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.
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.
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.
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.
