hire a EPA certified HVAC technician. federal law requires anyone handling refrigerants to be EPA certified.
R-12 for cars and trucks............. EPA 608 certified for homes.... This is a certification that is required by the EPA, and if you are to handle any kind of refrigerant you must be certified..............
I was certified back in 1992 as a universal level. How do I replace the card?
Have an ASE certified technician in an EPA certified service shop do it. This task involves recovery and storage of the refrigerant in the system - purging the system in a manner which releases it into the atmosphere is illegal under federal law. Then the accumulator can be removed. If you remove the accumulator, you'll need to replace it.
Just depends on age of the vehicle. EPA can certify some, but most conversion are not EPA certified. But the EPA will tell you that ONLY their kits can be used. I learned a lot from SkyCNG.
no they do not meet dot standards. and they are not EPA certified
The EPA's Clean Air Act Section 609
there are machines made specifically for recovering refrigerant. they are sold by HVAC wholesale distributors to contractors. federal law says that anyone handling refrigerant must be EPA certified. Contractors are the only ones who are certified because they take the required tests at wholesale distributor locations, as well as at industry associations or organizations. So, unless you are EPA certified....
You don't. You have an EPA certified shop which has the equipment to properly recover, store, and recycle the refrigerant do it.
I would go to the EPA's website and see which location of a certified school would be best for you. They provide locations and certified training schools.
You have it done at an EPA certified shop. Doing it any other way is illegal under federal law.
