Signs Your Vehicle Needs This Service

  • Air from the vents is cool but not cold enough even on maximum AC setting, indicating refrigerant charge has dropped below the level needed to achieve designed cooling capacity
  • AC that cools normally when first started but gradually becomes warmer as the vehicle sits in traffic or ambient temperature rises, pointing to a marginally undercharged system
  • AC system that was recently inspected and confirmed leak-free but has not been recharged since a previous leak repair was completed
  • AC system that was evacuated for another repair, since any repair that opens the refrigerant circuit requires full evacuation and recharge after the repair is completed
  • No record of AC refrigerant service on a high-mileage vehicle with gradually declining cooling performance over several years

Refrigerant Recharge

System Evacuation and Recovery

System Evacuation and Recovery

We recover all existing refrigerant from the system using certified recovery equipment. The recovered quantity is measured and recorded, and the difference from the specified charge confirms whether a leak must be addressed before recharging.

Leak Confirmation Prior to Recharge

Leak Confirmation Prior to Recharge

We confirm the system is not currently losing refrigerant before adding refrigerant. If the system shows evidence of an active leak, we address the leak repair before completing the recharge.

Deep System Vacuum

Deep System Vacuum

We pull a deep vacuum on the evacuated system to remove moisture from the refrigerant circuit before recharging. Moisture in an AC system converts to acid under operating conditions, which attacks seals, o-rings, and compressor components.

Precision Refrigerant Recharge

Precision Refrigerant Recharge

We recharge the system using the refrigerant type specified for your vehicle and the exact charge weight specified by the manufacturer. Correct refrigerant type and precise charge weight are essential for both cooling performance and component longevity.

Post-Recharge Performance Verification

Post-Recharge Performance Verification

After recharging, we measure vent temperature at the dashboard registers and confirm the system is achieving the cooling capacity expected for the current ambient temperature before returning the vehicle.

What to Expect: Typical Service Times

  • System evacuation and refrigerant recovery: 20 to 30 minutes
  • Leak confirmation check: 15 to 30 minutes
  • Deep vacuum pull: 30 to 45 minutes
  • Precision refrigerant recharge: 15 to 30 minutes
  • Post-recharge vent temperature verification: 15 to 20 minutes

How Our Technicians Approach a Refrigerant Recharge

When a vehicle comes in for a recharge, we begin by recovering the existing refrigerant and measuring the recovered quantity. If the recovered amount is significantly below the specified charge, we investigate whether the leak has already been repaired or whether a new leak search is needed before proceeding.

We pull the system into a deep vacuum for a minimum of 30 minutes to remove moisture. We then hold the vacuum and observe the gauge for any rise in pressure, which would indicate a leak in the system that would need to be addressed before charging.

We recharge the system using a certified refrigerant scale to ensure the correct weight is added rather than relying on pressure readings, which vary with temperature and ambient conditions. After completing the charge, we measure vent temperature under specific conditions to confirm the system is performing within its designed cooling capacity.

We document the refrigerant type used, the quantity added, and the post-charge vent temperature for your service record.
