You are currently viewing Understanding how outside temperatures affect heat pumps

“On a cold, wintry morning, when a home needs the most heat, a heat pump’s heating capacity is low. That afternoon, when outdoor temperatures warm up, not as much heat is needed and the heat pump capacity is much higher. Let’s take a look at how understanding this simple fact can make or break your diagnostics.

In the morning, a heat pump may deliver only 5,700 Btu per ton and have a 13ºF temperature rise. That afternoon its capacity may increase to 13,400 Btu per ton with a
31ºF temperature rise.

A newer technician may think this system has big troubles. However, a master technician understands it’s a normal system response to outdoor air temperature changes. A technician can refer to the manufacturer’s heating capacity tables to interpret heating capacity and temperature rise, then correctly diagnose and repair system problems.”
