FAQ

Service area questions

Quick answers about coverage, response times, and licensing across our South Florida HVAC service area.

Which South Florida counties does ONC Air service?
ONC Air provides residential and commercial HVAC services across Miami-Dade, Broward, and Palm Beach counties — covering coastal cities, inland suburbs, and gated estate communities throughout the region.

How fast can a technician reach my city for emergency HVAC service?
For most cities in our service area we offer same-day arrival on emergency calls and 24/7 dispatch. Coastal and central neighborhoods typically see a technician within 60–90 minutes of booking.

My city isn't listed — do you still service it?
Likely yes. The cities listed are the ones with dedicated landing pages, but our crews routinely service neighboring zip codes throughout South Florida. Call 866-260-5663 and we'll confirm coverage for your address.

Are your technicians licensed in every county you serve?
Yes. ONC Air is fully licensed and insured for HVAC work in Miami-Dade, Broward, and Palm Beach counties, including permits required for new installs, equipment replacements, and commercial mechanical work.

Do you charge extra for service in certain cities?
No. Diagnostic, service-call, and emergency-response fees are the same across our entire South Florida service area — you'll never pay more because of your zip code.

Do you handle both residential and commercial HVAC in every city?
Yes. Every city we list supports residential service (repair, install, maintenance, indoor air quality) and commercial work (VRF, cooling towers, refrigeration, building automation).

Don't see your city? We probably still serve it.
