Sounds like under sized duct. Might not have enough return either. How thick is the insulation.
sooo yesAll the ducts are insulated flex duct running off a main fiber board trunk.
OH, that dirty thing is the evap coil. I couldn't see it at first through all that dirt.Your evaporator coil is more than 50% blocked so all heat that is supposed to be picked up from the living space is not being picked up and distributed to the outside condenser and out into the air. You are recirculating the same heat and not removing any.
You need a severe evaporator coil cleaning and I'd be willing to bet a condenser coil cleaning as well (to be able to get rid of the heat) and an air flow static pressure check to certainteed that your system is moving proper air flow and proper air flow is mandatory to system charge.
Have your coils cleaned alone and you'll drop 10 degrees supply air, gauranteed.

The sad part is I've had one guy clean it and 2 other AC techs come out and tell me there was nothing wrong. Yet with one little picture u guys pointed it out. Now how the hell should I clean this thing? Go at it with a can of evap coil cleaner? I don't wanna take it out of the system.
