Visual & Component Inspection

Initial visual inspection of all A/C system components before electrical or pressure testing. Identify obvious defects before investing in pressure testing.

  • A/C compressor body and clutch assembly free of oil residue and damage?
  • Condenser fins clean and undamaged (less than 20% blockage or bent fins)?
  • All A/C hoses and lines free of cracks, chafing, oil stains, or damage?
  • Sight glass (if equipped) shows clear refrigerant flow with no bubbles at operating temp?
  • Receiver/drier or accumulator within service interval (replace when system opened)?
  • TXV or orifice tube accessible and no evidence of icing or frost?

A/C Performance & Temperature Test

Verify A/C system achieves target vent temperatures and adequate airflow at multiple fan speeds.

  • A/C compressor clutch engages when A/C requested (no cycling off immediately)?
  • Center vent temperature achieves target (45-50°F / 7-10°C at idle, 75°F / 24°C ambient)?
  • Blower motor operates correctly on all speeds (no dead speeds)?
  • All mode doors function correctly (vent, floor, defrost, recirculate)?
  • Condenser electric fan runs when A/C is active?
  • Evaporator drain tube clear - water draining from under vehicle when operating?

Manifold Gauge Pressure Readings

Measure and document high and low side pressures to diagnose charge level and system faults. Compare against OEM pressure charts for ambient temperature.

  • Low side pressure within normal range for ambient temperature (typically 25-45 PSI)?
  • High side pressure within normal range (typically 150-250 PSI at 75°F ambient)?
  • Static pressures equal after shutdown indicating no major restriction or leak?
  • Superheat (TXV systems) or subcooling calculated and within specification?

Refrigerant Leak Detection

Systematic leak detection at all A/C system joints and components. EPA regulations prohibit knowingly venting refrigerant.

  • Electronic leak detector used at all fittings, service ports, and component joints?
  • UV dye check performed (if dye previously injected) - no fluorescent traces found?
  • Schrader valve cores at service ports verified leak-free?
  • No active refrigerant leaks found - system confirms leak-free for recharge?

Refrigerant Recovery, Recharge & Compliance

Refrigerant service documentation per EPA Section 608/609 requirements. Technician must be EPA certified to purchase and handle refrigerant.

  • EPA-approved recovery/recycling machine used for any refrigerant removal?
  • Refrigerant charge weight documented (as-found and as-charged quantities in oz/g)?
  • Correct refrigerant type used matching vehicle specification (no cross-contamination)?
  • Refrigerant charged to OEM specified weight (from label under hood)?
  • Refrigerant service documented in shop records for EPA compliance?
  • Correct amount of PAG or POE refrigerant oil added per OEM specification?
  • A/C service tag applied noting refrigerant type, charge weight, and service date?

Post-Service Performance Verification

Verify A/C system performance after service to confirm adequate cooling.

  • Post-service center vent temperature achieves target specification?
  • Electronic leak check performed after service - no new leaks at disturbed fittings?
  • Compressor cycling at correct intervals (not short-cycling)?
  • Customer advised of findings, repairs performed, and future attention items?
