Commercial Dehumidifiers in Pasadena

Purpose-Built Dehumidification for Pasadena Businesses

Moisture doesn’t just create discomfort—it drives mold growth, damages finishes and inventory, disrupts production, and elevates health risks. #1 AC Guys designs commercial dehumidifier solutions that maintain stable relative humidity, protect assets, and support healthy indoor air. Whether your facility needs targeted moisture removal or a fully integrated system tied to your existing HVAC and controls, our engineers deliver dependable results.

When You Need Commercial Dehumidifiers

• Persistent RH above 60%, condensation on glazing or ducts, or musty odors
• Mold, mildew, or corrosion issues impacting finishes, stock, or equipment
• Process-critical spaces (labs, healthcare, archives, printing, woodwork) requiring tight RH
• Comfort complaints in shoulder seasons when cooling is minimal
• Code, warranty, or insurance requirements for humidity control and IAQ

System Options We Engineer

• Refrigerant dehumidifiers: Efficient, versatile units for offices, retail, and mixed-use spaces
• Desiccant systems: High-capacity, low-temperature performance for industrial and specialty needs
• DOAS (Dedicated Outdoor Air Systems): Condition and dehumidify ventilation air per code while reducing latent loads indoors
• Ducted and ceiling-mounted solutions: Space-saving, quiet, and architecturally integrated
• Integrated controls: RH sensors, demand control, and BMS integration for precise, automated performance

Engineered Right the First Time

Our fourth-generation engineering team uses load calculations, psychrometrics, and sequence-of-operations design to size and select equipment correctly. We coordinate filtration, ventilation, latent/sensible capacity, and heat recovery to balance comfort with efficiency. Expect clean sheet-metal work, proper drainage and condensate management, electrical safety, and commissioning aligned with manufacturer specs.

Factory-Trained and Brand-Agnostic

We are trained at the factory level with leading global manufacturers—Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means we understand equipment at its core and can recommend the best-fit technology for your application and budget, not just a single preferred brand.

• 6. Maintenance: Proactive plans to keep RH stable, energy low, and uptime high

Controls, Monitoring, and Compliance

We integrate smart sensors and alarms for continuous RH monitoring, trend logs, and remote alerts. Our designs support local codes and industry best practices while improving indoor air quality. By stabilizing moisture, you reduce mold liability, safeguard finishes, and create healthier spaces for employees and visitors.

Service and Maintenance Programs

Healthy dehumidification depends on clean coils, proper drainage, calibrated sensors, and responsive controls. Our commercial maintenance includes inspection, cleaning, filter changes, condensate checks, and performance reports. Priority response is available for Pasadena accounts that require rapid turnaround and minimal downtime.

Coverage Area

Based in Los Angeles, we service Pasadena and all of Los Angeles County, and we also cover neighboring areas including Orange County, Ventura County, and Western Riverside County. If your portfolio spans multiple sites, we can standardize equipment and service to streamline operations across locations.
