A central air conditioner cools in a single location, then distributes that cooled air throughout the house using a series of fans and ducts. There are also non-furnace home heating solutions, such as heat pumps and steam heat boilers, which interact with HVAC systems in ways similar to furnaces. You can close and confirm your location on the form or view all dealers in your area. During warm seasons … Ductless will never work properly if the system is the wrong size, the wall penetration isn’t sealed correctly, or the sensitive electronics are mishandled. The most common type of furnace is a gas-powered central air system, which heats air in a one area and then distributes it throughout the home via ductwork and vents. In electric furnaces, this is simply a matter of the exposure of the heating elements to the open air. Combustion gases are generated by the burners in your furnace and passed through a heat exchanger. Dealers and Distributors, Find a Dealer by Central air and heating systems use a series of ducts to circulate cool air or heat throughout the home. When the temperature in the house drops below the thermostat setting for heat, the thermostat sends two signals: one to the furnace to begin a heating cycle, and another to the blower motor to activate the HVAC fan.
