Rooftop a/c info needed for my daycab.

A thought, you said compressor changed 2x, did you change accumulator (drier) and the orifice tube at the same time?

 

Going to be hard to put a room on a fiberglass roof.
I don’t think a 5000 btu unit will cot it.

 

Accumulator and orifice tube should be changed every time you change a compressor, and type of compressor death dictates what else needs done.

If you have an older truck (10+ years) i would suggest replacing EVERYTHING. includes hoses, coils etc. 2k for parts alone is steep, but sounds like dealer prices, pretty sure i could do it myself for 2k including extra tools to remake all the hoses and the 134a

 

I already have a fantastic fan up there and you cant even really notice it, you have to really look at it to realize it is there, the dometic takes up even less room and is more low profile than the fantastic fan

 

Ask and ye’ shall receive.



Was just reading this thread and this dude was pulling in. What timing. Haha.

 

You can’t even really notice it.

 

Sounds to me like when replacing the AC compressor you are not flushing the lines, dryer etc, also its worth replacing condenser and evaporator, surely it's easier to fix these things?

An AC system isn't that complicated, Evaporator condenser blower compressor tx valve dryer and some lines.

Replacing it all would be cheaper and geta better result than a ####ty caravan one which is designed to be running whilst bumping along down the road.

I just did an international eagle and I think it was about 2k to replace it all and regas

Just my two cents

 

I was thinking this same thing. I can’t help but think there is debris in the components that’s plugging up orifices and passages and that’s causing restrictions keeping the refrigerant/oil from properly circulating, then, causing the compressor to self-destruct.
