The national average AC replacement cost is about $4,600. The total cost varies depending on the size and type of AC or HVAC unit you choose and the condition of the existing ductwork.
Apart from the varying costs of the AC or HVAC replacement itself, you will have to consider the complexity of the work and then add labor costs and material costs to the price of the AC replacement.
As mentioned, you will also have to factor in any additional ductwork. For repairing existing ductwork, expect to add about $1,000 to $3,000 to the total cost. For ductwork replacement, an air conditioner installation cost can go as high as $9,000.
An inspection – where an HVAC contractor performs a load calculation and tells you the right size of AC for your house – will add to the replacement cost. Here’s a chart for your reference:
| Total square footage to be cooled | Capacity (BTUs per hour) |
|---|---|
| 700 to 1,000 | 18,000 |
| 1,000 to 1,200 | 21,000 |
| 1,200 to 1,400 | 23,000 |
| 1,400 to 1,500 | 24,000 |
| 1,500 to 2,000 | 30,000 |
| 2,000 to 2,500 | 34,000 |
Tips for choosing the most cost-effective air-conditioning units
The cost for a 3 ton AC unit is $2,920 on average. For another tonnage prices look at the table below:

| 2 | $2,620 |
| 2.5 | $2892 |

| 5 | $3,690 |
The type of system you choose will affect your AC replacement cost. Choices for air conditioning replacements include heat pumps, ductless air conditioners, ducted split air conditioners and central air conditioning systems.
The size of the air conditioner and the cooling capacity also affect the cost of your air conditioning replacement. Larger systems will cost more than smaller ones. However, while planning an HVAC replacement, the system size should depend on the size of the space it needs to cool. A system that is too small will need to work overtime to maintain indoor temperatures, making it less efficient.
The Seasonal Energy Efficiency Rating (SEER) of an air conditioner determines how energy efficient it is. Expect your HVAC replacement cost to be affected by these ratings. The more energy efficient an air conditioner is, the more it will cost you.
Adding heating system replacements as well as additions such as air purifiers, humidifiers and dehumidifiers will affect the cost of air conditioning replacements.
HVAC replacement cost is also affected by factors like extra ductwork, repairing damaged existing ducts and adding or sealing vents.
If your existing air conditioning system is getting older, its efficiency has drastically decreased, and if it’s getting noisier or needs frequent repair work – it’s time for an HVAC replacement.
Today, newer and better AC units are quieter and more energy efficient, and they have more power than older models.
What’s more, new air conditioners must meet a minimum standard of 13 SEER. Apart from the increased cooling efficiency, a high SEER rating also saves you money on your energy bills.
Moreover, the government offers tax credits to incentivize homeowners to buy energy-efficient home products, including ENERGY STAR-rated air conditioners.
So, once you decide on an air conditioning replacement in your home, you need to know how much of an investment you need for this home improvement.
It’s also the best way to ensure that you don’t stumble across any unwelcome surprises during the execution of your project.
Acquiring a free estimate for your heating and cooling unit will help you create a realistic budget for your air conditioning replacement.
The average lifespan of an AC unit is between 10 and 15 years. Even if you have maintained your air conditioners well over the years, you will need to start considering replacing them once they become older than 10 years old. The older an AC unit becomes, the more difficult it will become to procure spares. An AC replacement may be just what the doctor ordered
If your AC has been breaking down frequently, it is a sign that you may not have been prompt in booking HVAC technicians for preventive maintenance as well as for repairs. What this also means is that the more frequently it keeps breaking down, the more you will end up spending on repairs. Planning an HVAC replacement will definitely help you save that money.
Older model air conditioners are less efficient than newer models are. Also, the older an AC unit gets, the more power it starts to draw. If you notice your energy bills spiking month-on-month with no signs of abating, it is a good time for an AC replacement.
Older air conditioners use a refrigerant called R-22 Freon, which, as of 2020, has been banned by the EPA for being hazardous to the environment. While this does not stop you from using your existing AC, it does mean you will be unable to refill the refrigerant if necessary. That means it’s time for you to start planning for an AC replacement.
Very often, homeowners feel unsure about whether they need to repair their old air conditioning unit or replace it. Here are some telltale signs that it is definitely time for air conditioning replacements.
Always hire a contractor who is certified, licensed and insured. That way, you can be guaranteed of the quality of work, and can also rest easy knowing that the contractor’s insurance will pay for any accidents and damages that may occur. A lot of homeowners disregard this, and end up paying for damages, which only adds to the final HVAC replacement cost
While planning for air conditioning replacements, it is important for homeowners to be aware of which model and brand of equipment they currently have, the serial numbers on the equipment and how old it is. That way, when you consult contractors, it will be easier for them to advise you about what would be ideal for your needs, another major factor that affects HVAC replacement cost.
Always try to hire a contractor who is trusted by friends or relatives that live around your area. Not only may you get a referral discount on the AC replacement cost, you can also rest assured that you’ve chosen someone with a reputation for doing good work.
Before you narrow down on a contractor for your HVAC replacement, be sure to ask them for references from recently completed projects. That way, you can cross-reference the quality of their work and their reputation.
Always get multiple quotes before you narrow down your search for contractors. Be extremely wary of quotes that may seem too good to be true. Chances are that the contractor may be cash strapped, and may not be able to finish the project.
It is also a good idea to always check online reviews before hiring an HVAC contractor.
Choosing the correct contractor has a lot to do with HVAC replacement cost. Very often, homeowners feel unsure about whether they need to repair their old air conditioning unit or replace it. Here are some telltale signs that it is definitely time for air conditioning replacements.
