Some of the Best Gas Furnaces You Can Buy in Columbia

Innovative Dave Lennox Signature® Collection gas furnaces are some of the best of the best. They’re also some of the quietest operating systems you can buy and produce efficient heating for your Columbia area home.

Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which allow more comfort than older single speed furnaces. With a variable speed furnace, blower fans start up slowly and only operate at their highest speed when a much higher temperature is demanded. These furnaces can save your family a significant amount on utility bills.
