I’ll add to the crazy anecdotes with something that happened to me a few months ago.
I had a brand new AC/heater hvac system installed last year. Encountered this problem, the AC would just turn off. First time, called the AC company and they come out. After a few visits, they pinpoint the problem as the condensation pump, it’s just a small water pump that’s down in my basement to push water out a little PVC pipe. When the water fills up in the reservoir, a pump kicks on and moves water. If the water gets too full, a sensor turns the AC off. After the rd visit they decide that “the grade isn’t gradual enough and the pump turns off”. They replace the pvc. Fourth attempt they replace the pump, pump must have failed. Fifth visit, they replace the pump with a different brand. Sixth visit they disconnect the automatic shutoff of the AC, my basement floods with water. Seventh call they change the pvc pipe again. Eighth call they are baffled, say everything is working as it should, give it time.
After they leave, my wife goes “whenever I turn the basement light on, I hear a weird noise”. I immediately turn the switch off and walk down into the basement and test the outlet. The light oddly enough controls a random outlet the pump was connected to. Every time a tech came over, they turned the switch on.
I still wonder how many more phone calls it would have taken before they figured it out.
