Auto AC Repair & Service
AC not blowing cold in Thousand Oaks? Don't suffer through another hot Southern California summer with a broken air conditioner. At Gallardo's Automotive Service, our certified technicians diagnose and repair all automotive AC systems – from simple recharges to complete system overhauls.
Signs Your Car's AC Needs Service
Watch for these warning signs that indicate your AC system needs attention:
- AC blows warm or hot air – the most obvious sign of trouble
- Weak airflow from vents even at maximum settings
- AC works intermittently – cools sometimes but not others
- Strange noises when AC is running (grinding, squealing, clicking)
- Musty or moldy smell from vents – indicates bacterial growth
- Water pooling on passenger floor – clogged drain line
- AC clutch not engaging – compressor doesn't kick on
- Visible refrigerant leak – oily residue around AC components
Our AC Diagnostic Process
We don't guess – we diagnose. Our comprehensive AC inspection includes:
What We Check
- System pressure test – verify high and low side pressures
- Refrigerant level check – measure exact charge amount
- Vent temperature test – measure actual cooling output
- Compressor operation – check clutch engagement and function
- Leak detection – electronic sniffer and UV dye testing
- Electrical system test – relays, switches, and wiring
- Drive belt inspection – check for wear and proper tension
- Cabin air filter – dirty filters reduce airflow
- Condenser inspection – check for debris and damage
- Evaporator drain – ensure proper drainage
Common AC Problems We Fix
| Problem | Common Causes | Symptoms |
|---|---|---|
| Low Refrigerant | Leak in system, aging seals | Weak cooling, warm air |
| Compressor Failure | Wear, lack of lubrication, electrical issue | No cooling, loud noise, clutch won't engage |
| Condenser Problems | Damage, debris blockage, leaks | Poor cooling, especially at idle |
| Evaporator Leak | Corrosion, age | Gradual cooling loss, musty smell |
| Electrical Issues | Failed relay, blown fuse, wiring damage | Intermittent or no cooling |
| Clogged Expansion Valve | Debris, moisture contamination | Inconsistent cooling, icing |
AC Services We Provide
AC Recharge (Performance Service)
If your system is low on refrigerant but not leaking, we can recharge it to restore full cooling. This service includes evacuating old refrigerant, adding fresh refrigerant to factory specs, and adding UV dye for future leak detection.
AC Leak Repair
We use electronic leak detectors and UV dye to find even the smallest leaks. Once located, we repair or replace the leaking component and recharge the system.
Compressor Replacement
A failed compressor is a major repair. We replace compressors with quality units, flush the system to remove debris, replace the receiver/dryer, and recharge with fresh refrigerant and oil.
Evaporator & Condenser Service
These heat exchangers are critical for cooling. We repair or replace damaged units and restore full system function.
AC System Flush
After major component failure, we flush the entire system to remove contaminants before installing new parts.
Cabin Air Filter Replacement
A clogged cabin filter reduces airflow and allows pollutants into your vehicle. We recommend replacement every 15,000-25,000 miles.
What to Expect: Timeframes
| Service | Typical Time |
|---|---|
| AC Performance Check | 30-45 minutes |
| AC Recharge | 45-60 minutes |
| Leak Detection & Repair | 1-3 hours (depending on location) |
| Compressor Replacement | 2-4 hours |
| Evaporator Replacement | 4-8 hours (dash removal required) |

Frequently Asked Questions
How often should I service my car's AC?
We recommend an AC performance check annually, ideally before summer. Your AC system doesn't require regular fluid changes like other systems, but seals can dry out and refrigerant can slowly leak over time.
Can I just add refrigerant myself?
Store-bought recharge kits can temporarily mask problems while causing long-term damage. They often overcharge the system, contain sealers that clog components, and don't address the underlying leak. Professional service is always the better choice.
Why does my AC smell musty?
Moisture on the evaporator creates an environment for mold and bacteria growth. We can treat this with an evaporator cleaning service and recommend regular cabin air filter replacement to prevent recurrence.
My AC works at highway speed but not at idle. Why?
This often indicates a condenser airflow problem (debris blockage, failed fan) or low refrigerant charge. The system needs more airflow across the condenser when the vehicle isn't moving.
Does running the AC hurt fuel economy?
The AC compressor does add some load to the engine, typically reducing fuel economy by 1-4 MPG. However, at highway speeds, running AC is often more efficient than opening windows, which creates aerodynamic drag.
