Commercial Dehumidifiers in Fontana, CA

When humidity threatens product quality, comfort, or equipment, you need more than an off‑the‑shelf unit—you need an engineered solution. #1 AC Guys delivers commercial dehumidification tailored to Fontana’s mixed-dry climate, where seasonal heat, ventilation requirements, and process loads can drive moisture spikes. We blend proven engineering methods with practical field experience so your system performs on day one and stays reliable for the long haul.

What We Do

• Design-build commercial dehumidification, from concept to commissioning
• Refrigerant and desiccant systems sized by detailed moisture load calculations
• Dedicated outdoor air systems (DOAS) to control ventilation humidity
• Integration with existing HVAC and building automation systems
• Retrofits, replacements, and performance upgrades for aging equipment
• Preventive maintenance plans and emergency repair

Systems We Work With

• High-capacity refrigerant dehumidifiers for offices, retail, and light industrial
• Desiccant dehumidifiers for low-grain, process-critical environments
• DOAS with energy recovery to manage outdoor air latent loads
• Hybrid strategies that balance latent and sensible control for energy efficiency

Industries We Serve in Fontana

• Warehousing, logistics, and distribution
• Manufacturing and assembly, including process humidity control
• Healthcare, labs, and wellness facilities
• Food, beverage, and cold storage support spaces
• Retail, offices, education, and public venues

Signs You Need Commercial Dehumidification

• Condensation on windows, ducts, or cold surfaces
• Mildew odors, mold growth, or corrosion on equipment
• Warped finishes, damaged packaging, or product rejects
• Unstable indoor humidity despite cooling capacity
• Employee discomfort, poor IAQ, or high absenteeism

Our Process in Fontana

• Site Assessment: We review space use, airflows, ventilation, infiltration, and moisture sources.
• Engineering & Sizing: Moisture load modeling and psychrometric analysis to set targets and capacity.
• System Selection: Refrigerant, desiccant, or DOAS—matched to performance and budget goals.
• Controls & Integration: Sequencing with HVAC, reheat, and BAS to maintain steady RH.
• Installation & Commissioning: Clean installs, functional testing, and documented performance.
• Training & Handover: Staff training, maintenance schedules, and monitoring options.

The Engineering Advantage

As a fourth‑generation family of engineers with 80+ years of experience, we approach humidity control with precision. We validate assumptions, confirm airflow and static pressure, and tune controls so your system holds target RH without energy waste or comfort complaints. Expect thorough documentation and clear communication at every step.

Factory Training and Quality

Our team is factory‑trained at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That background informs our installation standards, diagnostics, and commissioning practices across a wide range of commercial dehumidification equipment. We bring manufacturer‑aligned best practices to every project—large or small.

Maintenance & Reliability

• Scheduled inspections, coil and drain maintenance, and filter management
• Verification of sensors, humidistats, and control sequences
• Desiccant wheel checks, seals, and purge optimization where applicable
• Refrigeration performance testing, leak checks, and superheat/subcooling tuning
• Documentation and trend analysis for continuous improvement

Proactive care prevents downtime, protects interiors and inventory, and keeps energy use in check. When issues arise, we offer swift diagnostics and repairs to restore stable humidity.

Energy, IAQ, and Compliance

We design for efficiency without compromising indoor air quality. Strategies can include dedicated latent removal, sensible reheat, energy recovery, and optimized ventilation. Our team aligns with code requirements and project specifications, helping your facility meet corporate standards and sustainability goals.
