Efficiency Info
The efficiency of a furnace is measured by the Department of Energy's "Annual Fuel Utilization Efficiency" (AFUE). All furnaces are rated by how efficient they are at heating air, and losing as little as possible.
Utilizing a more energy efficient heating unit will increase your cost savings. Our knowledgeable technicians can provide important information that will help you to increase the energy efficiency of your HVAC system.
Here's a more detailed explanation from the DOE (Department of Energy) website.
