Another homeowner with AC problem

during the day the temp at the supply is warm. At night it gets nice and chilly.

Last summer the ac had no problem maintaining 78 during the day and 73 to 74 at night. 3 ton unit on 1000 sq ft house.

Little background:
this weekend hosed out the exterior condenser from the inside out.
Got in the attic pulled the panel and inspected the evaporator, clean.

thanks for the help.

Temps

Without actual temperatures we can't help you much. With 3 tons in a 1000 sq. ft. house, it should cool with little problem unless you have virtually no insulation. Measure supply & return temps as close to the air handler as possible & let us know. Also check the ducts for missing insulation &/or leaks. If the ducts are in an attic, tight returns are a must.
