Commercial AHU (Air Handling Unit) Repair in Oxnard

Downtime is costly. Our Oxnard commercial AHU repair service is designed to get your air handling unit back online quickly and safely, whether you run a coastal warehouse near the Port of Hueneme, a biotech lab, a retail center, or a hospitality venue. We work on AC PRO–supported systems and components, and we stock common parts to speed up first‑visit repairs.

What we repair on commercial AHUs

• Fan arrays, supply/return fans, motors, and VFDs
• Bearings, shafts, belts, sheaves, and alignment
• Cooling/heating coils, drain pans, traps, and condensate lines
• Outdoor air/economizer assemblies, dampers, and actuators
• Filters, HEPA and MERV upgrades, UV-C, and IAQ accessories
• Control boards, sensors, safeties, contactors, and transformers
• BMS integrations, economizer logic, alarms, and sequences
• Cabinets, access panels, insulation, and corrosion mitigation for coastal air

From rooftop AHUs to built‑up mechanical room units, we correct airflow imbalances, repair leaks, replace worn components, and recalibrate controls to restore capacity and ventilation rates. We can also address noise, vibration, and energy spikes often tied to failing bearings or misapplied control sequences.

Fast diagnostics built for business

Our engineers start with targeted diagnostics: static pressure profiling, temperature splits, vibration and thermal imaging, motor/VFD trending, and controls review. You’ll receive a clear, prioritized report—what failed, why it failed, and what it will take to prevent repeat issues.

• Root‑cause analysis focused on reliability and energy
• Actionable repair options with transparent pricing
• Temporary measures to keep air moving when parts are en route

Coastal environments demand corrosion awareness. We address salt‑air impact with protective coatings, stainless hardware options, and maintenance strategies that extend the life of coils, fasteners, and housings.

Our repair process

1) Assess: We verify the complaint, inspect the AHU, and benchmark airflow, pressures, and temperatures. 2) Stabilize: We secure safeties, address immediate risks, and implement temporary solutions if needed. 3) Repair: We replace failed parts, correct control logic, seal leaks, and set proper belt tension and alignment. 4) Commission: We validate performance—airflow, economizer operation, and ventilation rates—then document results for your records.

Indoor air quality and compliance

Healthy air is our core mission. We help you meet ventilation and filtration goals aligned with California Title 24 guidance and industry best practices. Options include MERV upgrades, UV‑C, outside air optimization, and demand‑controlled ventilation where appropriate.

Preventive care and upgrades

After the repair, we can structure a maintenance program to reduce unplanned downtime and energy waste. We also offer optimization upgrades—economizer tune‑ups, high‑efficiency motors, VFDs, and control sequence refinements—to protect your budget and indoor air quality.

• Seasonal inspections and coil cleaning
• Belt, bearing, and alignment checks
• Filter strategies matched to your process and IAQ targets
• BMS analytics to catch faults early
