Air handlers and furnaces aren't often used in the same home in Dayton. If you use a furnace, you most likely won’t need to spend time thinking about an air handler.
Air handlers are usually used with heat pumps and deliver airflow throughout your home. Some models also offer extra heating and cooling parts to support the heat pump.
A furnace heats in a different manner by sending hot air into your vents, which send it around your residence. Because furnaces have combustion chambers to make heated air, they don't have some of the components you'll spot in a regular air handler.
