Common questions

Answers before you call.

Do you offer 24/7 emergency service?
Yes. Our emergency line is staffed around the clock. When your AC dies on a 95° afternoon or your furnace quits at 2 a.m., call (678) 361-0990 — a real technician returns the call, not a routing menu.
How fast can you get to my home?
Same-day for most service calls across Georgia. Emergencies bump to the front of the schedule. We'll give you an honest arrival window when you call — no "sometime between 8 and 6" runaround.
Do you give free estimates?
Yes — for installations and replacements, our estimates are free and there's never an obligation. We walk you through the options, the sizing math, and the warranty terms before you decide. Diagnostic calls on repairs carry a small visit fee that gets credited toward any work you approve.
Are you licensed and insured in Georgia?
Yes, fully licensed and insured to work in the State of Georgia on both residential and commercial HVAC and refrigeration systems. License details available on request.
How often should I service my AC?
Once a year for residential — ideally each spring before cooling season. A 20-minute tune-up catches small issues before they become a 95° emergency, keeps efficiency high, and is required to maintain most manufacturer warranties. Ask about our maintenance plans.
My AC is freezing up — what's wrong?
Usually low refrigerant from a leak, a dirty filter restricting airflow, or a failing blower. Don't keep running it — ice buildup can damage the compressor (a $1,500+ part). Turn the system off, switch the fan to ON to let it thaw, and call us. We'll find the actual cause, not just top off refrigerant and walk away.
