How Does A Home Comfort System Work?

Understanding how a home comfort system works starts with knowing what it is and what it consists of. A home comfort system, also called an HVAC system or a split system, has four parts:

Indoor unit, such as a furnace or air handler
Outdoor unit, either an air conditioner or a heat pump
Thermostat
Indoor air quality component, like a filtration system or humidity control product
