HVAC Components - Know Your System!

Central HVAC systems are often called “split” systems because some of the components are installed inside the home and some of the components are installed outside a home. Inside your home, usually installed in the basement, attic, or a closet, you’ll find the furnace (oil, gas, or electric) and the evaporator portion of the air-conditioner. You’ll also find the blower (sometimes called an air handler), which serves both the furnace and the air-conditioner. Attached to the blower are ducts, which are tubes acting as pathways to deliver heated or cooled air to various rooms in the house.

If your HVAC system is a heat pump, it won’t have a separate furnace. A heat pump works like a regular air-conditioner in the summer, then essentially works in reverse in the winter, serving both cooling and heating purposes. A heat-pump system will still have indoor and outdoor components.

Outside the house you’ll find the compressor and condenser components of the central air-conditioner (or heat pump), which are mounted in a metal cabinet with a large fan.

One alternative to a split-system is called a “packaged” system, in which all components are installed in a single unit outside the home, with ducts entering through the wall of the home. These units may be preferable for a homeowner who doesn’t want to waste space on the interior of their home with heating and cooling equipment.

Not often addressed in most HVAC installations is the “V” – ventilation. Most homes rely on infiltration, or air that seeps in through gaps and cracks in the home’s shell, for limited fresh air. Indoor air quality (IAQ) is increasingly implicated as a big factor in human health problems, mechanical ventilation systems are becoming more commonplace.
