Years ago I was going to fit an under dash ac in Lorry the Hino with 24v. It was a comprehensive kit that even you could crimp the fittings on at home. There was a place to mount the compressor on Lorry and the bracket supplied would fit right on. Sounds like yours will be like a retro fit so use the new compressor, condensor, drier and then the evaporator unit in the cab. Cost was not prohibitive back then so off the fleabay and search for a/c units.
At the same time I looked at those parking a/c units that are self contained and only need 12v/24v connection that sit on the roof but after chatting with the maker they said they are not to be used when driving but gave no reason as to why.

Under the dash units usually work really well

The only downside is with under dash is you can't mix with warm air to sort of take some of the chill off or send to demist

But a minor detail most of the time

The 12/24v power only are evaporative coolers, OK for sleepers sort of, a coolpack is miles ahead (a little diesel driven A/C), under dash are ok or a red dot on the roof is my pick, the one I have on the Louie is the ducks guts,

My White 7500 sleeper has a standard old style under dash unit fitted up with the roof console. Normal Sanden compressor. Works fine. Original owner has fitted one of those old dash fans hanging down to direct the air at the driver.

The "Red Dot" on the Atkinson certainly provides cold air, just not enough volume of air, and so i always end up with the window down anyhow.

Brett if you take of the outer cover then you should find a inner cover held down by two rubber straps that will give you access to the condenser coil it may need a clean,  it's alli so be gentle maybe soapy water, the water should drain away out the tube out the back, use a bit of air maybe but not direct on the coil you can damage the fins, one of my brothers put a bigger faster fan in out of something else, but I only believe half of what he tells me, if the coil is damaged and some of the fins are closed of the air con blokes have little combs to straiten them out, or maybe it just a hot truck
