Commercial AHU (Air Handling Unit) Repair in Burbank, CA

Your Air Handling Unit is the heart of your building’s HVAC. In Burbank’s busy commercial environments—offices, studios, hospitality, healthcare, retail, and light industrial—unplanned AHU downtime can disrupt operations and comfort. #1 AC Guys combines 80+ years of engineering know‑how with fast field execution to restore reliable, efficient, and healthy airflow with minimal disruption.

Our Commercial AHU Repair Expertise

• Supply/return/exhaust fan assemblies: motors, bearings, shafts, belts, sheaves, and alignment
• Variable Frequency Drives (VFDs): programming, faults, harmonics, and replacements
• Coils: chilled, hot water, DX—leaks, blockages, cleaning, and replacements
• Drain pans and condensate: clogs, pump failures, microbial growth mitigation
• Dampers and actuators: economizers, outdoor air and return air mixing, minimum position
• Sensors and controls: temperature, humidity, pressure, airflow, safeties, and control boards
• Filtration and IAQ: filter rack sealing, MERV upgrades, UV and air quality strategies
• Make‑up air units and rooftop AHUs: heat sections, gas trains, ignition, and safeties

Common Signs Your AHU Needs Service

• Hot/cold spots, poor ventilation, or pressure imbalance between zones
• Alarms from BAS/BMS, VFD trips, or short cycling
• Unusual noise (grinding, squeal) or vibration from the fan section
• Rising energy bills, low airflow, or failure to meet setpoints
• Water leaks, musty odors, or frequent filter loading

Diagnostics-Driven Process

Our approach is engineered for accuracy and speed. We start with a focused interview on the building’s symptoms and operating schedule, then perform a systematic check of airflow, static pressure, electrical, control logic, and mechanical components. We verify economizer operation, damper positions, and sensor calibration and confirm sequence of operations against your BAS. You receive a clear, itemized estimate with good/better/best options before work proceeds.

• Root-cause testing: electrical, mechanical, and control diagnostics
• On-the-spot stabilizing repairs to minimize downtime
• Performance restoration: airflow balance checks and setpoint validation
• Documented results for your maintenance records and compliance

Factory-Trained for Complex Systems

Our engineers are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background helps us handle sophisticated control sequences, multi-zone VAV systems, and retrofits that integrate cleanly with your BAS. Whether you operate a studio in Burbank or a medical office that demands strict IAQ, we solve complex issues efficiently and safely.

Compliance, IAQ, and Safety

We align repairs with California energy standards and local requirements, and we engineer solutions that support healthy indoor air—proper outdoor air intake, accurate economizer logic, filtration upgrades, clean drain management, and coil hygiene. Our mission is healthy indoor air for healthy lives, delivered with commercial reliability.

What to Expect During a Service Visit

• Arrival window updates and safe worksite setup
• Mechanical and electrical inspection of the fan section and drives
• Controls and sensor verification, including economizer and OA/RA ratios
• Filter, coil, and condensate evaluation, with on-the-spot corrections when feasible
• Functional run test and performance report with recommendations

Industries We Serve in and around Burbank

• Office, retail, and mixed-use buildings
• Studios, soundstages, and post‑production facilities
• Healthcare clinics and wellness spaces

Service Area and Response Times

We prioritize rapid dispatch in Burbank and across Los Angeles County, and we also serve nearby Orange County, Ventura County, and Western Riverside County. Same‑day service is available for most commercial AHU issues, with 24/7 emergency coverage to protect your operations.

Repair, Retrofit, or Replace?

Not every AHU needs replacement. We provide options based on lifecycle cost and risk: targeted repairs to extend life, retrofits like VFDs and advanced economizer controls for better efficiency, or full replacements when structure, capacity, or reliability make it the smart long‑term move. You get the data to choose with confidence.

Proactive Maintenance for Fewer Breakdowns

Preventive care stabilizes airflow, reduces energy waste, and protects indoor air quality.

• Quarterly inspections tailored to your usage and occupancy
• Belt, bearing, and alignment checks with vibration trend tracking
• Coil cleaning and drain pan sanitation to control biofilm and odors
• Filter strategy: correct MERV, sealed racks, pressure drop monitoring
• Controls calibration and economizer verification at each season change

Ask about right‑sized maintenance plans that fit your budget and compliance needs—ideal for multi‑site portfolios and high‑duty facilities.
