Gas Furnaces

Bottom Swoop


There are four types of furnaces, including:

  • Natural gas & propane furnaces: These use natural gas or propane ignited within the burner to generate heated air that is then blown via the blower motor through the ductwork in your home.
  • Oil furnaces: These use heating oil as fuel in a process similar to gas furnaces.
  • Electric furnaces: These use electric heating elements to warm the air, which is then blown through the ducts via a blower motor.

Frequently Asked Questions

What’s the typical life span of a gas furnace?

With proper maintenance and prompt repairs, you can expect a serviceable life span of 15 to 20 years from modern gas furnaces.


When should I replace, rather than repair, my furnace?

We recommend replacement when the unit is near the end of its estimated life span or if any repair exceeds 50% of the replacement cost. Similarly, you may want to replace a unit that requires increasingly frequent or costly repairs.


Why is my furnace making strange noises?

Strange noises, including banging, grinding, and screeching, can be caused by worn-out belts, defective fans, loose components, leaky ductwork, and many other issues that a licensed and insured HVAC technician can investigate and diagnose.


Can a cracked heat exchanger be repaired?

No, it’s not possible to guarantee any crack is entirely sealed once the heat exchanger is damaged. As a result, any repair may allow toxic, potentially fatal carbon monoxide emissions to leak into the home.
