Customer stated that unit was not operating and nest had no power. Inspected package unit on left side of home. Found that there was power coming into the fuse blocks but no power coming out. Tested fuses and found them both had failed, Replaced and unit kicked right on. Fuses are rated to 60 unit is only pulling a total of 24 amps. System is operating at this time with a proper 20 degree temperature split. One duct in room above garage still needs to be Changed out. They would like a quote for replacing the package unit as well.
