Heating technology often plays a large role in your indoor comfort level and fuel bill during the cold months of the year. Daikin furnaces provide warm, money-saving comfort. With options such as modulating, variable, and multispeed equipment, Daikin has an enhanced solution for any home design. The interior, tubular heat exchanger, the core of a Daikin furnace, is constructed of stainless steel, and these state-of-the-art indoor systems can be easily paired with one of the Daikin FIT side discharge condensers. Furnace efficiency is designated by an AFUE (Annual Fuel Utilization Efficiency) rating. This score is used to rate furnace efficiencies by dividing the ratio of heat output by heat input. This measurement describes how well fuel, gas, or oil is consumed to produce heat by a furnace. As the AFUE rate increases, the efficiency of your furnace also increases, helping to lower your fuel costs. Every Daikin gas furnace is engineered to earn a high AFUE rating. But these furnaces not only do a great job of home heating during the cold months of the year, but the internal fan is also used to assist the air conditioning system in circulating cooled air when the outdoor temperatures increase. A Daikin furnace with a two-stage or variable-speed fan allows your system to provide continuous airflow, which means consistent indoor comfort for you and your family.
