I've been toying with the idea of getting an EPA sec609 License so I can fix my AC in my garage and actually purchase refrigerant other than R-134a. I've been looking over the study guide, and although it looks like it will take a little more than causual studing, I think I could pass the test. Let me know if you think I'm dreaming, and shouldn't waste my time.
If I'm going to use a license to purchase the refrigerant, I'm going to have to comply with the law in it's use. I have a set of R-134a gauges, the cheap Interdynamics kit, a venturi vacuum pump and 2hp compressor (I know probably not good enough), plus I can rent a vacuum pump cheap, but I worry about the proper recovery of refrigerant in my car?
What is the cheapest legal method of recovering that refrigerant and then turning it in to get it off my hands? The last thing I want to risk is a $25,000 fine from the epa because I didn't use certified equipment in recovering refrigerant in my garage.
Is it legal and meets EPA rules to connect a manifold and line to an evacuated propane tank in ice water? I think the EPA rule is that you have to pull a 5" vacuum on the system to recover the refrigerant properly? Can this be done with the tank in ice water? If not, what about refrigerator compressor from salvage yard? Will this violate EPA laws or regs that could result in fines?
