I have a new American Standard 13 SEER,2 1/2 ton, 410A heat pump and matching air handler, installed by certified technician. Two questions, ie: second opinions needed--
1. My heat pump runs nearly all of the time at night, early morning and on cloudy days expecially. It maintains set temperatures, but runs nearly constantly to do so. This happens even when the outside temps are 30 to 40 degrees. It rarely cycles, just seems to run about all the time. Is this operation normal?
2. My heat pump doesnt defrost until it is really loaded with frost/ice. Ice covers the coils, and associated parts outside the coils and runs that way for hours before finally defrosting. Is this normal operation? It seems to me that it should defrost a little sooner or more frequently. Is this adjustable?
