On mild winter days my furnace runs in short blasts and my home keeps alternating between being too hot and too cold. How can I fix this?
A two-speed or variable-speed furnace is the perfect solution to maintaining a level temperature. Two-speed furnaces can run on a lower speed up to 90% of the time. This means they operate more quietly and run for longer periods of time than a single-speed furnace. Longer operating periods mean fewer on/off cycles and much smaller temperature swings. When your system’s fan runs for longer periods of time it prevents air “stratification” (when warm air rises to the ceiling and cold air settles on the floor). You get more consistent, even heat throughout your home. Variable-capacity furnaces (VCF) provide the ultimate combination of comfort, efficiency, and performance. In addition to the benefits of a two-speed furnace, a VCF offers “smart” motors that automatically adjust the volume and speed of air to provide the most efficient heating or cooling for your home – no matter how mild or cold the weather. VCFs offer added electrical efficiency as well because the smart fan motors use less
