Commercial AHU (Air Handling Unit) Repair in Santa Monica — AC PRO Systems

Expert Commercial Repair for AC PRO Air Handling Units

When your AC PRO AHU falters, every minute matters. #1 AC Guys brings deep engineering discipline to commercial air handler repair in Santa Monica—isolating faults fast, restoring safe, efficient airflow, and documenting performance so facilities teams can trust the results.

We are a 4th‑generation family business with 80+ years in engineering. Our mission is healthy indoor air for a healthy life, achieved through meticulous diagnostics, code‑compliant repairs, and optimization that reduces energy waste while improving comfort and indoor air quality.

What we repair on AC PRO AHUs

• Fans and drives: ECMs, VFDs, motors, bearings, shafts, pulleys, and belts
• Coils and hydronics: DX and chilled water coils, hot water reheat, valves, strainers, traps, and drain pans
• Airflow and mixing: dampers, actuators, linkages, economizers, outside air and return air assemblies
• Controls and sensors: control boards, relays, pressure/temperature/humidity/CO₂ sensors, safeties
• Filtration and IAQ: MERV 13+, HEPA modules, UV‑C, bipolar ionization (when appropriate), gasketing and sealing
• Housing and sealing: access doors, insulation, liners, air leaks, vibration isolation

Common symptoms we solve

• Low airflow, hot/cold spots, or zones not meeting setpoint
• Short cycling, nuisance trips, or VFD/motor faults
• High static pressure, noisy operation, or vibration
• Coil icing, condensate leaks, or musty odors
• Economizer failures, outside air control issues, or poor ventilation
• Controls out of calibration or BAS communication problems (BACnet/Modbus)

Our repair process

• Assessment: interview ops team, review alarms/logs, verify sequence of operations
• Diagnostics: electrical, mechanical, and airflow testing; trending static pressure, CFM, and temperature split
• Root cause: isolate component failure vs. control logic or design/maintenance issue
• Repair: replace/repair components, align and tension drives, calibrate sensors/actuators, seal air leaks
• Optimization: set VFD parameters, economizer limits, ventilation rates; verify against ASHRAE 62.1 and Title 24 where applicable
• Verification: test and balance checks, document readings, and deliver a clear service report

Faster uptime with strong parts access

We service AC PRO air handling units daily and source parts quickly through established local distribution channels, helping minimize downtime for Santa Monica facilities. We install high‑quality, manufacturer‑approved or spec‑compliant components and always review compatibility before replacement.

Preventive maintenance and IAQ upgrades

• Seasonal PMs: bearings, belts, lubrication, coil cleaning, drain treatment, filter strategy, and control checks
• Energy upgrades: VFD tuning, advanced economizer controls, demand‑controlled ventilation
• IAQ improvements: MERV 13+ filters, HEPA modules, UV‑C for coils, sealing and gasketing to reduce bypass
• Commissioning support: functional testing, air balancing coordination, and reporting

Standards and compliance

Our repairs align with California Title 24 energy requirements and ASHRAE 62.1 ventilation guidance. We work with your facility team to meet company standards and local codes while maintaining comfort and efficiency.

Training and expertise
