Last summer I did not think the AC had the cooling it should have.

I have 1,226 hours on it.

I pulled roof and took the top cover off from the HVAC unit.

The evaporator was about 50% clogged with something that was hard enough that a blow gun would not touch it.

The fins are really close together.

I brushed it off then soaked it in evaporator cleaner. Then I rinsed it with water.

Where the ceiling and the rear corner posts are it is not a very good seal. There was dust on the inside of the roof there.

Sorry I did not take pictures before I cleaned it.
