Some of the Best Gas Furnaces You Can Buy in Alice

If you’re looking for a gas furnace replacement in Southern Texas, our Dave Lennox Signature Collection gas furnaces are all great options. These models are a couple of the quietest gas furnaces available and are very energy efficient.

We’ll start 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 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 your annual utility bills compared to standard furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are explained below. To talk with a Rescue Heating & Air staff member about one of our products in Southern Texas, call 361-265-4371 or make an appointment online.
