Why Is Replacing My AC Compressor So Expensive?

In regards to an AC compressor replacement cost, a huge factor relates to the speed of the compressor. The HVAC industry refers to the system's speeds as “stages.” Simply put—the more stages in the AC compressor, the higher the price tag. If the unit works at a faster speed, that means greater efficiency and a boost of comfort for the home. That said, if you choose a more budget-friendly AC compressor, you may see a drop in comfort. However, since a new AC compressor cost can be very high, this can be a tough decision to make.

Not sure what kind of speed your AC compressor has? Here are the common AC compressors out there, including the stages they include:

• Single-stage compressor: One speed
• Two-stage compressor: Two speeds
• Variable-speed compressor: Unlimited speeds



As you can see, there are some different options for AC compressors. Unfortunately, if you have a unit with multiple compressors, the replacement bill can be high.

Another important factor regarding price involves if the AC compressor is still under warranty. If it is, you won’t even have to pay for a replacement compressor! But if it’s not, you’ll probably have to fork over the entire AC compressor replacement cost.

When purchasing your AC compressor for the first time, buyers typically receive a warranty. While it varies, many air conditioners come with a limited parts warranty that typically lasts around 10 to 15 years. That said, if you’re due for a new compressor, you should first check if the warranty is still valid. If it is, you’re in luck! All you need to do is pay for the labor of the installation.

So you may be wondering if an AC compressor replacement is always included with a warranty. While not every warranty is the same, most of the parts warranties out there will cover a new AC compressor cost. However, there are many instances in which your warranty can be voided, which means you’ll be responsible for the replacement price.

One common issue is that many people fail to have their AC unit properly maintained. If your air conditioner isn’t maintained yearly, many manufacturers will void your warranty. This goes to show you the importance of AC maintenance. As system parts can become damaged or wear out over time, air conditioning maintenance can ensure these issues are handled. If you don't schedule this service every year, don’t expect any warranty coverages.

Another simple thing to forget is to register your air conditioner with the manufacturer. In many cases, this is the only way to use your warranty. That said, if you fail to register, you may have to pay for an AC compressor yourself.



One other problem people run into involves trying to use a warranty when your AC unit has been repaired with off-brand parts. For example, if you have a Carrier air conditioner with a few Goodman replacement parts, Carrier probably won’t grant you the warranty. That said, if you want to keep your warranty valid and reap the benefits of a free AC compressor, only replace your AC unit with parts of the same brand!

Not sure if your AC unit is still under warranty? To find out, get your system’s serial number and model, which is found on the outdoor unit. Then, go to the manufacturer's website or give them a call, and supply them with this information.

While many central air conditioners look similar, they aren’t all the same size. This is another key factor that helps to determine the AC compressor price. While it doesn’t only impact the cost of the AC compressor itself, it can also affect the cost of labor.

If you have a large AC unit, then you can expect an expensive AC compressor. That’s because this part is needed to circulate the refrigerant through the entire system. As more parts are needed for the large unit to run, replacement components will always be more costly. If an AC unit has a high price tag, you can expect the AC compressor to be the same.



Not sure about the size of your AC compressor? You can find this out by learning the system’s model number. After finding the number, which is usually found on your outdoor unit, enter it in the manufacturer's website. You should then be able to see the size of your system. You can also ask a professional HVAC expert for assistance.
