We never use stop-leak additives. They contaminate the refrigerant circuit and can block the expansion valve, turning a minor repair into a major one. Every leak we find is repaired with the correct part.

What the Service Involves
The procedure begins with connecting to the vehicle's HVAC module to read fault codes — a step that most general shops skip entirely. These codes can identify failed sensors, actuators, and control circuits that would be invisible to a technician using only mechanical gauges.
We then perform a full pressure test on the refrigerant circuit, test every electrical component in the AC system, and measure vent temperatures across all zones. We do not consider the diagnostic complete until we have identified the root cause, not just the symptom.
Why This Matters for Your Vehicle
The cost of a proper repair is always less than the cost of the secondary damage that results from ignoring the problem.
We have seen vehicles where a $200 repair was delayed until it became a $1,400 system overhaul. We have seen compressors that failed because a $150 O-ring leak was not repaired for two summers. We have seen evaporators that required replacement because a cabin air filter was not changed on schedule.
Early diagnosis and repair is the most economical approach to maintaining your vehicle's climate system.
Timeline and What to Expect
We schedule services as dedicated appointments to ensure the vehicle receives the full attention the repair requires.
After completing the service, we perform a post-repair verification: pressure test to confirm no leaks at new connections, system evacuation to 500 microns, recharge to the manufacturer's specification by weight, and vent temperature verification.
Total time from arrival to collection is typically 90 minutes for straightforward repairs and three to six hours for major component replacements.
Cost Context
The cost of leak detection varies depending on the nature and severity of the fault. We provide a written estimate before beginning any work. Our diagnostic fee is applied to the cost of any repair we perform, so you are not paying twice for the same visit.
Serving San Marcos Vehicle Owners
We have performed leak detection services on hundreds of luxury and EV vehicles in the San Marcos area. Our experience with the specific fault patterns of the San Marcos climate means we can often identify the root cause more quickly than a shop without this local knowledge.
Why Choose a Specialist in San Marcos?
Most general auto repair shops are equipped to handle common vehicles with standard AC systems. Your BMW, Mercedes-Benz, Audi, Lexus, Range Rover, Tesla, or Rivian is not a standard vehicle.
It uses R-1234yf refrigerant that requires certified handling equipment, a compressor oil specification that varies by model and year, and in the case of electric vehicles, a thermal management architecture integrated with the battery system.
We work exclusively on automotive climate control. When you bring your vehicle to us, you get the full attention of a team that has chosen to specialise in exactly this work.
We provide a written estimate before beginning any repair. Our diagnostic fee is applied to the cost of any repair we perform. We do not begin any work until you have reviewed and approved the estimate.
Transparency in the repair process is how we build the long-term relationships that define our business in San Marcos. Call (737) 214-4410 to schedule your ac leak detection service. Same-day appointments are available in most cases.
We serve San Marcos and all surrounding communities in TX. Whether you are in the city centre or one of the surrounding suburbs, we can typically schedule a same-day or next-day appointment during peak AC season.
Our goal is to have your vehicle back on the road, fully cooled, as quickly as possible — without cutting corners on the quality of the repair.
