HVAC testing at 60 Degrees F

[Dan Bowers, CMI]

George -

Lotta reasons an A/C breaker can trip (including a bad breaker) that have NOTHING at all to do with the ambient temperature.

If it was 34 degrees this AM and at 2:00 PM it hit 60 degrees and you turned the unit on / its possible you could send liquid back to the unit and cause a pressure that trips something BUT if that temperature scenario was not present - I would be more inclined to look elsewhere.

Regardless - Refer it to a HVAC contractor for service and correction.

The breaker tripped because of a system problem, not an inspection problem.

Rule of thumb Now we are going back a few years Mind you, We where taught No heater it had to be 60 For 24 hours, As David said in this area it is 60 by 10.00 and be 25 at night.
I will not take the chance. Because some knuckle head ac guy will threw you under the bus to show how good he is.
