Terms like SEER, AFUE and HSPF are commonly used to describe efficiency ratings in the indoor weather industry. Offering indoor weather equipment that ranges from the minimum industry requirements to the world's most totally energy efficient, your indoor weather expert can help you choose the indoor weather equipment that's right for you. AFUE- (Annual Fuel Utilization Efficiency) is the standard measurement of efficiency for gas and oil-fired furnaces. Given in percentages, this number tells you how much of your fuel is used to heat your home and how much fuel is simply wasted. The higher the AFUE rating, the greater the efficiency. SEER- (Seasonal Energy Efficiency Ratio) is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER number, the greater the efficiency, which translates into greater energy savings. Today, U.S. regulatory agencies require all new models to have a 10.0 SEER rating HSPF- (Heating Seasonal Performance Factor) is the efficiency measurement used to gauge the efficiency of the heating mode of heat pumps. Again, the higher the number, the greater the efficiency. Today's models are required to have a 6.8 HSPF. Bels- Bels-the rating system by which sound is measured. The bels scale is a logarithmic scale like the Richter scale...even a small difference in rating can mean a significant difference in actual sound. The higher the number, the greater the noise level. A diesel truck 10 feet away is rated at 9.2 bels. The sound of a refrigerator running is rated at 7.0 bels.
