Central AC installation cost factors
Ductwork cost
AC installation costs can also vary depending on what you need to get done in your home. For example, do you need new ductwork? The national average cost ranges from $1,391-$5,846.
Home size
The bigger the house, the more ducts that will need to be run, checked and sealed. The increased need for cooling power will cause the new AC unit to cost more, too. And there's more than one story in the house, running the ducts, pipes and wiring may add to the cost as well.
Home's age
Older homes often don’t have existing ductwork because they weren’t designed for central AC. Therefore, to install an air conditioning unit, you might need a new system of ducts — and that can get expensive.
On the other hand, some units don’t need ductwork, so they can be installed without this added expense. Keep in mind that each installation is unique, and the complexity depends on the needs of the house and the desired location of the unit.
Packaged air conditioners vs. split systems
A packaged air conditioner combines heating and cooling and, unlike split systems, they’re enclosed in a single cabinet — which helps save space. These systems tend to cost less than split systems because they're easier to install.
In addition to packaged ACs, examples of other packaged HVAC systems include:
Packaged heat pumps, which can heat and cool your home.
Packaged dual fuel system, where the heat pump acts like an air conditioner, and the gas furnace goes to work when temperatures get too cold.
Packaged gas/electric systems, which use a furnace and air conditioner.
A packaged system is useful for its versatility. It can be put on the roof or next to your home. But because the system has to sit outside, it’s fully exposed to the elements. Freezing water and outdoor debris can cause the system to malfunction. If something goes wrong, you may lose both your heating and cooling.
If your home doesn’t have an air conditioner, but there's a furnace, you might consider installing a split-system air conditioner. It’s the most common type of central air conditioner for residential homes — and usually the most affordable. With a split-system AC, you have an outdoor unit or cabinet containing the condenser and compressor. Inside, you have another cabinet with the air handler. The indoor unit can also contain a furnace or heat pump.
If you’re thinking about getting a split-system HVAC, here’s how these systems are configured:
Furnace and air conditioner: Most HVAC systems use a gas furnace instead of an oil one.
Furnace and heat pump: These are recommended for colder climates, and are also called “hybrid” or “dual fuel systems.”
Air handler and heat pump: These are recommended for warmer climates, and are sometimes called “heat pump split systems.”
A split-system air conditioner provides effective heating and cooling while keeping part of the unit inside your home. It’s easier to service this section of the system, as well as protect it from the elements. However, you still have to depend on a series of wires and pipes that connect the various components. If any of these fail, the repairs can get expensive.

Is it worth replacing an air conditioner?
In many cases, it's worth replacing an air conditioner. For example, a new AC unit can help you save money on energy and cooling costs. Potential homebuyers will also want to ensure your home has functioning and energy-efficient HVAC system before buying.
If you're not sure if you should replace or repair your AC unit, take the following the steps:
Get repair and replacement estimates. If the repair is minor, it's probably not worth it to replace your AC right away. In some cases, the cost of the repair will not be worth the cost of a new AC unit.
Figure out how old your unit is. According to the International Association of Certified Home Inspectors, a central air conditioner lasts 7-15 years. If your system is older than that and it keeps malfunctioning, it may be time to consider replacing it.
Does it need frequent repairs? Even if the repairs are small, they will add up over time — and that cost might be higher than the cost to replace your unit.
Review your energy bills for spikes. This is a sign that your AC is not as efficient as it used to be. A repair may be needed, or you may need to upgrade to a more energy-efficient model.
AC service cost
After you install your new AC unit, you'll need to factor in the cost to service, clean and maintain your unit. The national average cost of routine maintenance is $99, and prices range from $79-$189.
| National average cost | $99 |
|---|---|
| Average low-end cost | $79 |
| Average high-end cost | $189 |
How to lower your AC costs
There are a many ways you can save money while using your new AC unit or HVAC system. For example:
Focus on energy efficiency. Only run your air conditioning system when you need to and utilize the thermostat. Running your AC unit when you’re not at home can waste significant money.
Program your thermostat to turn on when you’re either at home or when you are on your way back from work, school or another place.
Seal cracks and insulate your home. If your house lets in warm air from outside, you’re making your unit work harder than it should. This requires more electricity and, consequently, more money. Insulating your home and sealing cracks can help cut down on your AC’s workload.
Change the filters. Clogged filters inhibit airflow, forcing the unit to work harder and expend more energy. Clogged filters can also damage your unit, so keeping them clean will help you save money on replacement parts as well.
How to hire an air conditioning professional
First, make sure the installer you choose has the proper license and credentials to install an air conditioner in your state. You should also read testimonials from past customers, and see if the installers received positive reviews for providing tips during the inspection, being punctual, exhibiting professionalism and cleaning up any mess that was created.

FAQs
These are some frequently asked questions about central air systems, AC units and HVACs.
How much is a new AC unit for a 1,500-, 1,600-, 2,000-, 2,500- and 3,000-square-foot house?
First, you'll need to figure out the appropriate size for your AC unit. An old rule of thumb was that an HVAC should provide 1 ton of cooling/12,000 BTUs for each 400 to 500 square feet. However, the DOE insists that you use the Air Conditioning Contractors of America Manual J to figure out the ideal size for your unit.
Typically, AC companies don't go by square footage to size an air conditioner unit. Instead, your contractor will take other factors into account, including: windows, doors, ceiling height, insulation and other details. Always ask your HVAC contractor to provide AC cost and size estimates for your home.
How long should an AC unit last?
A central air conditioner typically lasts 7-15 years. Here's how long other components of your HVAC system tend to last:
| HVAC component | Estimated lifespan |
|---|---|
| Air exchanger | 15 years |
| Boiler | 40 years |
| Condenser | 8-20 years |
| Evaporative Cooler | 15-25 years |
| Furnace | 15-25 years |
| Heat Pump | 10-15 years |
| Thermostats | 35 years |
Can I just replace my outside AC unit?
Yes, you can replace just your outside unit — but this usually only works out if your AC unit is relatively new (just a few years old) and the warranty is still valid and allows you to find a compatible unit. However, if you're replacing an old outside AC unit, HVAC contractors will most likely recommend that you also replace your indoor AC unit. Here's why:
Your indoor unit may not be compatible with your new outdoor AC unit. For example, SEER ratings maybe have changed since when you bought your system.
A system with mismatched components may break down or lose their inefficiency.
If your mismatched system breaks down, it will likely cost you more money in the long run.
In most cases, you'll want to replace your entire AC unit. If you still have questions about replacing your outside unit, contact an HVAC contractor in your area today.
Should I replace my 20-year old air conditioner?
Check with your contractor or technician. If your AC is older than 10-15 years, it may be time to upgrade and replace it.
Does homeowners insurance cover AC units?
You'll need to check your policy to find out if insurance covers your air conditioning unit. Typically, insurance will take care of damages caused by trees, fires and other perils. However, they usually don't cover normal wear and tear.
What is an HVAC, and how does it work?
HVAC stands for heating, ventilation and air conditioning. An HVAC unit helps your home maintain a comfortable temperature level, thanks to its heating system and cooling system. These systems include many different components (AC unit, heat pump, boiler, furnace, fans, filters, etc.).
An HVAC system can do a good job of providing central air for your home. To install an HVAC system, you’ll need to get the right kind of unit — a packaged unit, split system or heat pump. You might also need a system of ducts and vents if you don’t have them already. And, you’ll also need to get a thermostat, which helps the system switch between providing cool air and heat.
What is the labor cost to install central air?
The labor cost to install a central air conditioning system will vary. It depends on the HVAC installer and your location.
Can I install central air myself?
To install central air, in most areas, you need a special license or certification. Unless you have that license, you can’t do it yourself. The specific license you need varies by state.
When looking for a professional who can do the job for you, make sure the HVAC installation pro has the appropriate license and credentials.
Is central air worth the cost?
It would be worth the cost if you want the comfort and convenience of having a whole-house system. Central AC in warmer areas is also valuable because many need it to maintain an adequate quality of life. If you live in a colder area where the summer temperatures rarely get above 80 degrees, it may not be worth the cost because you may not need it for the vast majority of the time.
Does central air add value to a home?
Yes. Having central air can increase the value of your home by as much as 10 percent, according to some experts. Even in homes where central air is rarely used, people considering buying a home value the extra convenience of having it available.
How long does it take to install an AC system?
If you're simply swapping out an existing unit — with no ductwork required — expect your installation to take about a day. If your installers need to replace ductwork, you're looking at, on average, a three- to a five-day job.
But keep in mind that more complicated jobs will add time. If you're installing a unit on your roof or if your home is three stories tall, that estimate could dramatically increase.
How long does HVAC installation take?
A typical residential HVAC installation takes between one and 14 days, depending on the complexity of the job.
