Forced air heating is a type of HVAC system used to heat a home. It is a central heating system that uses air as a transfer medium for heat. The system generates heat through natural gas, propane, or electricity. In a gas furnace, a heat exchanger is warmed up by gas ignition and moving air absorbs heat from the exchanger. In an electric furnace, moving air absorbs heat from high-resistance wires. With both systems, hot air is then pushed out into your home through ductwork and vents. The ducts can be concealed in crawlspaces, attics, or walls. The air volume within the house is continually cycled through the system via return air ducts.
Forced air heating systems are energy-efficient and can be controlled by a single thermostat. They can supply heat to the entire house by fan-forced air through ductwork. Forced air heating is popular for its energy efficiency, heating time, easy installation, reliability, high indoor air quality, and compatibility with smart devices. However, it requires regular maintenance and produces noise.
