For this job, the customer was having problems geothermal not heating. So I proceeded to check the unit and found a five amp fuse was tripped. While I was checking the geothermal, I had the system on emergency heat had a temp split of 61° and 118°. After I reset the five amp fuse, I turned the system back on the heat pump and was able to get proper readings. I had a temp split of 61° and 92°. I also checked the water split and the temperature of the water as well The customer said they did not have this unit service for a while, so I recommended the customer having a tuneup done to this geothermal. The customer wants us to come back and do a tuneup. I did not find any other issues with this system
