A/C Diagnosis and Repair in San Antonio

Weak airflow, warm air blowing, or an A/C system that cuts out on the hottest days—none of it works in Texas. Caleb’s Car Care, Mobile Diagnostics and Repair in San Antonio, brings on-site A/C diagnosis and repair so you can stay cool on the road.

Every job starts with diagnosis before repair. That means pinpointing the fault, explaining it clearly, and giving you repair options you can trust. All A/C repairs are backed by a 1-year parts & labor warranty.

FAQs

How long does an A/C diagnosis take?
Most diagnostic visits take 45–90 minutes. We test the system, check refrigerant pressures, and look for leaks before recommending repairs.

Do you recharge refrigerant on-site?
Yes. We use EPA-compliant equipment to recover, evacuate, and recharge refrigerant after confirming the system is sealed.

Can you fix electrical A/C problems too?
Yes. We test wiring, relays, sensors, and control modules with an ABS-capable scan tool to confirm electrical issues and make repairs where possible.

Is the diagnostic fee applied to repairs?
No. A/C diagnosis is billed separately at $150–$190 and is not credited toward repairs.

What if my A/C just needs a recharge?
We’ll confirm that a recharge is all it needs. If the system is otherwise sealed and healthy, we recharge it and send you on your way. If leaks are present, we’ll document and show them before you spend money on refrigerant.

Our Diagnostic Philosophy

A/C work is about more than adding refrigerant. We measure pressures, run system performance tests, and check every component that affects cooling. Our Ready-Set-Go™ Method ensures the root cause is confirmed before any repair begins. You get a straight report with findings, repair options, and pricing—fast and clear.

Common A/C Problems We Repair

  • Weak airflow from vents

  • Unusual noises when A/C is on

  • Bad odors from vents

  • A/C cuts out intermittently

  • Visible leaks or low refrigerant levels

Tools and Methods We Use

  • Our process uses industry-grade equipment and precise testing to confirm faults.

  • Robinair refrigerant recovery machine for safe handling

  • Mastercool A/C manifold gauges for pressure checks

Why You Shouldn’t Wait

Driving in San Antonio heat without A/C isn’t just uncomfortable—it’s unsafe in traffic or long trips. Running low on refrigerant can overheat the compressor and lead to costly damage. Prompt diagnosis keeps you cool and prevents larger repairs.
