A/C on When Connected to 110

wow, folks really?? So these roof top RV AC units are made to run 24/7/365? I realize folks full time in them and realize folks do use the AC...but really? Your going to try and tell me that the roof top AC unit is going to last like a S&B unit? Many folks that full time realize they have more repair costs with some equipment as compared to a S&B home...Notice I said some? Not everyone realizes this. Not everyone realizes many things in an RV do not operate or do have limitations unlike our S&B home equipment...

I was simply trying to let the OP know...the life expectancy of an RV rooftop AC unit is NOT that of a S&B AC unit...and with the size of the RV....and the heat gain these things have....1 AC unit may never dehumidify to the OP's satisfaction, especially if the coach is parked in high humid areas with 90+ temps and happens to see direct sunlight....If an AC unit can not overcome the heat(due to being overworked), it can not attempt to dehumidify....right?

SO before being SO quick to bash....think a WEE bit first!!

I wonder what full timers do?

They do what everyone else does, run the AC. As long as the operating pressures remain within the correct parameters, it will not hurt a compressor to run non-stop.

Yup. My point.... Every now and then I wonder where some posters on this forum come up with their ideas? Many times they are obviously not well thought out.

Bad question.. 110 at 15 amps may run one AC

110 at 20 amps will

110 at 30 amps is a 30 amp site in an RV park

110 twice at 50 amps each is a 50 amp site in an RV park.

Though 120 is better in all cases.

When I had a sticks and bricks I put an "RV PAD" next to the detached garage. it had 120 volt at 20 amps and I often ran either a space heater OR the air conditioner, no problem.. So long as I kept the wife out of the RV that is (She seemed to have a knack for tripping that dang breaker)

How about 24/7 365, 9-years? Yeah stuff is going to wear out. Balance the cost of repairs or replacement of the unit to ruffles style walls, furniture, and rotten fabric and mold saturated foam cushions. High humidity is no joke. I'm sitting in 89% R/H at the moment.

I am going on six years now running two RV Trailers in my back yard from 10 Gauge (10-3) 50-foot extension cords plugged into separate 120VAC 20AMP circuits in my garage.

My OFF-ROAD POPUP trailer is my working in place mods for camping off the power grids and the fifth wheel is the second home bedroom and added fridge for the house.

Kinda neat to have a place to getaway even at home to watch some Football and NCIS. The visiting grandkids have a ball using the trailer when they spend the nights...

Works for us...

as inefficient as the roof AC units are due to the heat gain of these RVs...1 AC may not do a thing for humidity control

Where did that come from ??
That is what an A/C does, removes water from the air. That's all it does,.....that's what its designed to do.

And running a unit continuously, no cycling, it much better for the longevity of the unit.

That was one of those all to familiar "my cousin's uncle's brother-in law said" posts. Maybe the poster has never noticed the water dripping off the roof while the AC was running.
