Smile Air conditioner

I'm new to this forum. Just bought a 2015 35 um Precept. It is 100 degrees today with high humidity. I have both air conditioners running all day. It won't cool below 95 degrees. Anyone else have ths problem?

I don't have your unit but that doesn't seem right at all.
We've had some mid 90's days with high humidity and our main unit easily keeps the coach in the low 70's with very little help from the second unit. The bedroom unit will come on occasionally but does not stay on constant and the main unit cycles on and off as normal.

Our dual A/C units will manage to keep things pretty nice. I tried shutting one down during the day and once the remaining unit got behind I turned the second back on and they spent till early evening catching up.
A little shade goes a long way to helping out the A/C units.
I open the "quick cool" vents on both units to let the cooler air dump directly into the living space rather than relying on the ducting to distribute it.

You have something not working even when it was 105 we cooled our unit down to 75 with just one a/c. Check that you have air comming out all the vents and then make sure the compressor is kicking in not just the fan.

If you have a thermometer (preferably IR) check the temperature of the air going in the intake, and the temperature of the air coming out. The air coming out should be about 20 degrees cooler. Also try to park in the shade if possible.

Not sure of the AC unit but make sure it is selected for cool and you don't just have the fan on circulating the hot air,also make sure your getting power from your hook up if your not running generator,i believe the fan will run but the compressor wont kick in if theres not enough power

I agree. We have a Precept and initially had one unit not set to Cool+Auto and wondered why it didn't cool properly. We are running in similar ambient conditions and the two units do run often but keep it cooled into the low 70's easily. Open the vents on the main rectangular portions initially and once the temps approach a comfortable level, close those vents and use the ceiling vents to better direct the cool air to where you need it.

We've always struggled with our A/C. For some reason, The compressor on our unit will stop. The fan keeps running so you think it's cooling, but notice that temp is creeping up. A quick check of the air coming out and it's not cool. We have to turn it off for several minutes and then it will work again. As stated above, check the delta between the return and supply grills. Should be at least 20 degrees.
