$555-$836 | $332-$501 |
*Figures above represent the total national average pricing for a 5-ton AC unit.
When your AC unit needs a new compressor, the cost depends on two main factors: material and labor costs. Material costs typically include the compressor price itself, which sells for a national average of $555-$836. This cost is influenced by factors like the type of compressor you buy. You may also need to pay for refrigerant and other parts or components necessary for the proper installation of your air conditioner compressor.
Labor costs also vary depending on the labor rates in your area and the complexity of your AC system. On average, you can expect to pay between $332-$501 in labor costs for an AC compressor replacement.
Typically, HVAC contractors replacing your AC compressor will need to first evacuate the refrigerant, remove the old compressor, then replace the new compressor along with any other necessary components. Then, they’ll need to recharge the system with refrigerant. Why is it so expensive to replace an AC compressor?
When you need to replace an AC compressor, you may be a bit surprised at the price. Unfortunately, since the compressor is so critical to an AC system, it can be an expensive part to replace — particularly if you have a larger central air unit cooling a larger home.
This is also not a project that the average homeowner can DIY. Hiring a professional is essential since evacuating the refrigerant, removing the old compressor, installing the new part, and recharging the system with refrigerant is a complex process. This work requires specialized knowledge, tools and experience, so labor costs are priced accordingly.
Factors that impact AC compressor costs.
In addition to paying for the AC compressor itself, any associated parts like an evaporator coil and labor costs, a variety of other factors impact how much you'll pay for a compressor replacement.
Some of these factors include:
- Tonnage and system size: If you’re purchasing a replacement AC compressor for a larger whole-home air conditioning unit with more tonnage, it needs to be larger and more powerful than one that goes into a smaller mini-split.
- Warranty: If your AC system is still under warranty, you’ll likely be able to have the cost of the part replacement covered. Always check your warranty to see what’s covered.
- Speed or “stages”: AC compressors are available in various speeds, which are referred to as stages. A single-stage compressor operates at one speed only, while a two-stage compressor can operate at both high and low speeds. A variable-speed compressor can perform at unlimited speeds and adjust to your home’s temperature demand. A compressor with more stages is often more expensive.
- Compressor type: There are a few different compressor types available, depending on your AC unit. A smaller compressor in a window unit or small central AC unit will be smaller and cheaper to install than one designed to support a central HVAC system in a larger home.
Tips for saving money on this project.
While an AC compressor replacement is best taken on by the pros, that doesn’t mean you can’t try to save money on this project. Here are a few expert tips for ways that you can save money when replacing your AC compressor:
Get a few different quotes from HVAC contractors in your area.
While you should always prioritize hiring a qualified HVAC contractor, there are likely multiple options in your area. Make sure to get quotes from a few different companies so you can compare and pick the best value. Get it inspected regularly.
Getting your AC inspected regularly can help identify potential issues with your AC compressor before it’s out of warranty. This allows you to pay the labor charge while your warranty covers the replacement part cost.
Schedule the project during the off-season.
If your AC compressor replacement is not an emergency, try scheduling it during the off-season (which is typically in the fall or spring). HVAC contractors are generally less busy during this time and may offer lower rates.
Opt for a variable-speed compressor.
Even though a variable-speed compressor costs more upfront, you’ll save money long-term because these parts are much more efficient than single-speed compressors.
Is it cheaper to replace the compressor or the whole unit?
There are a few cases where it’s cheaper to simply replace the compressor rather than get a new AC unit. If your unit is relatively new and in good condition aside from the issue with the compressor, it’s generally more cost-effective to replace the compressor alone. You may also be able to repair it easily and pay minimal repair costs.
Additionally, if your compressor is still under warranty, it will likely be cheaper than replacing the whole unit.
However, if your AC unit is older and has been experiencing ongoing issues in multiple areas, it will probably be best to replace the whole unit.
Make sure to consult with an HVAC contractor. They can tell you whether your compressor is under warranty and diagnose ongoing issues with your AC unit to help you determine the most cost-effective solution.
Cost of DIY vs. hiring a pro to replace the AC compressor.
Unless you have extensive experience in HVAC maintenance, it’s not recommended that you replace your AC compressor yourself. Even if you successfully install the part, you may void the part’s warranty if it's not installed by a licensed professional.
How long does an AC compressor last?
To understand how long you can expect your AC compressor to last, it’s best to reach out to the manufacturer or contractor that installed it. You may also be able to check its warranty, if applicable.
Is it worth replacing the compressor on an AC unit?
Replacing the compressor on your AC unit is definitely a worthwhile investment if your AC is otherwise in good working condition. Without it, your AC cannot function.
However, if your AC unit is older and the compressor is just one area where your unit is struggling, it may make sense to save money by just replacing the whole unit. This may be a higher upfront cost, but it will offer significant cost savings in the long run.
