Heat Pump Efficiency HSPF Air Source Heat Pumps, often used in moderate climates to heat and cool a home, are rated by a Heating and Seasonal Performance Factor (HSPF) Heat Pumps use the difference between outdoor and indoor air temperatures to cool and heat your home much like standard air conditioners do. The difference is that Heat Pumps can cycle in both directions and can therefore provide cooling in the summer months and heating in the winter. High efficiency Heat Pumps have a higher Heating and Seasonal Performance Factor (HSPF) and use less energy than conventional models. |
