Service Procedures

Essential R134a automotive A/C service steps:

1. Leak detection: Check system for leaks before service
2. Recovery: Reclaim existing refrigerant using R/R/R machine
3. Evacuation: Remove moisture and air with vacuum pump
4. Recharge: Add correct amount of R134a refrigerant
5. Performance test: Verify cooling performance and pressures

Commercial Refrigeration Applications

R134a is widely used in commercial refrigeration:

• Supermarket systems: Display cabinets and cold rooms
• Food service: Commercial kitchens and catering equipment
• Beverage cooling: Vending machines and dispensers
• Industrial processes: Process cooling and chiller systems

R134a Refrigerant Facts

• Chemical name: 1,1,1,2-Tetrafluoroethane
• ASHRAE number: R134a
• GWP: 1,430 (100-year horizon)
• ODP: 0 (zero ozone depletion)
• Flammability: Non-flammable (A1 classification)

R134a vs R1234yf (Automotive)

Important Notes

• Not compatible with R1234yf: Different fittings prevent cross-contamination
• Recovery required: R134a must be recovered, not vented to atmosphere
• Dedicated equipment: Use R134a-specific recovery machines
• Ongoing demand: Millions of R134a vehicles still require service
