The compressor is the heart of your central air conditioning system. Almost literally, since it does a similar job to the heart in a body: it pumps a vital substance through a circulatory system that allows for an exchange. In the case of the compressor, it exchanges heat, moving heat from inside a home to outside it to cool down the interior.
Not only does the compressor perform an essential function for your air conditioner, it also consumes the most power to run. Most of the electricity you use to power the AC goes to the compressor’s motor. When the compressor fails, you’ll face two problems: an air conditioner that can’t cool; and a repair that may be too expensive to justify, leading to having to replace the entire system.
This is why watching for signs of a dying AC compressor is helpful: you may avoid an early replacement and be able to have an air conditioning repair in Katy, TX that will keep your cooling system working for several more years.
