Understanding the various parts of an HVAC system will help customers maintain them properly and fix small problems before they become big ones. The most important parts of a system are the blower motor, condenser, combustion chamber, evaporator, heat exchanger, and thermostat; they’re discussed below.
The Heat Exchanger
The heat exchanger is in the furnace housing, and it warms cooled air when the thermostat switches the furnace on. All furnaces have them, even electric ones, and these important parts are resistant to damage. However, when they do become damaged, they may cause dangerous carbon monoxide leaks. Therefore, it’s important to have the entire system inspected at least once a year.
The Blower Motor
After the heat exchanger’s air reaches a predetermined temperature, the blower motor powers the fan that moves warm air through the ductwork and into the home. Combustion ceases before the motor stops operating, and all the warm air in the heat exchanger and the ductwork will get into the home before the motor stops working and waits for another heating cycle.
The Combustion Chamber
Oxygen is a necessary component of combustion, and the furnace mixes air and fuel inside a combustion chamber. On gas furnaces, the heating cycle is initiated when the air and gas mixture goes into the combustion chamber.
The Compressor or Condenser Coil
These components are part of the heat pump or air conditioner, and they’re typically installed outside the home. A condenser cools the home by removing heat and releasing it outdoors. Simultaneously, a fan moves air over the compressor to cool refrigerant and disperse heat. From there, the HVAC Bristol CT moves the refrigerant through copper or aluminum tubing to the evaporator coil.
The Evaporator Coil
This is a crucial part of the system that’s typically inside the air handler. The system moves refrigerant through a series of expansion valves or nozzles, which spray it and make it evaporate faster. With this action, heat is absorbed, and the home’s temperature is lowered.
Thermostats have temperature sensors that determine when the HVAC Bristol CT turns on and off, and they include user controls as well. The thermostat should be installed near the center of the home, away from drafty or stuffy areas.
