Commercial AHU (Air Handling Unit) Repair in Anaheim for AC PRO Systems

What We Repair on AC PRO Air Handling Units

Our engineers handle routine and advanced AHU issues across Anaheim’s commercial facilities, restoring reliability and air quality while reducing energy waste.

• Fans and drives: belt/sheave systems, direct‑drive assemblies, bearings, alignment, imbalance, vibration.
• Motors and controls: ECMs, contactors, starters, soft‑starts, VFD tuning and replacement.
• Coils and condensate: chilled/hot‑water and DX coils, leaks, corrosion, cleaning, drain pans, traps, condensate pumps.
• Airflow and dampers: outside/return/exhaust, economizers, mixing boxes, actuators, linkages, pressurization issues.
• Filtration and IAQ: filter racks, MERV upgrades, media fitment, bypass reduction, UV‑C add‑ons, odor and particulate control.
• Sensors and safeties: temperature, humidity, pressure, CO2, freeze stats, high‑limit cutouts.
• Controls/BAS: setpoints, sequences of operation, scheduling, alarms, BACnet integration, point‑to‑point verification.
• Casing integrity: access doors, gaskets, insulation repairs, air leakage, panel resonance and noise.

Whether your AC PRO AHU suffers from chronic hot/cold spots, short cycling, excess humidity, dirty coils, or controls drift, we pinpoint root cause and correct it—so you get stable comfort, compliance, and lower operating costs.

Our Engineered Process

1. Discovery & goals. We align with your facilities team on symptoms, risk, and downtime constraints.
2. Diagnostics. Instrumented testing of airflow, temperatures, static pressure, electrical health, and controls logic.
3. Root‑cause report. Clear findings with photos, options, budgets, and timelines—no surprises.
4. Repair & optimization. Parts replacement and corrective work executed to manufacturer specifications and California codes.
5. Commissioning. Verify sequences, tune VFDs, set economizer logic, balance airflow, confirm alarms and safeties.
6. Documentation. Final readings, as‑left settings, and maintenance guidance to protect your investment.
7. Preventive path. Tailored PM programs for filters, coils, belts, bearings, sensors, and controls—backed by performance checks.

Why Facilities Choose #1 AC Guys

• 80+ years of engineering expertise. Our fourth‑generation family of engineers is built for complex, high‑stakes AHU work.
• Commercial focus. We understand uptime, occupant comfort, and energy spend across multi‑site portfolios.
• Factory-trained competencies. Our engineers have trained at manufacturer facilities of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China).
• IAQ‑first mission. Healthy air in your building for a healthy life—delivered through proper filtration, cleanliness, and control.
• Anaheim and beyond. Rapid response across Anaheim and Orange County with coverage throughout Greater Los Angeles.
• Transparent communication. Actionable reports, code‑aligned recommendations, and clear budgets.

We service and repair AC PRO air handling units and adhere to manufacturer guidance without cutting corners. The result is predictable performance, cleaner air, and fewer callbacks.

Indoor Air Quality and Energy Performance

We treat air quality and energy as two sides of the same engineering problem. Right‑sized filtration (MERV upgrades with proper face velocity), clean coils, sealed panels, tuned dampers, and verified sensor calibration all raise IAQ while cutting fan and reheat penalties. Where appropriate, we support UV‑C enhancements and demand‑controlled ventilation strategies to improve cleanliness and reduce unnecessary runtime—all aligned with your building’s occupancy patterns and controls platform.

Industries We Serve in Anaheim

• Medical and clinics: stable temperature/humidity, pressure relationships, and filtration integrity.
• Hospitality and entertainment: quiet operation, reliable comfort, and odor control.
• Retail and mixed‑use: consistent comfort across large floorplates and varying loads.
• Education and public spaces: ventilation and IAQ balanced with budgets.
• Industrial and light manufacturing: process‑sensitive airflow and heat load management.
• Offices and campuses: zoning, scheduling, and BAS integration for productivity and savings.

Proactive Maintenance for AC PRO AHUs

Planned maintenance reduces drift and downtime. Our PMs include coil and drain care, belt tensioning, bearing lubrication, VFD trend checks, economizer verification, sensor calibration, and filter strategy reviews. Expect measurable improvements in static pressure, airflow, and energy consumption, documented after each visit.
