Upon my arrival I evaluated 1 heat pump system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. I found that the indoor unit was very dirty and the pressures looked lower than normal. I recommended a cleaning, uv light, and also presented an estimate for a premium thermostat at pattys request. The repair option for the cleaning of the indoor unit was approved and the options for the uv light installation and the thermostat were declined at this time. I let patty know that our office will be in contact with her regarding the scheduling of the repair. I also let her know that I would like our team to re examine the pressures on the outdoor unit once the cleaning is done to verify if we need to recommend repairs.
