Home Depot AC Installation Cost

Home Depot provides a huge range of products and access to installation services so that you don’t need to worry about connecting major appliances and other products up in your home, including things like blinds, baseboards, backsplashes, and even ACs.

Unlike other major appliances, the Home Depot delivery team can’t install your AC system as it’s much more complex and an on-site consultation by a third-party technician needs to happen prior to purchase. After your consultation, you’ll receive a personalized quote for your AC installation. 

Cost For Home Depot AC Installation ($2,700 – $8,600)

The average cost for Home Depot AC installation including labor and equipment is $4,200, with a range between $2,700 to $8,600. This price range is based on a typical 1,500 square foot home using a mid-range AC unit, and price is similar compared to national average of $2,900 to $7,000.

Home Depot Average$4,200
Home Depot Range$2,700 – $8,600
National Average$2,500 – $7,500
Minimum Cost$1,100
Maximum Cost$15,000

If you’re not doing a complete install and are upgrading or replacing your AC unit, the costs can range from $1,000 to $5,000 for the AC unit and $1,000 to $2,500 for the installation. You’ll need to ensure that you get a comparable or appropriate AC unit as a replacement.

Home Depot can perform an on-site consultation that checks your requirements and gives you options for the best AC units for your specific needs, even if you currently have one installed, they’ll take into account how it’s performing.

Home Depot also provides repair on AC units and can perform yearly maintenance to keep them running longer. The costs for this service will depend on your location and the available companies.

National Average AC Installation Cost Based on Size

The size of your home plays a significant factor in the overall cost of installing AC, as the bigger your home, the more power your AC unit is going to need to keep your home running cold enough. The more ductwork you’ll need in a bigger home also means a higher labor cost.

Home Size (SQFT)Average Cost
1,000$2,100 – $5,900
1,500$2,900 – $7,000
2,000$3,300 – $8,400
2,500$4,000 – $8,700
3,000$4,300 – $9,200

Buying a cheaper and less powerful AC unit can save you on costs, but the effectiveness of the unit will be greatly diminished, and the power output required of the AC unit will keep it working harder for its much shorter life.

On the other hand, if you purchase an AC unit that is too powerful for the size of your home, it can short-cycle, which means it’s turning on and off too often, and this can also cause a shorter lifespan.

Something else to consider is that homes over 3,000 square feet may require two or more AC units, so the prices can jump for every additional 3,000 square feet you need to cool down.

So having a licensed professional perform a real assessment of your home to see the exact type of AC unit you’ll need can save you money and time in the long run.

Factors In AC Installation Cost (AC Unit, Labor, Ductwork)

There are three primary factors that determine the cost of your AC installation, which AC unit you’ll need, if you’re getting new ductwork, and the labor cost involved. Typically the labor makes up around 40% – 60% of the overall cost until you get to a 3,000+ square foot home that requires multiple AC units.

AC Unit$1,000 – $5,400
Labor To Install AC Unit$1,600 – $2,700
Ductwork Installation$1,500 – $7,100

In addition to the main components that impact the price, there are a range of other factors that contribute to differences in the overall cost, even when getting it done by a major retailer like Home Depot. 

For AC installation, the work is completed by third-party contractors that Home Depot connects you with, so on top of the standard price for the contractors is the increased cost that Home Depot adds to any installation services.

The location also plays a significant factor in the AC installation cost, with labor making up 40% – 60% of the cost, there are big differences in labor costs throughout the country. This type of labor cost can also significantly increase during the hotter months when more people are requesting installation.

AC Unit Cost Factors

AC units are sized by tons, and one ton is equal to 12,000 British Thermal Units (BTUs) and can cool 450 to 600 square feet of livable space, so understanding the size of your home can help determine the size of AC unit you need and how much you’ll be spending on it.

TonsMax Home Size (SF)BTUsAC Unit CostTotal Installed
1.5 tons90018,000 BTU$1,000 – $3,800$2,100 – $5,400
2 tons1,20024,000 BTU$1,300 – $4,300$2,700 – $5,900
2.5 tons1,50030,000 BTU$1,600 – $4,900$2,900 – $6,500

5 tons3,00060,000 BTU$2,700 – $6,500$4,300 – $8,700

If you’re right on the fence for ton to home size, a general rule would be to upgrade to the next level, otherwise, factors within your home can actually reduce the effectiveness of the AC unit, and getting the right size unit can make sure that it lasts the expected length of time.

Seasonal Energy Efficiency Ratio (SEER)

Another factor in your AC unit is the Seasonal Energy Efficiency Ratio (SEER), and your AC unit should sit somewhere between 13 to 26 SEER. The higher the SEER rating on your AC unit, the more expensive it will be upfront, but the more efficient it will be long-term and save you monthly costs.

SEER RatingEfficiencyAC Unit CostTotal Installed
13 – 14 SEERStandard$1,000 – $4,500$2,500 – $6,500
15 – 16 SEERHigh$1,500 – $6,200$3,000 – $8,100
17 – 18 SEERHigh$1,800 – $6,600$3,500 – $9,300
19 – 21 SEERVery High$2,500 – $8,100$4,000 – $10,800
22 – 26 SEERMaximum$3,700 – $9,200$6,000 – $11,900

So if you’re factoring in a large home with high BTUs and high efficiency with a high SEER rating, then your AC unit is going to have significant upfront costs that may or may not make it back up to you over the course of your AC units life.

You also need to be cognizant of the requirements around SEER ratings. The US Department of Energy mandates a minimum SEET rating of 13 for Northern States and 14 for Southern States. Those mandates increase in 2023 to 14 for Northern and 14.5 to 15 for Southern States.

Ductwork Installation Costs ($2,400-$6,000)

If you’re installing a brand new AC system, then ductwork will need to be retrofitted to your home, which typically costs $2,400 to $6,600, or if you’re replacing existing ductwork that has aged out, the costs range from $1,400 to $5,600.

To get a cost estimation, you’ll be paying around $40 – $65 per linear foot for a new installation and $25 – $55 per linear foot to replace older ductwork. 

For repairs, a small job to repair existing ductwork may be $200 to $700, and you should determine the life of your current ductwork to see whether it’s better to replace it all no.

Home Depot provides maintenance on your ducts which can help extend their life, and this typically includes cleaning and minor repairs, typical costs range from $300 to $700 and $25 to 45 per vent that needs cleaning.

Types Of AC Unit Cost

Typically Home Depot installs standard central AC units with ductwork, though there are some alternative options to get your house cooler, and the prices for each can fit most people’s budgets when cooling is a priority.

Ductless Mini-Split Air Conditioning Costs ($3,000-$10,000)

A ductless mini-split air conditioning system can cost around $3,000 to $10,000 depending on similar factors to standard AC units. They have a single unit outside, and then you can control up to 5 mini-units inside in different zones, giving you different temperatures and environments to meet everyone’s needs.

One of the big benefits of ductless AC is that you have no ductwork costs, and depending on some homes, this can be a high cost, and other homes may not even allow this type of work without significant renovations, which makes standard ACs impossible at a reasonable price.

Window AC Unit Costs ($300-$1,100)

Window AC units range in price from $300 to $1,100 for a typical unit, it requires no ductwork, doesn’t cost a lot to install if you even need installation. It’s a much cheaper option to stay cool but only keeps single rooms cool, and it can’t be moved without some work involved.

Portable AC Unit Costs ($200-$900)

Portable AC units are a great option to keep costs low and typically cost $200 to $900, depending on how powerful you want it to be. Its major benefits are that it requires no installation and can be easily moved around a house to match where you need it.

It’s a perfect alternative to window AC units when space isn’t at a premium, and if you don’t need complete house cooling, it can keep your cold at night with minimum effort required.

Cost To Run Different AC Units

The Home Depot AC installation cost doesn’t factor in ongoing costs, so if you pick the cheapest option AC unit, then you may pay a lower upfront cost, but over the course of 15 years that your AC unit should last, you may end up paying more in power or replacement parts.

AC TypeMonthly Costs
Standard AC$80 – $200
Ductless AC$30 – $150
window AC Unit$12 – $120
Portable AC Unit$10 – $70

The range in prices of each AC type comes down to how powerful and how efficient your AC unit is. As mentioned above, the higher the SEER rating on your AC unit, the lower the monthly costs, but power from more tons increases the price.

Standard central AC units cost the most, and even their minimum monthly costs are on the high end of other AC types. You can also lower monthly costs on standard AC and ductless AC by having a temperature control that limits its use rather than constantly spitting out cold air.

Window and portable AC units are the cheapest, but their effectiveness is limited to a single room, so you may end up increasing costs to some degree as more people want more rooms cooled down.

If You Want to Install An AC Yourself

Home Depot provides central air conditioning installation, and that type of work can be complex and, if not done correctly, could fail to cool your home, or if you purchase the wrong AC unit, you may be costing yourself money monthly or long-term when you replace your AC unit early.

If the Home Depot costs are too much, then alternative options may be a better choice for you so that you can keep your home cool, keep costs down, and get your home cooler no.
