Some of the Best Gas Furnaces You Can Buy in Carlsbad

If you’re in need of a gas furnace replacement in Carlsbad, our Dave Lennox Signature Collection gas furnaces are all great options. These products are a couple of the quietest gas furnaces you can find and are highly energy efficient.

Let’s begin with energy efficiency. Our Dave Lennox Signature Collection gas furnaces include variable speed motors, which limit energy use by only running fans at full speed when extreme heat is required. Variable speed motors use 66% less energy than single speed motors and can help you save hundreds on yearly utility expenses compared to standard furnaces.

Product details for each Dave Lennox Signature Collection gas furnace model are explained below. If you want to talk with a Banister's Heating & Air Conditioning Services professional about one of our products in Carlsbad, call 575-887-7777 or make an appointment online.
