I called numerous mechanical contractors before I finally found Advanced. None others,would work on my RV air conditioner, but Rob from Advanced did. I wanted it changed over to HCFC 134 an and he did so but then found out it was actually an R 22 system.At that point he dumped the 134 an and then charged it with R 22. At that point he dumped the 134 a and then charged it with our 22. He did not charge me for the 134 a.
I found Rob to be quite personable and he did a wonderful job.
