HVAC System Questions

Whole-system HVAC FAQ

What does a maintenance plan include?

Two scheduled tune-ups per year (spring AC, fall heating), priority scheduling when you call, no after-hours service fees, and discounts on parts & labor for any repairs. We catch small problems before they become expensive ones.

Do you service commercial HVAC systems?

Yes. We service rooftop units, chilled water systems, VRF, and packaged units for retail, office, restaurant, and warehouse properties across Gwinnett County. Service contracts available with priority response.

How often should my whole system be serviced?

Twice a year — once in spring for the cooling side, once in fall for the heating side. This is the cadence manufacturers require for warranty coverage and what we'd do on our own family's systems.

My whole system seems off — where do I start?

Start with a diagnostic visit. A NATE-certified tech checks every component — air handler, condenser, ductwork, thermostat, refrigerant levels — and tells you what's working, what's marginal, and what needs immediate attention. Honest, no upsells.
