AC not getting super cold

[NCMODELA]

Hi all, we have a 2011 keystone summerland and last few years it would get so cold inside we would have to turn it down. We are out now and it's just keeping slightly cool. We cleaned air filter but any other options? I have noticed there is not as much water running off of camper.

Thanks bill

This. when the sun is out my AC has a hard time getting to a difference of 15 degrees.

Great answer Old-Biscuit!

If you are in a southern state you need to clean the coils and often.

I lived and RV'd up north and never had problems with my ac until I started RV'ing in the south. Those coils get algae and green mold on them. I had to routinely clean the coils while in the south.

Check to make sure the tube that drains the water isn't clogged. Also, it works better on high than on low.

I found the foil tape was falling off at the air outlets letting it blow into the ceiling cavity. Also check the baffle between the intake and outlet duct in the ceiling grill area.

Sounds like you need to step up the frequency of routine cleaning.....

Need to clean return air filter more often.
Need to clean EVAP Coil (air exchange cooler just inside where filter is)
Need to clean drip pan and drain holes (under evap coil)
Need to clean Condenser Coil (coolant exchange cooler under roof shroud)

Wash and clean fins on unit on top. Try to not wash so hard as to bend fins.

Also it is common for a sensor that is mounted on the coils just above the ceiling plate. The sensors will come loose and it will cause the unit to ice up which makes for not so good cooling. Make sure the sensor is in place.

Most common AC issues are freezing which happens mostly because your running on the AC on low vs high ... turn the AC off and see if you get water running off from the ice melting. Another issue is dirty evaporator coil - that's the coil which few ever clear because it's hidden under a sheet metal covering on the roof of the RV ... SB lots of threads on that subject.

The obvious question would be what is the outdoor temp.. but that's too easy.

Only thing that I know might affect it is the CG power. Can you check the voltage ?

I'm not sure why it would get too cold, unless a) you've set the thermostat too low, b) your thermostat is not working properly. Nobody on here has an a/c that works TOO well.
