Some of the Best Gas Furnaces You Can Buy in Corpus Christi

If you’re looking for a gas furnace replacement in Corpus Christi, our Dave Lennox Signature Collection gas furnaces are all great options. These systems are a couple of the quietest gas furnaces you can find and are extremely energy efficient.

Let’s start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which conserve energy by only operating fans at full speed when a large change in heat is required. Variable speed motors use 2/3 less energy than single speed motors and can help you save hundreds on your annual utility bills compared to other furnaces.
