spores and toxins throughout your home.

A trained HVAC technician knows how to inspect and safely clean your duct system. They can use negative pressure, HEPA vacuums, and brushes to clear our main and branch ducts, plenums, and other components. These methods prevent or eliminate reduced airflow and high pressure that can damage your AC, heater, and air ducts.

7. Seal Any Air Leaks

Air leakage from ductwork and elsewhere in your home can let cooled or heated air escape and unconditioned air in. Therefore, your HVAC system works harder to maintain a comfortable temperature. Your local HVAC contractor can look for cracks, holes, and loose connections in ductwork and use the latest methods to seal them. Gaps around doors and windows can also cause air leakage but are easily sealed with caulking or weatherstripping.

8. Avoid DIY Repairs

Other than simple tasks like changing filters, cleaning coils you can access, or sealing small air leaks, leave HVAC repairs to a professional. Attempting a DIY repair can have costly consequences. It can also be dangerous and cause an injury. 

Using the wrong tool, misdiagnosing the issue, or making one mistake can result in damage that requires more expensive repairs. You may also void the manufacturer’s warranty by tampering with the system. Therefore, you would have to pay the full cost of any repair or replacement due to any error.

9. Get Multiple Quotes

When you need an HVAC repair, contacting multiple companies for a quote can help cut repair costs. Search online or ask relatives or neighbors about companies they’ve worked with and narrow your choices down to three or four providers. Read online reviews and ratings to verify they’re qualified for the job and are reliable. Then, each contractor should evaluate the issue separately and compare prices by considering the services including materials used, and the type of support, warranty, etc., the company provides. 

10. Consider Replacing Your HVAC System

Deciding whether to repair or replace your AC unit can help achieve long-term savings. If your air conditioner is 15 to 20 years old, frequent repairs and reduced efficiency may cost you more than replacing it. Having a new system installed avoids major repairs and can lower your energy bills, not to mention improve comfort and indoor air quality.

11. Schedule Annual AC Maintenance

If you don’t keep up with annual maintenance (one tune-up for your AC in the spring and one for your furnace in the fall), higher HVAC repair costs are almost certain. A maintenance technician is trained to spot and correct any issues early. Addressing minor problems, cleaning your AC system, and making adjustments can eliminate the strain that causes larger components to fail. 

During a maintenance call, a contractor should lubricate moving parts to reduce friction. They should also measure and recharge refrigerant levels to avoid performance issues and check electrical components for shorts, wear, and corrosion that can lead to more serious damage.

Avoiding a large and costly air conditioning repair is easier than you might think. Good habits and some simple tasks can reduce wear on expensive parts. They can also avoid breaking out in a sweat indoors during the warmest days of the year. Aside from maintaining your comfort, the following steps can prevent costly AC breakdowns, emergency calls, and early system replacement:

• Hire a Qualified Professional for AC Installation
• Change the AC Filter as Recommended
• Lessen the Demand on Your Air Conditioner
• Open All Vents and Keep Them Clear
• Keep an Eye on the Thermostat
• Make Sure the Outdoor Unit Is Clean
• Check for a Clogged Condensate Drain
• Call for Help If the Evaporator Coil Freezes
• Don’t Ignore Signs of a Refrigerant Leak
• Schedule an Annual AC Tune-Up

1. Hire a Qualified Professional for AC Installation

Avoiding future repairs starts before you turn your AC on for the first time. A licensed contractor matches the right air conditioner with your home, considering factors such as unit type, efficiency rating, and size. An AC’s size refers to its capacity. If the unit is too large for a space, it will cycle on and off too frequently, while too small a unit will run too long. Either way, you’ll see poor cooling performance, higher energy bills, and possibly increased repair costs.

Hiring a professional also ensures the system is properly installed and connected. The refrigerant, drain, and electrical connections must be secure for it to run smoothly, efficiently, and safely. The upfront cost is worth it considering what you may pay in air conditioning repairs otherwise, especially since most warranties won’t cover a system unless a licensed contractor installs it.

2. Change the AC Filter as Recommended

Most HVAC professionals recommend changing the air filter at least every three months. However, depending on the filter, how dusty your home is, and if you have pets, it may need to be changed as often as every 30 days. Following these guidelines can avoid major repairs. The filter protects your AC system from dirt and debris that can damage sensitive components. 

A clogged filter also blocks airflow. Your AC system will then work harder and less efficiently, which can make your home uncomfortable and lead to expensive repairs. Changing the filter takes just a few minutes. Therefore, save time and money by following the manufacturer’s recommendations. This can extend the life of your air conditioner significantly.

3. Lessen the Demand on Your Air Conditioner

The more you use your AC, the greater the rate of wear and tear. However, you can reduce the demand on the system in a few simple ways. You can possibly avoid a major air conditioning repair by taking these steps:

• Turn up the thermostat a couple of degrees, but still at a comfortable temperature.
• Install a programmable thermostat so you can schedule when your AC turns on and off.
• Use a ceiling fan to make it feel a few degrees cooler.
• Turn the air conditioner off when you’re not at home.
• Close blinds and curtains to keep out heat from sunlight.

4. Open All Vents and Keep Them Clear

If you’re not using a room, closing an AC vent won’t reduce energy consumption. Keep all the vents open to avoid efficiency and air pressure issues that can strain the system. Also, move furniture, storage units, blinds, drapes, or other items that block any vents. Just by keeping all the vents open and clear, you can avoid the surprise expense of a major air conditioning repair.

5. Keep an Eye on the Thermostat

Although it’s relatively small, the thermostat is among the most important parts of your HVAC system. It is the control center for your AC, heating unit, and system fans. Therefore, a thermostat problem can cause the system to run when not necessary, not turn on when you need it, or turn on and off too frequently. 

Any changes in system performance can point to a malfunctioning thermostat. Check the unit’s accuracy; the temperature reading should match the set temperature when the system is running. Mechanical problems and wiring damage can affect temperature/humidity control and increase the risk of shocks, fires, and other hazards. Call for help as soon as you notice any changes in how your thermostat is working.

6. Make Sure the Outdoor Unit Is Clean

The outdoor condenser unit contains vital components that maintain airflow and release heat. If it becomes dirty, your entire AC system can malfunction. To prevent issues that can lead to a major air conditioner repair:

• Clear leaves, branches, and twigs from the top of the unit.
• Maintain at least two feet of clearance on all sides.
• Keep the unit shaded so direct sunlight doesn’t overheat and strain it.

Also, check the outdoor unit’s coils and fins for dirt and debris. Cleaning the unit can prevent various problems. To do so, turn off the power, remove the fan assembly, and use a soft brush or vacuum to clean the coils and fins. Follow the manufacturer’s instructions for cleaning your specific type of unit; or, to be on the safe side, call a professional. 

7. Check for a Clogged Condensate Drain

The condensate drain line removes water that condenses from moisture your AC system collects from the air. If the line becomes clogged, indoor humidity levels can increase, while the problem can also lead to water damage and mold (resulting in serious damage to your HVAC system and home). Check the condensate drain often for blockages. There are home remedies for unclogging it, but hiring a professional can save money and avoid a major air conditioning repair.

8. Call for Help If the Evaporator Coil Freezes

A frozen evaporator coil can do a lot of damage and is often a sign of other problems. Turn off your AC right away. Leaving it off or running the fan for a while may thaw out the coil. However, the best option is to call a repair technician to defrost it and determine what caused the problem. The reasons can range from a clogged filter to a refrigerant leak. Ignoring the issue may lead to damage that requires replacing the coil or the most expensive AC repair—compressor replacement.

9. Don’t Ignore Signs of a Refrigerant Leak

A refrigerant leak can cause your AC system to overheat and break down. Over time, wear and tear and corrosion can affect the coils. The refrigerant is contained in a closed system and doesn’t get used up. Therefore, if you have to recharge the system, there’s most likely a leak somewhere. Call a professional for the following signs of a refrigerant leak:

• Reduced cooling performance
• The AC isn’t dehumidifying the air
• Cooling cycles are running longer
• The evaporator coils are icy
• Hissing or bubbling sounds from the outdoor unit
• Inefficiencies are driving up your energy bills

10. Schedule an Annual AC Tune-Up

As much as you want to avoid calling a local AC contractor, doing so annually can prevent costly air conditioning repairs. A technician has the tools and expertise to properly clean sensitive components, measure refrigerant levels, and lubricate moving parts. They can also check for damage to electrical parts and look for duct leaks. Taking corrective measures for smaller issues can avoid larger repairs and save much money over the life of the system.

Air scrubbers improve indoor air quality in many ways. They remove tiny particles and other pollutants you can’t see but can impact your health and HVAC system. An air scrubber is far more efficient than a standard media filter in your air handler unit. We’ll look at what it is, how it works, and the benefits this advanced air filtration system can provide. 

The information below can help you decide if it’s time to contact one of Trio’s air scrubber installers, who can find the best air-cleaning solution for your home.

How Does an Air Scrubber Work?

An air scrubber is a sophisticated device installed in your HVAC ductwork. It purifies the air circulating in your home by a series of filter elements. Depending on the model, it may include more than high-efficiency particulate filters. Some units incorporate ultraviolet (UV) light and catalytic processes that neutralize organic and other pollutants.

The standard parts of an air scrubber include:

• Pre-Filter: It removes larger particles. Although not visible to the naked eye, these can irritate and clog parts of your HVAC system. The pre-filter protects other filters from clogging and can increase their lifespan. It also helps maintain the airflow rate.
• Primary Filter: Particles smaller than one micrometer are removed by this HEPA filter at the second stage of the system. It increases the air scrubber’s efficiency.
• Carbon Filter: Although not a standard air scrubber component, a carbon filter can be added to remove toxic chemicals and materials. It improves an air scrubber’s ability to remove odor-causing gases and vapors.
• UV Light: Ultraviolet light breaks down the DNA of organic contaminants, rendering them inert and unable to reproduce and causing infections and illnesses.
• Blower Mechanism: This mechanism enables the air scrubber to pull air into the filtration system. Often referred to as the fan, it may have variable speed capabilities to accommodate the air stream’s rate and pressure.

Exactly how an air scrubber improves indoor air quality depends on the type. The most common forms of this technology include:

• Dry Air Scrubbers: Many dry air scrubbers feature a filter stack that integrates a high-efficiency particulate air (HEPA) filter, which can remove bacteria and many viruses.
• Wet Air Scrubbers: Most often installed in manufacturing facilities, these use a mist that adheres to dust and other particles. The most advanced systems include mist eliminators, fans, pumps, and collection vessels.
• Integrated Air Scrubbers: While some basic air scrubbers are portable, an integrated system is built into your HVAC system. It comes in many sizes, including units sized appropriately for your home.
• Electrostatic Precipitator: It uses an electric charge to bind and capture material, which ranges from dust to particulates from gases. Depending on the type, particles may attach to a grounded plate, collecting surface, or collection container.
• Negative Air Scrubber: By creating negative air pressure, it captures and collects contaminants and prevents them from leaving a specific area, especially during a renovation. Negative air scrubbers also contain multi-stage HEPA filtration.

Ways In Which an Air Scrubber Improves Indoor Air Quality

An air scrubber can improve the air quality in your home on many levels. It operates continuously as air is circulated and recirculated. These are a few ways it can achieve cleaner, healthier indoor air:

Remove Circulating Debris

An air scrubber effectively removes dust, pollen, mold spores, and volatile organic compounds (VOCs). Therefore, it removes particulates that contribute to allergy symptoms and asthma attacks. It also removes chemicals released by everyday household cleaners, some furniture, carpets, draperies, and composite wood products. If your home is dusty no matter how often you clean it and people in your household often experience sneezing, coughing, and congestion, contact an air scrubber installer to find the best solution. 

Eliminate Airborne Germs

An air scrubber, especially one with a HEPA filter and UV light, can trap bacteria and even eliminate pathogens such as flu viruses and COVID-19. Its ability to prevent airborne germs from spreading makes an air scrubber one of the best solutions for improving indoor air quality and sanitizing your home. The system doesn’t only remove particles from the air. It also removes particulate matter from surfaces such as countertops and door knobs where contact with germs is most common. To do so, it emits oxidizers or ions into the air that disperse and neutralize these pathogens.

Eliminate Odors

Odors can be caused by circulating dust particles, smoke, paint fumes, and chemicals from various sources around your home. They can linger for hours after cooking. The pets you love can also contribute to household odors. While some odors are inconvenient, others can be emitted by hazardous substances. Air scrubbers remove all kinds of odors. Therefore, your home not only smells better but its overall indoor air quality is improved.

Improve HVAC Performance/Efficiency

Airborne particles and debris can contaminate your HVAC system. The effects can range from air filters that clog more quickly to damaged blowers, coils, and other components. Such damage can lead to expensive repairs and early system replacements. A decline in heating or cooling system performance can also lead to indoor air quality issues, including uneven temperatures, increased humidity, and dust and debris from dirty ductwork. An air scrubber can improve HVAC efficiency and extend the system’s operating life.

FAQs

How Does an Air Scrubber Differ from an Air Purifier?

An air purifier only removes airborne contaminants. In addition to removing airborne particles, an air scrubber can clean surfaces. It also doesn’t release ozone as some ionizing air purifiers can. Ozone can be harmful to human health and does not remove dust and other particles that cause allergies.

Do I Need an Air Scrubber?

An air scrubber can provide fresher air, contribute to better sleep, and improve your overall quality of life. It is worth considering if:

• You or someone in your family have frequent allergy symptoms, especially while at home.
• People in your household get sick often or have underlying issues that make them more vulnerable.
• Dust, pet dander, mold, and other compounds are common in your home.
• Your home has persistent odors from cooking, pets, smoking, and other sources.
• You’re concerned about potentially harmful contaminants in bathroom, kitchen, and other surfaces.

Should I Hire an Air Scrubber Installer?

An HVAC professional can help find the best model for your HVAC system and home. They can also perform an indoor air quality assessment, which is beneficial because there are many types of air scrubbers and laws regulating legal thresholds for certain pollutants. Also, the installation process may require some modifications to your ductwork, which can require a permit not to mention complex work that should be left to a professional.

A few attic and crawl space insulation options are available. Poor insulation can reduce your comfort and cause you to spend more on heating and cooling. But the best type depends on your home. We’ll look at the most common types of attic insulation and insulating materials best suited for crawl spaces so you can make an informed decision.

Common Home Insulation Materials

Insulation prevents drafts and the transfer of heat and moisture. Since heat naturally rises, the attic is one of the most important areas to insulate. Each type of insulation has pros and cons and is not suited for every situation. These are the top choices, although the best depends on your needs, budget, and local climate.

Spray Foam Insulation

Spray foam is the only liquid-based insulation. It has many benefits, including ease of application. The material is sprayed into place, where it thickens and grows, filling any gaps or spaces where heat can escape. It forms a durable, airtight seal.

An insulation’s R-value measures its ability to resist the movement of heat (the higher the number, the better a material’s thermal performance). Spray foam has an R-value of 5.6 to 8, which makes it an effective insulator. Other benefits of using it include:

• Spray foam maintains its quality over time
• The foam provides some structural support
• No vapor barrier, so the foam won’t trap moisture
• A Class-1 Fire Rating
• Resistance to mold and mildew growth
• Doesn’t provide a food source for pests

The higher cost of spray foam insulation is offset by its energy efficiency. Precautions are recommended during installation; a mask, respirator, and goggles should be worn. The materials in the foam can irritate your skin. We suggest letting a professional install spray foam insulation, as they understand the complexities involved.

Foam Board Insulation

Rigid foam boards are great for insulating basements and are preferred for crawl space insulation. They are suited for insulating foundation walls. Sealing the joints between the boards prevents air passage, while rigid foam:

• Is non-water absorbent
• Doesn’t support mold growth 
• Provides a high level of energy efficiency

Available in standard sizes, foam boards are easy to cut to fit. This usually requires a circular saw and masonry blade, but sometimes a utility knife can be used to score the material; then you can snap it apart. It’s also easily attached with screws or a special adhesive. Smaller pieces can be sealed with caulk or spray foam.

The types of foam board insulation include:

• Expanded polystyrene (EPS): EPS is the cheapest form and the same material as disposable coffee cups. However, it only has an R-value of 4 per inch of thickness.
• Extruded Polystyrene: A denser material available in pink or blue panels, it has an R-value of 5 per inch of thickness. Panels with tongue-and-groove edges limit air movement.
• Polyiso (Polyisocyanurate): This more costly material provides an R-value of 6 per inch of thickness. Various thicknesses are available, and the material is often foil-faced to reflect heat.

Fiberglass Batt Insulation

The most common type of attic insulation, fiberglass batts have a recognizable pink cotton candy or cloud appearance. They consist of tiny glass fibers produced via heat from recycled material and sand. The fibers are rolled into large sheets fused by a chemical vapor.

The benefits of fiberglass batt insulation, and why it’s such a popular option, include:

• Production from a renewable energy source (sand).
• A flame-proof vapor barrier can slow the spread of fires.
• Air pockets prevent the material from shrinking or collapsing.
• It is soundproof, reducing internal and external noises.
• DIY installation is possible.

While many people don’t need a professional to install fiberglass batt insulation, it doesn’t come without risks. The glass in the material can cause injury, while the vapor from the barrier can be harmful (wearing gloves and a mask protects you from harm). 

Other downsides to this insulation include reduced performance if it gets wet. Fiberglass batts take a long time to dry and can breed mold after absorbing moisture. The insulation is also attractive to rodents and other pests.

Blown-In Fiberglass Insulation

Blown-in fiberglass insulation is also available. The base material is the same as with batts (without the vapor). It is installed using a blowing machine. In addition, blown-in fiberglass insulation provides an airtight layer, filling cracks or gaps to limit the movement of hot or cold air. It also has sound-insulating properties.

Other perks include:

• Faster Installation: The blown-in method is quicker than installing fiberglass batts. Rather than days, it takes just hours. 
• Improved Air Quality: The absence of a vapor improves indoor air quality, which is beneficial for people with allergies.
• Proper Care Maintains Efficiency: With routine maintenance, you can prevent the R-value from decreasing due to settling.

Blown-In Cellulose Insulation

This attic insulation is also applied using a blowing machine. It consists of recycled wood, cardboard, newspapers, and other materials, which are made flameproof with boric acid and other substances. Blowing the material in fills spaces and gaps in attic walls. 

Blown-in cellulose is eco-friendly; no new material needs to be produced and it can be reused. It also has a 23% higher R-value than fiberglass batts. Wind-washing is reduced as well. This phenomenon is when insulation is pushed away from the edges, which reduces thermal performance.

These advantages help offset cons such as messy installation. The cellulose should also be kept dry. Any dampness can allow mold to grow. Such a situation takes much time and effort to resolve, as the insulation must be cleaned up bit by bit.

How Do I Choose the Right Insulation?

The best insulation to choose depends on where you’re installing it. Foam boards are best for crawl spaces. Also, think about how you’re using the space. Consider properties such as the type of material, its thickness, insulating value, sound absorption, energy efficiency, and ability to control moisture. However, if you intend to turn your attic into a living space, you may want to insulate the roof instead. 

How Do I Find the Best R-value for Insulation?

The level of heat resistance you need depends on your home’s location and climate. The U.S. Environmental Protection Agency (EPA) has established eight climate zones across the country. The recommendations for insulation efficiency in an attic, floor, etc. vary depending on the zone you live in. Generally, the farther north you live, the colder your location, and the higher in altitude you are, the higher the R-value you’ll need.

How Do I Know My Home Needs More Insulation?

Signs your home is under-insulated include a sudden increase in energy bills, meaning your HVAC system is working harder. Cold spots, especially near windows and doors, can mean air is leaking through cracks or seams. Hearing lots of noise from outside can mean your walls and ceilings need to be better insulated.

Everyone benefits from cleaner air, but it can come at a price. The cost of a whole house purification system can range from $400 to $4,000 (in 2024 dollars), according to HomeGuide. However, the exact amount you spend on installation depends on the following:

• Type of System/Filter
• Brand of Equipment
• Efficiency Rating
• Size of Your Home
• Labor and Other Installation Costs

In this guide, we’ll look at all these factors. It can help you budget for a whole house purification system that meets your household’s indoor air quality needs.

Air Purification System Cost Variables

The cost of central air purifiers varies considerably. The national average is $1,300, but you can spend just a few hundred dollars on a low-end system.¹ Meanwhile, a high-end system can cost several thousand dollars. Why is there such a difference? To answer this question and help you understand how whole house purification systems are priced, here are the factors to consider:

Type of System

A purification system is generally defined by the type of filter it includes. The cheapest type is a single-function system, while multi-stage systems that remove the smallest particles are the costliest. Here are the average costs of the most common whole-house air purification systems:

• Flat Filter ($10 to $70): A flat filter traps more particles than a standard HVAC filter and removes dust, pet dander, and mold spores. However, it’s the least effective whole-house filter type and must be replaced every 1 to 3 months.¹
• Electronic Filter ($300 to $1,000): An electronic filter attracts and traps airborne particles via an electrical field. An electrostatic precipitator uses an electrostatically charged metal plate. More effective at capturing smaller particulates, the filter plate must be cleaned every 3 to 6 months.¹
• Extended Media Filter ($100 to $300): This features a thick pleated material that captures particles. The filter box is installed in your existing ductwork. However, adding one requires installing a media filter cabinet, which may require retrofitting your HVAC system.¹
• High-Efficiency Particulate Air (HEPA) Filter ($600 to $3,000): A HEPA filter pushes air through a thick mesh to trap dust, pollen, and smoke. It can also capture bacteria and many viruses. Able to trap 99.97% of airborne particulates, some high-density HEPA filters can restrict airflow, so consult with a professional before installing one.¹
• Ultraviolet (UV) Light Filter ($200 to $400): A UV filter emits ultraviolet light to neutralize germs and mold circulating in the air. Maintaining the system is affordable; replacing the UV bulbs costs less than $70 annually. However, a UV filter does not remove dust, allergens, or smoke (hybrid systems include mechanical filtration for this, but the equipment can cost up to $1,800).¹ 
• Portable Filters ($500 to $1,800): If you don’t have a ducted HVAC system, you can install a portable home air filtration system. It does not require professional installation, but annual filter media replacement costs $40 to $100.¹

Brand

Many companies make whole-house air purifiers. Prices vary significantly from one brand to another. For example, brands such as Field Controls, Honeywell, and Reme Halo tend to cost less than higher-end names like Carrier, Trane, and Lennox. 

Each brand may offer various options at different price points. Shopping around can help you find an affordable solution. Look for products with Energy Star certification. Efficiency is important as the system must run constantly to achieve and maintain good indoor air quality. 

Also, try to find equipment covered by a long-term warranty. This requires installation by a licensed contractor but can result in savings on service over the system’s life.

Efficiency

Higher-efficiency filtration systems cost more. However, you must weigh the benefits of having one, such as relief from allergies and respiratory issues. If your pets shed a lot, a high-efficiency whole house purification system can remove excess hair and dander.

Whole-house HVAC filters are rated using a Minimum Efficiency Reporting Value (MERV). The most common ratings for air filters include:

• MERV 1-4: The most basic type of filter that captures pollen, dust mites, and carpet fibers. It captures less than 20% of particles 3 to 10 microns in size.¹
• MERV 5-8: Suited for most homes, this filter blocks most common pollutants and 50% to 85% of particles 3 to 10 microns in size.¹
• MERV 9-12: Able to remove 85% to 90% of 3- to 10-micron size particles and up to 89% of 1- to 3-micron size particles, it can capture pet dander, mold spores, and fine dust.¹
• MERV 13-16: It can capture over 90% of 1- to 10-micron particles and 75% to 95% of 0.3- to 1-micron particles, meaning it can filter smoke, fumes, bacteria, and viruses.¹

Home Size

The larger a home, the more powerful an air purification system it will need. A large house may also require multiple filtration units, as can one with multiple levels or an open floor plan. An installer must consider your home’s size, layout, and other features before determining the ideal type of system. The larger and more complex it is, the more it’ll cost to purchase and install.

Labor and Other Costs

Labor charges can add significantly to the cost of a whole-house purification system. With labor included, a whole-house HEPA system can cost $4,000. An extended media air filter or UV filtration system can cost up to $800 (installing a hybrid UV/mechanical filtration system can cost up to $3,000). Combining equipment and installation costs, an electronic filter can cost as much as $2,000.¹

However, the total cost of installing a whole house purification system is determined by more than the price of equipment and labor. These are some other variables to consider:

• Accessibility: If your HVAC equipment is in an attic, crawlspace, or other hard-to-access location, installing a whole house purification system will cost more.
• HVAC Inspection: An inspection can identify any AC, heater, or ductwork problems before the filter system is installed, but costs $150 to $500.¹
• Ductwork Replacement: Installing an air purification system may require ductwork replacement (which can cost up to $500 per duct run) or duct cleaning, which averages $300 to $700.¹
• Outlet Installation: Installing a new electrical outlet to power the air purification system can cost $150 to $350.¹
