5 Common AC Compressor Problems
The air conditioner compressor is one of the most important parts of your AC unit. It’s responsible for circulating the refrigerant throughout your system, and therefore needs to be in good working condition for your AC to function properly. If your compressor isn’t working, your AC unit won’t be able to cool your home effectively. That’s why it’s important to be aware of the most common AC compressor problems, so you can take steps to prevent them. There are a few signs you should look out for to tell if your compressor is starting to fail.
1. AC Is Making Strange Noises
If your air conditioner compressor is making strange noises, it could indicate something is wrong with the unit. Compressors are designed to run quietly, so any unusual noise is cause for concern. There are several possible causes of compressor noise, including loose parts, worn bearings, and check valves. Sometimes, you can fix the problem by tightening a few screws or lubricating the compressor. However, if the noise comes from the compressor, it may be necessary to replace the unit. If you’re unsure what’s causing the noise, it’s best to have a trained technician look at your air conditioner. Your compressor should provide years of trouble-free operation with proper care and maintenance.
2. AC Compressor Is Leaking Refrigerant
An air conditioner uses a refrigerant chemical to cool the air inside your home. This refrigerant is circulated through a system of coils and compressors to remove heat from the air. If your air conditioner is leaking refrigerant, there is a hole or cracks in the system. In most cases, this will need to be repaired by a qualified technician. However, if the leak is small, you may be able to repair it yourself using a sealant kit. While fixing a leaky air conditioner can be a bit of a hassle, it’s important to do so as soon as possible. If left unchecked, a leak can cause damage to the compressor, leading to an expensive repair bill.
3. AC Compressor Is Freezing Up
One potential cause of an air conditioner compressor freezing up is low refrigerant levels. When the refrigerant level is low, the compressor has to work harder to cool the air, causing it to overheat and eventually freeze. Another possible cause is a dirty evaporator coil. The evaporator coil is responsible for absorbing heat from the air; if it is dirty, it will be less efficient at doing its job. As a result, the compressor will have to work harder to cool the air, leading to ice buildup.
A faulty thermostat can also cause the compressor to freeze up. If the thermostat is set too low, it will cause the compressor to run for longer periods, resulting in ice buildup. If you think your compressor is freezing up due to one of these issues, contact a qualified HVAC technician for assistance.

4. AC Compressor Is Not Turning On
If your air conditioner compressor is not turning on, there are a few possible explanations. First, check to ensure the unit is plugged in and the circuit breaker has not been tripped. If the problem persists, it may be due to a faulty relay or capacitor. Sometimes, the compressor itself may be damaged, and you may need to replace it. Regardless of the cause, having a certified technician diagnose and repair the problem is important, as attempting to do so yourself could void your warranty or cause further damage. With a little troubleshooting, you can soon have your AC up and running again.
5. Compressor Is Running But Isn’t Cooling the Air
Another common issue people have with their air conditioners is that the compressor is running but not cooling the air. In most cases, this problem can be traced back to a simple issue with the unit’s refrigerant levels. Most air conditioners use a type of refrigerant called Freon, which helps to transfer heat from inside the unit to the outside air. Over time, however, Freon can leak out of the unit, causing the compressor to run without cooling the air. The good news is that you can fix this problem by simply recharging the unit’s Freon levels. However, it’s important to note that this job is best left to a certified HVAC technician, as Freon can be dangerous if not handled correctly.
Rely on Experts
The compressor is the heart of an air conditioning system, so it’s no surprise that many common AC problems are related to this vital component. Fortunately, most AC compressor problems can be prevented with some basic maintenance. For instance, keeping the compressor unit clean and debris-free is important. Cleaning the coils and the unit should be regularly inspected for wear and tear. Your AC compressor will likely provide years of trouble-free operation with proper care and maintenance.
