Gas Furnace

A gas furnace uses gas as a fuel source to produce heat, which is then re-distributed throughout your home.

What is a Gas Furnace?

A gas furnace is a type of heating system that utilizes natural gas or propane to generate warm air. This air is then pushed through ductwork and distributed throughout the entire home, ensuring even temperatures in each room. Gas furnaces are energy efficient, cost-effective and easy to operate; they produce more heat for less money than other types of central heating systems. 

How does a gas furnace work?

Gas furnaces use an ignition source (such as electric spark) to ignite the gas as it enters the burner assembly. This ignites the mixture of fuel and air, creating combustion which produces heat. The heat is then transferred into metal chambers where it radiates from hot surfaces within the unit before being blown into the home’s air distribution system. The blower fan within the furnace then distributes the warm air through the ductwork until all rooms of the home are evenly heated. Watch a video to learn how a furnace, heat pump, and AC work together.

Benefits of a gas furnace

Gas furnaces are one of the most efficient and cost-effective heating systems available today. Additionally, gas furnaces have longer lifespans than other types of heaters, typically lasting anywhere from 20-30 years depending on usage and maintenance. Other benefits include: 

  • Higher efficiency and Lower energy costs: Gas furnaces can be up to 97% efficient. With natural gas generally cheaper than electricity in most parts of the country, this results  in lower heating bills.
  • Maximum Comfort: Gas furnaces can generate warm air at higher temperatures, providing consistent heating comfort throughout the season, especially in colder climates.
  • Clean burning: Natural gas is a clean energy source, producing fewer emissions than other sources of fuel 
  • Healthier air: Gas furnaces don’t require the same type of air filters that electric heaters do, meaning your indoor air quality stays fresher and healthier.
