How To Detect A Failing A/C Compressor

Before your entire air conditioning unit breaks down, your AC compressor is the first to fail. Most homeowners won’t call an HVAC professional until it’s too late and the unit has fully collapsed. Don’t make this happen to you. Take note of these signs that will tell if your AC compressor is failing.


There are different noises that come along a failing AC compressor. It all begins with a struggling start of your air conditioning system. The chattering noise on your AC is an electrical glitch when you start using your unit. The clicking and rumbling sounds are from the loosed motor within the compressor which spanks inside its housing.

Moisture Leaks

The moisture pools that you find near your HVAC system can be caused by a leaking refrigerant from your AC compressor. This is not a simple problem and may bring havoc on your health. It brings dizziness, headache, nausea and more. If not given solutions, your entire system may collapse due to an insufficient amount of refrigerant.

Reduced Airflow

Reduced airflow is another sign that your AC compressor is failing. The compressor is responsible for the cool air released in your vents. If it struggles to perform its function, there can be a noticeable effect on the cool air that you feel. But compressor is not always the reason for this. It can also be caused by a clogged airduct.

Warmer to No Cool Air

Some failing compressors affect the airflow while some affect the air produced. If the compressor is malfunctioning, it keeps on producing air but not cooling them. This is because of low refrigerant level in your compressor.  Basically, what comes out of your vents is warmer air which is very discomforting especially during the long hot season.

Knowing that these signs are not your typical DIY jobs, a failing compressor needs a thorough inspection of a heating and cooling professional. This is a complicated part because refrigerants and electrical connections which contribute to the overall performance of your AC are contained in it. That’s why only call a licensed HVAC technician when these symptoms become noticeable in your unit.
