In need of crusair repair in San Antonio
-
Thanks Jack for the tip. Just got in from a trip seeing the Granddaughter last night in coach and gonna check front ac with the tip you gave. It needs charging as it was blowing warmer than the other 2 up there the last couple days. They all worked up there but heading down to the Gulfcoast (Rockport Tx.) Friday for a few days and probably will need good cooling on the beach. Is there a temp you look for or just get it the coldest you can. I now you can overcharge them. Thanks again Folks.
-
If you use Jack’s method you will not overcharge because when you have the correct charge the suction line temp will be as low as it is going to get. If you continue to add R-22 it will start to go up in temp. You have to let the R-22 in slowly and give the unit a chance to get all temps stabilized before dumping in more. An ounce or two at a time.
-
I have seen temperatures below 32 and above 40,it takes time but it will work so much better,also verify that the condenser is clean when you work on it.If you don’t have the ability to actually measure the temperature just put your hand around the suction line and when it gets beer cold that will be close.

Thanks guys, going out now to check.

Cruiair Distributor A.E.R. Marine Supply recommended a local company, A & E Heating and Cooling to work on my units. They are coming to me. Appointment is on May 27th. I’ve made access for their tech.

Wow Don, do you have to pull that tank every time to check that cruisair? Is that a water tank? Where are the other ones.
If they don’t show, buy you a bottle of 22 and I’ll show you how to hook up and check using gauges and the cruisair chart. Hard to find somebody to work on these around here and have had to learn on mine with an expert (Justin Griffith, Granger Tx.) showing me how.
-
It’s scarey how easy it is to pull out that 100+ gal fresh water tank. 5 screws and 2 hose clamps. When I put it back together I’m gonna add some metal straps over it and blocks of wood at its base to hold it in place better.
The coach was built for dry camping. Remember(see signature) it is a 40 footer with OTR air so it lacks basement space. The original owner wanted extra large tanks.
The other tanks are in the 4th bays.

Thanks Glens:
If I have a problem I’ll take you up on your offer.Your(Muldoon,TX) not very far from us(Bulverde,TX), and neither is Justin Griffin(Granger,TX).
I do all my own R134a system work. But the Cruisair R22 fittings are different? Do I need adapter fittings? Are they the same as R12 fittings? I do have R12 adapters for my R134 gauges. I can by a 30 Lb container of R22 locally on craigslist fo $200 but I would prefer to buy R22 in a container smaller than 30 Lbs, but I don’t think its sold in smaller containers?
-
You need R22 gauges which are also good for R12 and 502,the good ones are from Yellow Jacket and around $100,cheaper ones are around $60,or you can find them on CL.
-
You can get the adapters at napa or did at my La Grange Tx. store. They are the same as your home ac unit. I just bought new 6 foot hoses for mine as the units are under the front bumper area on mine. Justin is the go to guy of all systems ac and electricial. He owns have the downtown of Granger which has curtailed his coach work. If you need his number holler. He showed me just enough to be dangerous. Buying that 22 in 30 lb’ers is best cause it doesn’t go bad and who knows when they will quit selling it. Keep a bottle under mine with gauges just in case somebody needs a shot. Think I got my leaks stopped or at least curtailed with Clifford’s advice on leaking King Valves. Tightened um and been holding for a month know. Good luck.

The short story is: a tech showed up, fixed the 2 inop Cruisairs, and they’re all blowing cold now.
The long story is: the aft system was low on R22 so some was added. The sight glass is clear now(no bubbles). The wx here was 82 degrees, 90+ % humidity, light wind, full shade. In the end the pressure/temp #s on the techs gauges were:low side=68 psi, hi side=248 psi, suction temp=40 F, discharge=117 F.
The fwd system had a bad run capacitor. Grainger has them for $25. But the tech replaced it with one he had on his truck. Nothing else was needed on this unit.
The port system needed nothing.
I fired up all three Cruisairs. Inside coach temp was 80 F. Within 20 mins inside coach temps(fwd, mid, aft) was down to 72 F. Temp differentials were all 19 degrees or greater. Within and hr they were all cycling on and off at 70 F witch I had set on the SMX II controls.
I’m HAPPY, HAPPY, HAPPY except for the $330 I was charged. Remember I’m a DIYer. It pains me to have to pay someone to work on my toys.
The tech was Brent Flower with A & E Air Conditioning, N. San Antonio area(Bulverde), 830-980-8600 http://www.ae4cool.com. All work was done in my covered carport.

If you think of the money you spent as tuition it will take a little of the sting out of the repair cost. Next time you will be more confident in pursuing the issues yourself.

You are correct Jon. Now I need to decide if I want to spend the $ on a good set of gauges and a bottle of R22.
To add to my last post: the Cruisair condensing units on my coach were manufactured by 3 different companies, Dometic, Taylor Made Environmental, and Marine Development. Each holds roughly 1.5 Lbs of R22.
The suction and discharge lines have service ports with whats called a King valve. There should be a brass caps on the fittings where the tech hooks the service gauges. Mine were aluminum so we changed them. The King valves have caps that should have o-rings. Mine didn’t so we installed them. For normal operation the King valves are open CCW which is called backseated. To service the system they are opened a couple of turns CW. If you were removing the condensing unit or evaperator from the coach for some reason you would close the King valves completely by turning them fully CW.
The Grainger item# for the compressor “run” capacitor is “30D520”, $22, for the “start” capacitor is “6FLU5”, $15.
Hope this helps

I havn’t heard the term “Beer Cold” since Lester worked on Mango Mike’s Liberty at POG 1 rally in Polk City Flordia back in 06.
The term Jack used is evidence that he has a degree in Charging Curise Airs.
