It is the same basic unit used in portable offices and many mobile homes.

The residential guy that services my Trane had a look at the RV when it was sitting in my driveway and got glassy eyed when he saw the basement air unit sitting near the ground and easy to get to like it was.

Said it was easier than servicing many residential units.

Well, I called a place in Lodi that I have been to before and they still play with the basement A/C's. I really didn't want to go back there because two years back they convinced me to replace the circuit board and the thermostat which ran about $1000, and didn't do anything for the effectiveness of the A/C at that time.
I described what was happening with the amp draws and shut-offs and suggested they consider the capacitors and relays. What do you know, they concurred and are going to replace 4 capacitors and 2 relays. The parts were supposedly hard to find and may take as much as two weeks to get in. The job is estimated to cost me another $700
The fun never stops... But if I can get this coach to a proper point of functioning I may run across some of you folks out on the road....
I appreciate all of the responses....

The last time I bought a set of two caps with the hard starts the parts were about $50 from the local Winnebago dealer which is something they normally keep in stock since they are a common item to replace. It only takes about 15 minutes to replace them so even if they charge you $100 an hour for labor it should max cost $150 if they insist on a full hour minimum labor charge but many would only charge a more honest 1/2 hour or $100 parts and labor.

It is many times just the one on the main compressor that goes which will prevent the second compressor from starting as they are staged. I will switch the main compressor to the second ones start capacitor to get past this when it happens and then turn off the breaker to the second compressor so we have at least compressor #1 running. Did that in a parking lot while my wife called the next Winnebago dealer on our route to arrange a customer pickup at their parts counter the last time they went so we had house AC running to the dealer where we picked up the set of two capacitors and hard starts 30 minutes later. 45 minutes after that we were at our site and while dinner was cooking I replaced the capacitors myself and had the full system operational in plenty of time to cleanup for dinner. I also picked up a Hughes AutoFormer to prevent brownouts from overheating the hard starts again and have not had another failure in the years have have passed since then.

The handyman that visits the 1000 Trails in Clermont, FL services them as does Lazy Days in Sefner, FL and neither would charge $700 to install a set of start capacitors in a basement air unit. No second story work with everything on the ground and all is easy to get at with the only special tool being a broom handle to hold the louvered panel open while you replace the caps. All you need aside from the broom handle is a nut runner, pliers and a screw driver to do this very simple 15 minute task. It's not a job that requires the unit to be removed from the coach or working on your back in the dirt aside from possibly removing one sheet metal screw. You can do most of the job seated on a bucket or camp stool/armless chair.

Thanks Neil,

Perhaps I'll share your message with these guys.... And, perhaps I'll start turning a wrench myself and save a fortune...

You can take the capacitors and have them tested at any HVAC service company. At least they should be able to, when I was in the service business I carried a tester with me. If any of them are bad they should have them in stock or get them from a supply house. You can do the same with the relays they can match them or order them for you. If you do it yourself take pictures or mark the wires where the go. When working with the capacitors DO NOT TOUCH THE TERMINALS OR BARE CONNECTORS of the capacitors. The capacitors will have a charge in them. You can discharge them by shorting the terminals together with an insulated wire or insulated screwdriver. If your able to do it yourself you'll save a bunch of money. Make sure all power is turn off before working on the unit.

Update: I put my coach in the only shop I could find that would work on basement A/C systems. I told them that the second compressor draws 54 amps to try to start but then fails and the amperage returns to 15-17 amps, then, every 45 seconds or so the amp draw shoots up to 54 for a second and resets to 15-17. I thought the problem might be the capacitors or relays. They concurred and ordered the capacitors. Today I went to pick up the "all done" coach. Before leaving I fired up the generator and A/C - guess what..
The exact same things were occurring and the A/C was not putting out sufficient cooling. $536 for ?
I had a long chat with the tech who continually tried to convince me that the system is working properly. The service manager came out and heard me discussing these issues with the tech and agreed with me regarding why I thought the tech was wrong...
They are supposedly going to call Coleman in the morning and see if they can find a diagnosis for the problem.
DOES ANYBODY IN THE RV REPAIR FIELD NO WHAT THEY ARE DOING?????

They just concurred the capacitor was bad. I would test them before ordering parts.
Personally, it sounds like the compressor is locked up, but I won't tell you to order one because I haven't tested it.

There maybe a mechanical problem with the compressor. They could try a hard start kit, sometimes they work sometimes they don't. If the tech hasn't done it yet he should check that the compressor doesn't have an open start winding. To test the windings you use a omh meter and check the resistance of the motor windings. To do that with an omh meter you take readings between the common and start, common and run, run and start terminals. The next to the highest reading will be common to start, lowest common to run, highest reading will be run to start. The run to start will be the sum of the common to start and common to run added together. If it's not close there is a problem with the motor windings. He can also check if the motor is shorted to ground by checking between the terminals and the compressor case. I doubt if it's grounded to the case because that would be a dead short and trip the breaker. Good luck, sounds like the service manager knows more then the tech does. In the attached manual see pages 26 and 42 for an explanation of what I'm talking about.

As of this morning the service manager says that he spoke with Coleman and after describing the symptoms was told that my #2 compressor was overdrawing amperage and was failing. So, the service manager is putting together an estimate for replacing the #2 compressor.
My problem is, I have already replaced and updated the circuit board and thermostat, and have now replaced all capacitors and relays without solving the problem. Now they want to replace the compressor- why would I want to believe that they have finally diagnosed it correctly?

I'm in a horrible position because I cannot find anybody that is competent and available to work on this system.

Have they even tried doing the simple tests to determine if the compressor is actually defective?
It's same that other HVAC service businesses won't work on it. Guess as soon as they hear RV they think it's something special. But it's not, it's the same as any residential AC unit. It's also a same that most tech's have turned into parts changers. Just keep changing parts until it's finally fixed.
Problem is the more time they spend on it, the more it's going to cost you. If they are still available, wonder what a new basement unit would cost compared to your final cost. Sorry I can't help you more.
Just to give you an idea for the cost of a new 2 ton basement unit I found this on American RV's web site.

Simple test would be to switch capacitors with the other working compressor which can be done by just swapping a few wires with spade connectors on them. If compressor #1 now fails to start then they left the defective capacitor in place and possibly at best changed the hard start units (black plastic devices on top of the capacitors) however if compressor #1 runs after swapping capacitors and #2 continues to fail you probably do need a new compressor. From the long term use with a bad capacitor in place compressors do fail. Being that it was the #2 compressor the circuit breaker to that compressor could have been turned off to allow the rest of the system to run without destroying the #2 compressor.

I can't stand these guys that put on stupid. It is a very basic system mechanically with two run of the mill residential systems sandwiched into one box. Anyone who services mobile homes would be pretty familiar with the unit and a residential serviceman would have no problems if he was worth his pay.

Many times you are better off with a sole proprietor who does all the work himself then the big corporate run service companies.

Some do, but very few know anything about AC units.

The great thing about the basement air units is that any AC repair guy can work on them and they are usually cheaper than RV shops. the compressors and parts are found at local supply places (johnstone's for ex.). The trick is to "not" tell them it's an RV or to speak their lingo and tell them you have a 2 ton dual compressor Coleman unit not working. Before they come out prep the unit for them so it's partially slid out and tell them you will reinstall it. Never had a residential HVAC guy refuse to work on one this way.

White's RV service in Schenectady, NY has ordered a new basement air for our 2004 Vectra. He was surprised there was one available because Coleman doesn't make them anymore. He found a company that recently started making exact replacements for this basement unit. I don't know the company's name but when it is delivered I'll post back all the info I can on the replacement company.
Cost is $4k, Good Sam will pay $1,800 of that cost because that is what the repair would have cost. The unit is 10 years old and is corroded in many areas including really bad fins. Good Sam doesn't cover corrosion. We decided to go for the new unit because we plan on keeping this a long time and we are fulltimers.

I'll post all info in a week or 2 or 3 when it's all done. Luckily we are in place until Dec. 1st so we have plenty of time and no hot weather.

They are/have been the makers of Coleman-Mach basement AC units for decades and have always had replacement parts and whole units in stock if you need them. You can also get replacement parts at local HVAC stores like Johnstone's.
