Gas Furnace Basics
A gas furnace is a popular type of heating system in many homes. It uses natural gas or propane, burning it via a burner and producing warm air to heat your home. The air passes through the air filter, then the heat exchanger, and becomes hot air. This hot air is pushed by the blower fan throughout your house via ductwork or plenum.
The gas valve is a major component of the system. It controls when gas gets to the burners and when it stops. Safety features such as limit switches and pressure sensors avoid fires from getting out of control. An inducer motor kicks off the combustion process by removing any hazardous gases before sparking.
When buying a gas furnace, think about the efficiency and size of your house. Moreover, always get a certified HVAC technician to install it. This stops carbon monoxide leaks.
To keep your gas furnace in good shape, inspect the components regularly for dust and debris. Replace the furnace filter at least every month during the heating season, or every three months when used lightly. Plus, book regular maintenance and clean-up with a reliable HVAC technician to keep it running smoothly.
