When I got home from work at 5:30 today, the house seemed a bit warmer than usual. We keep it set at 80° F. when we're away, then crank it down to 75° F. when I get home. It was 85° F. when I arrived. It was 107° F. here in Arizona today, but this unit has always been able to maintain any temperature we set, even with outside temps as high as 117° F.
The air handler inside the house was working, as was the fan at the top of the compressor unit outside. I checked all the circuit breakers both inside on the main panel, and on the outside box leading to the compressor unit, and unless there's an internal breaker or fuse inside the compresor unit, I'm betting on a bad compressor or sudden loss of coolant. We have not noticed any gradual decline in cooling.
The system is not yet two years old, so I'm sure it's still under warranty. Given that, I don't want to mess with it.
I'm waiting until my other half gets home to dig up the papers on the unit so that we can call for repair.
Can anyone think of a different problem than what I've outlined?
TIA
