Commercial Sensor Calibration in Glendale for AC PRO and Advanced HVAC Systems

Precision You Can Bank On

When HVAC sensors drift, your building automation makes decisions on bad data—comfort suffers, IAQ declines, and utility costs climb. Our engineers diagnose and recalibrate the sensors that matter most to commercial performance, including temperature, relative humidity, static and differential pressure, CO2, VOC, and airflow. We support AC PRO equipment and components widely used across Southern California, as well as complex VRF and controls ecosystems.

What We Calibrate

• Temperature sensors (RTD, thermistor) for zones, discharge air, mixed air, and refrigeration circuits
• Humidity sensors and dew‑point transmitters for accurate comfort and mold mitigation
• CO2 and VOC sensors for demand‑controlled ventilation and indoor air quality strategies
• Static and differential pressure sensors across filters, ducts, and clean spaces
• Airflow stations and pitot arrays for VAV/VVT and makeup air systems
• Refrigerant and condenser sensors for VRF/VRV, rooftops, and split systems

We calibrate sensors within AC PRO‑supplied rooftop units, air handlers, heat pumps, and split systems, as well as networked controls, thermostats, and field devices tied to your BMS.

Our Commercial Calibration Process

• Assessment: Review system design, sequences of operation, recent alarms, and trend logs to target the highest‑impact points.
• Reference Instruments: Use laboratory‑calibrated reference tools and best‑practice methods aligned with ASHRAE and SMACNA guidance.
• Adjust & Tune: Set offsets at the controller or device, update firmware where applicable, and verify scaling and mapping in the BMS.
• Functional Testing: Confirm economizer logic, DCV response, fan curves, and safety interlocks behave correctly under updated sensor values.
• Documentation: Deliver a clear calibration report with as‑found readings, adjustments made, final values, and recommendations.

Need minimal disruption? We schedule nights, weekends, or break periods to keep your business running while we tune critical points to spec.

Brand and System Expertise

Our 4th‑generation family business brings 80+ years of engineering experience to commercial HVAC. We are factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). This training, combined with deep field practice, helps us calibrate sensors in VRF/VRV systems, ductless and ducted mini‑splits, and integrated control networks—working seamlessly alongside AC PRO equipment and parts installed throughout Glendale and greater Los Angeles.
