I have a 2004 diesel pusher Motorhome, dash air is weak, and the schrader valves are leaking so I need to have it recovered so I can replace them and recharge the system.

Mobile would be easiest since parking is usually tight, but if you know a shop with large parking that would work too.

Thanks

I do not endorse this brand, but I use a similar, but pro-grade, tool on residential and commercial AC's to replace Schrader cores without having to evacuate the system. Then, you only have to top it off after replacing the valve cores.

This is just the first one I see on Amazon, to demonstrate the procedure and concept. Do your own research to determine if you want to do this and which products to buy. But if you know that all you need to do is valve cores, the tools will be cheaper than hiring someone else.

Amazing how many shops that work on vehicle A/Cs don't have or even seem to be aware of such a tool. Sad to think how many bazillions of dollars and pounds of refrigerant have been wasted by goofballs evacuating and recharging systems just to replace a shrader valve.

Here's a good video that shows how it works:
