During the summer, this cycle reverses. The Heat Pump removes heat from the indoor air, providing cool air just like a conventional air conditioner. The best of today's heat pumps are more than twice as energy efficient as they were 10 years ago. The rest of their heat is wasted through the chimney. Availability Energy efficient constant-speed, variable speed and geothermal heat pumps are readily available through qualified contractors throughout New Jersey.
Proper installation is the key to maximum comfort and energy performance.
Most heat pump systems cost less than installing a high efficiency fossil fuel heating system and central air conditioner, because the heat pump is both a heating system and air conditioner in one. Because of their special features, variable speed and geothermal heat pumps may cost more. Many electric utilities offer attractive rebates and low interest loans to help customers purchase high efficiency heat pump systems. Cost of Operation Because of their unmatched energy efficiency, geothermal heat pumps have the lowest operating costs of any heating and cooling system. Variable speed systems are the next most economical, followed by conventional constant speed units.
