A central air conditioner cools with an outdoor compressor and condenser coil connected to an indoor furnace fitted with an evaporator coil. 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.

In electric furnaces, this is simply a matter of the exposure of the heating elements to the open air. In gas and oil furnaces, those fuels are released through valves to produce open flames. As the current goes through the coils it creates heat, warming the air. Rooms have a cold air intake vent, which allows cool air to be sucked down into the furnace. Most homes rely on central furnaces to supply heat to all rooms. 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. AC evaporator coil removes heat and humidity in summer. If your house has central air conditioning, cool air probably flows through the same ducts that heat does and is regulated by the same thermostat.

The thermostat detects the moment when the indoor temperature reaches the desired level and sends signals to shut off the furnace and blower motor. Central air and heating systems use a series of ducts to circulate cool air or heat throughout the home. The furnace is one of the most important appliances in the home, yet many people have no idea how it works. There, electric heating elements heat the air, and the blower pushes the warmed air back into rooms through a system of duct work. The furnace’s heating elements receive the signal and activate. Once there, it is heated using natural gas, propane, oil, coal, wood, or electricity. 2.The heat produced passes through a heat exchanger, making it hot. Already a customer?
