Multiple refrigerant leaks and workmanship responsibility after installation of a customer-supplied compressor on a Tesla

Sifu White explains what happened

If a workshop is uncomfortable installing a customer-supplied part, it is better not to accept the job. The owner first contacted Sifu White about two months earlier. The compressor was noisy and the air-conditioning was weak and intermittent. Inspection found a failed compressor. The customer considered the quotation expensive and bought a part from China. After it was installed elsewhere, the system developed a refrigerant leak.

Sifu White does not accept installation jobs involving customer-supplied parts, so the work was done elsewhere. Refrigerant leaks remained afterward. According to the customer, one refill lasted about two weeks and another only around one day. When we opened and rechecked the system, we found many leak points at several connections and gaps, with the strongest leak around the condenser near the piping.

On closer inspection, oil had flowed down from above, and the middle section also had a problem. The earlier compressor failure may have contributed as well. That is why Sifu often says that a workshop should decline the job if it is uncomfortable with a customer-supplied part. If it accepts the work, installation must be done correctly. In a case like this, the cause must be distinguished between a product defect and workmanship.

In Sifu White's opinion, installation is the more likely cause in this case because the workmanship appears careless. A final conclusion should still be based on inspection.

Why cooling after a regas does not prove a repair

Refrigerant circulates through a closed circuit; it is not fuel that the engine consumes. If cooling returns after charging and then deteriorates, the investigation should establish whether there is a leak, whether the previous charge matched the specification, and whether another control or heat-rejection problem is present. The initial return of cold air describes performance at that moment. It does not show that a leaking component has been repaired.

A model’s familiar failure pattern is a starting point, not proof. The condenser, connections, hoses, compressor seals and evaporator inside the cabin are different possible inspection locations. An oil stain can guide a leak test, but it is not a substitute for confirmation. Finding one leak also does not clear every other part of the circuit. After repair, the sealing and cooling performance need to be checked again under conditions relevant to the original complaint.

What to compare before repairing or replacing a part

A similar shape, a logo or a seller’s use of “original”, “OEM” or “recon” does not establish suitability on its own. Model, year, engine configuration, part number and connections need matching. Supply traceability, actual condition and warranty terms are separate checks. New components still need inspection before and after installation, while used components need particular attention to their history and the basis on which they have been tested.

The value of a component repair also depends on the assembly’s internal condition and the availability of suitable repair parts. An external clutch fault can require a different solution from internal wear or contamination. Compare labour, related system work, the possibility of having to dismantle the assembly again and written coverage as well as the part price. Prices, turnaround times and warranties mentioned in a historical video do not automatically apply to another vehicle.

What to tell the workshop about your own car

You do not need to guess a part name first. A clear description of what actually happens is often more useful for reproducing the complaint than requesting a particular replacement.

• Record the last regas date and how long cooling lasted.
• Bring earlier quotations, part numbers and warranty records.
• Include the model, year, recent repairs and what changed before or after the symptom began.
