Commercial AC PRO AHU Repair in Orange, CA

When your commercial AC PRO air handling unit struggles to meet setpoints, produces uneven airflow, or triggers alarms, you need a partner that treats the entire system—not just a part. #1 AC Guys is a family‑owned HVAC company serving Orange, CA, led by fourth‑generation engineers with 80+ years of engineering expertise. We specialize in complex commercial HVAC and deliver durable, code‑minded repairs that elevate indoor air quality and reduce lifecycle costs.

What we repair on AC PRO Air Handling Units

• Fans, motors, bearings, belts, pulleys, and vibration isolation
• VFDs, motor starters, contactors, and electrical components
• Evaporator/coils, reheat coils, valve actuators, and drain pans
• Outdoor air dampers, economizers, and mixing boxes
• Filters, seal integrity, and air leakage remediation
• Temperature, humidity, pressure sensors, and control boards
• Short‑cycling, poor airflow, hot/cold spots, and noise issues

We work on AC PRO‑branded AHUs commonly installed in Southern California commercial buildings and verify performance with post‑repair testing to confirm airflow, temperature, humidity, and pressure relationships.

Our commercial AHU repair process

• Discover: Interview stakeholders, review service history, and inspect safety and access conditions
• Diagnose: Instrumented testing of motors, VFDs, controls, coils, airflow, static pressure, and economizer function
• Explain: Share findings in plain language with options prioritized by risk, cost, and impact
• Restore: Perform repairs using quality parts and precise workmanship; verify and calibrate
• Validate: Post‑repair commissioning checks—airflow, temperature split, humidity, pressure, and control sequences
• Document: Provide a report with readings, photos, and recommendations for reliability and IAQ

Results matter. After repairs, we confirm your AC PRO air handler meets targets, minimizes energy waste, and supports stable indoor conditions across occupied zones.

Preventive maintenance and IAQ upgrades

Unplanned downtime is costly. We offer maintenance plans tailored for commercial AC PRO AHUs to extend equipment life, protect warranties, and control operational expenses.

• Scheduled inspections, lubrication, belt and bearing care, and coil cleaning
• Filter strategy optimization (MERV/pressure drop) for balanced IAQ and efficiency
• Drain pan and condensate management to prevent leaks and microbial growth
• Economizer and damper calibration to meet ventilation needs without overcooling
• Controls tuning, sensor calibration, and sequence verification

Looking to improve indoor air quality? We can integrate practical enhancements and verify results with measurements—because our mission is healthy air for a healthy life.
