Standard reset I have an American standard heritage 15. The fan comes on, but still not getting cold air in the house.

SOURCE: No cold air coming from the registers.

If your compressor is running outside (low hum noise) then your probably need freon .If the compressor is not running could be a bad cap or bad compressor

Sorry no easy answer if any of the safety switches tripped you have major problems. If your fan is coming on when switched to fan on then your problem migth be outside in the condenser. Check your power and breakers going to the condenser.

My AC works great, cold air coming out of the vent (about 63*) intake working well also. (about 76* in the middle of the day)
Think it could be the insulation?

Sounds like motor has failed. If the red light is blinking it may be telling you what is wrong by the number of blinks. It maybe locked out for some reason or loose wire. Try turning off breakers to inside unit for 5 mins and try again, this may reset unit. But it sounds like a bad motor or circut board. Try running with stat in on position instead of auto in cooling mode.

clean outside fins and check freon level
