Non-Energy Benefits of EfficientHeat Pumps
Return to Non-Energy Benefits index
Efficient heat pumps may operate more quietly, be more visually appealing, have better temperature and/or moisture control, and be easier to maintain than minimum efficiency heat pumps.
Efficient heat pumps may operate more quietly than standard (minimum efficiency) heat pumps. Most heat pumps that qualify for the ENERGY STAR label come with "sound blankets" on the compressor to make the outdoor condensing unit quieter.
Efficient heat pumps may be more visually attractive than minimum efficiency heat pumps. Manufacturers of high-efficiency heat pumps tend to put more effort into making the outdoor condensing unit look more attractive (e.g., better cabinet shape and better corner posts and grills).
Some efficient heat pumps may have better control systems that improve the humidity and/or temperature control.
Some efficient heat pumps are easier to maintain than minimum efficiency units. Some high-efficiency heat pumps have ports on the refrigerant tubing coming in and out of the compressor, which make it easier to check the refrigerant charge.
You can obtain additional benefits by having your contractor install the correct size (capacity) of heat pump for your home. Proper sizing helps to reduce humidity and therefore control mold and mildew, and also reduces energy consumption.
