How a Furnace Works

Whenever there’s an issue with your home’s heating, finding the best solution starts with having the right information at your fingertips. That’s why understanding the basics of how your furnace works makes a world of a difference.

In most heating systems there are 5 key components. The thermostat, the burners, the heat exchanger, the blower motor, and the home ductwork.

Your thermostat measures the temperature of the air in your home. Inside the thermostat, there’s a gauge that tells the furnace to turn on or off depending on the temperature you’ve set.

When you raise the temperature setting and the signal from the thermostat is received, fuel is sent to the burners in your furnace and it’s ignited. Once all the furnace burners are lit, they heat up your heat exchanger.

A blower then circulates air over the heat exchanger. The air is sucked in through the air returns located throughout the house, pushed over and around the heat exchanger, warmed, and then sent back out through a network of forced air ducts throughout the house referred to as registers.

It’s important to keep in mind your furnace works all year round. It heats your home during the cold months and works with your air conditioner to help keep things cool during the summer months, so regularly scheduled maintenance is crucial to helping ensure your home feels comfortable all year round.
