Quiet Comfort
Homeowners often prefer gas furnaces that operate quietly and efficiently. The DesertShield brand DSM9C80 Two-Stage, Multi-Speed Gas Furnace is designed with noise reduction in mind.

Energy Efficiency
Energy efficiency translates to cost savings. The efficiency of a gas furnace is primarily determined by its AFUE rating (Annual Fuel Utilization Efficiency), which indicates the percentage of each dollar spent on natural gas that is used to heat your home, and the type of blower used in the furnace.
