Some of the Best Gas Furnaces You Can Buy in Moline Innovative Dave Lennox Signature® Collection gas furnaces are some of the best you can find. They’re also some of the quietest operating systems you can buy and provide efficient heating for your Rock Island County area home. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which enable more comfort than older single speed furnaces. With a variable speed furnace, blower fans start up slowly and only operate at full speed when a much higher temperature is demanded. These furnaces could save your family a substantial amount on your energy bills. Learn about each of our Dave Lennox Signature Collection furnaces and features here.
