The compressor is the heart of your air conditioning unit, responsible for compressing refrigerant and facilitating the heat transfer process that cools your home. When the compressor goes out, it can have significant consequences for your AC unit’s performance, energy efficiency, and overall lifespan. In this article, we’ll delve into the world of compressors, exploring what happens when they fail, the signs and symptoms to look out for, and the options available for repair or replacement.
What is a Compressor, and How Does it Work?
Before we dive into the consequences of a failed compressor, it’s essential to understand what a compressor is and how it works. The compressor is a critical component of your AC unit, responsible for compressing the refrigerant that flows through the system. This compression process raises the temperature and pressure of the refrigerant, allowing it to transfer heat from the indoor coil to the outdoor coil.
The compressor is typically located in the outdoor unit of your AC system and is driven by an electric motor. As the compressor compresses the refrigerant, it creates a high-pressure, high-temperature gas that is then pumped to the condenser coils. Here, the heat is dissipated to the surrounding air, and the refrigerant is cooled and condensed back into a liquid.
