Commercial HVAC Service for Businesses
Commercial HVAC is a different animal — packaged rooftop units, larger tonnage, staged compressors, economizer dampers, occupancy schedules, and uptime requirements that residential systems do not have. We service commercial buildings across Nevada County during regular business hours, including restaurants, retail, offices, and light-industrial spaces.

Frequently asked
Do you have 24/7 commercial service?
No. We operate Monday through Friday, 8 AM to 5 PM. We are clear about that up front because we believe a real local technician during business hours beats an after-hours dispatcher routing your call somewhere else.
Do you offer maintenance contracts?
Yes. Quarterly and semi-annual maintenance contracts for commercial buildings — sized to your equipment count and tenant requirements. These dramatically reduce emergency calls.
What size buildings do you service?
Small to mid-size commercial — restaurants, retail bays, offices, light industrial. For very large industrial or specialty applications (clean rooms, complex chillers) we will refer you to a contractor better positioned for that scope.
