Upon my arrival in Muldoon I found that the refrigerant pressure control was not metering properly. I spoke with the customer about his different options for repair and he chose to go with HI2E. Will need to schedule a time to return for 2 techs 4/5 hours. Customer would like to have window units if the repair is going to be later then this coming Friday. He has 2 systems one is a Goodman and the other is a York both in the attic. The system that is not operating properly is the York system. Spoke with customer about our maintenance program and he is going to pass on it due to the fact that he may be going into assisted living soon.
