On arrival customer stated the master bedroom system and upstairs system was not cooling correctly. The upstairs system was low on R22 refrigerant, homeowner requested top off that system. I charged system with R22 refrigerant 3lbs and tested operations everything is working properly at this time. The master bedroom system was extremely low on refrigerant and homeowner requested a leak search on system. I discovered a pin whole leak inside the evaporator coil towards the backside & also a leak on the condenser front bottom of the condenser coil. Customer request quotes on master bedroom ac only and heat pump ac only quotes.
