Some of the Best Gas Furnaces You Can Buy in the Main Line

If you’re in need of a gas furnace replacement in the Main Line, our Dave Lennox Signature Collection gas furnaces are all great options. These products are two of the quietest gas furnaces available and are extremely energy efficient.

Let’s begin with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which limit energy use by only operating fans at full speed when an extreme change in heat is required. Variable speed motors use 66% less energy than single speed motors and may help your family save hundreds of dollars on utility expenses each year compared to standard furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are provided below. If you want to talk with a O'Brien Heating & Air Conditioning professional about one of our products in the Main Line, call 610-257-7035 or set up an appointment online.
