Commercial Humidifier Services in Ontario, CA

When Ontario’s dry seasons and Santa Ana winds lower indoor humidity, static, dust, and material shrinkage rise—hurting comfort, quality, and productivity. #1 AC Guys engineers commercial humidifier systems that stabilize your environment, protect sensitive processes, and align with your energy goals.

Local expertise for Ontario’s climate and industries

From offices and medical clinics to manufacturing, distribution, and tech spaces around Ontario International Airport and Ontario Mills, we understand the Inland Empire’s operational demands. We plan for seasonal swings, infiltration, and process loads so your facility maintains target RH without over‑humidifying.

End‑to‑end engineering for humidification projects

• Assessment and load calculations: envelope, occupancy, ventilation, and process moisture loads.
• System design: ducted, in‑space, or AHU‑mounted strategies to match your HVAC topology.
• Equipment selection: steam (electrode or resistance), ultrasonic, evaporative, or adiabatic high‑pressure systems.
• Water treatment: filtration, softening, RO options to minimize scale and microbial risk.
• Controls and BMS integration: stable setpoints, lockouts, dew‑point tracking, and alarm logic.
• Installation and start‑up: clean, code‑compliant installs with safety interlocks and insulation.
• Commissioning and documentation: calibrated sensors, trend logs, O&M training, and turnover packages.

Systems we service and integrate

We install and maintain electric steam, ultrasonic, evaporative media, and adiabatic humidifiers. Our team integrates humidification with VRF, ductless, split, and rooftop systems, leveraging factory training from Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Haier (China) to ensure responsive controls, balanced airflow, and reliable dehumidification lockout.

Maintenance and reliability

• Scheduled descaling, canister replacement, and ultrasonic transducer care.
• Sanitization protocols, drain and flush verification, and sump inspections.
• Sensor calibration (RH and temperature) and control sequence testing.
• Filter and water treatment checks to extend equipment life.
• Trend analysis to catch drift early and prevent downtime.

Proactive maintenance keeps energy use in check, prevents mineral buildup, and sustains consistent RH—critical for print quality, wood products, electronics, and healthcare spaces.

Health, IAQ, and compliance

Maintaining RH in the 40–60% range can support occupant comfort and indoor air quality while helping reduce static and particulate resuspension. Our designs align with industry best practices and applicable codes, implementing proper drainage, backflow prevention, and materials selection to manage moisture safely.

Budgeting, ROI, and efficiency

We optimize lifetime cost with right‑sizing, smart staging, and water treatment that reduces scale. Controls strategies—like supply‑air dew‑point limits, occupancy‑based setpoints, and economizer lockouts—cut waste while protecting finishes and equipment. We also help identify potential local utility incentives for high‑efficiency measures where available.
