Air Conditioners while not in use in the summer?

I have full power to the coach while it is parked in the back yard and keep my air conditioners turned up to 85 in the heat of the summer.

I was told this is better for the coach than letting it get so hot and humid and sticky inside, which destroys the interior over time.

I was thinking maybe I should shut the A/C units off and just turn on the fantastic fan very low.

My concern here is the premature wearing out of the A/C Units......?

Thoughts anyone?

I am aware it is costing me a little extra on the power bills, but that's not what I'm concerned about here, so please respond to the A/C unit usage/lifespan...thanks!!!

It is probably better for the units to run than to just sit and cook in the heat. Running the units keeps all of the various fluids flowing which is a good thing. (Just my opinion) I leave the units in my coach set on 80 and let them run as needed.

I would think the only one benefiting from leaving the A/C on (even at 85) is the electric utility company. Leave a roof vent open (under a vent cover) and a couple of windows open a bit to allow air flow.
The cost of replacing the A/C units and utility costs would be more than 'interior destruction.'

Take more trips!

In very hot weather I set the AC thermostat to high temperature so it runs in the worst heat of the day to keep the coach from becoming a zillion degrees inside during storage between trips.

Electric cost for me is 17cents/hour. For $5G's I put up an aluminum 40' garage...it'll take jus' 55 years to recoup.

I'm definitely not an A/C tech so I don't know whether or not it's good for the units, but I keep one on and set to 80 degrees through the summer when we are not traveling. I alternate the two units.

Living in Vegas, during summer when coach stored on our driveway, I leave both AC units on with t-stat set to 89. Been doing it now for 14 years and so far no problem with AC units--Knock on wood

Safe Travels...

I'd like to cover the top of the MH with a tarp to keep the sun and pine needles off of it.

It looks like this won't affect air flow from the A/C units since the vents are on the sides of the shrouds, but anybody have carnal knowledge of doing this?

Bamaboy, be very careful that the tarp doesn't restrict the air flow or cause the air to short cycle back through the condenser coil. If that happens the compressor amps will go up considerably and you could damage the compressor. I have seen air restrictions do some bad things to air conditioners.

I think very few air conditioners ever actually wear out due to excessive use, most failures occur due to lack of use.

That's a concern of mine; that the warm exhaust air will be slightly contained under the tarp. I'm trying to come up with a sort of cage that will tent the tarp over that section.
It gets very warm and humid down here and I'm not inclined to place a window unit into the home, but that's an option, too.

Thinking about it, I have a device that measures amps being drawn. I can hook that up to SP both before and during the test, and see whether there's a spike.

Thanks for the warning.
