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, thanks to the growing demand from building owners and managers, who are looking for ways to save energy.
The Department of Energy (DOE) is also encouraging owners to replace their equipment with high-efficiency systems, noting that many rooftop units, in particular, are past their typical life spans and function at much lower efficiency levels than new units. With the large stock of aging commercial equipment out there, now is the perfect time for contractors to help owners and managers think proactively about replacing their old units with more efficient heat pumps.
