Air Source Heat Pump

New high-efficiency heat pumps (ASHP) save significant amounts of energy in heating and cooling your home. There have been significant improvements made in the design of ASHPs for both energy efficiency and comfort. ASHPs have two efficiency ratings: Seasonal Energy Efficiency Ratio (SEER) for the cooling mode and Heating Seasonal Performance Factor (HSPF) for the heating mode. With both ratings, higher SEER and HSPF numbers equate to higher levels of energy efficiency. ENERGY STAR® labeling requires new ASHPs to have a SEER of 14.5 or greater and a HSPF of 8.2 or greater.

Proper selection, sizing and installation of new ASHPs are essential to achieving the greatest savings from the replacement. It is important to first improve the overall energy efficiency of your home by air sealing the home to reduce hot air and humidity infiltration, insulating walls, ceilings and floors, and sealing any ductwork located in attics and crawl spaces. These improvements will probably allow the home to use a smaller ASHP, saving money on the initial cost of the unit and on your utility bills for years to come. Remember: an oversized ASHP wastes energy and costs money. A trained HVAC contractor should recalculate your heating and cooling needs after the home efficiency upgrades to determine the proper size equipment for your home.
