The Main Parts of Your HVAC System

The HVAC system is one of the essential components of your home. Understanding the main components of your unit makes it easier to find and fix problems, as well as prevent costly breakdowns and keep it running at peak performance after HVAC installation in Braselton, GA. Clark’s Heating and Air discusses more below:

Heat Exchanger

The heat exchanger is a part of the furnace housing. It’s made up of temperature-resistant alloys and strong stainless steel to prevent damage. This component warms cool air and absorbs heat when the thermostat activates the furnace, and heat from combustion increases. Scheduling regular HVAC services is crucial to maintaining the heat exchanger.

Blower Motor

After the air in the heat exchanger attains a suitable temperature, it is forced into the ductwork by a fan powered by the electric blower motor. From the ducts, the air flows through the air registers and into all rooms on the premises. Ensure that you carry out regular HVAC maintenance to keep your blower motor working at peak quality.

Combustion Chamber

The combustion chamber is also known as a burner. It's where the heat is produced and requires oxygen for combustion. The furnace supplies air and gas into the combustion chamber to initiate the heating cycle.


This is part of the HVAC system that is usually installed outdoors. It cools the rooms by releasing heat into the outdoor air. The system compresses and condenses the warm refrigerant gas into a cold liquid as the fan blows over it to cool the refrigerant faster. The cold liquid then travels along the tubes to the evaporator coil.

Evaporator Coil

The coils, along with the refrigerant, help cool the air as it passes through into the rooms. When the liquid refrigerant gets to the expansion valves in the evaporator coil, the valves spray it to transform it from liquid to gas. The process absorbs the heat and lowers the room temperature. If you experience any breakdowns, reach out to Clark’s Heating and Air for HVAC repair services.


The thermostat uses temperature sensors to determine when the hvac system is turned on and off. It also has user controls to help control the room temperature. A programmable thermostat allows you to change the room temperatures automatically based on your routine.Clark’s Heating and Air is a trusted HVAC company that offers quality HVAC solutions.
