Ok so, daiken heat pump with electric air handler, when it was dropping to like 25 degrees F aux heat would come on, and it would run , but at some point the breaker for the electric air handler tripped , I checked the 3 amp fuse and it was good. I reset the breaker and when it got done to 20 at night again , it tripped, but since then it has tripped again . This is at a jiu jitsu gym , there is two rooftop units for the up stairs and part of the downstairs is heated by the heat pump and air handler. The filter was clean. They called the people they have a contract with , and he came to check it out the outdoor unit only, he checked the compressor windings and the starting amps both of which were within range, he did not check pressures, or the contactor , and it sound like he didn't look at the indoor unit at all. (I was reading the notes, this is a gym I train at, so I will advise and help them, but they have contract with an old company I worked for and they constantly were ripping of the gym so I double check their work now)
