3 Common A/C Compressor Issues

By now, our air conditioners have been running hard for a couple of months and you may be experiencing some compressor problems. First, let me explain what your compressor does. As refrigerant cycles through your a/c system, it is constantly changing from a gas to a liquid, absorbing heat from your home and releasing that heat to the outdoors.Before the refrigerant reaches the compressor,it is a low pressure gas. Your compressor squeezes the gas molecules compressing them into a high pressure gas. This allows the refrigerant to move into the condensor where it will change into a liquid and give off heat in the process.
If your compressor fails completely, the refrigeration cycle can’t function . Because the compressor is such a major component within the a/c system, a malfunctioning system often points to a compressor problem. Below are three common problems that occur with a compressor and what to look and listen for.
1) Unit is not cooling- If warm air is blowing from your indoor air handler, this can be a sign of a broken compressor due to worn parts or a faulty motor,
2) Hard starting- “Hard starting” means your outside unit is starting and stopping frequently and is turning off before the refrigeration cycle is complete. This is often a sign that the motor that runs your compressor is not working properly or there is something wrong with the wiring.
3) Loud noises-If your are hearing loud noises coming from your outdoor unit, it may be debris or bent fan blades. However, the motor that runs your compressor is also often a source of loud noises… like a grinding sound. A grinding noise often indicates a need for lubrication or a loose bearing.
