Diag/ system wasn’t heating properly this morning but started working again, customer would like it checked. Tested system in heat and cool modes, checked amperages, tested capacitor ratings, and system is working properly. Found the filters are a bit dirty and the evaporator coil and blower wheel are starting to get dirty, didn’t find the CoreSense tripped on high pressure but let customer know maybe this is what happened, changed filter and tested system and it is working properly. Sent estimate for duct cleaning per customer’s request.
