Sales of air-source heat pumps used to be concentrated primarily in the Southern U.S., but that is changing as consumers become more aware of their energy-saving capabilities. In fact, in many markets, it may be more cost-effective to use an air-source heat pump for the majority of a homeowner’s heating and cooling needs.
The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well.
Comfort and Higher Efficiencies are Hallmarks of Commercial Products

It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.
Pair to Develop, Manufacture Geothermal and Water-Source Heat Pumps
November 25, 2013
Carrier Corp. and Robert Bosch North America Corp., signed an agreement to form a joint venture to develop and manufacture geothermal and water-source heat pumps for the North American residential and commercial segments, the companies announced recently.
The season was getting colder and heating calls were beginning to come in. Bob and Tim were riding to a large residence that had three heat pumps to provide heating and cooling for the structure and Tim asked a question, “Why are heat pumps so popular?”
After strong January numbers, United States combined shipments of central air conditioners and air-source heat pumps have shown another upsurge, totaling 357,637 units in February 2013, up 20.8 percent from February 2012, according to the latest statistics from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
CO2 as a refrigerant in cascade supermarket systems, transcritical applications, transport refrigeration, and heat pumps were among major developments in recent years. Here is a summary of those developments.
The refrigerator is actually a heat pump, as the method of operation is identical apart from one difference: Heat is extracted from the refrigerator and discharged into the surroundings, whereas the heat pump uses the thermal energy in the surroundings for heating purposes.
