A Duct Heating Coil is a device designed to heat the air flowing through a furnace or air conditioning system. It works by transferring heat from a hot water, steam, electric, or gas source into the air stream in the ductwork of a home’s HVAC system. This heated air can then be used to warm a space quickly and efficiently, reducing energy costs and keeping homes comfortable in cold weather. Duct Heating Coils can provide an excellent source of supplemental heat during cold months while also helping to maintain temperatures year-round.
