Engine AC

I had my engine ac compressor replaced a couple of years ago.
I took it to a Cummins repair shop.  Now I find out that they really don't have the expertise in that area since AC is an add on.
I am just getting around to take it somewhere else. 
Does anyone know of a good repair shop between Ohio and Florida.  Preferably in one of those two states.
They checked for freon leaks.  It appears that the compressor is locked into place but I'm not sure.

Thanks

When home in the Dayton area, I take it to my local Goodyear dealer. They back me up to a bay and then work there.  It is just a standard auto AC system with more refrigerant because of the longer hoses.

The compressor is pretty easy to access.

A good automotive AC shop can diagnose the system, pull a vacuum, fill system, replace dryer, etc. They will ask about system capacity - tell them four to five pounds. It could be slightly more depending upon year and length of coach. You will need to demonstrate the proper use of safety stands if they need to get under coach. Can also be a problem if they are working on it outside the shop (doesn't fit) and it spends the night outside the security fencing. The area everyone will try to avoid includes air dampers, controls,  and evaporator in dash.  I've used Foretravel, a local heavy duty truck dealership and a local automotive shop that knows AC. Least favorable was truck dealership- expensive and refused to touch evaporator.

I installed a curtain rod behind the front seats and put a nice printed fabric shower curtain with white fabric liner on it. We pull it across when running dash AC - makes a big difference.

Most heavy duty truck shop will work on air condition. I had looked up on line in my area and found a mobile air condition repair man. He would go out to heavy equipment on site and repaired whatever had to be repaired charged a service call but charge the same rate as any shop. He came out to my Campground and done at nitrogen pressure test for me found the leak and then I repaired it myself. He came back and added the Freon. It took 80 ounces R134a since then I have purchased the equipment myself to vacuum and install the Freon since in the last three years, I've had to replace hoses, condensers and seals. Learn as you go along.
Rick & Hilda looking forward to full- timing one day for now couple of months at a time
