How much does a central air conditioner cost installed? We answer that question in detail in this central AC price guide. The comprehensive discussion covers 4 important factors:
Each factor affects the price. When you read elsewhere that “the average central air conditioner costs $5,000 installed,” that information alone doesn’t tell you enough. For that cost, the unit could be a cheap, large and inefficient AC suitable for a large home in the North, or it could be a medium-sized, high-efficiency and high-quality model suitable for small homes in hot climates.

Factors Affecting AC Unit Price
Let’s consider those 4 important keys to central air conditioner cost. This input will allow you to determine the ac unit that is right for your home.
Not all air conditioner brands offer similar quality. Here are the top companies divided by their place in the market. We’ve put brands together in parenthesis that have the same parent company and essentially the same product lineup:
- Budget brands – (lowest cost, 12 to 16-year durability): Examples are Payne, Aire-Flo, Airtemp, Goodman and Ameristar.
- Standard brands – (moderate cost, 15 to 18-year durability): Examples are (Heil, Arcoaire, ComfortMaker, KeepRite and Tempstar), (Armstrong and Ducane), (Rheem and Ruud), (Daikin and Amana), (Luxaire, York and Coleman), (Maytag, Broan, Westinghouse, Tappan, Frigidaire, Nordyne and NuTone), Bosch
- Premium brands – (highest cost, 18 to 25-year durability): Examples are Lennox, (American Standard and Trane), (Carrier, Bryant and Day & Night)
Many sister brands make air conditioners that are identical except for the name. These air conditioner lists from Heil and Tempstar demonstrate the point.
Interestingly, all the brands in that group are owned by United Technology Corporation, the parent company of Carrier and Bryant in the premium category. This shows that UTC is seeking to capture consumers in various segments of the market. Lennox does the same thing with its Ducane and Aire-Flo brands.
Regardless of the quality niche they’re in, all brands make units in one or more of these performance categories:
- Basic performance: These are single-stage central air conditioners with a SEER efficiency rating of 13-15. They are loud and might produce temperature fluctuations or cold spots in your home. All brands make “Basic” ACs.
- Better performance: These are two-stage central air conditioners with SEER ratings of 16-19. They run on low, which is about 65 percent capacity, most of the time, so are quieter than single-stage units and cool more evenly. They’re more effective at dehumidifying your home too. Most brands make “Better” performance air conditioners.
- Best performance: These are variable-capacity central air conditioners, called modulating or variable-speed by some brands. These units have compressors that modulate by very small degrees between 25 percent and 100 percent capacity with the result that the units are the quietest, most efficient, best at removing humidity and produce the most balanced temperatures. Variable-capacity ACs have SEER ratings as high as 26. These “Best” units are made by Standard and Premium brands.
The term SEER stands Seasonal Energy Efficiency Rating. Like gas mileage ratings, SEER is a rating of how many Btu’s of cooling the unit can produce for the electricity it uses. The higher the SEER, the more efficient the unit is.
Choosing the right efficiency rating for your purposes is discussed below.
4. Size (Ton)
Each residential AC model is produced in a range of sizes. Some start at 18,000 Btu while others start at 24,000 Btu. This is a measurement of the amount of heat per hour the units remove from your home. Most central air conditioner models increase incrementally by 6,000 to 12,000 Btu. The largest residential units are 60,000 Btu.
Within the industry, sizes are also spoken of in “tons”, a term that dates to using tons of ice to cool buildings. One ton of air conditioning capacity is equivalent to 12,000 Btu’s of cooling.
2020 Central Air Conditioner Prices
(Updated on Feb 16th, 2020)
Air conditioner prices are rising for a range of reasons including higher manufacturing costs, tariffs and the fact that today’s ACs are more efficient than ever before.
Because of that, we’ve updated pricing, so here are 2020 central air conditioner prices for all brands and ACs by size from 1.5 ton/18,000 BTUs to 5 ton/60,000 BTU.
What’s In These 2020 Air Conditioner Price Quotes?
The prices in the tables include everything – a complete system.
We’ve priced them in separate columns for:
1). Just the equipment
2). The whole system installed.
Most brands including the top names like Trane, Carrier and Lennox, are sold as a package: The equipment plus installation. You can only get them from local brand dealers and HVAC installers.
We itemize equipment and installation to see where your money will be going.
What’s in a Central Air Conditioning System?
A central air conditioner system is more than just the condensing unit – the outdoor unit usually referred to as the air conditioner.
If you sign a contract for a new air conditioning system, it will (at least should) include the following.
- Condensing unit – outdoor unit
- Indoor coil – housed in or near the furnace or air handler
- Refrigerant line set to connect the coil in the condensing unit to the indoor coil
- Refrigerant to fill the system, if the unit is not pre-filled or if the refrigerant line set is longer than usual.
Central AC Prices Table – AC + Installation
The prices in these table include all the equipment and materials plus AC installation labor cost.
Note: The price ranges are very broad for 2 reasons.
1). They cover all sizes, from 1.5 to 5.0 tons
2). They cover all series from basic to better to best, plus the lowest efficiency to the highest efficiency.
For example, Carrier makes Comfort (basic – up to 16 SEER), Performance (better – Up to 17 SEER) and Infinity (Best – Up to 21 SEER). Most brands make a similar range.

Central AC Prices by Unit Size
If you know what size unit you have or need, this chart will help you narrow your cost.
We’ve included a rough idea of home size, but you cannot be sure of the size AC unit you need without a pro technician doing a load calculation, such as a Manual J, that measures 10+ factors including home size, style, construction materials, door/windows, climate and more.
Here are central air conditioner prices by size.
|AC Unit Size||Home Size||Equipment Cost||Installed Cost|
|1.5 tons||600 - 1000 sf||$1,880 - $3,460||$2,840 - $4,620|

Central AC Installation Cost and Extras
How much does it cost to install a central air conditioner?
$1,400 – $3,500 | Central Air Conditioner Installation Cost for Labor
This cost is based on many factors including:
- Brand name – Carrier and Bryant cost more than Heil and Day & Night even thought the equipment is nearly identical and all brands are owned by United Technologies Corporation (UTC)
- Difficulty of the installation
- Distance from the condensing unit (outdoor unit) to the indoor coil
- Size of the AC unit and coil – more refrigerant is needed for larger systems, and refrigerant is expensive
- Who you hire (general AC installer or brand-certified installer)
- Size of the installation company (smaller companies with less overhead sometimes charge lower rates)
- Where you live – Cost of living in your area will affect AC installation cost
This price includes everything – removing old AC equipment, if needed, setting the new condensing unit, installing the new indoor coil, replacement of the refrigerant lines and topping off the system with refrigerant if necessary.
Itemized AC Installation Costs
Here’s a breakdown of costs associated with the installation of a new or replacement central air conditioner. As noted, refrigerant line, refrigerant and indoor coil are included in the above costs.
The prices below show where your money is going – or where you might need to spend extra money for system components like a condensing unit pad, ductwork, thermostat or zoning controls.
Brand New Ductwork: If your house has never been installed with an HVAC system before, you need to pay extra money for it.
$2,000-$4,000 | Quality R-6 insulated ductwork
Related Article: HVAC Ductwork Cost Guide
Condensing unit pad: Most installers won’t put a condensing unit directly on the ground, so a pre-fab pad can be used or a concrete slab can be poured.
$20-$150 | Condensing unit pad
Refrigerant lineset: There are two lines. One carries refrigerant from the coil in the condensing unit to the indoor coil; the second returns the refrigerant to the outdoor coil. Linesets from 20 to 50 feet are produced; length affects cost.
$120-$400 | Refrigerant lineset
Evaporator coil: This indoor coil can be a cased coil that installs on top of your furnace or an uncased coil that installs in the furnace cabinet. The indoor coil, known as the evaporator coil, collects heat from the air circulating over the coil. The heat transfers into the refrigerant, and it is carried to the outdoor coil where it is released. As heat is removed from the air, the indoor coil gets cold enough to condense moisture. Drier air in summer is more comfortable. The condensed moisture is collected in a drain pan. The evaporator coil must be sized to the capacity of the central air conditioning system.
$175-$500 | Uncased evaporator coil
$225-$575 | Cased evaporator coil
Thermostat: If your new central air conditioner or complete HVAC system has features the old one didn’t, you’ll probably need to replace your thermostat. You might want to do this anyway if you currently don’t have a programmable or Wi-Fi thermostat that allows you to monitor and control your heating and cooling using your smartphone and an app.
$12-$100 | Non-programmable thermostat
$15-$124 | Basic programmable thermostat
$135-$500 | Wi-Fi programmable thermostat
HVAC Zoning Controls:
The cost of zoning system is typically around $2,000 to $3,500 depending on the number of zones. For more information, read our HVAC Zoning System Cost Guide.

What Size Air Conditioner Do I Need?
Getting the right size ac unit is essential to your indoor comfort and to the durability of the system. An AC unit that is too small will work too hard and might not cool the space effectively. This will also lead to premature mechanical failure. A unit too large will over-cool your home, creating temperature swings. The unit might also short-cycle, a malfunction that can destroy an AC compressor in the condensing unit.
Before having a Manual-J calculation made, you can get a pretty accurate estimate of the size unit you’ll need with the following information. First, find your location on this US Climate Zone map below.
Image Source: basc.pnnl.gov
The hotter your climate is, the more cooling power you’ll need per square foot of your home. This is a quick reference:
- Zones 1 & 2 (hot): 22-30 Btu/sq. ft.
- Zone 3 (warm): 20-24 Btu/sq. ft.
- Zone 4 (moderate): 18-22 Btu/sq. ft.
- Zone 5 (cool): 16-20 Btu/sq. ft.
- Zone 6 (cold): 14-18 Btu/sq. ft.
- Zone 7 (very cold): 12-16 Btu/sq. ft.
To give you an idea of how these numbers might translate into your home, let’s turn them into central AC unit sizes for an average house of 2,000 square feet in each of the climate zones:
- Zones 1 & 2 (hot): 2,000 x 24-30 = a 44,000 to 60,000 Btu (4.0-5.0 ton)
- Zone 3 (warm): 2,000 x 20-24 = a 40,000 to 48,000 Btu (3.5-4.0 ton)
- Zone 4 (moderate): 2,000 x 18-22 = a 36,000 to 44,000 Btu (3.0-3.5 ton)
- Zone 5 (cool): 2,000 x 16-20 = a 32,000 to 40,000 Btu (2.5-3.5 ton)
- Zone 6 (cold): 2,000 x 14-18 = a 28,000 to 36,000 Btu (2.0-3.0 ton)
- Zone 7 (very cold): 2,000 x 12-16 = a 24,000 to 32,000 Btu (2.0-2.5 ton)
The range in sizes is the result of factors related to your home’s construction. In short, homes with more insulation, energy-efficient windows and doors and light-colored roofing need fewer Btu’s of cooling.
Summarizing the sizing of a central air conditioner, keep in mind:
- A home in a cool climate requires a smaller central air conditioner than the same home would need in a hot climate
- A replacement AC should be smaller if the home’s insulation has been upgraded or other energy-efficiency modifications have been made
- A replacement AC should be larger if additional space, such as a finished basement or converted garage, is to be air conditioned
What Efficiency (SEER) is Right for You?
How efficient should your central AC be? If eco-friendly heating and cooling is the highest priority, then buy the most efficient system you can afford. Since the most efficient ACs are also the best performers, the answer is the same if superior indoor climate control and comfort is your goal.
When cost-efficient air conditioning of your home is what you want, finding the right balance between equipment cost and energy cost is the key. Referring to the Climate Zone chart again:
- Zones 1 & 2 (hot): 18 SEER and up
- Zone 3 (very warm): 17-18 SEER
- Zone 4 (warm): 16-18 SEER
- Zone 5 (moderate): 15-16 SEER
- Zone 6 (cool): 15-16 SEER
- Zone 7 (cool): Up to 15 SEER
The above SEERs are roughly estimated. We also developed a SEER Savings Calculator to help find a better balance between equipment cost and electricity cost.
There are a few more factors to consider.
Moist air is harder to cool, so if high humidity is common in your area, then getting a more efficient AC Units will reduce energy costs and make your home more comfortable.
The longer you intend to live in your current home, the more cost-effective a very efficient central air conditioner will be because its higher cost will be recouped when spread over more years.
If you plan to sell soon, you won’t get the long-term energy cost savings of an efficient air conditioner. However, keep in mind that some potential buyers will want to know how efficient your AC is, especially in warm and/or humid parts of the country.
