A heating and air conditioning company with more than two decades of experience itemizes a heat pump buyer’s guide and checklist for residents in Lemay and neighboring towns.

About Heat Pumps

In terms of replacing a furnace or a standard heating and cooling system, heat pumps afford low operating costs. All year round, heat pumps condition cool and warm air. Designed for energy efficiency and comfort, numerous features attribute to the quality of a heat pump.

Heat Pump Energy efficiency + Performance

The U.S. Department of Energy (DOE) establishes benchmarks for various heating and cooling systems, based on lowest energy consumption. These are measured and featured on all heat pumps based on the seasonal energy efficiency ratio (SEER).

and HSPF (Heating Seasonal Performance Factor).


FYI The ENERGY STAR (R) label identifies which heat pumps comply with the DOE’s energy efficiency standard.

Compare heat pumps based on the seasonal energy efficiency ratio (SEER). The higher the number, the less energy it consumes to emit cool air. Eighteen SEER is currently an optimal benchmark to shop for when buying a heat pump.

Because the DOE’s minimum energy conservation standard for heat pumps continues to change, always check with a heating contractor or the DOE website for the latest SEER standard.

On the warmth mode, heat pumps generate heat at a high efficiency and performance level, measured according to its HSPF (Heating Seasonal Performance Factor).


Demand defrost control is another feature we recommend to those looking to buy a heat pump. Because the feature manages defrosting, it affects how often the supplementary heat pump consumes energy.” reveals a certified heat pump contractor of Lemay.

Type of Refrigerants

Another vital feature to include on the shopping list is the type of refrigerant a heat pump uses. Certain refrigerants, such as R-410A improve compressors and heat pumps’ overall resilience to outdoor extremities. Heat pumps, using refrigerant, R22 release chlorine into the atmosphere and abbreviate a heat pump’s lifecycle. (These systems are being phased out by the DOE over the next two years.


The parts replacement warranty happens to be another vital shopping criteria to compare on a heat pump.

In general, heat pumps and compressors accompany separate warranties. Prior to buying a heat pump, evaluate the parts and replacement warranty to comparable priced models.

Noise Factor

Some heat pumps operate quietly, designed in foam to muffle noise. Because noise factor is hard to compare, consult a heating and cooling contractor who specializes in heat pump installations to assess noise factor.
