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

You can avoid or delay thermostat repair with proper maintenance. A well-maintained thermostat generally lasts about 10 years. Although one of the least expensive HVAC components to replace, it’s crucial for reaching and sustaining optimal temperatures in your home. 

A thermostat is wired directly to your heating and cooling system. It allows for the temperature to be adjusted and the system to be turned on and off manually or automatically. Therefore, thermostat maintenance should be part of your routine. These are some tips to keep it in top shape:

Replace the Batteries

Clean the Thermostat Often

Adjust the Anticipator

Avoid Changing Settings Too Frequently

Be Mindful of Thermostat Placement

Set a Heating or Cooling Schedule

Calibrate the Thermostat

Take Error Codes Seriously

Take Advantage of All the System’s Features

Schedule Professional Maintenance Every Year

1. Replace the Batteries

A low battery reduces the amount of power available to your thermostat. This can make it inaccurate and less able to manage your comfort. To avoid these issues, replace the thermostat batteries every six months or as the manufacturer recommends. Even if your thermostat is hardwired, it may have backup batteries. Change these to prevent disruptions in heating and cooling due to a wiring issue.

2. Clean the Thermostat Often

A buildup of dirt and dust can prevent your thermostat from working properly. Cleaning it every few months can avoid HVAC performance issues due to controller malfunctions. To clean a thermostat:

• Snap off or unscrew the cover, depending on the model.
• Using a soft brush, dust off internal components.
• Use compressed air to clear debris from tight spaces.
• Look for loose or corroded wires; call an electrician to fix any issues.
• Clean the cover and place it back on the unit.

3. Adjust the Anticipator

If you have an older thermostat, it may have a heat anticipator. It saves energy by turning off a furnace or boiler early and allowing residual heat to maintain the room temperature. Adjusting the anticipator can restore normal cycling. This requires moving the pointer toward a higher setting if the system is cycling too frequently or a lower setting if it’s not turning on enough.

4. Avoid Changing Settings Too Frequently

Adjusting the setting too often causes your HVAC system to work harder, increasing energy consumption. This is true no matter what type of thermostat you have. However, frequent adjustments are even harder on mechanical units. It’s best to find an optimal setting so you’re not constantly adjusting the temperature or forgetting to readjust it when you leave home or go to sleep. Or, consider upgrading to a programmable or smart thermostat. 

5. Be Mindful of Thermostat Placement

Constant exposure to high heat can damage a thermostat. The unit should not be near a heat source, such as direct sunlight, a draft, or an appliance. To protect its integrity and accuracy, it should be mounted on an interior wall in or near a frequently used room.

Excess heat can cause inaccurate readings, affect the cycling and efficiency of your HVAC system, and increase the likelihood you’ll need thermostat repair. Consider relocating your thermostat. Or, address the problem by closing a window shade, sealing a draft, or moving heat-producing appliances (if possible). 

6. Set a Heating or Cooling Schedule

Setting a schedule can save energy, provide more consistent comfort, and avoid having to adjust the temperature throughout the day. Programmable thermostats can be set on daily or weekly schedules based on when you’re home or away. Avoid using the “Hold” feature indefinitely because it can overwork your HVAC system.

Depending on the model, smart thermostats can learn and adapt to your behavior, while geofencing allows some units to sense when you’re arriving home and adjust the temperature accordingly. Other models integrate with other smart devices so, for example, they can lower the temperature once a smart door lock is triggered.

7. Calibrate the Thermostat

If the temperature keeps fluctuating, your energy bills are increasing, or your HVAC system is running more frequently, your thermostat may need calibration. To calibrate a thermostat, compare its reading with a dependable thermometer. If the readings differ by more than 3℉ after 20 minutes, check the product manual for how to calibrate the unit. Calibration techniques differ based on the type and model of a thermostat. 

8. Take Error Codes Seriously

If your thermostat detects a problem, it may display an error code. The user manual should list each code and what it means. Common error codes indicate:

• A malfunctioning thermostat
• A faulty temperature sensor
• The unit needs calibration
• An HVAC system error
• The filter must be replaced
• The system is overdue for maintenance
• Wi-Fi has been disconnected
• The thermostat’s batteries are low
• A faulty wiring connection
• A firmware update has failed
• An HVAC unit is overheating
• The temperature is outside the normal range

Ignoring an alert can lead to missed maintenance, which increases wear and tear. It can also lead to reduced efficiency, costly repairs, and a decreased system lifespan.

9. Take Advantage of All the System’s Features

Newer thermostats have advanced features that improve functionality and can avoid the need for thermostat repair. Some of these include:

• Eco Mode: Some programmable and smart thermostats have an Eco Mode that saves energy, reduces your carbon footprint, and can improve comfort. It also provides the convenience of automation.
• Zoning: If your thermostat is compatible with a zoning system, you can achieve the desired comfort level in each room. Zoning also helps reduce wear and tear because heating, cooling, and airflow are directed to where it’s needed.
• Energy Reports: Analyzing energy reports from a smart thermostat can help you identify usage patterns and opportunities to save energy. It can also help determine whether to schedule service, which can avoid major repairs and increase your HVAC system’s longevity.

10. Schedule Professional Maintenance Every Year

A thermostat, with the rest of your HVAC system, should be evaluated at least once a year. Your local HVAC contractor can test and calibrate the thermostat for you. They can also check the unit for issues to fix before they lead to more expensive AC, heater, or thermostat repairs.

At Trio Heating & Air, we’re proudly upgrading our service vehicles to a Tesla fleet. This signifies the principle behind our new slogan: “Trio: Where Sustainability Meets Service Excellence”. Aside from planting a tree for every job we do (which means a great deal for the region), we’re committed to environmental sustainability and high-quality service in every aspect of our work, down to the vehicles our employees drive.

Until now, we have relied on gas-powered vans. Investing in Teslas is allowing us to convert to an eco-friendly all-electric fleet. Safety is another reason for our initiative. The autopilot feature in Tesla cars adds a new level of protection. It’s one of many features that help reduce accidents; therefore, our sales team and service technicians are safer on the job. 

Tesla vehicles are reliable and convenient so our employees can be happy at work, which we know contributes to higher quality service. We also know how much Tesla means in the Bay Area. Here’s a look at the benefits of a Tesla and how it can improve a fleet.

Benefits of Teslas

Driving a Tesla doesn’t only improve safety. It has many other perks that benefit casual drivers and businesses. These benefits include:

• Impressive Battery Range: Although battery range depends on the Tesla model, driving range is rarely a problem, especially for city driving or commuting. Some Teslas are capable of traveling 320+ miles on a single charge. That means they’re suited for long-distance driving or traveling from site to site during the workday. And, with the battery placed on the bottom of the vehicle, a lower center of gravity prevents the car from rolling over.
• Save Money on Gas: With high gasoline prices, your budget can be strained by fuel costs alone. On average, a full battery charge costs less than half the price of filling up the tank. Teslas are fully electric so you never have to buy any gasoline. Charging stations can be installed in virtually any home or business, so you start your day with a full charge.
• A Large Network of Charging Stations: Tesla’s supercharger network consists of over 30,000 stations, where a 15-minute charge can yield a 200-mile range. A full battery charge can sometimes be achieved in an hour and a half or less. The company’s charging stations are known for being dependable and accessible. Therefore, charging an EV battery in the field can be achieved quickly and easily, with minimal disruption to workflow.
• More Eco-Friendly: Tesla vehicles don’t use traditional fuel. Therefore, they help reduce greenhouse gas emissions and the burning of fossil fuels. This contributes to a smaller carbon footprint. Our crews can drive around all day and not produce the environmental pollution that traditional cars and trucks do. Tesla has indeed helped Trio’s efforts to be more sustainable.
• Over-the-Air Updates: With Tesla, you need not worry about outdated features and technology. The cars are built to last. Meanwhile, software updates enable Tesla owners/operators to take advantage of new features and services as they become available. They have allowed users to interact with vehicle cameras and speakers via their cell phones. Some updates have even improved vehicle functionality by, for example, adding engine horsepower or modifying battery or wheel performance.
• Few Maintenance Requirements: Teslas require hardly any maintenance, which further reduces costs and downtime. They don’t need oil changes, spark plug replacements, or new fuel filters. The regenerative braking system used in Tesla vehicles rarely requires new brake pads. Air and cabin filters need replacement every 2 to 3 years while the AC desiccant bag lasts roughly 6 years.
• Security Features: Numerous security features are included in Teslas. Eight cameras help improve safety and also help keep your vehicle more secure. Sentry Mode helps protect your car from intruders by detecting signs of trouble and flashing the headlights to ward off unwanted guests. It also displays a message on the infotainment screen to remind outsiders they’re being recorded. 

The system sends smartphone notifications as well. An app lets you view live feeds and speak through a vehicle’s exterior speaker. Or, you can view recorded footage once you return to your car. Additionally, Teslas let you shut off certain features and lock the trunk or glove box remotely, which limits access to them by, for example, valet personnel.

Why Upgrade a Service Fleet with Teslas

Upgrading an entire fleet may seem like a big investment, but these vehicles have 5-star NHTSA safety ratings in every category. The low risk of injury means our workers are always protected. Their day is also easier. Remote diagnostics and mobile service benefit drivers by saving them time and allowing them to focus on their job duties. 

Tesla accommodates all types of drivers. The company’s fleet and business program is designed to help turn your fleet all-electric and reduce your organization’s environmental impact. You can also take advantage of tax incentives to further reduce operational costs, on top of savings on gas and maintenance expenses.

However, Tesla doesn’t only benefit your bottom line. Driving one also benefits the community. With the low probability of accidents and injuries, using features such as Autopilot contributes to safer roads. Therefore, we’re helping keep people throughout The Greater San Francisco Bay Area and the Bay Area safe.

Here’s yet another perk. California permits Tesla owners to use HOV lanes without occupancy restrictions. This allows our sales and service teams to get to work sites more efficiently.

How Trio Plans to Introduce Its Tesla Fleet

Switching to an all-electric fleet of vehicles is a big undertaking. Since we want to ensure our customers see uninterrupted service, we’re slowly converting from our gas-powered vans to a full fleet of electric vehicles. Taking a phased approach allows us to ensure the process goes more smoothly and our fleet is 100% reliable when it’s complete. Therefore we can continue prioritizing our customers’ needs and the lasting performance of their AC, heating, and indoor air quality systems.

At some point, most homeowners face the decision to repair or replace their air conditioning system. A repair is often more cost-effective up-front. However, AC replacement can have many benefits. Your air conditioning contractor can help you decide and weigh the benefits of each option. We’ll look at a few perks of replacing your AC unit and when a repair is the best choice for now.

Reasons You Should Consider AC Replacement

There are many benefits to replacing your air conditioner. While you may have become attached to your AC over the past few years, a replacement may be the right decision. These are some reasons to go this route:

• Repair Costs Are Adding Up: Even if your AC needs a minor repair, it can cost hundreds of dollars. You may pay thousands of dollars for a major repair. But even if you’re not facing repair bills that high, consider how frequently your AC requires service. To determine if a repair is worth it, multiply the estimated repair cost by the unit’s age; if it exceeds the cost of a new model, go with AC replacement. Or, if a repair costs over 50% of installation, replace the system.
• Your AC Is Aging: Most home ACs last 10 to 15 years, but depending on the system, they can last longer. However, a unit older than 10 years that requires extensive repairs should usually be replaced. Older air conditioners are less efficient to begin with, and they’re more likely to break down and require additional repairs. You’re just wasting money by fixing a 20-year-old air conditioner time and again.
• Energy Efficiency Is Decreasing: An AC works less efficiently as it ages. Also, older models weren’t designed to be as energy-efficient as modern ones. Higher energy bills are one disadvantage of keeping your aging AC going. You may also be dealing with temperature control issues. A new air conditioner provides more consistent temperatures while saving on energy each month.
• Indoor Air Quality Is On the Decline: A malfunctioning air conditioner is less effective at maintaining good indoor air quality. Excessive dust, particulates, and other pollutants can lead to respiratory and other health issues. Replacing an old AC is one of the best ways to improve indoor air quality. Newer units have more effective filters and are designed to newer standards that require homes to have cleaner air.
• Old ACs Can Be Hazardous: An aging air conditioner can be a safety risk. Worn components and faulty wiring can increase the risk of a fire. Some systems still use R-22 Freon, which depletes the ozone layer and is an environmental hazard. If your AC has a coolant leak, it’s an immediate risk to your health and safety, as refrigerant is toxic.

Can I Get By with an AC Repair?

You may not yet need AC replacement if there are issues such as:

• Warm air blowing due to a faulty or incorrectly set thermostat, dirty filter, or restricted airflow caused by clogged ducts.
• A refrigerant leak if a line can be sealed and your AC system uses the latest acceptable refrigerant.
• The air conditioner runs constantly due to a clogged filter, dirty coil, low refrigerant, or a malfunctioning thermostat.
• Loud, unusual noises are caused by a loose, dirty, or damaged part; in this case, the affected part can be cleaned or replaced.
• Restricted airflow from vents, which can be resolved by cleaning or sealing air ducts or fixing the motor or blower.

How Do I Decide on AC Repair or AC Replacement?

To make a decision, you need to determine the cause of the issue. Many AC issues, even if the system is older, are caused by simple problems. The more complex the issue or the more components it involves, the more likely your HVAC contractor will recommend AC replacement. Therefore, a technician must evaluate the extent of the damage. A repair makes sense if it entails replacing a small, inexpensive part; if the system is over 15 years old and requires a large, costly part, it should be replaced.

Air conditioner maintenance can help keep your home cool, improve energy efficiency, and avoid major repairs. Several different tasks, whether DIY or completed by a reputable air conditioning company, help your AC run more smoothly. That’s why we recommend scheduling AC maintenance at least once a year. If you want your air conditioning system to be reliable and last longer, don’t forget these tasks:

1. Check the Filter and Replace It As Necessary

Ensuring the air filter is clean is one of the most important AC maintenance tasks. Checking and cleaning/changing the filter is a simple DIY task and takes little time out of your schedule. If a filter gets blocked, reduced airflow will cause the unit to work harder and become less efficient. In a ducted system, it can also cause indoor air quality issues.

Disposable filters need to be replaced. Other filters can be removed, cleaned with running water, dried, and reinstalled. To access the filter, turn off the HVAC system and open the service panel. Most filters slide out easily, so cleaning or replacing one is a basic task.

2. Keep the Indoor Unit Clean

The indoor evaporator unit tends to get dirty over time. Layers of dirt, dust, and grime can build up on the coil and blower, reducing performance and leading to a musty or moldy smell. 

To clean the indoor unit, wipe it down with a clean cloth or feather duster. You can also spray the cloth first with a cleaning or antibacterial solution and wipe down the casing. If possible, clean the evaporator coil too. For a more thorough chemical cleaning of components inside the system, hire a qualified HVAC technician.

3. Compare the Thermostat Settings with the Indoor Temperature

One way to know your AC is working properly is to verify the thermostat setting and air temperature match. The thermostat should automatically turn the system on and off to maintain the set temperature. It should also show the air temperature, but you can also use a separate thermometer to verify the reading. If the numbers differ, check if the thermostat is properly set, if the AC needs a new filter, or if there’s an issue with the drain or evaporator coil.

4. Inspect the Condensate Drain and Clear Any Blockages

Your air conditioner collects condensation that forms during the cooling cycle. A built-in tray/pan and drain allow this moisture to be collected and directed outdoors. However, a blockage of grime, mold, algae, or pieces of insulation can cause water to back up and overflow, leading to possible odors and water damage. The drain can be cleared out using a vacuum cleaner at the end of the condensate pipe; depending on the severity of the issue, you may want to call an AC maintenance professional for this.

5. Clean the Condenser Unit and Surrounding Area

Since the outdoor unit is exposed to the elements, dirt, leaves, twigs, and other debris can collect on, in, or around it. Remove these and any items or objects nearby. Leave at least two feet of clearance on each side to avoid airflow and heat transfer issues. These simple DIY tasks can protect the condenser unit:

• Remove any nearby storage boxes, bins, or home/garden equipment.
• Wipe the casing with a damp cloth to remove dirt, dust, or plant matter.
• Clean fine debris with a vacuum cleaner and brush attachment.
• Use a garden hose to gently spray the fins clean.
• Carefully straighten any bent fins with a fin straightening tool.

6. Make Sure Your AC System Is Properly Insulated

The insulation surrounding the copper piping, which looks like a black or white foam rubber material, helps maintain thermal efficiency. This is important as the refrigerant flowing through the lines enables your HVAC system to cool your home. Don’t try to replace damaged insulation yourself. If you find material that’s broken, crumbling, or missing and exposed sections of pipe, call a licensed contractor.

7. Schedule a Duct Cleaning Every Few Years

Unlike routine AC maintenance, duct cleanings aren’t recommended often, but can help extend the life of your air conditioner. A buildup of dust and debris can restrict airflow, straining the system and causing damage or a breakdown. It can also lead to poor indoor air quality. Aside from wiping down or removing and washing grilles and cleaning accessible vent spaces, you should hire a professional with the tools and expertise to properly clean ductwork.

8. Schedule Annual Maintenance

Making that phone call or online request every year is an important AC maintenance task. A professional will visit your home to inspect your air conditioner and perform tasks such as:

• Thoroughly clean AC components
• Lubricate the system’s moving parts
• Inspect and tighten electrical connections
• Test all electrical components
• Perform a complete AC tune-up
• Replace the air filter
• Check refrigerant levels
• Check the thermostat
• Inspect the blower motor
• Look for and seal duct leaks
• Inspect the coils for frost or damage
• Clear the condensate drain line

Ductwork transports heated or cooled air from your HVAC unit to every living space in your home. To be efficient, it must be installed properly. There are many considerations for duct replacement that, if not addressed, can lead to poor AC or furnace performance and increased energy consumption. Improper installation can also reduce indoor air quality. Below, we’ll look at best practices for ductwork replacement to avoid these issues.

Use Industry-Approved Materials

In some older homes, cavities in walls, ceilings, and floors double as airways. These are not efficient carriers of conditioned air. Air ducts must be used and can be made of sheet metal, such as galvanized steel, which is strong and durable but tough to insulate. Fiberglass is pre-insulated and easy to cut and seal but is prone to wear. Flexible non-metallic materials (plastic, fiberglass, or PVC) are common and are convenient to install in corners and other tight spaces. However, they’re prone to tearing.

An HVAC technician can help decide on the best material based on the application, your home’s layout, and its heating/cooling needs.

Consider Location and Placement

Ductwork design should never be taken for granted. When in the design phase, the following factors must be addressed:

• Duct Length: Choose the shortest possible path so ducts don’t run too far to a specific area; otherwise, your home can have hot and cold spots.
• Exposure: Exposed ducts can cause extreme temperatures to affect conditioned air and strain your HVAC system. Make sure they’re placed behind walls, above ceilings, and under floors.
• Conditioned Spaces: Whenever possible, install ducts under raised floors or in a protected space known as a chase within a home’s thermal and air barrier.

Insulate Your Air Ducts

Some ductwork may run through an unconditioned basement, garage, or attic. Consult with your HVAC contractor about the best type of insulation to use. Insulating materials can be wrapped around ducts to minimize energy loss. Otherwise, heat can escape from the ducts, making your HVAC system inefficient and reducing comfort throughout your home.

Consider the Proper Duct Size

Air ducts should be the right size for your home and your HVAC system. If they’re too small, the system won’t have enough airflow to function properly. Ducts that are too big will reduce air velocity, affecting the distribution of conditioned air. 

To avoid such issues, a contractor will follow best practices such as calculating each room's required heating or cooling load and matching the proper duct size. To do this, they often use software that follows the Air Conditioning Contractors of America’s Manual D guidelines.

Perform Proper Duct Sealing

An HVAC installer uses various methods to seal air ducts to prevent energy loss and indoor air quality problems. Ductwork is typically attached in sections. The installation process then entails taking steps to minimize air leakage, such as:

• Connecting duct sections with screws and other fasteners.
• Sealing joints and seams with mastic or fiberglass mesh. 
• Using longer segments to reduce the number of pieces and connections needed. 
• Performing an air leakage test to ensure the system is airtight.

Make Sure the Airflow Is Balanced

An even distribution of conditioned air is dependent on having balanced airflow. Air balancing requires the supply and return ducts to have the same capacity, which yields neutral air pressure. It also requires having the appropriate number of supply and return registers throughout your home. This is why you need a professional who is experienced in ductwork design. 

Proper air balancing can:

• Maintain an optimal comfort level
• Improve your HVAC system’s energy efficiency
• Increase the lifespan of AC and heating equipment
• Prevent mold and other indoor air quality issues
• Avoid high energy bills and repair costs

Do I Need to Hire a Professional for Duct Replacement?
