How Does a Furnace Work?

Prudent homeowners in Shelby Township know just how important it is to make sure that their HVAC system is functioning properly throughout the year for maximum comfort and safety for the family.

How Does a Furnace Work?

When winter arrives, you don’t want to get left out in the cold because of a malfunctioning furnace. Signs that a furnace isn’t working properly include short running cycles (indicating various equipment problems) and higher gas bills (an inefficient system).

If your furnace doesn’t seem to be working properly or has been making unusual sounds, it is time to call in for furnace repair. Before you arrange for a professional to inspect and repair your heating, ventilation and air conditioning system, it’s a good idea to familiarize yourself with how a furnace works.

Basics of Furnace Operation

After you set your forced air gas furnace’s thermostat, it senses how cold your home is and activates the system whenever the temperature drops below the minimum setting.

A smart thermostat lets you set different programs, such as running the furnace more often over the weekend when everyone is home and less often when the family is away at work and school for much of the day.

The igniter lights the furnace’s combustion chamber burner, which uses a mixture of gas and air to create heat for your home.

Heat rises from a heat exchanger located above the burner. Once the air reaches the designated temperature, your furnace’s blower pushes it through a series of ducts connected to each room in the home.

For the safety of your home and family, the combustion gases are exhausted out of the building through a chimney or flue.

An electric fan is responsible for moving the heated air through your home. While running, the furnace constantly sucks in fresh air into the plenum before moving it through the rest of your home.

As you can see, there are many points in the system that our specialists will need to inspect to make sure everything is working properly. Regular maintenance and cleaning is crucial too. Something as simple as a clogged furnace filter can make the system run inefficiently, wasting gas and money and potentially leading to an equipment breakdown.
