Upon my arrival I evaluated 1 heat pump system and 1 electric straitcool 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. Found the pressures low for the upstairs unit. Recommend a leak search and adding refrigerant, I also checked with the electronic leak detector but did not find signs of a leak. Michelle chose to wait and see how the system performs.
