AC Repair in Southern California
If your AC is blowing warm air, leaking water, making noise, or not turning on, Sun Tech can help. We diagnose the problem, explain the options in plain English or Korean, and help you decide what makes sense before work begins.
Fastest option: call or text your city, HVAC problem, and photos of the indoor and outdoor units if possible. 한국어 상담 가능합니다.
What This Service Covers
AC repair is usually the right first step when the system is under 12 to 15 years old, the repair is small, or the unit has been reliable until now. Our technician checks airflow, refrigerant pressure, electrical parts, thermostat settings, drain lines, and the outdoor condenser so you are not guessing.
Cost and Estimate Notes
Common AC repairs often start around $150 to $600 for parts like capacitors, contactors, drain clearing, and basic electrical fixes. Larger repairs such as fan motors, refrigerant leaks, coils, or compressors can cost more. We give a clear price before repair.

Frequently Asked Questions
How fast can Sun Tech handle AC repair?
Same-day AC repair is often available when the schedule allows. Texting your city, the AC symptom, and a photo of the unit helps us respond faster.
Should I repair or replace my AC?
Repair is often best for newer systems with a clear, affordable problem. Replacement may make more sense when the system is 15 years old, uses older refrigerant, or needs a major repair.
Can you explain the AC repair in Korean?
Yes. Sun Tech provides Korean and English support so families can understand the problem, the price, and the repair choice before approving work.
