The compressor is a major player in your air conditioning system. It is where the actual heat transfer process takes place that allows your central AC unit to blow cool air throughout your home.
If this component ceases to operate correctly due to damage, wear, age, or equipment failure, this process will become less efficient. While it is possible for an air conditioning system compressor to fail completely, it is more likely that they will provide some noticeable clues that a problem exists. Homeowners who learn to recognize these early warnings may be able to enjoy lower repair bills, fewer AC failures, and a more comfortable home.
The fan on the compressor unit is subject to wear because of the number of times the fans must start and stop during their lifespan. This level of use means that they are subject to a variety of problems including worn bearings, worn fan belts, damaged blades, and malfunctioning electrical switches.
When a compressor fan is in trouble, one of the first signs a homeowner will notice is that the conditioned air no longer feels as cool as it should. This problem can also cause the flow of air to be diminished. If the part is not repaired when these symptoms are noted, the compressor fan can fail completely and create a situation where warm air is circulated through the home.
Electrical switch failure
When your AC compressor's electrical switches begin to fail, it is common to notice noises when the component starts up or stops. While these noises may not be audible inside the home, especially with the windows closed, homeowners often can hear them when spending time on their deck or in their backyard. Noisy operation of any kind can risk further damage and should be checked and repaired as soon as possible.
Most modern central air conditioning compressors are manufactured as closed systems that should not require additional coolant during their expected lifespan. However, damage from storms, bumps, or even rodents may cause the coolant lines or connections to begin leaking. Residential central air conditioning systems that begin blowing warm air, instead of cool air may be suffering from this type of refrigerant leak and will need to be repaired.
To learn more about your entire air conditioning system, including the compressor, and what signs you might notice when an air conditioning repair is needed, take time to contact a reputable heating and cooling contractor in your area.
