Central air conditioning systems lower the overall heat and humidity in a home. Air conditioning systems have two main components, the indoor evaporator unit and the outdoor condenser. The sealed system uses coolant to transfer heat from indoors outdoors.
The major component of the condenser is the compressor, which pressurizes the refrigerant into a hot liquid. This liquid then flows directly to the condenser and travels through its coil. The heated liquid escapes through the finds of the condenser. When this fluid reaches the end of the coils, it is a lot cooler and a pressurized liquid that flows through the compressor relief valve and leaves the condenser as a mist. This liquid will evaporate into a gas when it leaves the condenser complete and enters the evaporator. As the liquid is evaporated, the heat is drawn out of the air and the area is cooled.
Dirt, debris or dust is a common problem in condenser coils. Bent fins also can occur, which results in less effectiveness. Refrigerant leaks can also happen. All of these problems can be avoided by regular HVAC maintenance visits. These professionals can clean the unit thoroughly and ensure it is running smoothly to save you energy, keep your home cool and best of all, keep you from replacing a system in the long run.
