Auto A/C Repair FAQ
Why is my A/C cold while driving but warm at idle?
Possible causes include airflow, fan, charge or compressor-control problems. Testing is needed because several systems can create the same symptom.
Can you just add refrigerant?
Low refrigerant usually means the system has lost charge. A proper evaluation helps avoid repeatedly adding refrigerant without addressing the cause.
Do you handle all types of A/C repairs?
We diagnose and repair many A/C concerns. The examples shown are not a complete list, and some work must be performed at the shop with appropriate equipment.
