For most homeowners, air conditioning or heating is a necessity.
Furnace efficiency is usually calculated using a laboratory procedure that measures an appliance’s “annual fuel utilization efficiency,” or AFUE.HVAC systems move heat or cold air out of the room when you need.Essentially, your system acts as a transportation system for cold and hot air outside and inside the home. Sadly, this illustration comes from the web site of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). In Europe, where furnaces are almost unheard of, most homes are heated by a boiler that distributes heat through hot-water pipes. Furnaces should be installed in your basement or a mechanical room near the center of your house — not in a vented attic, vented crawl space, or garage.
