Hey everyone. I got a question. A guy at work said that if a guy bought one of those ac evacuator machines it would be a license to print money. I work for a large trucking company but we don't do ac recharge in our shop. I found a machine I'm looking at buying but I don't know what to charge...



Any advice?

Not being familiar with the business side of things I can't offer any advice on what to charge but I can offer some insight on AC service. When you refer to the AC evacuator machine, I assume you mean the full blown AC service cart that does the three basic functions of AC service: recovering refrigerant, evacuating, and recharging. The second stage, evacuation, is an essential part of AC service and involves connecting a vacuum pump to the AC system and removing air and moisture from the system. Trace amounts of air can cause excessive pressures and water can cause failure of compressors since it's not compressible. Evacuation is also important because it provides an opportunity to do a 5 minute vacuum leak test before you charge the system.



Other things to keep in mind: EPA requires that at least one person in the shop be certified. Mobile Air Conditioning Society (MACS) is one organization that provides certification. I've done this training and it is simple if you have schooling in AC service.



In addition to setting yourself up with a AC service cart, you'll also need some simple stuff like electronic leak detectors (gas sniffer), UV dye, and an easy means of injecting oil and dye in the system. I use one of Tracerline's leak detection kits.



A manifold guage set, and weight scale comes in handy if you have to go out in the field or equipment yard to service something. Hauling the big AC service carts around can be a pain.



If you're servicing trucks outside of your company, you might want to think about a refrigerant ID tool. Sometimes people put oddball refrigerants in their systems that can contaminate your R134a refrigerant and equipment. These tools are expensive though.



Stay cool.

Sounds like you're more interested in a get-rich-quick scheme than actually servicing A/C systems. Do the world a favor and stop right now. If you want to fix A/C, than learn how it all works, and act within proper legal and ethical boundaries.

The machines you're referring to are known as RRR machines, Recover, Recycle, and Recharge. They are geared towards dealerships or shops that can't be bothered to have the proper equipment. Seperate vacuum pumps, scales, gauges, etc are more accurate, and in the world of A/C, accuracy is everything, otherwise you're just emptying someone's wallet and flushing the bullsh*t down the line for someone else to deal with.

Yes, I have strong opinions. No, I'm not afraid to voice them. Yes, there is money to be made in fixing A/C. No, it's not just as easy as buying a $xxxx.xx machine and charging $xxx.xx for a half-assed attempt at A/C service. Why? Because when you screw up, not if, but when, than ALL of us look like thieves and con-artists to vehicle and fleet owners everywhere. And if that isn't convincing enough, consider this: when refrigerant comes in contact with open flame, from say, a careless cigarette or a torch applied to a seized fitting, it has a tendency to become quite similar in molecular structure to the type of gas used to kill soldiers in WW1 trench warfare. You wanna mess around with mustard gas for a quick buck?

Please, educate yourself before making a mistake that can, at best, make you look bad, at worst it can kill you or others. MACS was mentioned, they're a great resource for A/C information.

It is nice to hear that other people are also interested in improving and upholding the reputation of the trade. Good on ya THATguy!
