To prolong the life cycle of HVAC systems, it is important to understand and learn their parts. This way, identifying and fixing issues becomes easier. While HVAC system parts vary depending on the type of unit, below are the 6 main components that you should familiarize yourself with, should you maintain or clean your HVAC system:
1. Heat Exchanger
One of the most essential parts of an HVAC unit is the heat exchanger. This component assists in heating and cooling. It absorbs the heat that’s produced in the combustion chamber and moves it from one place to another. It is crucial for heat exchangers to be inspected and cleaned every 12 months to identify early signs of damage. The smallest issue with this component can lead to serious health issues such as carbon monoxide poisoning.
2. Thermostat
The thermostat serves as the control for regulating and stabilizing temperature in a residential or commercial building. It enables users to set ideal temperatures and conditions. Thermostats should be installed and calibrated correctly to prevent early wear and tear caused by the system running overtime or ineffectively.
3. Combustion Chambers
A combustion chamber, also known as a burner, is responsible for producing heated air that the HVAC system distributes. The heating cycle begins when oxygen and gas mixtures enter the combustion chamber and then a pilot light or glow stick turns on to ignite the mixtures in a controlled manner.
4. Blower Motor
A blower motor is a small but important component of an HVAC system. It is responsible for moving heated or cooled air across the ductworks. Once the heat exchanger warms air according to the desired temperature set from the thermostat, the blower motor powers its fan to blow the air towards the ductworks to distribute across the home or building.
5. Condenser Coil/Compressor
The condenser coil or compressor is responsible for releasing hot air outdoors. It lowers the indoor temperature by siphoning hot air from inside. Using a refrigerant, it allows the air cycle of circulation and filtration to occur. The condenser coil is located outside of the home or building, which makes it prone to accumulation of leaves, dirt, or debris that can affect its system performance. To maintain it in good working condition, regular maintenance and cleaning is required.
6. Evaporator Coil
Similar to the condenser coil, it also absorbs hot air from indoors. However, instead of releasing it outdoors, what it does is it cools that hot air using a refrigerant and then distributes it via air conditioning to lower indoor temperature. Regular maintenance and cleaning are also required to prevent the evaporator from being frozen, or damaged.
