Upon my arrival I checked into the concerns the tenants had with the system not cooling below 72°. Performing my diagnostics I found everything on the system is operating properly at this time. When I checked the comfort controls they were both maintaining 71° within the home. I did find the pressures to be slightly off and the condenser coil to be dirty. I washed the condenser coil so I could get a more accurate read on the pressures. I recommend having the systems charge recalibrated and having a yearly maintenance performed in the system.
