Mistakes in AC repair and maintenance can damage the system in addition to normal wear and tear. One error or misjudgment can lead to costly problems or an early system replacement. Therefore, a qualified professional must handle any air conditioning repair (aside from changing the air filter or simple cleaning). Not calling for help when necessary, mishandling the system, or improperly maintaining it can lead to substantial damage. 

• Forgetting to Change the Filter
• Installing the Wrong Filter
• Diagnosing a Problem Incorrectly
• Ignoring Noises Your AC Shouldn’t Be Making
• Handling Electrical Parts Incorrectly
• Cutting an Electrical Wire
• Installing the Wrong Parts
• Keeping the Outdoor Unit Covered
• Waiting Too Long to Call for Help
• Not Following Safety Precautions
• Attempting a DIY AC Repair
• Not Scheduling Annual Maintenance

Avoiding these common mistakes can protect your AC system and household budget:

1. Forgetting to Change the Filter

Changing the filter regularly is the golden rule of air conditioner maintenance. Replacing it every three months or more frequently can prevent costly AC repairs. Set reminders to check the filter. If it becomes clogged with dirt, your entire HVAC system works harder to achieve the desired air temperature, increasing utility costs and straining already hard-working components.

2. Installing the Wrong Filter

As every AC professional agrees, replacing the air filter is the easiest and most important way to care for your air conditioner. However, the filter must be the right type and size for your system. Its length and width must fit the space exactly; for some units, the thickness of the filter must meet exact specifications. Otherwise, it may decrease performance or cause permanent damage.

3. Diagnosing a Problem Incorrectly

No matter who services your air conditioner, the underlying problem must be properly identified before it’s repaired. Experienced professionals have the tools to diagnose a wide range of issues. For example, leak detectors can identify damage to a coil, while voltage testers can help find a faulty electrical component. Attempting repairs without a proper diagnosis can result in overlooking the root cause of the problem. Or, the repair may ultimately be ineffective. In either case, there’s a high risk of additional damage.

4. Ignoring Noises Your AC Shouldn’t Be Making

Loud noises don’t just happen normally as your AC is running. You or anyone servicing the unit must take these seriously. Unusual noises are a telltale sign of a problem. Ignoring them can allow an issue to escalate until there’s major damage, such as a failed blower or a burnt-out compressor. Safety hazards such as a refrigerant leak or a short circuit are also possible. 

Therefore, call a local HVAC contractor if you hear the following from your AC:

• Rattling
• Squealing
• Shrieking
• Banging
• Hissing
• Whistling
• Bubbling
• Grinding
• Humming

5. Handling Electrical Parts Incorrectly

Working with an AC’s electrical components requires extensive knowledge and training. Not every AC repair technician is equipped to handle electrical issues. Attempting an electrical repair without expertise is highly dangerous. Aside from the potential for a shock, burn, or electrocution, it also risks causing extensive damage to your air conditioning system. For example, a mistake fixing faulty wiring or a capacitor can trigger a surge that shorts out major components. It can also lead to an electrical fire.

6. Cutting an Electrical Wire

Touching a live electrical part without protection, not turning off the system, or installing an electrical component incorrectly is bad enough. However, a far too common issue is cutting an electrical wire. This may seem appropriate if something isn’t working; just cut a wire, splice it back together, or replace it. 

But it’s not this simple. Your AC system has many wires and connections. Whether you cut one during repairs or by accident while trimming hedges or mowing your lawn, the results can be bad. The effects can range from reduced cooling capacity to your AC being unable to turn on. Hiring a professional is the best way to avoid wiring mistakes. They can also install and wrap wires to ensure they’re stable, protected, and unlikely to be accidentally cut.

7. Installing the Wrong Parts

Every part installed or replaced in your AC is specific to the make and model. If the wrong part is installed, it may be incompatible with the system. Your AC may not work at all, be damaged in the process, or wear out at an increased rate. Always follow the manufacturer’s guidelines for selecting parts and hire a professional familiar with your type of system. Some ACs may also require specific tools to complete certain repair tasks.

8. Keeping the Outdoor Unit Covered

Some people cover their outdoor condenser unit to protect it and avoid repairs. However, this can have the opposite effect. Outdoor units are typically built to withstand extreme temperatures and inclement weather. Don’t cover the entire unit while it’s running. The covering can disrupt airflow, overworking the unit. Or, its materials may be sucked into the machine, so you may need a major AC repair before you know it.

9. Waiting Too Long to Call for Help

Call a professional as soon as your AC:

• Doesn’t provide as much cooling
• Fails to provide consistent temperatures
• Makes strange noises it never did before
• Emits unusual odors
• Blows less air from the vents
• Has increased condensation or a small leak

Homeowners often wait too long once they notice these symptoms. But the longer you wait, the more damage can occur. Your safety may also be at risk. Therefore, call an HVAC technician as soon as possible to diagnose and resolve the issue before it gets worse.

10. Not Following Safety Precautions

An AC repair comes with many hazards. One reason to call a professional is that they know the risks and how to mitigate them. They wear protective gear such as gloves, goggles, and insulated shoes to protect themselves from harm. Other safety precautions include turning off the power while working on a system and following industry guidelines for handling, charging, and disposing of refrigerant.

11. Attempting a DIY AC Repair

Never attempt to fix your air conditioning system yourself. Other than changing filters and cleaning the outside of units, DIY repairs are far too risky. Aside from the safety hazards, there’s the chance of causing damage that requires expensive repairs. You’ll pay out-of-pocket for these if a DIY repair voids the warranty. Therefore, always call a licensed professional to diagnose and repair your AC System.

12. Not Scheduling Annual Maintenance

Another big AC repair mistake is neglecting to schedule regular maintenance. It can lead to reduced cooling performance, higher energy bills, and safety hazards. Basic professional maintenance tasks like cleaning coils, lubricating moving parts, tightening electrical connections, and measuring refrigerant levels can make a big difference. During annual maintenance, a technician can also make minor repairs to prevent larger problems that may shorten your air conditioner’s lifespan.

Many factors determine the air duct replacement cost. It’s usually a solid investment because if your ductwork is in good shape, your air conditioning system should be functional and efficient. In addition, AC duct replacement helps you get the most out of our indoor air quality services. To help you plan for improving your home ventilation system, the cost to replace ductwork (according to Angi) looks like this:

• Average Cost: $3,500
• Low-End Cost: $1,000
• High-End Cost: $9,000
• Typical Cost Range: $1,400 to $5,600

Factors That Determine the Cost of AC Duct Replacement

An HVAC contractor uses many variables to calculate the cost of a duct replacement project. The initial home evaluation is an important part of the planning process. It is when installers consider the following factors:

Size of Your Home (In Square Feet)

Although it’s not the only important factor, your home’s size is one of the first considerations. The larger your home, the more ductwork it likely needs and the more materials and labor required. Here’s a look at square footage vs. ductwork replacement costs:

• 1,000 to 2,000 Square Feet: $1,400 to $4,500
• 2,000 to 3,000 Square Feet: $2,800 to $6,700
• 3,000 to 4,000 Square Feet: $4,200 to $9,000

Amount of Ductwork You’re Replacing

The length and number of ducts to replace add to the total cost. Air ducts average $25 to $55 per linear foot. If you’re replacing multiple ducts, the installer may offer a bulk discount rather than add up every linear foot of duct. However, that depends on material and labor expenses. Large homes can require an extensive network of ducts, which requires more materials and time to install.

Placement of Ducts

Some parts of your home may be harder to access than others. For this reason, AC duct replacement can vary significantly in cost depending on the location of old ductwork. Exposed ducts generally cost less to replace than those in areas such as the following:

• Walls/Ceilings: $1,000 to $4,000
• Basements: $1,800 to $3,100
• Attics: $2,200 to $5,600
• Crawl Spaces: $3,000 to $7,300

What Your Ducts Are Made Of

Various ductwork materials are available. Some are more durable and expensive than others. Flexible ducts are the least costly, while sheet metal ducts are the most expensive. The costs of the most common duct material options are as follows:

• Flexible: Non-insulated ducts cost $1 to $3 per linear foot, while insulated ones cost $2 to $4 per linear foot. Flex ducts are generally easy to install but less efficient and heat tolerant. Insulated ones have a higher energy efficiency.
• Fiberglass: Fiberglass ducts cost $4 to $6 per linear foot and are more durable. They’re less likely to tear than flexible ducts and don’t require as much support. However, they’re not suited for tight spaces or complex ductwork layouts.
• Sheet Metal: Highly durable and long-lasting, sheet metal ducts cost $7 to $13 per linear foot. They also last the longest. Nonetheless, the installation process can be complicated by the need for additional structural support.

Cost of Insulation

The price of insulation is also factored into the air duct replacement cost. Depending on the insulating material, you may pay $1 to $8 per square foot. But materials aren’t the only cost factor here; installing insulation requires labor, so the total cost of air duct insulation can be from $800 to $2,000. Flexible fiberglass insulation is the cheapest, at $1 to $4 per square foot. Flexible mineral wool ranges from $2 to $4 and rigid or foam board fiberglass insulation is $4 to $8 per square foot.

Labor

As with any HVAC project, labor makes up a large percentage of the cost of AC duct replacement. A contractor can have a set rate per hour. Or, labor fees may be determined by the type of duct, accessibility, materials, and other factors. You may also pay to have old equipment removed and for ductwork planning and design.

Cost of Ductwork Add-Ons

Installing ductwork often involves additional modifications. Depending on the job requirements and your home’s layout, the cost to replace ductwork may be increased by the following:

• Vents: If you add vents, expect to pay $250 to $500 for each. The number of vents needed depends on your home's size and layout. Adding vents can improve circulation but lower the overall efficiency of your HVAC system.
• Sealing: Duct sealing, depending on whether each air leak is sealed manually or the system is treated with a powdered sealant, can range from $400 to $2,700.
• Lining: A durable protective lining called duct armor can add $5,000 to $30,000 to the air duct replacement cost.

Other Costs

Replacing ductwork can be complicated. You may pay other costs aside from installing air ducts. Those that may factor into your overall project budget include:

• Permits: Major home improvements like air duct replacement often require a permit. Depending on your municipality, obtaining a permit can cost $250 to $1,500.
• Ceiling/Drywall Repair: Breaking through walls and ceilings takes time and effort as does repairing and repainting them. Drywall repair can add over $300 to the cost of the project and ceiling repairs can cost as much as $1,200.
• Asbestos or Mold Abatement: Asbestos or mold testing can cost several hundred dollars each. If any of these problems are found, asbestos removal can add up to $2,200 and mold remediation can add up to $6,000 to the cost of AC duct replacement.

Frequently Asked Questions

Can I Install Ductwork Myself?

Even if you’re good at home DIY projects, duct replacement is better left to a professional. It not only requires precise measurements and cutting. You could violate building codes and local laws, not to mention cause issues such as air leaks, reduced energy efficiency, and damage to your heating and cooling system. Trying to cut costs with DIY duct replacement can also affect your homeowner’s insurance and void the warranty on your entire HVAC system.

What Are the Alternatives to a Complete Ductwork Replacement?

If leaks or other issues are isolated to a specific duct, you can replace only the worn or damaged components. This is a cost-effective way to restore your ductwork. We can work with you to make specific improvements or replace ducts in a room or area being remodeled.

A thorough cleaning can also be an effective duct replacement alternative. If the main issue is debris, dust, or mold, a contractor can address it and the cause. A professional duct cleaning can have many benefits, including restoring optimal airflow and reducing energy bills. In addition, isolated leaks and loose connections can be sealed to address various problems.

How Can I Reduce the Air Duct Replacement Cost?

Air duct replacement can be a costly home improvement project. However, that doesn’t mean there aren’t opportunities to save. You can cut costs or get more out of your investment by doing the following:

• Invest in insulated ducts to achieve long-term energy savings.
• Compare multiple quotes from reputable HVAC contractors.
• Bundle duct replacement with AC installation and other home services.

You can also reduce costs by maintaining your existing ducts, which may increase the time before air duct replacement is needed. Sealing air leaks when you discover them can limit energy loss and thus keep expenses down.

Getting air duct installation right improves comfort, energy efficiency, and indoor air quality (IAQ). Ventilation is one of the core components of any HVAC system. Your ductwork provides passages for conditioned air to flow to each room and return to the system to be heated or cooled again. It’s often the source of IAQ issues. Therefore, achieving improved indoor air quality in your home starts with proper air duct installation. 

The following tips for installing ductwork can help improve IAQ and make your indoor air healthier to breathe:

Place Ducts Within Conditioned Spaces

Contamination from the attic, basement, or crawlspace can compromise indoor air quality. It’s often caused by duct leakage in these unconditioned areas. Installing ductwork in conditioned spaces instead limits access to pollution, even if there is a leak. It also minimizes heat loss. To achieve these benefits:

• Install air ducts in a dropped ceiling or chase.
• Place under-floor ducts in open-web floor joists (in a multi-story home).
• Put the air handler in an interior utility closet.
• If installing an air handler in the garage, place it in an air-sealed closet.
• Ensure the attic or crawlspace is unvented, air-sealed, or insulated at the perimeter.

Enclose Attic Ducts In Insulation Wherever Possible

If you can’t install ducts within the building envelope, bury them as deep as possible in attic insulation. Using R-8 or higher insulation can prevent heat loss and condensation, especially when it’s hot and humid (or at least R-13 in climate zone 3a, which includes the Greater San Francisco Bay Area). 

This method is just as effective as installing ducts in a conditioned space. The International Residential Code (IRC) was updated in 2018 to reflect the benefits of buried ducts. It also requires ceiling insulation above and below them to be at least R-19.

Choose High-Quality Ductwork Materials

Subpar ductwork materials can affect IAQ, especially improper insulation. Poor insulation inside air ducts can cause temperature imbalances that lead to condensation and mold growth. Mold spores can then be released from the ductwork and spread throughout your home. Dust, pollen, and other external pollutants can also get into ducts that aren’t properly insulated.

The material a duct is made of matters as well. While easy to install and corrosion-resistant, aluminum ducts aren’t very strong. They’re also vulnerable to thermal expansion and prone to damage that can affect indoor air quality. Flexible ducts can also cause issues. They must be installed properly or else tearing, crimping, and sagging can cause airflow and IAQ issues. The more sustainable materials to consider for air duct installation include:

• Galvanized Steel: Sheet metal ducts are non-porous, reducing the risk of mold. They’re also strong, durable, and non-combustible. They are available as rectangular ducts that more easily fit in limited spaces and round ducts that maximize airflow capacity.
• Fiberglass: Fiberglass insulation is often used in sheet metal ducts to prevent condensation. Fiberglass ducts are highly insulative, corrosion-resistant, and block sound from HVAC components and other sources.
• Fiberboard: Fiberboard ducts consist of resin-bonded fiberglass strands. A foil covers the exterior and provides an air and moisture barrier. While the interior isn’t smooth like metal, fiberboard is airtight so long as joints and seams are properly sealed.

Install a Filter at the Return Intake

Return air should be filtered at the last possible point before it reaches the fan. The ideal location is where the return duct connects to an HVAC unit’s intake. A filter here can capture particles from any source, ensuring clean air and protecting mechanical components.

Return grille filters are different. They cover vents that suck air from a room that’s pulled back into your HVAC system. However, they don’t protect against contamination from leaky ducts. Leaks in return ducts beyond the filtration point can pull air and pollutants from the basement, garage, attic, crawlspace, or outside. Properly installed ducts and a well-placed return filter prevent dirt, mold, asbestos, rodent feces, lead dust, and fumes from paints and solvents from getting pulled into the system.

Make Sure All Filters Are Properly Sized

People often think high-efficiency filters block airflow and cause pressure drops in their ductwork. However, a high-quality filter shouldn’t have much of an impact. The Minimum Efficiency Reporting Value (MERV) measures how well a filter captures airborne particles and common pollutants. A MERV 13 filter is considered highly efficient. Despite a thicker filtration media, such a filter works best if it’s well-constructed and fits the filter area (so no air can get around it).

Use Mastic to Prevent Leaks

Mastic can be used during air duct installation to seal all joints and seams. It’s also easier to put on ducts during installation when you have full access to your ductwork. When properly applied, mastic can minimize air leakage over the long term, as it’s resistant to deterioration and doesn’t lose adhesion.

Install an In-Duct Air Purifier

In-duct air purifiers serve as whole-home air filtration systems. They include ultraviolet (UV) air purifiers that neutralize germs and odors in your home. Ionization air purifiers are also available. They electrically charge air molecules, causing dust, smoke, and other particles to bond with them and fall to surfaces where they can be wiped or vacuumed away. 

Installing an air purifier during air duct installation ensures you benefit from clean air right away. It can also prevent dirt from building up in ducts in the first place.

In addition to improving indoor air quality, an in-duct, whole-home purifier can have the following benefits:

• Increased Energy Efficiency: Fewer particles and buildup in your ductwork means air can flow more smoothly, allowing your HVAC system to work more efficiently.
• Fewer Repairs: Dust and debris in ducts can make their way into blowers, compressors, and other components; efficient removal can avoid damage and increase the system’s lifespan.
• Reduced Maintenance: Clean, properly installed ducts help reduce repair costs and the need for professional air duct cleaning, which averages a few hundred dollars.
• Smoke-Free Home: If your house has a chimney, smoke can get through air vents. An in-duct air purifier neutralizes smoke before it pollutes indoor air.
• Cleaner Air: High-quality air duct installation, along with a whole-home purifier, can mean bacteria, viruses, fungi, pollen, animal dander, and other contaminants are removed before they can cause allergy symptoms, respiratory problems, or illnesses.

Ignoring AC maintenance recommendations is a bad idea. Air conditioning specialists suggest having your system inspected, cleaned, adjusted and, if necessary, repaired annually to avoid problems. Your AC unit works hard to provide cool air, especially during the warmer months. It’s best to schedule routine air conditioning service before the heat sets in. If you don’t get AC maintenance before then, it increases the risk of the following issues:

Reduced Efficiency/Higher Energy Bills

Without regular care, reduced AC efficiency is a sure bet. The issues a technician would address can cause a unit to work harder, which uses more energy and raises utility bills. Professionals in the HVAC industry have estimated that efficiency can decrease up to 5% each year you skip AC maintenance. This means the unit will become increasingly more expensive to operate.

More AC Repairs

A lack of maintenance can lead to more frequent breakdowns, emergency calls, and repairs. These cost you money each time, not just to repair/replace worn components But also the cost of labor and other service fees. 

System cleanings, adjustments, and minor fixes help resolve issues rather than let them worsen over time. With a well-maintained unit, you can avoid most of the repairs you’d otherwise need. And, rather than spending money to fix your AC, you can save it for a home improvement or a vacation.

Shorter AC Lifespan

In addition to frequent repairs, skipping maintenance can lead to breakdowns that require replacing the unit much sooner. The more parts that wear out, the more inefficient the unit will become. Eventually, the entire system wears out prematurely. An AC with no maintenance may last 7 or 8 years. If well-maintained, it can last 10 to 15 years or longer, so you spend much less on AC equipment over time.

Decreased Cooling Performance

Long before an unmaintained air conditioner fails, it will continue running but become less effective at cooling your home. You might have to keep setting the thermostat lower to stay comfortable. Eventually, cold air may be hard to come by and the AC starts blowing warm air no matter the setting. Or, the temperature may fluctuate randomly and some rooms may be chilly while others are warm. These issues can occur for various reasons; AC maintenance usually prevents them.

Poor Indoor Air Quality 

Dirty air is another reason HVAC maintenance is necessary. Without routine service, your AC can get dirty quickly. Regular service includes cleaning various components so dust, dirt, and other pollutants don’t get into the air. Once they do, these can circulate throughout your home again and again. 

The contaminants in your airflow can include pollen, dust mites, chemicals from cleaning products, smoke, and volatile organic compounds from carpets, furniture, and other items. A lack of AC maintenance can also prevent the system from removing moisture, so increased humidity contributes to indoor air quality concerns, leading to anything from discomfort to allowing mold and germs to thrive.

Improved air quality is certainly a reason to follow your HVAC contractor’s recommendations. However, it must also be addressed between maintenance visits with the following:

• Replace air filters every 1 to 3 months
• Vacuum dust and pet dander regularly
• Open kitchen and bathroom vents
• Open windows to let a fresh breeze in
• Choose natural cleaning products

Clogged Air Filters

A clogged air filter can restrict airflow and cause your AC to shut down. Changing or cleaning the filter, depending on the type, is one of the easiest AC maintenance tasks you can do. It is also among the most beneficial. 

A dirty filter not only increases strain on components, but the impacts of reduced airflow and performance can cause the coil to freeze, leading to melting water that can damage your AC and home. Other risks include mold, an overheated compressor, and broken coils.

Water Leaks

If the drain line becomes blocked, moisture the system has removed can back up and leak around your air conditioner. Water can damage your AC, furnishings, flooring, and the underlying framing. Fixing water damage is often expensive. It can also lead to extensive mold problems. Flushing the drain line and cleaning the drain pan doesn’t take long and can save you lots of time and money.

Refrigerant Leaks

If a hissing noise or chemical smell accompanies reduced AC performance, a refrigerant leak is likely. The leak will reduce refrigerant levels until the system can’t absorb heat and transfer it out of your home. It may also expose you to a toxic substance that can cause:

• Headaches
• Dizziness
• Nausea
• Breathing issues
• Loss of consciousness 
• Death 

Therefore, AC maintenance can save your life.

Dirty Air Ducts

Once dirt gets into air ducts, it can stick to surfaces, increasing friction and reducing airflow. Or, it can get blown around. Dust can collect on vents and blow into rooms, where it can be inhaled, settle on surfaces, or get sucked back into your HVAC system via return vents. 

Whistling noises are a sign of dirty air ducts. You’ll need a professional duct cleaning to address the problem. Otherwise, serious damage to the system can occur. Regular maintenance helps protect your ductwork and keep it clean.

Voided Warranty

Chances are, your AC manufacturer requires professional maintenance as part of its warranty terms. Skipping even one maintenance visit can void the warranty. You won’t realize the hassle this can cause until you have to pay out of pocket for a major AC repair. The cost of following AC maintenance recommendations is far less than dealing with this situation.

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.
