Some of the Best Gas Furnaces You Can Buy in Gresham

Our Dave Lennox Signature® Collection gas furnaces are some of the best you can find. They also have some of the quietest heating around and provide efficient heating for your Portland area home.

Our two Dave Lennox Signature Collection gas furnaces boast variable speed motors, which help produce more comfort than typical single speed furnaces. In a variable speed furnace, blower fans start up slowly and only operate at full speed when extreme heat is demanded. These furnaces could save your family a substantial amount on your energy bills.

Find out more about our Dave Lennox Signature Collection furnaces below. When you’re ready to take the next step in your gas furnace replacement process, give Honke Heating & AC in Gresham a call at 503-376-8806 or schedule your appointment online.
