What is a Compressor?
The air conditioning compressor motor is a steel-encased container that functions as a pump for your AC system. If the compressor fails then your entire air conditioning system will be unable to perform its duty to cool down your home. The pump draws in refrigerant gas that is laden with heat from the inside unit of your system and it compresses the refrigerant gas (which is a low pressure gas) to a higher temperature and a higher pressure. When this gas refrigerant enters the air conditioners condenser coil it is rapidly cooled into a liquid state. The heat from the gas is then transferred to the outside unit and is blown out into the air. The cooled refrigerant then returns to the indoor unit to continue to the interior of your home. When the systems compressor fails, the refrigerant is not able to be pushed to where it is needed and your air conditioner is essentially useless at that point.
Some of the signs that your ACs compressor might be to blame are as follows:
- Your ACs exterior fan is spinning but cool air is not blowing through the vents.
- The fan and the compressor are both not running.
- When the compressor powers on it trips your circuit breaker or blows a fuse.
- Nothing happens at all when you turn your air conditioner on.
- A major clue that you are headed for an air conditioning compressor repair is that the compressor hisses, hums, or makes a loud squealing noise when it is turned on.
Compressors will occasionally come off of their mounts. In a case like this, it is generally a quick and easy fix by just reattaching the compressor and testing it to make sure that everything is fully operational.
What Can Cause Your AC compressor to Fail?
- The fuse or the circuit break might blow for any number of reasons, including a power surge caused by a severe weather storm.
- If your air conditioning system has low levels of refrigerant fluid it could quickly overheat the motor, causing it to burn out.
- If the insulation of the motor is corroded, the compressor will also burn out.
When your licensed and trained service technician arrives he will be able to make short work of your air conditioning compressor repair job. He will also be able to help ensure that everything else is fully operational so that you can avoid another potential break down of your system. While it may seem like common sense, he may ask you when you last changed your systems filter. A surprisingly large number of homeowners simply dont remember to routinely change out their air conditioners filter. So be sure that you make a note to complete this task every 3 to 6 months!
