I'm in lower Alabama, when we're home and the RV is plugged in the AC runs most of the year. Humidity and heat will kill the interior if you don't. As a bonus it is really nice to be able to board the RV and not feel like you're walking into an oven.

Hello, Neighbor. Same here, we leave the salon A/C on all the time, and the only issues we've seen have had to do with the wall-mounted thermostat that controls both roof units.

Occasionally, I'll enter the coach and it's warm, and the thermostat reads 00, with the mode on unit 3 (which we don't have). A/C is not operating. Trying to turn it to the BR unit (2) doesn't work, so remove the fuse for 20 seconds and do it again. We've bought a new thermostat, but no change, so if the fuse doesn't fix it (which is a reset, not blown fuse) I swap out the thermostats.

Having a cool coach is worth it's weight in free diesel

YES 24/7! I'm in Bakersfield, we have similar weather, similar humidity, heat and cold temps. For the past 3 months our home has been going through a major remodel so we have been living in our Class A 2003 Newmar Dutch Star...it's been soooo nice living in 320 sq feet that I'm scared of going back to the 2,000+ sq foot house! hahahaha

These are the steps I took:

#1 I prepared by cleaning my roof with Dicor Rubber Roof Cleaner and then used Dicor Rubber Roof Protection...that was a full day affair. I have a Brite-Tek roof w/ 7mm Decking. Brite-Tek is an EDPM rubber product.

#2 Then I had both of my 2 x 13,500 BTU Penguin Central Air Conditioners professional cleaned and serviced to include all coils. My AC's are 16 years old and original. They both passed with flying colors and I have 96,000+ on my rig.

#3 Then I closed all blinds and used Double Bubble Reflective Foil Insulation (24 inch X 10 Ft Roll) Industrial Strength, Commercial Grade, Radiant Barrier Wrap and surrounded my windows. I also have a magna shade placed on outside windshield.

With all this, my AC is not actually ON all the time. It is pretty cool in here even when we experienced 108 degrees. I have it set at 78 degrees when I am out, and when inside I bring it down to 76 or 77 degrees and have had no issues.

Since I am not using the home AC, I have not seen an increase in my AC bill...but both home and RV are not on simultaneously in my current case.

Hope this helps!

It would just make it ware out sooner.

we run our AC as weather conditions require.

We have a 2019 Forester by Forest River and it has really been hot in the south east. Our a/c unit has been keeping up nicely in the low to upper 90. I noticed that it runs 24 hrs non-stop all the time. You can hear the compressor kicking on and then it would kick off but the fan runs constantly. I questioned that when I had it in for other warranty issues. They called Dometic and they told the tech that was designed that way. So I don't know if all of are that way but thought I would mention it.

I would think regular maintenance would be very important if running 24/7.

Ok to run one constantly on 20amp circuit?

Run it constantly when humidity is low. High humidity would cause ice buildup but with low humidity no problem.

I don't know if this helps but we are snow birds and leave our 5th wheel in Florida during the Summer (unless we are traveling in it). We leave the A/C on with the thermostat set at 78 degrees primarily to keep the humidity down, which may not be an issue in the desert. Our monthly electric bill runs about $30 just for the trailer A/C but is worth it to prevent any sort of mildew. We monitor the temperature and humidity 24/7 via the Internet to be sure everything is working OK. The daily temperature inside the RV has been 80 degrees with a humidity level of 49% (averages). We have had no issues with moisture building up over the past 4 summers. 2005 Doubletree Mobile Suite, 36ft.

If you leave it running with doors and windows closed, the inside won't build up humidity.

Too stinking hot in Georgia to turn it off.

24/7, 365.
We keep our 40’ DP at home as a guest house, emergency A/C source, etc and it stays plugged in and A/C on 85. Saves the wood, saves the glue joints, protects most everything. Our 19 y/o RV still looks factory new inside because of this care. Sure, hits the electric bill but our RV looks and wears like brand new inside because of this extra care.

We leave our A/C set to 85 when parked, not in use at home. It cycles as it should. When we're in the MH, it's set to 75-80. It's been steadily 100+ in FL until the past few days. I like it cool inside to keep it like the house (77 all the time).
