Industrial & Commercial HVAC Contractor for North Orange County
Managing an industrial strip property, warehouse, or retail space in North Orange County requires reliable infrastructure. When rooftop units (RTUs) fail during a heatwave, tenant complaints skyrocket, and business operations come to a halt. At Legit Air, we serve as the trusted HVAC partner for property management firms, facility directors, and business owners across Anaheim, Fullerton, Brea, and Placentia. Whether your tenants operate under NNN leases or you manage master maintenance contracts, our licensed commercial technicians are ready to deploy.
Common Rooftop Unit (RTU) & Commercial AC Problems We Solve
Heavy-tonnage commercial systems undergo massive stress, especially in industrial zones prone to dust, debris, and continuous operating hours. Our diagnostic team regularly resolves:
Failed Economizers & Dampers: Restoring proper outside air intake to keep your building compliant with commercial ventilation codes while maintaining energy efficiency.
Three-Phase Power & Contactor Issues: Replacing burnt electrical components, fuses, and pitted contactors that prevent heavy commercial compressors from firing up.
Clogged Coils & Refrigerant Leaks: Industrial environments clog condenser coils fast. We handle deep chemical washes, leak detection, and R-410A/R-22 refrigerant recovery and recharging.
Broken Belts & Worn Sheaves: Eliminating excessive vibration and squealing by replacing worn blower belts and greasing vital motor bearings to restore proper airflow to tenant spaces.
Why Local Property Managers Choose Legit Air
We know that as a property manager, you need two things: speed and proof. We don’t just fix the unit; we provide detailed, photo-backed service reports so you can confidently relay information to property owners or invoice tenants. By focusing our commercial HVAC services heavily in the North Orange County corridor, we keep our travel times low, allowing us to respond to emergency outages faster than massive, out-of-county corporate fleets.

RTU & Package Units
We provide rapid diagnostic response for all major commercial rooftop units. Our technicians handle compressor replacements, refrigerant leak detection, and economizer troubleshooting to keep your building compliant.
Preventative Maintenance
Protect your equipment with our quarterly or bi-annual PMAs. We manage belt tensioning, chemical coil washing, and strict filter schedules, providing photo reports for asset managers.

When it’s time to upgrade, we execute seamless heavy-tonnage installations. We coordinate crane lifts, rigging, custom curb adapters, and ducting modifications for full Title 24 compliance.
Server Rooms & Splits
Ensure critical systems stay cool. We install and maintain specialized ductless mini-splits for IT server rooms, warehouse office expansions, and spaces requiring dedicated climate control.
Ventilation & Make-Up Air
Comprehensive service for commercial exhaust fans and make-up air units (MAU). We ensure your facility maintains optimal indoor air quality and meets all safety codes.
