Heating and Cooling Efficiency Ratings Explained

In your quest to find the ideal heating or cooling system, you will encounter several important industry-standard efficiency ratings. The higher efficiency your product, the lower your long-term energy costs


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


AFUE (Annual Fuel Utilization Efficiency) is the standard measurement of efficiency for gas fired furnaces and boilers. Given in percentages, this number tells you how much of your fuel is

Hybrid Systems

HSPF (Heating Seasonal Performance Factor) is the efficiency measurement used to gauge the efficiency of the heating mode of heat pumps. The higher the number, the greater the efficiency and

Matching Your System for Optimum Efficiency

One additional factor that affects the efficiency of your air conditioning or heat pump system is your indoor coil. If your condensing unit is not matched with the proper indoor
