When dealing with heating, cooling and ventilation systems, designed to keep you comfortable and breathing healthy air at home here in Northern Indiana, you'll come across the following rating systems for HVAC products. It pays to be an informed consumer, so here’s an outline of what the ratings and certifications mean to you:

Furnaces are given an AFUE (Annual Fuel Utilization Efficiency) rating, measuring their seasonal fuel efficiency. The rating tells you the amount of heat produced for each dollar you spend on fuel. (The AFUE doesn’t rate the amount of electricity used – just the unit's fuel efficiency.) The higher the rating percentage, the better. A 90 percent rating means that the unit will convert 90 percent of its fuel to heat and the other 10 percent goes out the chimney. A minimum 90 percent efficiency for gas furnaces and 85 percent for oil-powered units is required for products to earn the US government’s blessing with the Energy Star label. Energy Star is a joint program of the EPA (Environmental Protection Agency) and DOE (Department of Energy).

Cooling equipment is given a SEER (Seasonal Energy Efficiency Ratio) rating, which expresses the cooling output (in Btus or British thermal units) during an average summer divided by the electric energy input (in watt-hours) during the season. Higher ratings are better, meaning more energy efficient air conditioners/systems which will cost less to operate. SEERs of 14 or greater meet Energy Star’s qualifications.
