Understanding how outside temperatures affect heat pumps

Posted by

“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.”

Now here is an example of how proper training and understanding in the HVAC industry is critical to providing the best service possible. Determining what is an anomaly versus what standard operating conditions for an appliance is not only has cost implications but could affect safety too. Homeowners need to trust and rely on their contractors to make the best decision possible on their behalf. Inaccurate diagnostics will likely lead to problems at a later date.
