AC Repair and Recharge Pflugerville

A failing AC system is one of the most uncomfortable problems a vehicle can develop—especially in the Texas heat. Austin Auto Repair Pros provides mobile AC repair, AC recharge, and full air conditioning diagnostics throughout Austin, Round Rock, Pflugerville, Hutto, and Georgetown. Our mobile mechanics come directly to your home or workplace with the tools needed to diagnose cooling issues and restore proper function without requiring a trip to a shop.

AC systems rely on proper refrigerant levels, leak-free lines, strong electrical components, and consistent compressor performance. When any part of this system fails, the air may feel warm, weak, inconsistent, or stop blowing cold altogether. Our mobile technicians use advanced diagnostic procedures to determine exactly why the AC is not cooling and perform repairs on-site when possible.

Common AC Issues We Diagnose and Repair

Many AC problems follow predictable patterns. Our mechanics regularly handle:

• Warm air blowing from the vents

• AC not blowing at all

• Weak airflow or intermittent cooling

• AC working only while driving

• Strange smells from vents

• Clicking noises when AC engages

• Refrigerant leaks

• Compressor failure

• Blower motor or resistor issues

• Expansion valve or orifice tube problems

• Faulty pressure sensors

• Electrical issues affecting AC performance

By identifying the root cause, our mechanics prevent unnecessary part replacements and help restore reliable cooling quickly.

AC Recharge Services

If your AC system is low on refrigerant, it cannot produce cold air. A recharge involves:

• Checking refrigerant pressure

• Inspecting for leaks

• Adding the correct refrigerant type

• Measuring vent temperature

• Ensuring pressure readings are within manufacturer specifications

Refrigerant does not get “used up”, so low levels typically indicate a leak. Detecting and addressing leaks prevents the system from warming up again shortly after service.

AC Leak Detection and Repair

Refrigerant leaks are the most common reason AC systems fail. Our mechanics use UV dye, pressure testing, and visual inspection to identify leaks in components such as:

• AC hoses and lines

• Compressor seals

• Condenser

• Evaporator

• Schrader valves

• O-rings and fittings

Some leaks can be repaired on-site, while others may require shop-level access depending on part location.

Electrical and Sensor Diagnostics

Many AC failures originate from electrical components, not refrigerant. Our diagnostics inspect:

• Blower motor power

• Blower motor resistor

• AC relays and fuses

• Pressure switches

• AC clutch and compressor activation

• Temperature control modules

• HVAC control panel function

Electrical faults often cause AC to turn on and off unpredictably or fail entirely.

Compressor and Condenser Issues

If the compressor is failing, the AC may produce weak or intermittent cold air. Condenser problems may affect cooling efficiency, especially at idle. Our mechanics identify whether repair is possible or if component replacement is required.

Benefits of Mobile AC Repair

Mobile AC service saves time and eliminates the need for a long shop visit or towing. Instead of waiting in a lobby, you receive diagnostics and repair directly at your location. Because AC failures often make driving uncomfortable or unsafe in summer heat, mobile repair provides immediate relief and keeps the vehicle functional without delays.

Frequently Asked Questions

Can all AC repairs be done on-site?

Most AC diagnostics, recharges, and electrical repairs can be done on-location. Some internal components—such as evaporators—may require a shop.

How long does an AC recharge take?

Most recharges take 20 to 40 minutes depending on system condition.

Why is my AC blowing warm air?

Common causes include low refrigerant, leaks, sensor issues, electrical faults, compressor problems, or airflow restrictions.

Can you fix AC issues at an apartment or workplace?

Yes. AC diagnostics and recharge can be performed in driveways, apartment lots, and parking garages.

Does low refrigerant always mean a leak?

Almost always. Refrigerant does not evaporate on its own—low levels usually indicate a leak that should be checked.

Do you use the correct refrigerant for my vehicle?

Yes. Mechanics use the proper refrigerant type and specification for your exact make and model.
