Normal Lifespan of A/C Units?

Have 2 Carrier AC's on my 5er that are 8 yrs old and never had an issue..Carrier doesn't make these AC's for 5er's anymore, so if something does go wrong and I can't find parts, may need to go to a different manufacturer.

But to OP, no it's not normal for AC's to last no longer than your's did.

we've had to replace both the bedroom 15K Penguin and the living area 15K Dometic AC's on our '06 SunnyBrook .... from what I've seen, the lifespan of a RV AC/Heat Pump can vary widely .... when used at the beach (salt air) can take one out in 3 +/- years .... use under other conditions can result in a much longer life

Same here, AC on all our RVs have worked well until we sold them. Current rig has 7 years of heavy use, but we constantly monitor AC voltage drop which can severely limit the lifespan of an AC unit. I would think it uncommon that both AC units would have the same fate this early on and within months of each other.

I would start monitoring your AC voltage. Running them at less than 108 V will shorten their life. Mine are at 10 years and see no reason why they will not go another 10. I recently had a fan that was dragging but was able to raise one motor mount so it now turns freely.

Mine's still running fine - from 91. Like most things stuff happens - when your talking air conditioners lots of small/inexpensive stuff can impact whether they work right (thermostat, fan motor, capacitor etc) and "die" usually means something expensive like compressor or freon leak. What happened to yours?

Running AC on low current is one method that results in premature death - always good to keep an eye on voltage when running your air conditioner.

The AC on my fiver has been working for 14 years now. I keep my fingers crossed as it really gets a workout in the summer.

Quite odd I'd say.

No....

We've received over 10 years on each of our A/C units that ended up needing to be replaced. We had one last 16 years and was still working when we sold the TT.

Maybe due to an electrical issue. Power spike or low power at campground(s) That's why many RV'ers use power conditioners.
