Commercial HVAC Sensor Calibration in Orange, CA

Why precise calibration matters for Orange commercial buildings

When sensors drift, your building pays the price: unstable temperatures, poor humidity control, nuisance alarms, low IAQ scores, and rising energy bills. Accurate temperature, humidity, CO2, pressure, and airflow data enables better setpoint control, correct economizer logic, proper ventilation rates, and smoother VAV and RTU operation. In the City of Orange—where comfort, compliance, and tenant satisfaction drive value—calibration is a fast ROI.

What we calibrate and verify

• Temperature sensors: duct, space, discharge, mixed air, and outdoor
• Humidity sensors and transmitters
• CO2 and IAQ sensors for ventilation control
• Static and differential pressure sensors (duct, filter, room pressurization)
• Airflow stations and VAV box sensors
• Thermostats and control probes (RTD/thermistor)
• Refrigeration circuit sensors (where applicable)

We address offset and span errors, confirm placement and shielding, review wiring and grounding, and validate readings against reference instruments under stable conditions.

FAQs

How often should we calibrate sensors?
Many commercial facilities choose annual calibration; critical spaces may require more frequent intervals based on compliance or usage.

What are signs our sensors need attention?
Frequent overrides, drifting setpoints, inconsistent zone temperatures, unexpected humidity swings, and ventilation alarms often indicate sensor inaccuracies or placement issues.

Can you work alongside our building automation contractor?
Yes. We collaborate with your controls provider to align calibration changes with sequences, setpoints, and trend strategies.
