When homeowners think about upgrades that add value, they often picture a remodeled kitchen, a new bathroom, or fresh landscaping. But some of the best improvements are the ones that make a home more comfortable day after day. Central air may not be the first upgrade that comes to mind, but it can be a feature that buyers appreciate when they’re searching for a home. So, how much value does central air add to your home? Let’s take a closer look at how this upgrade can impact comfort, buyer appeal, and resale value.
Does central air add value to a home?
The question of whether central air adds value to a home can be a bit complicated. There’s no guarantee that installing AC will lead to a dollar-for-dollar increase in your home’s price, and several factors can determine whether this upgrade is worth it.
Michael Whitney, a top-selling real estate agent serving Portsmouth and Rockingham County, New Hampshire, who works with over 79% more single-family homes than the average area agent, shares why the upgrade can add value but still may not be worth doing at the last minute.
“Does it add value? Yes. [But, if] they don’t have it, and a client asks if they should put it in prior to listing the house, I unequivocally 100% say no. Don’t waste the money,” he says.
This highlights an important distinction for homeowners: an upgrade can be valuable without directly increasing a home’s price. In many cases, central air’s biggest impact is on how buyers perceive the home.
“It adds to the salability more than it adds to the value,” adds Bob Sophiea, a top-selling agent in the Lexington, Kentucky, area who is also a historic home and luxury home specialist.
Nevertheless, some experts point to a measurable increase in value when homeowners upgrade their HVAC systems. Installing a newer, energy-efficient system with a higher SEER rating and modern features can increase a home’s value by an estimated 5% to 7%. These types of upgrades can appeal to buyers looking for homes that offer better comfort, efficiency, and lower long-term maintenance costs.
Ultimately, the value of central air depends on several factors, including your location, the condition of your home, and what local buyers want. In some areas, AC is considered an essential feature that can make or break a buyer’s interest, while in others, it may simply be a bonus.
Where central air matters most
Where you live can play a big role in how much value central air adds to your home. In some markets, AC is considered an essential feature that buyers expect, while in others, it may be seen as a nice bonus rather than a must-have.
Air conditioning seems to be a must-have in many homes across the South and parts of the Midwest. Delaware, Florida, and Oklahoma have some of the highest rates of AC ownership, with 99.5% of homes equipped with air conditioning. Other states, including Alabama, Georgia, Louisiana, Missouri, and Nebraska, aren’t far behind, with more than 99% of homes having AC.
But the story looks a little different out West. Despite their large populations, states like California, Oregon, and Washington have much lower AC ownership rates, with 78.6%, 81.9%, and 65.8% of homes having air conditioning, respectively.
A lot of this comes down to the weather and how homes were built over the years. Coastal areas in these states have traditionally had cooler temperatures and ocean breezes, so many homes were built without central air because it simply wasn’t seen as necessary. But as hotter summers and more frequent heat waves become common, more homeowners are starting to rethink the value of having AC.
The value that central air adds to your home isn’t the same everywhere. It depends heavily on what buyers in your area expect. In warmer states where nearly every home has AC, a house without it may feel outdated or less competitive. Meanwhile, in milder climates where AC isn’t standard, adding it may not lead to a big increase in sale price because buyers aren’t always willing to pay a premium for it.
That said, central air can still make a home more comfortable and appealing, even if the financial return varies. Before investing in this upgrade, it’s important to look at your local market and understand what features buyers are actually looking for.
Two identical houses: One with central AC, one without. Which one is worth more?
A new central air system may boost your home’s value by 5% to 7%, but there’s a little more to the story. Our agents say homes with central AC can often command a higher price than those without it, but the difference ultimately depends on your market and what buyers are willing to pay.
For instance, Sophiea recently purchased a cabin that does not have central AC along Lake Cumberland, but it has ductwork for air conditioning, thanks to the sellers installing a heating system.
“There are places that don’t have air conditioning, but I think it’s more of a prerequisite.” He plans to spend about $5,000 to install AC at the cabin, which he equates to a $10,000 upgrade. “When you don’t have a system, you’re looking more for an investor who’s going to add it in, and you’re going to take a discount.”
If a 1,000-square-foot cabin with central air sells for roughly $100,000, Sophiea says he’ll likely price a similar cabin without AC about $10,000 lower because buyers may see it as less desirable.
On the other hand, central air isn’t always a deciding factor in every market. Whitney explains that while multimillion-dollar homes in New Castle, New Hampshire, are expected to have AC, about 60% of new construction in New Hampshire is under $500,000, and many homes in Maine don’t have it. Because of that, he wouldn’t assign a specific value to a home just because it has central air without looking at the bigger picture.
“You don’t know what the buyer wants,” he says. “If I’m a listing agent and you come through and say, ‘My buyer is not going to buy this because it doesn’t have central air,’ I’ll say, ‘Give me a contract, and tell me you want it. We’ll put [the AC] in. Let’s agree on the price.’”
How appraisers value HVAC
When appraisers evaluate a home, they look at the HVAC system as part of the property’s overall condition, comfort, and functionality. A newer, well-maintained system can help show that the home has been properly cared for, while an outdated or failing system may raise concerns.
However, appraisers typically don’t add a specific dollar amount to a home’s value just because it has central air. Instead, they compare the property with similar homes in the area and consider whether the HVAC system meets local buyer expectations.
For FHA appraisals, the heating and cooling system must meet certain safety and operational standards before a loan can be approved. FHA guidelines generally require the HVAC system to be safe, functional, and capable of maintaining a comfortable temperature throughout the home. This means a working AC system can help the appraisal process go smoothly, especially in areas where cooling is considered a standard feature.
How much will installing central air cost you?
The average cost nationwide to install central air conditioning is about $8,750. However, pricing varies by home size, the system’s energy efficiency, and your climate, among other factors. For example, you could pay $5,800 to $14,400 to install central AC in a 2,000-square-foot home.
Ductwork can be a challenge, depending on the age of your home and the architecture, Sophiea says. The average cost of installing or replacing ductwork alone is $16 to $19 per linear foot.
Nejad Eqal, owner of Service Express HVAC in Lexington, Kentucky, which has a Google Review rating of 4.6 out of 5 stars, says a home’s size and age significantly affect costs.
“People call all the time: ‘I’m looking at this house, and it needs air conditioning. I need to know what it’s going to cost’,” says Eqal, who works with Sophiea. “The larger the home, the larger the air conditioner you need, or making it one or two systems.” Older homes with little or no insulation either need insulation or a more powerful unit.
An installer also needs to know where to place the central cooling unit, such as outside the house, in an attic, or in a crawlspace, Eqal says. An HVAC unit can be mounted on the roof of homes with limited ground space. Installation labor costs range from $75 to $250 per hour. The more difficult it is to access the cooling unit’s location, the more expensive the labor costs are.
Are there tax credits, rebates, or other incentives for installing central air?
Upgrading to an energy-efficient HVAC system can be expensive, but there are programs that can help make the cost more manageable. Depending on where you live, you may be able to save money through state rebates, local utility incentives, or the Department of Energy’s Home Energy Rebate programs.
For example, the Home Owner Managing Energy Savings (HOMES) Rebate Program rewards homeowners for making upgrades that improve a home’s overall energy efficiency, while the Home Electrification and Appliance Rebates (HEAR) help eligible households cover the cost of energy-efficient appliances and other home improvements. Since these programs are run at the state level, the rebates and eligibility requirements can vary from one place to another.
Your electric or gas utility company may also offer rebates if you install an ENERGY STAR-certified heating and cooling system. Before buying a new HVAC system, take a few minutes to check your state energy office and utility provider to see what’s available. You might be surprised at how much you can save.
How to maximize your central AC upgrade
To estimate your possible installation cost, you’ll need to decide on the system type, capacity, energy efficiency, and brand. Here’s an overview of these factors.
Types of AC systems
- Split system: If your home already has a furnace and ducts, a split system can be a budget-friendly way to add AC. The outdoor unit handles the cooling, while the indoor evaporator coil and fan sit right above your furnace to circulate cool air throughout your home.
- Heat pump: This all-in-one heating and AC unit works well in climates with moderate winters. It transfers heat through ducts from the inside of your home to the outdoors in the summer and vice versa in the winter.
- Ductless mini-split system: If your home doesn’t have ductwork or has plaster walls or original woodwork where you don’t want to install ducts, this is a good option. It also works well for open floor plans. A ductless mini-split system cools the air using an outdoor compressor and an indoor air handler connected via tubes. You can choose more than one for different areas of the house, especially if you want to set different temperature zones. Most houses have four to eight air handlers.
- HVAC packaged system: For homes that do not already have a furnace or need to replace the furnace, this incorporates all the needed components into one outdoor unit.
- High-velocity HVAC system: Similar in function to an HVAC packaged system, a high-velocity HVAC circulates air through ductwork that’s about two inches in diameter, making it a good option for tight spaces and older or historic homes. Because these systems run faster than others, they are noisier, however.
Capacity
Air conditioning units measure their cooling capacity in tons. One ton is the amount of energy required to melt one ton of ice over 24 hours. (The term is left over from the days when ice was essential to refrigeration.) You might be more familiar with BTUs, or British Thermal Units, which in AC relates to the cooling output. A one-ton air conditioner might release 12,000 BTU per hour.
In general, you need about 20 to 60 BTUs per square foot of cooling, but this again varies by climate. A professional installer can help you figure out the right AC size for your home and recommend a system that can handle your cooling needs.
Energy efficiency
Air conditioning systems also have efficiency measures that calculate how many watts the system uses. Residential systems carry a SEER, or Seasonal Energy Efficiency Ratio, specific to particular climates. SEER ranges from 13 to 24. The higher the rating, the lower the energy costs. The trade-off is that you’ll usually pay more upfront for the unit.
A 16 SEER system might cost more than one with a lower SEER, but it could reduce your annual cooling costs because it’s more efficient. Many older AC systems have an 8 or 9 SEER rating, so even a 13 SEER system will be more energy-efficient. Talk with a professional installer about any incentives such as rebates or tax credits at the state or federal level.
Don’t forget to ask about a high-efficiency filter, too. It can help reduce pollen and dust in your home while keeping your AC system running smoothly. Something as simple as replacing a dirty, clogged filter can help your air conditioner use less energy.
Experts recommend a filter with a minimum efficiency reporting value (MERV) rating of 13 for residential HVAC systems, but ask an installer if your system can handle that. The higher the MERV rating, the lower the airflow, making the system work harder and use more energy. If your system can’t handle a MERV 13 filter, go with the next lowest rating.
Brand
Air conditioner brands vary in price depending on quality, features, and longevity. Eqal prefers Rheem, which Fixr.com says costs about $3,650 to $6,450 for a three-ton unit. “We sell a lot of them. For the quality, the price is wonderful.”
Modernize, a privately owned lead-generation company that connects homeowners with contractors, compared units with 14 SEER ratings and recommended the following brands based on price, energy efficiency, and warranty:
- Trane: $6,000–$12,000 for installation costs
- American Standard: $5,500–$11,000
- Carrier: $6,000–$11,000
- Lennox: $6,500–$12,500
- Daikin: $5,500–$11,500
- Rheem: $5,000–$11,000
- Amana: $5,000–$9,500
- Goodman: $4,500–$9,500
- York: $6,000–$10,000
- Ruud: $5,000–$9,500

Is central AC truly an upgrade?
Bear in mind: Whatever you spend to install central AC won’t boost your value or asking price dollar for dollar. The typical life of an AC system is 10 to 15 years, and many buyers look at the age of the system instead of the name brand, Sophiea says.
“People always think that when they add a new system, ‘Oh, I just spent $7,000,’ but that’s not considered an upgrade. That’s considered ‘maintenance,’ or ‘the price of homeownership,’” he says. “It adds no value to the property. It helps with the salability of the property and with any issues that may come up on the inspection.”
If you live in an area that’s not particularly humid, a combination of options might keep your home cool without the expense of installing a central air conditioning system. The tips below can reduce home energy use:
- Install ceiling fans
- Install a whole-house fan
- Install an evaporative cooler, also known as a “swamp cooler,” which uses about 1/10 the energy of central AC
- Seal and insulate ductwork
- Increase attic insulation
- Install a programmable thermostat
How much value does central air add to your home?
When deciding whether central air is worth it, our experts suggest looking beyond just the potential increase in home value. Think about how much more comfortable your home will be and whether the cost makes sense for your situation. If AC isn’t common in your area or you’re working with an older home, the added value may not be as significant.
Whitney likens it to installing a swimming pool. “You can always put it in, but you can never take it back. Why would you pay for something when you don’t even know if you need it?” he says. Some buyers won’t care, “so why would you spend the money if it’s not going to make a difference?”

Frequently asked questions (FAQs) about central air conditioning
Unsure about whether to replace or install a central air conditioning system? The answers to these common questions should help.
An older unit can be up to 50% less efficient than a newer model and might use R-22 refrigerant, which is more damaging to the ozone layer, according to US News & World Report. The government is phasing out R-22 for R410a, which is also more efficient.
If your system has a low SEER rating, or if your repair costs multiplied by the unit’s age equal more than $5,000, you’re better off with a new unit. This will save you money on energy and repair costs. Plus, newer technology, such as a smart thermostat or whole-house humidifier, can help keep you comfortably cool.
Besides rebates, shop in the spring and the fall, when temperatures are milder, and the need for that blast of cold air is less urgent. Some contractors will advertise promotions during these seasons or offer an off-season discount. Get quotes from several contractors, too, to find the best deal.
Hire a licensed professional annually to change all filters, vacuum the blower compartments, drain the pan and drainage system, and clean and flush the coils. Beyond that, keep plants and hedges at least two feet away from the outside unit to avoid clogging debris.
Every month, clear any dirt and debris from the condenser coils. Clean the filters and grilles and check for drain pipe blockages. Also, seal or insulate ducts so that precious cool air doesn’t escape.
