Can you provide model on outdoor unit and indoor unit and Can you feel of the large copper refrigerant line that runs between indoor and outdoor and tell me if it starts out COLD and then changes to Hot or just changes to ambient temp when this happens.

FEELS COOL
Customer: replied 7 months ago.
THE AIR MAYBE JUST WARMING UP DUE TO NOT COOLING
Expert:  airheatman replied 7 months ago.
Thanks for this information. When it is cooling, does that line get "beer can co0ld",
Customer: replied 7 months ago.
NO
Expert:  airheatman replied 7 months ago.
OK it is vey likely the system is low on refrigerant.That line should be as cold as a beer can out of the cooler.If not, this implies either compressor is not pumping or we are low on refrigerant.If this is the case, the outdoor unit may shut down on low pressure.After a short time when pressures in system equzlize, it will start back and run a short time. Have you noticed outdoor cycling off while still calling for cool?
Customer: replied 7 months ago.
NO I HAVENT NOTICED I AM NOT OUTSIDE
Expert:  airheatman replied 7 months ago.
That would be first thing I would check.Also do you have access to gauges to check the charge?
Customer: replied 7 months ago.
I HAVE CALLED A AIR COMPANY TO COME OUT
Expert:  airheatman replied 7 months ago.
Thanks for allowing me to give you some ideas.If you do not have the gauges to check charge and tools for testing, that is gong to be the most practical thing to do.
