Signs Your Compressor Might Need to Be Replaced


When your AC unit is on the fritz, it may be a quick fix or it may be something more serious, like the compressor.  The compressor is an important part of the AC unit and is critical for cooling the house properly.  It’s the job of the compressor to pressurize the refrigerant so it can absorb the heat and release it outside.  A broken compressor can be an expensive AC repair that may even require completely replacing your AC unit. If you recognize any of these signs, call a professional right away.

Improper Airflow

If your air conditioner is blowing hot air and not cold air, then this is a tell-tale sign that your compressor may be bad.  When the compressor is not able to pump refrigerant through your system, it won’t cool down the air, signaling that it is time for an AC repair.  Weak airflow is another sign that the compressor is not functioning properly.  If the air vents aren’t putting out enough airflow, the compressor may be to blame.  Should you experience any of these signs, call an AC repair technician right away to diagnose the problem so that you can have a cool, comfortable home once again. 

Loud and Unusual Noises

When the compressor is about to go out, you will begin to hear louder than normal noises coming from the unit.  If the AC vibrates when it turns on, it may be “hard starting” because it is having trouble turning on.  This is what happens right before a compressor goes out, so be aware of these vibration noises. Grinding, squealing, or any other sound that just isn’t normal means it is time to get your air conditioner looked at by an experience AC repair technician. While noises can be the result of electrical problems or even a loose fan, it is wise to have an experienced technician investigate so that you don’t risk further damage or possible compressor failure.  Unusual noises are not something to wait out or mess around with.  Waiting to have your unit fixed will lead to more expensive repairs or maybe even needing to replace the entire unit.

Temperature Change

You know your AC is set to a lower temperature, but your house is hot and won’t cool off.  A bad compressor could be to blame.  Try turning down the thermostat to get the compressor to kick on, but if it still won’t, then the compressor has more than likely already failed.  The fan could be running and you might hear noise from the unit, but the compressor will not be operating.  Any time you suspect it could be malfunctioning, call a trusted AC repair technician for an inspection.  If your AC is an older unit, then it may be wise to just replace the unit instead of investing in an expensive compressor fix.  Be aware of the signs and inform a technician right away if the compressor is not functioning properly and cooling down your home.
