Repair Questions, Answered
Do you offer same-day or emergency HVAC repair?
Yes. A broken system in Georgia's heat or cold can't wait, so we offer fast, responsive service with same-day appointments available in most cases. Call (678) 853-7440 and we'll get a technician to you as quickly as possible.
How much does HVAC repair cost?
It depends on the part and the problem. A typical diagnostic runs about $79–$149, common fixes like a capacitor or contactor run roughly $150–$450, and larger repairs cost more. We always diagnose first and give you an upfront, honest price before any work begins — no surprises.
Why is my AC running but not cooling or blowing warm air?
Common causes include a dirty filter or coil, low or leaking refrigerant, a failing capacitor or compressor, a frozen evaporator coil, or a thermostat issue. Some have quick fixes; others need a pro. We'll diagnose the real cause and tell you exactly what it takes to get cold air flowing again.
Should I repair or replace my HVAC system?
If your system is under about 10 years old and the repair is minor, repair usually makes sense. If it's older or needs a major repair, replacement may be the smarter long-term value. We give you honest numbers either way so you can decide with confidence.
What are common signs my HVAC needs repair?
Warm air or weak cooling, poor airflow, water leaks or a frozen unit, strange noises or smells, short cycling, thermostat problems, high humidity, or rising energy bills are all signs your system needs attention. The sooner we look, the smaller the repair usually is.
Do you repair all HVAC brands?
Yes. Our NATE-certified technicians repair all major brands — Lennox, Trane, Carrier, Daikin, American Standard, Bryant, Goodman, and Amana — no matter who originally installed your system.
How often should my AC system be serviced?
At least once a year — ideally spring for cooling and fall for heating. Regular maintenance catches small issues before they become costly breakdowns and keeps your system efficient and under warranty. Ask about our Club Zen membership.
Is it worth repairing an older AC unit?
It depends on age, repair cost, and overall condition. A good rule of thumb: if the repair costs more than about half the price of a new unit on a system over 10–15 years old, replacement is often the better investment. We'll give you an honest recommendation, never a sales pitch.
