Even though Air-Conditioning, Heating, and Refrigeration Institute (AHRI) reported that air-source heat pump shipments in 2012 decreased 3.8 percent from 2011, there is no question this equipment has become increasingly popular over the years. Consider that in 1992, only around 800,000 units were sold, but by peak-selling year, 2005, that number jumped to over 2.1 million.
Manufacturers predict that sales of air-source heat pumps will continue to increase, particularly in colder climates such as the Plains states, Midwest, and Northeast. Heat pumps have not typically been as popular in these areas, as their performance suffers during extended periods of subfreezing temperatures. That’s why most heat pumps in colder climates still require some sort of backup heat — often an oil- or gas-fired furnace — but they are an excellent option that can provide customers with a more energy-efficient year-round solution.
