Welcome welcome to Just Answer!. Tell me please how old the unit is approximately, and if you live in the city or the country and if you have pets or not.Pet hair and dirt can clog the condenser and cause that problem. The condenser may look clean but actually be clogged with dirt **between** the finsTell me when the problem first started.There can be other causes as well, such as a poorly trained technician putting too much refrigerant in the system. We need to do a few tests to see if thats the case or notFirst test:
Put a thermometer in the cold air outlet closest to the furnace or air handler.... tell me what the temperature is after 4 minutes..... then use the same thermometer and put it in the room near the return air grill and tell me what the temperature is.
Tell me if you turn the AC on in the morning and leave it on all day, or do you wait until the house is hot, then turn on the AC
Tell me if the AC goes off by tripping the breaker or not. What do you have to do in order to get it running again.
Please try to answer each of these questions in detail, I need all that data in order to do a proper diagnosis.We can go from there until we get this figured out with no time limit.
four dogs in house, live in suburbs, been like this since i lived here bout 4 years, doesnt trip breaker and comes back on by its self when temp drops outside
