Comparing Forced-Air and Central Air HVAC: Key Differences
Forced-air and central-air HVAC systems both heat and cool homes, but in different ways. Forced-air systems use a furnace and a fan to blow heated air through ducts into rooms. Central air systems, usually part of forced-air systems, specifically cool air and send it through the same ducts. The main difference is that forced-air systems can only heat, while central-air systems can only cool. Often, central air is added to forced-air systems to have both heating and cooling from one system.
