Mini-Split Install

Is there any reason this won't work. I want to install the compressor against a side wall in the garage and vent it out the side of the bus. An details on why this wouldn't work?

It should work as long as you get the air flow through the coils

It'll have the whole garage to suck air across the coil and vent it out the side. I have no A/C in the garage, so when needed in the cabin I can open windows to ensure enough air. I talked with a couple HVAC guys and they agreed it would work fine.

With a few small mods this will work nicely.

As long as you've got decent ventilation in the garage, I don't see any reason not to

If the A/C is on it's because it is hot out. I don't have any A/C in the garage. So when the A/C is on, the windows in the garage will be open to ensure plenty of air flow. One HVAC guy said it would heat the air in the garage which is total BS. It sucks ambient air from the garage and vents hot air out the side, no hot air in the garage.

You will have the hot air from outside, which means you need to insulate your garage.

What about rain or intruders coming in the windows and compressor noise? The evaporator is quiet, but the condenser is louder. That may not matter to you, but noise level is a big part of why I chose mini splits.

IMO you would be better off skirt mounting the condenser and conserving your garage space for more important things.

1st off, there is no skirt mounting space to use. The compressor will suck the same air it would if it was completely outside the bus. The wall separating the cabin from the garage has 5" of rigid, the walls as well as the ceiling 1-1/2". The only thing not insulated is the floor. Intruders coming in my occupied bus?

You asked for feedback. Those are things I would consider.

There are many times I leave my AC running while Iím not in my bus, and when I and my family are sleeping it feels better to be able to lock up. I know windows can be broken, but it seems like leaving them open presents more of of an invitation. And rain can blow in fast and make a mess.

Iím sure youíll find something that works, but if the skirt is out of the question, why not build an enclosure that can vent with out relying on windows and interior air at all?

You could bring air up through the floor and vent out through the side like you proposed. The enclosure would deaden the noise some and eliminate the need to open the windows. Air from below the bus should be relatively cool which should improve your efficiency also.

Okay, you've got me thinking about it more. As much as I love the fit of the condenser in the garage, if it's going to be noisy and inefficient , it might be wise to consider a different location. I suppose if I route the exhaust out the divers side I can mount the condenser underskirt behind the rear wheel flap.
I need to wait for the rain to stop to get under there and check it out. I already cut off 2 of the mounting feet on the condenser, I'll need to weld them back on.
