Some of the Best Gas Furnaces You Can Buy in New Castle

If you’re in need of a gas furnace replacement in New Castle, our Dave Lennox Signature Collection gas furnaces are all great options. These models are a couple of the quietest gas furnaces available and are highly energy efficient.

Let’s start 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 a large change in heat is required. Variable speed motors use two-thirds less energy than single speed motors and can help you save hundreds on utility expenses each year compared to other furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are explained below. If you’d like to talk with a Central Heating & Plumbing professional about one of our products in New Castle, call 724-401-1843 or schedule an appointment online.
