Air handlers and furnaces aren't often used in the same home in La Porte. If you use a furnace, you probably shouldn’t need to spend time thinking about an air handler.
Air handlers are frequently paired with heat pumps and manage airflow throughout your residence. Some models also provide secondary heating and cooling components to support the heat pump.
A furnace runs in a different way by blowing heated air into your vents, which circulate it around your house. Since furnaces have combustion chambers to create heated air, they don't need some of the components you'll see in a normal air handler.
