Did leak search. Upon completion of leak search (pressure test found system not leaking any refrigerant at all. Informed customer that last company could’ve let the refrigerator out. Added all refrigerant to system and tested system (8 pounds). Gave two pounds to customer for free. When testing system found reversing valve not shifting. Customer likely has bad T stats. When we return on Friday to do zone board changeout we will test everything and ensure the T stats operate properly. Was able to get him heat till we return. CUSTOMER AWARE 410 IS NOT WARRANTY. Cleaned coil today. Forgot to add to today’s invoice. Added to estimates to collect payment when we return on Friday.
