The air compressors for the upstairs and main level went out today. Both units are around the same age but I doubt both units would go out at the same time. I flipped the inside breaker switches on and off and still nothing from the compressors. The inside units still blow air. But the fans on the outside compressors aren't turning. I also flipped the outside switches that are above the 2 outside compressors and still nothing.
Is there anything else I can check?
