When your car’s air conditioner stops cooling, the first question most drivers ask is, “How long will it take to fix?” If you’re using a mobile AC repair service, you’re already saving time by skipping the shop—but understanding the process can help you plan your day even better.

Here’s what to expect during a mobile AC repair, how long each step usually takes, and what factors can affect the total repair time.

1. Initial Inspection and Diagnosis (15–30 Minutes)

Every mobile AC service starts with a diagnostic check. The technician uses specialized gauges and sensors to measure refrigerant pressure, check for leaks, and test electrical components.

During this phase, they’ll determine whether the problem is simple (like low refrigerant) or more complex (like a compressor failure).

Tip: Most mobile techs can perform these diagnostics right in your driveway or parking lot—no towing required.

2. Leak Testing and System Evaluation (15–20 Minutes)

If the refrigerant level is low, the technician will test for leaks. This can be done using UV dye, an electronic sniffer, or a pressure test.

Small leaks in hoses or valves can often be repaired immediately, while larger leaks or component failures might require part replacement.

By catching leaks early, you save money and prevent bigger issues later.

3. AC Recharge or Refrigerant Replacement (20–40 Minutes)

Once leaks are fixed and the system passes inspection, it’s time to recharge the refrigerant.

A technician will:

• Remove old or contaminated refrigerant
  
  

• Vacuum out air and moisture
  
  

• Add the correct type and amount of refrigerant

This step is precise and critical for your AC’s performance. If done right, you’ll feel the difference almost instantly.

4. Electrical or Component Repairs (30–90 Minutes, Depending on Issue)

If diagnostics reveal a bad relay, switch, or clutch, the technician can usually replace these parts on-site.
However, compressor or condenser replacements can take longer—up to 1.5 hours—depending on the make and model of your vehicle.

Pro Tip: Mobile repair vans typically stock common parts, so you can often get repairs done the same day.

5. System Testing and Performance Verification (10–15 Minutes)

After the repair, your technician will re-test the system to ensure proper cooling and airflow. They’ll check:

• Vent temperature consistency
  
  

• Compressor engagement
  
  

• Electrical response times
  
  

• Pressure readings under load

This ensures your AC performs as well as it did when it left the factory.

Total Time Estimate: 45–120 Minutes

Most mobile car AC repairs are completed in under two hours, making it far faster and more convenient than dropping your car off at a shop.
For simple recharges or small leaks, it could take less than an hour. For complex repairs, plan for up to two hours max.
