Cruiseair review – one not working
-
Hvac guy is coming saturday. He said he has new valves some of mine are frozen and I want to zero out the system where everything works. Goal is to replace broken valves, take the r22 out and put 1.6 lbs of r22 back in.
-
Does the amount of R22 on the Cruisair label take into account the different lengths of copper lines for each unit? Or does that not make any difference?
-
The label only takes into account the unit itself and does not take into consideration the copper.
I’ve been doing my own A/C work on these units. Had multiple LO PS on bedroom unit. Thought it was low on R-22. Charged it and it went away. Recently went into the unit (took cover off) and was checking caps etc. Funny thing is, the LO PS started to return randomly. Come to find out, the low pressure switch connections that go from the board to the remote control board was loose. I had a meter on the actual pressure switch and it was fine. So, I actually charged it for no reason few months ago. A lot of this is trial and error IMO. It seems the “subcool” app numbers for charging do not work for these units. It had me remove or add when things were already perfect.
I do have one unit that has low head pressure for some reason. About 110 PSI running. I believe the valves on the compressor are bad, but haven’t confirmed. Without a pump down option, not sure how to test it.. Perhaps maybe block the condenser coils off with something like cardboard. Bought a filter dryer already JIC I do the compressor swap, if I can find one to replace the original one. Hard to find a 12-13k BTU 115v R22 unit these days.
I’ve heard of others suggesting that AAP told them to take out the HGB but not sure if removing that will drain all R22 or if there is a schrader valve it connects up to.
Very glad that AquaAir is coming out with a drop in as it does make me breathe easier JIC something totally goes wrong with one or more of these units. I’m currently in Texas and with only 3 running, it’s very hard to keep the bus cool in only 85 degree weather.

We’re TX based an have 3 CAs in our 1996 Liberty 40′ XL.
The following threads are some of how we’ve managed our CAs and heat for the last 9+ yrs.

Hidden 75,
If you are only seeking a replacement compressor at this time, this is it. Also, go by superheat, not supercooling for CruiseAir units.
Note: the below compressor, a direct fit, is 12K BTU vs the 14K BTU in original and now unavailable compressor. Consequently, it will draw approx 2 less amps

Can you explain how superheat indicates correct charge level? I thought these had expansion valve which controls superheat if yhave minimum amount but not affected by overcharge.
-
Hello John – CA units have capillary tube metering, therefore, superheat. (expansion valve = subcooling)

Thanks for the information. I should of been more specific. I’ve been using the “superheat” method for charge. The “app” name is “Supercool” (sorry I thought it was Subcool) or something like that, but it does fixed orifice or TXV calculations for you. I’ve been using fixed orifice for all my charging.
I think the thing that throw stuff off is the de-superheat (HGB) valve. I’m not 100% sure my issue right now is the compressor, but sure seems like it.
I’ve looked at this compressor in the past but didn’t pull the trigger until I was more positive it was my issue. I guess it couldn’t hurt to pick one up anyway if I can prolong replacement of a complete unit down the road by having a spare.

My hvac guy has vacuumed out all the units. The unit that was not working had loose connections on the compressor. He has 2 new valves to install and I think he wants to install dryers onto the system.

Driers would be great!
FYI….any drier MUST be bi-directional in flow (bi-flow).
Liberty Coach in Stuart, Florida uses DANFOSS Part # 023z1402 as seen in the photograph.
-
Just confirmed they are bi-flow dryers.
-
Are those $8000+ units that are the replacements for Cruisair’s ready to go?
-
I dont think so
