Heat Exchanger

What is a heat exchanger?

A heat exchanger is a metal component of a furnace made of tubes or coils that are used to heat your home. Hot gases are sent through these tubes while the fan blows air over them. This heats the air and then sends it throughout the home while keeping it seperate from toxic gases.

Where is it located?

The heat exchanger is located inside your furnace behind the front access panel near the burners.

Maintenance Tips

  • Check temperature, pressure levels and for any leaks weekly
  • Check PH and chemical levels for fouling every 3 months
  • Lubricate motor bearings annually
  • Clean the plates and tubes annually
  • Replace gaskets and perform pressure testing every 3 years

    • Lifespan

    The lifespan of a heat exchanger is 15 - 20 years.
