Gas Furnaces

Residential Gas Furnaces

One of the first things to consider when purchasing a gas furnace is its efficiency. This is indicated by the Annual Fuel Utilization Efficiency rating or AFUE. We offer a variety of highly efficient gas furnaces, ranging from 80% to 95% efficiency. We also offer variable-speed, two-stage and three-stage furnaces, which can greatly increase your comfort level.


Why 2-3 stage gas furnace?
As with all of the 2-stage or multi stage products the gas furnace does not need 100% of the heating most of the time. So the furnace runs in the first stages and only goes to full stage when needed, therefore increasing gas efficiency.

Why duel fuel?
Duel fuel is like a hybrid car if you will, a property with gas furnace(s) as its primary heat source has the available option of installing a heat pump instead of an a/c outside to create 2 fuel sources. This is a very efficient option and gives the property owner the opportunity to cycle between gas furnace and heat pump heat types. Go green and install a duel fuel system for the best of both worlds!

Why Variable Speed?
A normal system cycles on and off at the same speed, the variable speed indoor units start at half speed and give the opportunity for the coil to get ice cold and then ramp up to 1/2 speed and finally to full speed if needed. There is a time delay between each speed. The benefits are more even temperatures and up to 3-4 times more humidity removal in cooling mode than a single speed unit. Variable speed gives you quit, efficient comfort.
