Over time, these small leaks can leave your compressor with a lack of adequate lubrication, resulting in excess heat that will cause your compressor to fail.Īnother condition that can cause your compressor to fail is a blocked expansion valve. Similar to motor oil in a vehicle, lubricating oil in a compressor will often work its way out of the small gaps or cracks in the body of the compressor. One common cause of compressor burn-out is the loss of lubricating oil on the moving parts of the compressor. However, there are a few conditions that can cause your compressor to burn out. Given their high-intensity job, compressors are generally built quite tough. This process continues until the thermostat senses that your home has reached the desired temperature and shuts the system off. When the pressure is low enough, the refrigerant moves inside your home, replacing the higher-pressure refrigerant that has been busy removing heat from your home. As air moves over the condenser coils, the pressure and temperature of the refrigerant begin to drop, which eventually causes the refrigerant to turn back into a liquid. Then, because of this difference in pressure, the refrigerant, as a gas, moves to the condenser coils. When this happens, thanks to thermodynamics, the heat is expelled from the refrigerant and into the outdoor air. Sitting outside your home, the compressor’s job is to increase the pressure of the refrigerant to a point where its temperature is higher than the surrounding air. The way the temperature in the refrigerant is changed is by changing the pressure of the refrigerant to a specific level. This refrigerant is a substance that changes from a liquid to a gas at a predictable temperature. In an air conditioner, the primary way that heat is removed from your home is through the refrigerant. If you think you might be experiencing problems with your compressor, here is some basic information on what you can expect throughout the diagnostics process and replacement process. Without a compressor, the rest of the cooling process can’t happen. Though there are several components in a central air conditioner, one of the most important is the compressor.
After all, the only thing you have to do is set your thermostat to the desired temperature and, before you know it, there is cool and refreshing air flowing through your vents. Just how it accomplishes that, though, may be a bit of a mystery. You know that your air conditioner keeps your home cool and comfortable all summer long.
