Yes, a failed AC capacitor is one of the most frequent causes of sudden cooling loss, especially during our hot Georgia summers. This component helps start your outdoor unit's motor.

If your system is over 10-15 years old, requires frequent repairs, or struggles to maintain comfort, a replacement is often more cost-effective.

We provide honest assessments to help you decide between repair and replacement based on your home's needs and budget.
