How does my furnace work?

At Distinct Heating & Cooling, our technicians enjoy educating people about how their home heating system functions. The reason why we want to educate people is to help them identify when there are potential problems with the system. This could help you avoid costly repairs.

Your heating system has many components that work together to provide optimal comfort and keep you warm. To help you better understand how the system works, let’s start by reviewing the four basic components found in your furnace.

  1. Thermostat – The thermostat is a heat-sensitive switch used to regulate the temperature of your home based upon your preferred comfort level.
  2. Furnace – The furnace is the source of the warm air used to heat the home and maintain comfort levels.
  3. Blowers, Ducts, and Vents – Each of these components are responsible for moving and distrusting the heated air throughout your home.
  4. The Flue – This is the exhaust duct connected to the furnace and extends to the outside of the home. This vents the harmful gaseous by-products of your furnace out of the home.

All of these components working together are called the heating system. The heating cycle begins when the thermostat determines the temperature within the home has fallen below the desired one you established, which is call the set point. The thermostat responds to the change in temperature by sending a signal to the furnace to turn on. Essentially, your thermostat is telling the furnace to “wake up.”

The furnace kicks in and turns on the natural gas and ignites it. The fire creates heat and is used to heat up a series of metal tubes within the unit that are called the heat exchanger. As the fire is burning, any harmful gaseous by-products are vented safely outdoors through the flue.

Once the heat exchanger has reached a certain temperature, the blower motor engages and turns on its fan. The fan blows air over the heat exchanger and into the ducts. Eventually, the warm air is blown out of the register vents within the rooms of your home.

After the furnace has ran for a period and the temperature reaches the set point, the thermostat sends another signal to the finance to shut off. This is the end of the heat cycle.

A Quick Tip about Aging Heating Systems

As your heating system ages, it can lose its efficiency or stop working altogether. A furnace failure, especially during the middle of the winter in Calgary could be inconvenient on a cold day, not to mention a serious problem. At Distinct Heating & Cooling, we recommend scheduling our annual 30-point heating system tune-up and maintenance inspection to avoid serious problems and keep your heating system operating at peak performance throughout the winter.
