bet that dude was R12 and probable low on gas. Mine, a 2005 15K btu is R22 and seems to do a good job after cleaning both indoor and outdoor coils last year. The fins can get so dirty they do not absorb or release heat well during operation.
I have a Bullet Piercing Valve I was going to add to check Freon pressures when it finally get warm around here and not raining..
anyone know the Delta T across the coil.. in home systems its 20° more or less across the coil.
guess Coleman might be the go to for replacements.

A noisy sucker :>( Only 3 years of light use and the Dometic lost Freon. I replaced them both. Now I have 2 15BTU Coleman a/c... "I Shell Never Be Hot Again"
