Commercial Dehumidifiers in Los Angeles

Why Commercial Dehumidification Matters in Los Angeles

Los Angeles businesses face unique humidity challenges: marine layers near the coast, heat waves inland, and seasonal rains that spike building moisture. Elevated relative humidity drives mold growth, damages finishes and inventory, degrades electronics, and undermines comfort and productivity. Precise humidity control safeguards air quality, protects assets, and keeps your facility compliant with ASHRAE and Title 24 performance requirements.

Our Difference: Four Generations. 80+ Years. Factory-Trained.

#1 AC Guys is a fourth-generation, family-owned HVAC company serving Los Angeles County and neighboring Orange, Ventura, and Western Riverside Counties. Our engineers and technicians are factory-trained by leading manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China). We specialize in large and complex commercial projects—new construction, design–build, and challenging retrofits—always guided by our mission: healthy air for a healthy life.

End-to-End Services

• Engineering & Design: Psychrometric analysis, load calculations, dew point targeting, and system selection (refrigerant vs. desiccant). Integration with DOAS, hot-gas reheat, energy recovery, and BMS platforms.
• Installation & Retrofit: Duct design, condensate management, vapor barriers, insulation, corrosion-resistant materials, and precise commissioning with data-logging.
• Repair & 24/7 Emergency Service: Rapid diagnostics for compressors, blowers, heaters, sensors, and controls. Replacement parts and priority response for critical facilities.
• Planned Maintenance: Coil and drain cleaning, filter programs (MERV 13+), sensor calibration, desiccant reactivation inspection, and performance reporting.

Systems We Deploy

• High-Capacity Refrigerant Dehumidifiers: Ducted or rooftop integration with hot-gas reheat for neutral-supply air.
• Desiccant Dehumidifiers: For low dew points, cold storage, process environments, and natatoriums; gas or electric reactivation.
• DOAS + Reheat: Dedicated outdoor air systems that deliver ventilation, latent control, and compliance with ASHRAE 62.1 and Title 24.
• Controls & BMS: Smart humidistats, staged or inverter control, demand response readiness, and BACnet/Modbus integration.

Applications We Serve

• Offices, schools, and multi-tenant buildings
• Healthcare, labs, and clean spaces
• Hotels, spas, gyms, and indoor pool rooms
• Restaurants, supermarkets, and food processing
• Warehouses, manufacturing, and distribution
• Data rooms, telecom, and electronics
• Museums, archives, and specialty storage

Code, Safety, and Quality

Our designs are aligned with ASHRAE 55/62.1/90.1 and California Title 24. We specify UL/ETL-listed equipment and follow NFPA and OSHA best practices. For indoor pool rooms and corrosive environments, we use coated coils, sealed enclosures, and proper vapor management to prevent structural damage.

Energy Efficiency and Incentives

Right-sizing and hot-gas reheat, demand-control ventilation, and energy recovery drive down operating costs. We can help you evaluate potential utility incentives and programs from LADWP, Southern California Edison, and regional agencies, as well as strategies to support ESG goals and lifecycle cost reductions.

Our Process

1. Assessment: On-site survey, data-logging RH/temperature, and review of building use and constraints.
2. Design & Proposal: Clear options with capacities, diagrams, controls strategy, timelines, and warranties.
3. Installation: Clean, safety-first execution with commissioning checklists and client training.
4. Support: 24/7 service and preventive maintenance to protect uptime and efficiency.
