Running A/C on 110

[321Eagle]

We have a 247BH and while at home have it plugged into a 110 outlet to keep the battery charged and run basic lights/ etc. Was curious if that is sufficient and/ or safe to run the A/C unit. Daughter turned it on the other day and it did kick on we shut if off right away just because didn't want to cause any damage. Hoping for some confirmation or advise. Thanks

As long as there is sufficient power to start the unit, it is pretty unlikely you would damage it by running it on your home outlet. We've done the same for years. The moment of truth is start-up, that's when the AC uses the most power. If it gets past that initial surge, then it will use less power going forward. You may not be able to use much else on the circuits in the coach while the AC is running. Worst case you'll blow a fuse (trip your breaker).

BTW, welcome to the forum.

Your air conditioner always runs on 120V. The amperage of the service is what determines if it’s safe or will run. A household outlet is typically 15A, while your rig is designed for 30A service. It’s fine on 15A service as long as it starts and the voltage inside the trailer doesn’t drop too much while it’s running.

Depending on your property, you may be able to install RV service where you park and make things more convenient.

I run my AC off a dogbone connector to the 15A service on the side of my house all the time. It works great. If you run the AC, I'd suggest not running hair dryers, microwave, electric water heater, etc just to be on the safe side, but a standard 15A outlet works great, provided you're not pushing it through a lightweight 150' extension cord.

My Coleman Mach AC unit draws 10.2A, well within a standard 15A wall plug. I would guess the wifey’s hair dryer pulls just as much if not more than your AC. Go for it and keep the air in that RV cool and mild.

Thank you all for all the replies and assuring it should be fine.

I’ve never had trouble running a single A/C on a 15-amp circuit. Lowest voltage I’ve seen was on a 30-amp circuit at a campground. It’s much better at home.

Trailer Life Did a great write up years ago, on low voltage and AC operation..... Anything less than 108 volts is not good for an AC... It will run fine on less voltage, but it's not good for the compressor... get a volt meter to monitor volts..

Amazon sells a nice little AC voltmeter that just plugs into an outlet. As long as the AC doesn’t struggle to start and the line voltage stays above 110 it will be fine…. until you decide to run the microwave or some other large consumer.
Low voltage is very hard on lots of equipment, especially an air conditioner

Using a large enough power cord is important... you can burn up the wiring in the AC otherwise. Did that once.
