Our 6 year old Coleman 1350 AC keeps tripping the breaker when the compressor kicks in. The RV shop said the compressor is going and that the life of an AC unit is 3-5 years.

Does this sound right? If so, should I replace with a 1500 unit? Will this cool better? If someone has replaced their ac, what was the cost? ( for reference).

Thanks,

I replaced my AC this spring. It was 20 years old. $600 and 2 hours of my labor.

Sure a 1500 will cool more than a 1350 by 9% or so.

Sounds like the RV shop is trying to sell you a new A/C. I've had several with 10+ years and run fine.

Is it tripping the breaker in your trailer, or on the pedestal?

I think I would add a hard start capacitor kit and see if that solves the problem. 3 to 5 years sounds way too early for an AC to go out. Mine is 25 years old and still works fine

It trips the breaker in the RV. It will run until the compressor kicks in and then the breaker trips. The breaker doesn’t seem weak (not soft or easily reset). RV shows 121-118V power while hooked up at home on 30amp connection.

The RV is plugged in and runs off and on at home too. We use it at home and the ac helps keep it dehumidified all the time (south FL ...hot and humid). So, 6 years constant use. I had to replace the fan motor once. I did that myself. It was a bearing issue in the fan motor.

Install a hard start capacitor. $15.00 from Amazon.

If it was run on low voltage it could need replaced. Low voltage will destroy a A/C unit.

One MachIII in my small trailer is 16 years old and still working fine.
One Mach III in my big trailer is now 10 years old and doing fine.

I would expect 20 years of life or more.

Life of AC may depend on how it was treated. My 91 is working fine ... I did add a hard start capacitor when it was about 18 years old. If AC is like most things - older units probably have greater life than newer units ... but I have never heard anyone say that life of newer units is 3-5 years. As others have said running AC on low voltage will create issues.
