Common Questions

AC Repair FAQs

How much does AC repair cost in Southern California?

Most AC repairs range from $150 to $800 depending on the component. Common repairs like capacitor or contactor replacement run $150–$300. Refrigerant recharges range from $200–$500 depending on the refrigerant type and amount needed. Compressor replacement can reach $1,200–$2,500. We provide a written upfront quote before starting any work — no surprises.

How quickly can you respond to an AC repair call?

We offer same-day service for most calls throughout Southern California. During peak summer season, we prioritize emergency no-cooling calls and can typically have a NATE-certified technician at your home within 2–4 hours. Call (951) 277-6895 for same-day availability.

Do you repair all AC brands?

Yes — our technicians are trained on all major residential AC brands including Carrier, Trane, Lennox, Daikin, Rheem, Goodman, York, Bryant, American Standard, and more. We service both central ducted systems and ductless mini-splits.

Should I repair or replace my AC?

If your system is under 10 years old and the repair cost is less than 50% of replacement cost, repair is usually the right choice. For systems over 10–12 years old with a major component failure, replacement often makes more financial sense — especially with available utility rebates and 0% financing. We'll give you an honest assessment.

What are the most common AC problems in Southern California?

The most common AC issues we see in Southern California are failed capacitors (the component that starts the compressor and fan motors), low refrigerant due to a leak, dirty evaporator or condenser coils, failed contactors, and frozen evaporator coils caused by restricted airflow. Most of these are straightforward repairs when caught early.

How do I know if my AC needs refrigerant?

Signs your AC is low on refrigerant include: the system blows warm or barely cool air, ice forms on the refrigerant lines or indoor coil, your energy bills increase without explanation, or you hear a hissing or bubbling sound near the unit. Low refrigerant almost always means there is a leak — adding refrigerant without fixing the leak is only a temporary fix. Our technicians locate and repair the leak before recharging.

Why is my AC running but not cooling the house?

Several issues can cause an AC to run without cooling effectively: low refrigerant, a dirty air filter restricting airflow, a frozen evaporator coil, a failed capacitor preventing the compressor from starting, or a refrigerant metering device failure. A proper diagnosis by a NATE-certified technician is the fastest way to identify and fix the root cause.

Do you offer a warranty on AC repairs?

Yes. All parts and labor are covered by a written warranty. The specific warranty period depends on the repair type and parts used. We'll provide warranty documentation with every completed repair.
