Furnace Basics

The four main components of your furnace are:

Burner: The burner is the heart of the furnace, where fuel (usually natural gas, propane, or oil) is mixed with air and ignited to produce heat. This process is crucial for generating the heat that will be distributed throughout your home. The burner must operate efficiently to ensure optimal combustion and energy use.

Heat Exchanger: The heat exchanger is responsible for transferring the heat generated by the burner to the air that circulates through your home. As the burner heats up the exchanger, air from your home's return ducts blows over it, absorbing the heat. This heated air is then pushed through the ductwork and into the living spaces, ensuring your home remains warm and comfortable.

Blower Motor and Fan: The blower motor powers the fan that circulates air through the furnace and the duct system. After the air is heated by the heat exchanger, the blower fan pushes it into the supply ducts, distributing it evenly throughout your home. The blower motor and fan are essential for maintaining consistent airflow and temperature in all rooms.

Thermostat: The thermostat is the control center of your furnace system. It monitors the indoor temperature and signals the furnace to turn on or off to maintain the desired temperature set by the user. Modern thermostats often come with programmable features, allowing you to set heating schedules and improve energy efficiency, ensuring comfort while minimizing energy consumption.
