A/C Diagnosis and Repair in San Antonio
Weak airflow, warm air, or A/C that cuts out in San Antonio heat? Get it checked before it gets expensive.
If your A/C is blowing warm, cooling poorly, making noise, smelling strange, or cutting out on hot days, Caleb’s Car Care can help.
Caleb’s Car Care provides mobile A/C diagnosis and repair in San Antonio. We come to your home, apartment, office, or wherever your vehicle is parked to inspect the system, find the problem, and explain the repair options clearly.
A/C problems are not always solved by adding refrigerant. Low refrigerant, leaks, electrical faults, compressor problems, blower motor issues, condenser restrictions, control problems, and sensor failures can all create similar symptoms.

FAQs
How long does an A/C diagnosis take?
Most A/C diagnostic visits take about 45–90 minutes, depending on the symptoms and the vehicle.
We test the system, check refrigerant pressures, inspect related components, and look for leaks or electrical problems before recommending repairs.
Do you recharge refrigerant on-site?
Yes, when the system is sealed and a recharge is the correct repair.
We do not blindly add refrigerant just because the air is warm. We confirm what the system needs first so you are not paying for a temporary fix that leaks right back out.
Can you fix electrical A/C problems too?
Yes. Many A/C problems are electrical, not just refrigerant-related.
We can test wiring, relays, fuses, sensors, switches, control signals, blower motor operation, compressor command, and related circuits to help identify the real issue.
Is the diagnostic fee applied to repairs?
No. A/C diagnosis is billed separately at $150–$190 and is not credited toward repairs.
That keeps the diagnostic process clear and prevents guesswork from being folded into repair pricing.
What if my A/C just needs a recharge?
If the system is sealed, healthy, and truly only needs a recharge, we’ll explain that and handle it appropriately.
If leaks are present, we’ll document the concern and explain the repair options before you spend money on refrigerant that may not stay in the system.
Can you repair A/C leaks on-site?
In many cases, yes. We can identify and repair many A/C leaks when the repair is accessible and appropriate for mobile service.
Leaks may come from hoses, fittings, service ports, condensers, compressors, evaporators, or other components. We inspect first so we know what we’re dealing with.
Do A/C repairs include a warranty?
Yes. Eligible A/C repairs include a 1-year parts and labor warranty.
We’ll explain the repair, parts, and warranty details before moving forward.
What Makes Us Different 🛠️
❄️ Diagnosis Before Recharge — We do not blindly add refrigerant and hope. We test first so you know what the system actually needs.
🔍 Leak Detection — We use proper leak detection methods to help find the source instead of guessing.
⚙️ Mechanical and Electrical Testing — A/C problems can involve refrigerant, compressors, fans, sensors, wiring, relays, controls, or airflow. We check the system, not just one part.
🚗 Mobile A/C Service — We come to your location when the job is a good fit for on-site diagnosis and repair.
📋 Clear Repair Options — You get a straightforward explanation of what we found, what it means, and what should happen next.
🛡️ Warranty-Backed Repairs — Eligible A/C repairs are backed by a 1-year parts and labor warranty.
Our Diagnostic Philosophy 🔍
A/C work is about more than adding refrigerant.
Warm air can be caused by low refrigerant, a leak, a compressor issue, a cooling fan problem, a pressure sensor, a blower motor concern, a control fault, a restricted condenser, or an electrical issue.
That is why Caleb’s Car Care starts with diagnosis.
Our goal is simple:
Find the real reason your A/C is not cooling
Explain what is happening in plain English
Avoid blind recharges and wasted money
Repair the problem on-site when mobile service is a good fit
Tell you clearly when the repair needs a shop or specialty path

Why You Shouldn’t Wait ⚠️
Driving in San Antonio heat without A/C is miserable, and sometimes unsafe.
Low refrigerant can overwork the compressor. Small leaks can turn into bigger repairs. Electrical faults can damage components. A weak cooling fan or airflow issue can make the system work harder than it should.
The sooner you diagnose the problem, the better chance you have of avoiding wasted refrigerant, unnecessary parts, or a more expensive A/C repair later.
