Some of the Best Gas Furnaces You Can Buy in Richardson

Top-of-the-line Dave Lennox Signature® Collection gas furnaces are some of the best. They’re also some of the quietest operating systems you can buy and offer efficient heating for your Richardson area home.

Our Dave Lennox Signature Collection gas furnaces boast variable speed motors, which enable more comfort than older 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 could save your family a substantial amount on your energy bills.
