Commercial HVAC Sensor Calibration in Los Angeles

Reliable sensor data is the backbone of every efficient commercial HVAC system. If temperature, humidity, pressure, CO2, or airflow sensors drift, your BAS/BMS makes poor decisions—leading to hot/cold calls, poor air quality, higher utility bills, and premature equipment wear. #1 AC Guys provides precision calibration and functional verification designed for demanding commercial environments in Los Angeles and nearby counties.

What we calibrate and verify

• Temperature sensors: room, return, supply, mixed, duct averaging, immersion
• Humidity sensors and dew point probes
• CO2 and VOC sensors for IAQ and demand control ventilation
• Static and differential pressure sensors: duct, filter, and space pressurization
• Airflow stations, VAV flow sensors, and pitot arrays
• Economizer and outdoor air sensors (OAT, OAH), enthalpy
• Refrigeration and hydronic sensors: thermistors, RTDs, pressure transducers

We service rooftop units, air handlers, VAV/VVT systems, VRF/mini‑split networks, and integrated BAS/BMS/EMS platforms—compatible with systems that use AC PRO components.

Why calibration matters

• Comfort and IAQ: Accurate readings keep spaces stable and support healthier indoor air.
• Energy savings: Correct sensors reduce short cycling, reheat, and simultaneous heat/cool.
• Compliance: Documentation supports audits, commissioning, and preventive maintenance.
• Longevity: Balanced operation lowers stress on fans, compressors, and valves.

Our process for dependable results

• Site assessment: Review equipment schedules, controls sequences, and access constraints.
• Reference setup: Use industry‑standard, well‑maintained references; NIST‑traceable options available upon request.
• Calibration and adjustment: Compare, correct, and stabilize each sensor point; update controller offsets where applicable.
• Functional verification: Confirm BAS/BMS reactions, alarms, economizer logic, and safeties.
• Reporting: Deliver clear pass/fail results, as‑left readings, and recommendations.

For mission‑critical areas—healthcare, labs, data rooms—we can schedule off‑hours calibration and staged work windows to minimize downtime.

Industries and facilities we serve

• Office campuses and high‑rises
• Healthcare clinics and outpatient facilities
• Laboratories and life sciences
• Education and public buildings
• Hospitality and retail
• Industrial, warehouses, and logistics

AC PRO compatibility

We calibrate sensors and verify operation on commercial systems that incorporate AC PRO components, rooftop units, and controls. Our team ensures readings align with the design intent so your equipment operates efficiently and reliably.

Note: AC PRO is a trademark of its respective owner. #1 AC Guys provides independent service and compatibility support.

Engineered expertise you can trust

We are a family of engineers in our 4th generation with 80+ years of engineering experience. Our specialists have trained at manufacturer facilities of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That depth of engineering and field experience helps us solve complex commercial challenges—from chronic hot/cold zones to unstable economizer logic—fast and correctly.

Signs you need sensor calibration

• Frequent comfort complaints despite recent “tune‑ups”
• Unexpected utility bill increases
• BAS trends show oscillation or conflicting commands
• IAQ alarms without a verified source
• Filters or coils look clean, but airflow readings don’t make sense
• New equipment isn’t meeting design setpoints

What you receive

• Documented pre/post readings and offsets
• Prioritized recommendations (repair, replacement, re‑commissioning)
• Trend suggestions to confirm stability over time
• Maintenance intervals matched to your environment and usage
