Installed new system in Fairburn Ga
Maintenance/tune up completed in Fairburn Ga
Found no issue with upstairs thermostat. Thermostat is operating equipment however equipment was very low almost empty on R 22 refrigerant. Not cooling. Performed maintenance on both upstairs and downstairs systems. Replaced both 14x20x1 filters. Downstairs system is cooling normally. Back to upstairs, spoke with customer about significance of upstairs system and its low refrigerant condition. Customer wishes at this time to add refrigerant to system so that it can cool but she would like an estimate on system replacement. Customer was informed that should she replace this upstairs system we would discount the amount she spent on refrigerant. Added 5 lb 407c refrigerant to upstairs system.
Residential Service Call Completed in Fairburn Georgia.
Upon arrival, found the thermostat installed during the previous visit is working correctly. The customer stated that the system is having a hard time keeping up in cool mode during the day. The customer stated that the temperature never gets down to the setpoint on the thermostat so the system runs constantly. Found LED trouble code on the outdoor package unit showing high pressure lock down. Reset the system by removing and replacing the service disconnect plug. Found system operating in heating mode while called to cool indicating the thermostat was set up to energize the reversing valve in cool mode instead of heat mode. Adjusted the thermostat to run the reversing valve in heat mode and checked the operation of the system and pressures. The system operates normally after adjusting thermostat settings. This is a warranty job.
Thermostat locked and could not unlock it. Replaced the thermostat so they can control it again and showed him what to do.

4 ton 14 seer heat pump system
I performed a cooling maintenance on three heat pump air handlers I replaced two 18x20x1 filters and the other filter is a 16x20x1 I checked all electrical components and cleaned all drain lines and checked the temp drop on all units on the upstairs unit I found that it did not have a temp drop and when I checked the Freon levels I found that the upstairs unit was completely out of Freon so I recommend replacing the upstairs unit I also checked the capacitors everything is in good working order at this time for the main level and the basement unit.
