Heat pumps use less energy to heat and cool than traditional heating, ventilation and air conditioning systems. New technology, such as variable speed motors and two-stage compressors, makes them even more efficient. They also better regulate humidity, an important comfort factor in the humid climate of Dallas, Texas. Reducing energy usage lowers utility bills and saves money. A licensed HVAC professional can help you select a heat pump appropriate for your needs.

How Heat Pumps Work

Heat pumps operate on the same principles of refrigeration as standard HVAC systems. However, instead of using electricity to generate conditioned air, heat pumps move heat energy from one place to another. During the winter, heat energy is extracted from the ground, water or air and moved inside. During the summer, heat is extracted from the indoor air and routed outside. Flipping a switch reverses the direction of refrigerant.

Heat Pump Energy Efficiency

Heat pumps are rated for both cooling and heating efficiencies. Seasonal energy efficiency ratios define air conditioning efficiency, and the heating seasonal performance factor describes heating efficiency. In the southern U.S., SEER values must be at least 14. Highly efficient units have SEER ratings as high as 20. Efficient HSPFs range between 8 and 10. The higher the SEER or HSPF, the more efficient the unit.

Many heat pumps now offer multi-stage technology, which increases energy efficiency. Unlike traditional single-stage compressors that run at full speed and then shut off, 2-stage compressors operate at a lower speed for lighter cooling loads. When temperatures rise, the higher speed kicks in to maintain comfort. Variable speed motors enhance this efficiency by automatically adjusting blower speed to match demand, running at just enough speed to keep you comfortable. This technology saves energy and extends equipment life.
