Upon our arrival we performed the approved repair for the refrigerant pressure control. Recovered all refrigerant from the system, installed new refrigerant pressure control, new filter dryer, purged and pressure tested with nitrogen then brought the system down to a proper vacuum. Recharged the system with 10 pounds of r410a and ran a performance and safety testing finding everything operating properly at this time. I then performed both 6 month check ups on the 2 heat pump systems. Flushed and treated the water removal systems, cleaned and sprayed the electrical cabinets with electrical insecticide, washed the condenser coils with water and verified system safety and performance. Everything’s operating within manufacture specifications at this time.
