air cond run time

It is just a machine. Does not get tired like a person will. 24/7/365 is fine.

Bought a replacement unit for TT in June 2012 in Corpus Christi. Location had afternoon shade. I also used a dehumidifier and a fan in the 35' TT.

Ran pretty well nonstop eleven months of 12, 13 and died in August of 2014.

About 30 months of use. And I should note that park power was often under strain.

Got my money's worth from an RV appliance.

I've run our's for three weeks straight while in South Carolina in the summer a few years back.

Agree with Deltabravo and they run constantley for weeks. My ran from June 1 to
Sept 30 in Yuma at 120 degrees. Never got abv 80 inside which was comfortable because I worked outside.

Most components in our RV's are not designed for heavy duty day after day, week after week, month after month use. People who decide to stay south twelve months a year soon discover this. What works great for a few weekends a summer may not do as well long term. If the OP is only asking about running it constantly for a weekend, no problem.

Can you cite anything to support this statement?

The only thing it will hurt is your wallet when you get the electric bill!!!!!!!!

Hi,

Run it as long as you want. But watch the voltage sag. My personal comfort zone is no lower than 107 volts. I'm having to use extraordinary measures to get there this summer.

Agreed. I have a small volt meter I plug into a camper outlet to keep a eye on voltages.

I've run mine up to 3 weeks continuously multiple times. Never had any problems with it.

I run mine 7 days straight many times.

BNSF uses the same A/C units on their locomotives, for the cab. I am betting they run several days straight on occassion, without issue.

I've run mine 12-14 hours straight, no problems.
