Some of the Best Gas Furnaces You Can Buy in Keokuk

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 provide efficient heating for your Keokuk area home.

Our two Dave Lennox Signature Collection gas furnaces boast variable speed motors, which allow more comfort than traditional single speed furnaces. Variable speed furnaces’ blower fans start up slowly and only operate at maximum speed when a much higher temperature is demanded. These furnaces may save your family hundreds on utility expenses.
