Every year, the U.S. Environmental Protection Agency’s (EPA’s) Energy Star program acknowledges products it deems “Most Efficient” in the marketplace. Here is a snapshot of Energy Star’s Most Efficient Geothermal Heat Pumps of 2015.
Performance-based contracting involves HVAC professionals measuring the live, installed field performance of systems to ensure customers are getting what they’ve invested in. The field-performance measurements obtained by an HVAC professional are then used to rate the operating efficiency of the installed system.
The emergence of the smart home, interconnectivity, and a push for efficiency stemming directly from the White House is revitalizing HVAC equipment. Here are some up-and-coming, game changing HVAC components and technologies designed to propel the industry forward.
Installers and specifiers know a gas appliance is only as good as the venting system it’s connected to. Poor venting can cause improper combustion, but, more importantly, can also lead to flue gas leakage into heated spaces — a problem with deadly consequences.
