Commercial Humidifiers in Los Angeles

In Southern California’s dry climate, precise indoor humidity isn’t a luxury—it’s a building necessity. At #1 AC Guys, our fourth‑generation, family‑owned team brings 80+ years of engineering experience to design, install, and maintain commercial humidifier systems that keep your occupants healthier, your finishes protected, and your operations stable. Our mission is simple: healthy air for healthy life, achieved through smart, reliable humidity control tailored to your facility.

Why Commercial Humidity Matters

Targeting 40–60% relative humidity supports respiratory health, reduces airborne particle spread, and combats static that threatens electronics and production quality. Proper RH also protects woodwork, artwork, paper, textiles, and musical instruments, while enhancing comfort and productivity in offices, classrooms, and clinics.

Engineered Solutions for Every Building

We start with a detailed site assessment: envelope and infiltration review, occupancy and process loads, outside air volumes, psychrometric targets, and water quality. Then we model options for capacity, energy, maintenance, and controls to deliver a system that meets Title 24, local codes, and your budget. Whether it’s a new build, tenant improvement, or retrofit, we integrate seamlessly with your AHUs/RTUs, DOAS, and VRF systems from leading manufacturers we’re factory‑trained on, including Fujitsu and Mitsubishi Electric.

Systems We Design & Install

Clean Steam (electrode, resistive, gas-fired): High-accuracy RH control for healthcare, labs, archives, and data environments. Options for stainless dispersion tubes, short absorption manifolds, and high-pressure steam grids.
Evaporative & Adiabatic: High-efficiency humidification with the bonus of sensible heat reduction—ideal for large AHUs and energy-conscious retrofits. Includes media, spray, and high-pressure systems with integrated droplet separators.
Ultrasonic: Low-energy, fine mist for spaces requiring quiet operation and tight control. Great for museums, print rooms, and specialty spaces.
Point-of-use & Duct-mounted: From fan-powered units serving critical rooms to duct-injection arrays for centralized air handlers, we size for absorption distance and air velocity to prevent carryover.

Water Treatment, Hygiene & Materials

We evaluate make-up water and specify filtration, softening, and RO where required to protect equipment, reduce scale, and maintain hygiene. For steam systems, we select stainless or corrosion-resistant wetted parts; for adiabatic systems, we design proper drains, UV, and biocide strategies as needed. Our designs prioritize IAQ and maintainability.

Controls, BMS & VRF Integration

We deliver BACnet/Modbus integration, room and duct RH sensors, dewpoint safety, discharge high-limit controls, and supply air temperature coordination to prevent over-humidification. For VRF and DOAS, we coordinate reheat and ventilation sequences so humidity targets are achieved without comfort penalties.

Maintenance & Compliance

Predictable performance requires proper service. We offer planned maintenance programs covering canister/boiler replacement, scale management, sensor calibration, dispersion assembly cleaning, and water treatment checks. Our team documents performance, helps with Title 24 acceptance testing, and supports IAQ programs and commissioning requirements.
