Please tell me I can expect more than......

Than 81 degrees out of my one AC! I had the AC on all night when we brought it home, I set it on 80. The following morning, about 930,I turned it down to 76, By noon it was 84! it was hot outside but started out the day in upper 80's the by noon it was low 90's. I know lots of people have two units, but I didnt know it was mandatory......Tell me I'm low on freon!

Humidity has a big effect on cooling. If you set it on 80, your AC should have cycled enough to de-ice the cooling coils. If your AC is not cycling, something is wrong.

Now if you set it lower, say 65 and it is not cooling, my money would be on icing. Try raising the thermostat and putting the fan on low. This should improve your cooling. (sounds backwards I know, but it works).

Low Freon could be a definite cause, but your AC is pretty new to be low.

Filters clean? Smokers can gum up the filters quickly.

If nothing helps; time for an expert.

I didnt check the filters, we just got it home wed (brand new). the air is cool but not cold. No smoking but I guess it could have debris in the filter from manufacture. When I first walked in that morning it was off, it came back on when I set it on 76, so It's cycling just fine. We are leaving for the hill country tomorrow morning and I dont want my babies to bake all weekend!

Take a temp reading and measure the discharge air, you should have about a 15 degree drop from the temp inside the TT. That is to say if your unit is 80 inside the temp should be at about 65 coming out. Try to run the unit on low and check for condensation water dripping off the unit. If you freeze your coil up due to low freon you will not feel any air or maybe just a little......

We have the 320 with just one unit,and cools ok.If the outside temps climb into the high 90's and we set the thermo on say the lower 70's early in the morning and set the fan on high,it will hold it into the high 70's.It could benefit from the second unit which it is wired to accept.However we aren't often staying in the RV during the day.Keep your curtains down,we also have these thick foam squares that we stuff into the 3 ceiling vents which IMHO do help.

That helps me. Yours is longer than mine, so maybe it's something simple. Is yours 50A?

On a 30 amp site your 20 amp duplex may be piggybacked off your 30 amp socket. This will limit you to 30 amps total even if you use both outlets.
On these type sites you can use one or the other but not both.

If you have a 50 amp site the 20 amp duplex will be wired off the unused leg and you can get a few more amps that way. Campground may not like it though since you are using more amps than you are paying for.

I usually use the extra 20A in the mornings for my griddle, I've never ran into one that wouldn't run both. I just hope I don't, if I need it! Thanks
