What Are the Signs That Your AC Compressor Is About To Fail?

As the weather gets warmer, you rely on your air conditioner to keep your home cool and comfortable. Depending on where you live, summer temperatures could climb above 90 degrees. As a result, you’ll want to ensure that your system components are running at peak performance.

The compressor is a very important part of an air conditioner. It helps to circulate the refrigerant and keep your home cool. The compressor pumps the refrigerant through the system and helps to keep the pressure levels even. This is an important part of the air conditioner and helps to keep your home cool and comfortable. The most common symptom of a failed AC compressor is the inability to produce cold air. Other symptoms may include poor performance, unusual noises, and increased energy usage. If your AC compressor begins to fail, you could experience uncomfortable indoor temperatures in the summer.

While some compressor problems can be repaired, replacing an AC compressor is generally the recommended course of action. A qualified HVAC technician can help you diagnose compressor issues and offer solutions for repair or replacement. Let’s take a closer look at some signs that your AC compressor might be failing.

High Energy Bills

In general, your HVAC equipment makes up about 12 percent of your total energy expenditure each year. Depending on the season, you will probably notice some normal fluctuations in electric bills. However, if you’ve been noticing that your bills have been creeping up, and you can’t seem to pinpoint the reason, it’s possible that your AC compressor is to blame. A compressor that isn’t working properly can cause your AC unit to work harder than necessary, leading to an increase in your energy usage and, as a result, your energy bills. If you’re concerned that your AC compressor may be the reason for your higher electric bills, you should contact an HVAC technician to evaluate your AC and compressor.

Warmer Airflow

Warmer Airflow

If you’re noticing warmer air coming out of your AC system, that’s a symptom of a failing AC compressor. When your compressor starts to fail, it won’t be able to push as much refrigerant through the system, meaning the air will be hotter. If you’re seeing this symptom, you’ll want to get your compressor replaced as soon as possible. Otherwise, you’ll end up with an AC system that’s unable to cool your home properly.

Loud Noises

If your AC compressor is making strange noises, it’s likely a sign that the compressor is failing. The noises can vary but may include a humming, whining, or roaring sound. The compressor is a key component of the AC unit, and when it fails, the entire unit will likely stop working. If you’re hearing strange noises from your AC compressor, it’s important to have it serviced right away. A failing compressor can cause extensive damage to the unit and may even be a fire hazard.


As the name suggests, the compressor’s role is to compress the refrigerant, which is a chemical that helps the unit turn the hot air into cold air. Over time, the compressor’s bearings start to loosen, meaning that the fluid can easily leak through them and onto the ground. If you’re experiencing a refrigerant leak, it’s likely that your AC compressor is failing. A refrigerant leak from the compressor can cause your AC system to stop working altogether and create a health hazard. If you’re experiencing a refrigerant leak, you should have your AC compressor checked by a professional to see if it needs to be replaced.

If you notice that your AC unit is making strange noises, not cooling your home as well as it used to, or leaking fluid, then it could be an indication of a failing compressor. It’s important to be aware of these signs so that you can take action before the compressor fails completely and leaves you without AC in the middle of summer.
