I am thinking of spending summers in South Texas where the AC will be running almost constantly for three or four months. I wonder how long one will last? Mine is an almost brand new Coleman 13,500 unit.

They are nothing more than a cheap window unit, dressed in RV clothes and sold for 3 or 4x the normal price. I have found that 6 to 8 years of use in south Texas, SW AZ is about tops.

that's a tough one...you never really know. My front Dometic a/c is the original one and is a 2001 and still works great....capacitors replaced a couple of times and a new thermostat once. Rear one is 5 years old now.

The original Duo-Therm A/C's on the 20 year old Class A we sold last year were still working fine. I did replace the start/run capacitors on both with hard start caps a few years ago. The only other maintenance has been normal cleaning. The analog thermostats were replaced with digitals a couple of years ago, but that wasn't due to any failing on the part of the A/C's.

Both original A/C units on our 96 Southwind are working properly. But, I'm in the northeast so they don't get used as often as units farther south. |

Our 13.5 Duo Therm AC was still working fine after 10 years when we sold our old trailer to friends.

Howdy! Toss of a coin. I have one in a 1988 Air Stream that still going strong. My last 5er the main AC was still working 11 years after we purchased it and the bedroom AC had been replaced twice with 7 years of that fulltiming. "Hapy Trails" Chiefneon |

Both my 1984 Duo-Therms still work great. I don't know what the previous owner might have done, but they appear to be original.

As noted here they'll run a dozen years. Maybe 2 or 3 dozen years. Keeping filters and coils clean is important. And yes, you may need to replace capacitors Biggest factor I think of here is POWER. If voltage is around 120 and there are no spikes, outages and brownouts, you can expect those dozens of years.

I know that they will run many years in normal RV use, my concern is how long one will last in what amounts to darn near 100% duty cycle for months at a time.

In 1998 we purchased a 1966 Avion that was used for full time living. It had run in South Florida all those years. We revamped the entire trailer, used it as a weekend camper until 2004. When we sold it the A/C was still going strong. Our Rig: 2005 Dodge 3500 - Dually- Cummins 2006 Outback 27 RSDS We also have with us two rescue dogs. A Chihuahua mix & a Catahoula mix.

Mine was built in 96 and still running great. They can last a long time. Every once in a while you need to take a garden hose to it, and wash the outside coils. Once a year in most areas, twice if it is dusty in your area. Keep the inside coil clean - rinse out the indoor filter soon, and when about 1/2 way through summer. While you have the inside cover off, if you have not checked the inside bolts that hold the top unit to the inside frame, tighten them with a 1/2" or 9/16" socket. Just 'snug' not tight. It is compressing a gasket, and needs to be snug about every 3-4 years. Just slightly over finger tight. . . Good luck! Fred. |

I have one on my 1990 pop up that is original, main thing is cleaning the coils and the filters, plus correct voltage.

On our 1964 Airstream, lasted 45 years! Now, on our 1990 Bluebird, just replaced one of three. 25 years, and 2 of 3 still going. |

My question to all who answered the OP's question and swear the AC will last a lifetime is ...... Have you read where and how he plans to use his AC??? Read the original question, then post an answer based on his criteria.

One of our Dometic died after 11 years, the other is still going (knock on wood) and we live in Florida where we run the AC all year and we travel to LA and OK in the summer heat!

Our Phaeton's two Duo-therm heat pumps are working on 10 years of full time use for heating and cooling. The front unit has been replaced twice, with additional control boards and service. The rear heat pump has had one capacitor replaced and we've cleaned the compressor coils 2-3 times. We keep the front at about 75° during the day, 71° at night, the rear unit at 80° days, 73° at night.

An RV A/C unit is your basic "window A/C" used for years before "central air." Just rearranged for rooftop operation. Window units last a long time and so do RV units. As long as the campsite provides steady good voltage and amperage, and you keep the coils clean, you'll be OK...Really! One caution - If your South Texas site is on a beach, salt spray will rust/corrode everything. Your coach, your toad, your lawn chairs, your A/C, you name it. * This post was edited 04/26/15 05:37am by j-d * |

I've got these flimsy sponge like filters and know they don't really block out the dirt. I'm thinking there has to be a better filter. Any suggestions? tks

Read the original question, then post an answer based on his criteria. The Bluebird spent those years in TX, FL and GA, so it spent its life in the south. I do not know what percent of its time being used was in the summer, but I bet it got a lot of AC use in south TX and GA, and FL! I just got it a year ago. The one that failed, it was the board that failed, the AC itself worked by hot wiring it, and controlling with a switch! The board was obsolete, so replaced the whole thing. The other two OEM AC's are going good, knock on wood! I do not know the history on the Airstream, as to how much the AC was used. |

I wondered if they would have similar service lives to window units. |

AC units are NOT that complicated, whether they be Window/RV/Home units. The BIG difference between an RV and the others is, the RV unit rarely gets maintenance(filters cleaned the evap/condenser cleaned. They are subjected to varying 120 voltages (especially LOW voltages) and that causes excessive wear and tear on compressors and the capacitors. Then when they break, they are called junk. Running 24/7 in a hot climate probably equals 3 to 4 time the normal use in an RV, so you would expect them to wear out/fail quicker. I would expect that the OP's AC unit should last 5 to 8 years in the conditions he will put it in. Doug

I have a 2014 Bighorn with Dometic a/cs and spend the winter in Florida and the A/Cs run almost constantly. The 15K living room unit has been replaced 2 times. The original lasted about 1 year and the replacement lasted about 4 months. The 13.5K bedroom unit is still doing Okay. So I guess your longevity will depend on the manufacture. The Dometics are from China....
