Tech Cody arrived to customer's home and met the homeowners. I ran tune upstairs on two mini splits and the furnace on the main house. BARN HOUSE: Mini split filters clean, evaporator coil clean, blower wheel has minimal dust buildup. Compressor and fan motor were operating within manufacturer range, I washed and waxed the unit, refrigeratant charge acceptable at this time. STUDIO: Customer expressed concerns about the studio mini split not putting out cold air. I found that the outdoor unit was extremely dirty and was not getting airflow across the coil, I washed and waxed the unit. Compressor and fan motor were operating within manufacturer range. The refrigerant charge was within acceptable levels at this time. The indoor filters were clean, the evaporator coils were clean. The blowers had some dust buildup. I also noticed that the remote seemed to be operating unusually, the homeowner said he noticed the same issue and had ordered a new remote. MAIN HOUSE: Filter needs replace
