Heat Pump Buying Guide

Dec. 17, 2021

Despite the name, heat pumps do a lot more than just heat. They also provide air conditioning and humidity control. During the heating season, a heat pump moves heat from the cool outdoors to your home; then in the cooler months, it moves heat from your house to the warm outdoors. Heat pumps move heat rather than produce it, so they cost much less to heat and cool than other systems such as furnaces and central air conditioning.


Types of heat pumps

There are three main types of heat pumps - air source, split ductless, and geothermal. All heat pump systems should be installed by a professional heating and cooling technician who can determine the right size and the right product for your home and climate. Sunrain all in one heat pump water heater is a very smart design to provide domestic hot water for the house. With all in one type and water tank inside, it is very easy for installation and convenient for users.            


Things to know before you buy

Energy efficiency

The cooling efficiency of air-source and ductless manifold systems is measured by the SEER (Seasonal Energy Efficiency Ratio). The federal minimum is 13 SEER for new residential units in the Northeast, Midwest, Mountain, and Pacific Northwest regions; for the rest of the country, the minimum is 14 SEER.

Heating efficiency for air-source and ductless manifold systems is measured by the HSPF (Heating Seasonal Performance Factor). The minimum federal HSPF rating for all units is 7.7.


In warmer climates, a higher SEER is more important, but in colder climates, a higher HSPF is better. According to the American Council for an Energy-Efficient Economy, you should consider purchasing a heat pump with at least 15 SEER and 8.5 HSPF. The most efficient ENERGY STAR-rated heat pumps are 18 to 27.5 SEER and 8.5 to 12.5 HSPF.

Geothermal heat pumps are rated by EER (energy efficiency ratio) for cooling and COP (coefficient of performance) for heating efficiency. Depending on the type, the federal EER has a minimum value of 17.1 to 21.1 and the COP a minimum value of 3.1 to 4.1.


Generally, the higher the rating, the higher the cost of the system. You can spend thousands of dollars more on a more efficient heat pump. However, depending on where you live, you could save $115 or more per year on your utility bills by replacing your old heating and cooling system with an ENERGY STAR-rated product.

Size is also important. If a heat pump is too small or too large, it won't heat or cool efficiently and will increase your energy bills. Your home may feel uncomfortable. A unit that is too large will cost more upfront and will cycle on and off too many times, shortening its lifespan.


New heat pumps operate efficiently in many parts of the country, especially where temperatures do not fluctuate much and heating and cooling needs are moderate. However, if you live in an area with extremely low temperatures, below 10°F to 25°F depending on the size of the system, you will need an auxiliary heating system.


Work with a heating and cooling professional who should use the Air Conditioning Contractors of America (ACCA) Manual J calculation to determine the proper size. This calculation takes into account your home's foundation, wall thickness, insulation values, windows, air filtration, and more.
