Part of HVAC System Part 1

Understanding the parts of the HVAC system can help you maintain it properly and make finding problems easier. Here are some of the main elements of your HVAC system.

Heat Exchanger

A heat exchanger is the part of your furnace that absorbs heat and warms cool air. It contains stainless steel with a temperature-resistant thermostat to prevent cracks and other damage. Problems with heat exchangers can lead to carbon monoxide leaks, which can be dangerous, so you should have the system inspected by a professional at least once per year.

Blower Motor

When the air in your heat exchanger reaches a preset temperature, an blower motor powers a fan that forces the warm air into the ductwork, through the air register, and into all rooms in your home. A variable speed blower motor can run at different speeds to precisely control the airflow around the house.

Combustion Chamber

A combustion chamber is also called a burner. For a gas furnace, the heating process starts when a small amount of air and gas mixture enters the combustion chamber. Then a glow stick or pilot light ignites the mixture, and it burns in a controlled fire as more gas and air movement into the burner. Only older furnaces have pilot lights because they use more gas than a glow stick. Also, they can release carbon monoxide if they go out, which causes a safety hazard.
