Customer reply replied 11 months ago
Tech. cleaned inside coils yesterday, said had mineral deposit. Did not help. Just checked outside lines they are dry.
Customer reply replied 11 months ago
Both outside lines are warm to touch.

Means the compressor is not working, if may be a bad start capacitor, is the fan running of outside unit?

Ask Your Own HVAC Question
Customer reply replied 11 months ago
fan runs and house will cool down to around 78 degrees, but unable to get below that temp. Plus unit does not shut off, but continues to run have temp set at 76 degrees. Humidity stays over 75 percent and will not lower.

Humidity and heat will not get better if the compressor is not running. again, while outside fan is turning, the bigger copper line needs to be cold and wet???

At this point will need tech back out and have complete system checked. He was focused on the inside part of the unit so should have checked the outside as well it seems. Thanks for your help at least I have an idea where to look. The big line is not cold to touch.

Probably just a bad capacitor
