After product safety and durability, most new furnace buyers are concerned about energy efficiency. A furnace’s efficiency can primarily be determined by two factors: its AFUE rating (Annual Fuel Utilization Efficiency), which indicates what percentage of each dollar of natural gas purchased is actually used to heat your home; and the type of blower used in the furnace. A variable-speed blower makes this furnace even more efficient. The low constant fan setting can use as little energy as that needed to run a 75-watt light bulb. As the furnace runs in low-heat capacity, the unity is able to maintain even warmth throughout the house, without high-heat surges.

Nobody likes being jolted from a deep sleep by a noisy furnace surging on. You can say goodbye to those rude awakenings. Because the furnace operates on low capacity 90% of the time, it produces just 25% of the normal high-fire and circulating blower sound. And to make our unit as quiet as possible, we fully insulate the furnace cabinet to reduce sound even further.
