Air handlers and furnaces aren't often found side by side in Kingston. If you use a furnace, you likely don't need to spend time thinking about an air handler.
Air handlers are frequently used with heat pumps and deliver airflow across your residence. Some models also offer extra heating and cooling parts to assist the heat pump.
A furnace works in a different way by pushing hot air into your vents, which send it across your home. Because furnaces rely on combustion chambers to make heated air, they don't have some of the components you'll find in a normal air handler.
