What does a shop need to start servicing R-1234yf A/C systems?
Short answer: At minimum, EPA Section 609 certified technicians, a recovery and recharge machine or equipment certified for R-1234yf, matching hoses and couplers, a scale, a vacuum pump suited to the refrigerant, and leak detection equipment.
R-1234yf uses different service fittings from R-134a and is classified as mildly flammable, so equipment must be designed for it. Many shops choose a dedicated recover, recycle and recharge machine with a built-in refrigerant identifier because it automates much of the process.
Smaller shops with low volume sometimes start with manifold gauges, hoses and couplers for R-1234yf, a vacuum pump rated for the refrigerant, a recovery cylinder, a scale and a leak detector, then upgrade as demand grows. Recovery still requires certified equipment, so check what the regulations require for your setup.
Train technicians on R-1234yf handling, including ventilation and keeping ignition sources away. Label equipment so it is not used for the wrong refrigerant. Check the cost and availability of refrigerant in your area, and plan how you will handle contaminated refrigerant.
