Mini-split two heads and Transformer

[eagle19952]

so...how many evaporator units/heads will one compressor unit run...?

I must still be on the ignore list...
or my question is to stupid.

   Not stupid BUT the answer is readily available here:

Have a look at the following. It should give you a good idea:

Google is great if you know what you are looking for.
the link explains it.
the base compressor unit with the most capacity can run 3 zones with up to 8 evaporators, apparently limited to 4T. or the equivalent of 4 average roof units.
prettty simple answer.
thanks.

Sounds good but if something happens to the condenser with 1 compressor you are dead in the water.AC units never quit unless you are using it, no redundancy that why the big boys stay with roof tops or 2 basement airs, 5 roof tops on a 2 mil coach are common and will be for a long time IMO

  I would think that since mini-splits are mainstream and made by all the major manufacturers, it might be easier/faster to R&R them than a rooftop unit. If you are worried about a failure, rather than having a built-in redundant condenser, you could carry around a portable 12KBTU unit....OR just stop by any Lowes/HD/Walmart/Etc. and pick one up to use until you can get your system fixed. Ideas?

LOL 102F golfing weather for Az it's 113F here   but it is a dry heat like a hair dryer with the breeze,headed for Idaho where I may need heat in the mornings.I really believe the mini splits would be fine if parked all the time but we move and very seldom are connected to a pole.The AZ heat will give a generator and AC units a work out for sure

Having a plan B for cooling is very wise, you can not depend on just one unit to be infallible. I have a 3 ton central air that works great, but I will also add roof airs as backup, and for campgrounds that do not have 50 Amp hookups. Roof airs can be taken off and changed in not much time, and it might cost less than servicing a big unit. Do what the big boys and NASA does; have backups.

3T basement here too.

if it got real rough a week in a hotel would be a vacation. so that $500.00 would be well spent waiting on repairs.
my unit by FirstCO out of Dallas TX has been in service since 1990.

since 2004 i have replaced the compressor in 2011 and the condenser fan motor in 2008 because they died and the A coil in 2013 because the condensate pan rusted out.

     That's really good service, Don.  What brand is it?  Is it an RV model or a household/commercial unit?  Any idea of the current draw and is it 120V? Are parts available OK?   Do you have ducts to distribute the cool air?
     Thanks,  BH

IMHO, better than lugging around roof ACs that would rarely be used

the brand is http://www.firstco.com/

220v. is what makes it durable but not popular.

and the newer units have bladed fans vs. squirrel cage hence a different installation dimension.
mine is an all electric coach 12kw (maybe 15kw) with electric heat.
ps it was desighned for commercial use on multi storry condo's

the air handler is vertical in a  closet in the coach, it is 20"x20"x30" approx. and the roof wall curve is integrated into/as the duct. it runs behind cabinets..

I have considered the many portable units that are out there for the bus and my cabin cruiser, but one problem is the floor space they take up, and the problem of spreading the air around from one discharge point. The bigger units are about the same price as the roof-tops. The smallest portable units have a square footage of 1.75 - 2.0. They do have the advantage of being more portable than a roof-top by a good margin. If someone has the space for them, they might work well. Some of them even have heat strips. I have three spare roof-tops, but they stay on the shelf in the garage until they are needed.

Interesting. I'm pretty sure that I can fit three cassettes in my existing ceiling channel. For me, the question will be where to put the condenser making sure that it has adequate air flow. I would prefer to put behind the tag on the passenger side of the coach. Currently, there is a house battery box there which might be moved and replaced with AGMs which would allow more flexible battery placement.
