York Affinity residential air conditioners and heat pumps earn designation for fifth consecutive year
March 11, 2016
Johnson Controls announced that two of its York Affinity residential air conditioners and one York Affinity residential heat pump have been recognized as Energy Star® Most Efficient 2016, when combined with the York smart thermostat.
Tightening a home’s envelope may reduce the air supply needed for combustion, and when there’s not enough combustion air, equipment could have combustion ventilation problems. Thus, the people who sealed up homes (often referred to as the weatherization industry) needed a way to determine if sealing a home up would undermine the safe operation of combustion equipment. To meet this safety need, they embraced combustion appliance zone (CAZ) depressurization testing.
The ASRAC established the Central Air Conditioners and Heat Pumps Working Group in July 2015; it is the latest of several working groups to successfully create negotiated efficiency standards for industry equipment. Other negotiated rulemakings aided by working groups include walk-in coolers and freezers, regional standards enforcement, and commercial rooftop air conditioners and furnaces.
In this troubleshooting situation, you are responding to a customer’s complaint about their heat pump, and you’re not the first technician called in to solve this problem of “not keeping the home comfortable and running a lot.”
