I went over my concerns with the customer and he approved HT4C. 10% was collected today and a return will be scheduled.

Upon my arrival I spoke with the customer about their concerns with the system not cooling. Performing my diagnostics I found the comfort control circuit system is faulted not sending cool call to the indoor system. I spoke with the customer about their repair options and went over maintenance. Customer approved repairs today and signed the rental on to out maintenance program. Return will have to be scheduled preferably in the morning since this is an attic systems. Customers gave door code and gate code to gain access to the home since it is unoccupied and they may not be in town.

Upon my arrival I checked into the concerns with the back system not cooling properly. Performing my diagnostics I found the pressures and temp split were good. I checked the vents and found that a few of them were shut down to allow more airflow to the daughter’s room. I helped the customer with balancing the vents to allow airflow to all areas and informed her they may have to make adjustments as they go. Currently all areas are cooling well. There are no blinds in the daughter’s room allowing sunlight to enter as well. I advised on blinds and blackout curtains.

Upon my arrival I evaluated 1 furnace system & 1 mini split system 2 heads & 1 outdoor unit. I verified system safety and performance is to manufacture specifications.
