Frequently Asked Questions
My AC stopped cooling during a Lithonia heat wave. What's a common cause, and how quickly can you help?
A frequent culprit during our hot summers is a failed AC capacitor, which prevents your outdoor unit from starting. We prioritize these emergency calls for Lithonia residents to restore cooling quickly. Our technicians are stocked with common parts to provide same-day service whenever possible, getting your system back online before the heat becomes unbearable.
How often should I schedule maintenance for my HVAC system in our Georgia climate?
We recommend professional maintenance twice a year—once in spring for your AC and once in fall for your heating system. Our thorough maintenance service checks refrigerant levels, cleans coils, inspects electrical components, and ensures everything is running efficiently. This proactive care helps prevent mid-summer breakdowns, extends your system's life, and keeps energy costs in check.
