1066 Air condtion

To make a long story short, either way you will be spending a fair amount of money no matter what direction you go. But for reliability reasons and performance reasons, I would stay away from tying to use a DC power inverter and running a small hermetic compressor on a 120V A/C system. By the time you obtain all the necessary parts you will still have a unit that is not meant to handle the vibration common in field equipment.

I've done many installs on everything from mining equipment to heavy ag equipment...and the most reliable system is still a PROPERLY installed engine driven compressor type system.

You will probably notice that your liquid and suction lines run up one of the vertical posts on your cab...this is the most common place they will leak...along with behind the compressor clutch. Check these out first.

Sorry for the long post, but it's better to fix it right the first time than to spend your money twice. And I've seen it done pleny of times.

Shoot me an email if you have anymore questions!

The actual component change out typically doesn't take that long, but sometimes to fish the new hoses up the cab supports can be quite an undertaking. It also pays to spend a half hour looming some of the hoses at potential rub points to avoid future leaks. After that it's just a leak check, a good hour on the vacuum pump, then it's time to charge it with refrigerant and a good run check.

It sounds like a lot of money, but properly done it will give you years and years of dependable service.

If you decide to go this particular route, I would stay away from the ag dealerships or automotive guys. In most cases, these are guys that are trained and certified to repair A/C systems, but most of their time is spent fixing other pieces of equipment. I would recommend talking to a Thermo King or Carrier Transicold shop. They do a lot of truck refrigeration and know the nuances of these type of heavy service air conditioners...and in most cases have the same labor rates as the ag dealers or automotive shops.

Good luck! If you have any questions feel free to shoot me an email.

Are there DC to AC converters nowadays that actually work?

Back when I was with GM, people would put those things on their vehicles and they would eat alternators faster than ya could put 'em on.
