3.5 tons$920
4 tons$1,000

This cost does not consider the labor that is involved. You will find that labor can be variable depending on your location. If you do not have access to a local repair option, you might find that your overall repair costs can be quite high.

You might have to pay a travel fee on top of the cost of the labor itself.

How Much Does Labor For This Service Cost?

You might be wondering what the labor will cost for this service. The size of the unit can slightly impact the cost of your labor charges in total. You should be able to find out what the labor cost is for each hour of service that your repair company will charge.

This can help you to budget for the total repair cost of your service. The average labor cost for this service is $400-$1,000. This cost can be high because you need a licensed technician to handle the refrigerant that is needed to complete the service.

The ease of access to the parts can also impact the total labor costs for your replacement service.

Is There a Difference in Cost Per Brand?

Some brands of HVAC units can have an increased cost for this service to be completed. It is easy to ask if this is going to be the cost that you should expect when you get your quote, although a good repair company will make sure to look into your unique unit and see what all will be needed to complete the repair process.


 As you can see, the brand will sometimes greatly impact the cost of the repair. This is because the access for some of these units requires that they be partially taken apart to complete the repair. Some companies also have increased costs for parts as well.

Are There Repairs That I Might Have to Pay For?

There might be other items that have failed related to your air conditioner coil failing. This is not common but it can impact the overall cost of your service. You will get a quote for expected repairs but sometimes other items are revealed to be damaged or worn out during the service.

Relay Switch$225

 You do not have to consider these other fixes a normal part of your repair process, but they can crop up from time to time. It is a good rule of thumb to have an additional $500 budgeted for your air conditioner coil replacement, just in case.

You never know what other parts might need attention when you are having an air conditioner coil replaced.

How Often Will You Need to Pay for These Repairs?

You should expect that your air conditioner coil will last 10 to 15 years. This means that the costs that have been outlined above will be required every 10 years or so. $600 every ten years or so is a small investment overall when compared to the cost of the rest of your HVAC system.

This means that you will have to have normal maintenance done on your system each year to make sure that other repairs are not needed. You can budget for the minimum for these repairs as the owner of an HVAC system, but only if you take care of your HVAC system for the rest of the year.

This means that any time that something is not right with your HVAC system, you need to attend to it to avoid additional costs later in the year or in the future.

What Are the Average Maintenance Costs for an HVAC System?

There are some expected maintenance costs that you should plan to pay for the care of your HVAC system. These regular repairs and services are just part of owning this kind of system and you should make sure that you budget for them.

There are different seasonable needs for your HVAC system, and you might find that you will need to service your system more often if you live in a place that is hot for large parts of the year.

The regular maintenance costs for your AC maintenance are anywhere from $75-$200 a year. This is for simple tune-ups. There are some companies that will offer you service contracts that take care of these needs annually for a reduced cost.

Many of these contracts are a good deal for basic care and you just pay upfront for the overall annual cost at the time of the contract.

With a contract in place, you might pay $100-$500 for annual care for your HVAC system, which will include some repairs that are outside of the tune-up category as well as care once or twice a year.

Each of these contracts will be unique per maintenance company, so you will have to look into what is included as far as services. If you are paying for repairs outside of the contracted amount for your repair contract, you can expect to pay around $50-$100 per hour for repairs.

There are sometimes repair contracts that you can enter into that are like the service contracts and are intended to cover a basic amount of repair services per year. This might not be needed for newer units or systems, but if you have an older home with an older AC unit, this might be the best choice for your needs.

What About Installing a New AC Unit?

If your Ac unit has failed, you might be wondering how much it will cost to replace the unit. This can vary per area and the size of the AC unit will impact your total cost.

Some large homes will need two medium-size AC units to cover the entire home. You should always have someone look into the specifications and square footage for your home before you assume that you can get by with just one AC unit.

The average cost to install new AC in your home is around $5,000. This does include some changes to ductwork or electrical that might be needed. If you do not need these services at the same time, your cost might be lower, in the range of $2,000-$3,000.

If you need a lot of alterations to the overall HVAC system and the unit(s) too, you can expect to look at $6,000-$7,000 for the new HVAC system. This might feel a little shocking to you if you have purchased your home with the AC already installed.

This is why it is so important to care for your AC system with annual maintenance and replacement parts as needed. The cost for the air conditioner coil seems very affordable when compared to the cost of the entire system.

Replacing Your Air Conditioner Coil is Part of Owning an AC Unit

Replacing the air conditioner coil is just part of caring for your AC unit. This can be a service that crops up from time to time and overall, it is not that expensive.

You should always remember that the cost for a new AC unit is quite high and that replacing a part once in a while when it fails is much, much cheaper than that.

If you live in an area that experiences high heat all year round or most of the year-round, make sure that you are planning to have your AC unit serviced at least twice a year.

Staying on top of the maintenance when your HVAC system is running constantly will help to keep your home cool and your AC unit from breaking down. There is no exchange cost-wise for caring for your AC unit correctly.

If you have been worried about replacing your air conditioner coil, you should feel more at ease now that you know how much it will cost on average to complete this service.
