Commercial AHU (Air Handling Unit) Repair in Calabasas

Your air handling unit is the heart of your commercial HVAC system. When it struggles, energy costs rise and comfort drops. At #1 AC Guys, we specialize in diagnosing and repairing AHUs in offices, retail, hospitality, healthcare, schools, industrial spaces, and multifamily common areas throughout Calabasas and Los Angeles County. As a 4th‑generation family of engineers with 80+ years of engineering experience, we bring advanced problem‑solving to every service call, from legacy constant‑volume units to modern VAV and DOAS configurations.

What we repair and optimize

• Motors, VFDs, starters, contactors, and control boards
• Bearings, sheaves, pulleys, shafts, and alignment
• Belts, filters, access doors, and panel seals
• Cooling and heating coils, valves, actuators, and drain pans
• Economizers, outside air dampers, and mixed‑air sections
• Fan arrays, blower wheels, housings, and vibration isolation
• Sensors (temperature, humidity, pressure) and airflow measurement stations
• BAS/BMS integration, safeties, and sequence optimization

We pair hands‑on mechanical skill with precise instrumentation—static pressure mapping, airflow balance checks, thermography, electrical testing, and vibration analysis—to locate root causes, not just symptoms.

Symptoms your AHU needs repair

• Hot/cold spots, poor airflow, or rising static pressure
• Unusual noise, vibration, or belt dust in the cabinet
• Coil icing, high humidity, or musty odors
• Frequent trips, VFD faults, or erratic BAS readings
• Rising energy bills despite normal occupancy

Ignoring these signs risks bigger failures and unplanned downtime. Our mission is healthier indoor air and reliable comfort with minimal disruption to your operations.

Our commercial AHU repair process

• Discovery: Site survey, review of service history, and business priorities
• Diagnostics: Electrical, mechanical, and controls testing with documented readings
• Plan: Clear options—repair, refurbish, or targeted upgrades for efficiency
• Execution: Safe, code‑compliant work, containment when needed, and start‑up commissioning
• Verification: Airflow, temperature, and controls validation with before/after data

Where appropriate, we recommend energy‑saving corrections—proper economizer operation, tighter control sequences, leakage reduction, and fan optimization—to reduce kWh without sacrificing comfort.
