Healthy indoor air isn’t optional—it’s essential for productivity, product quality, and comfort. In Downey and across Los Angeles County, #1 AC Guys helps commercial facilities get humidity right the first time with Carrier commercial humidifiers precisely selected, installed, and maintained to your building’s needs.

What we design, install, and service

• Design‑build and retrofit of Carrier commercial humidifier systems: steam, evaporative, and atomizing.
• Load and psychrometric calculations to target ASHRAE‑recommended humidity ranges.
• Steam dispersion design: injection tubes, dispersion panels, and proper non‑condensing distances.
• AHU and duct integration, including DOAS and outside‑air pretreatment strategies.
• Controls and BMS integration (BACnet/Modbus), humidistats, and RH sensor calibration.
• Water quality management: RO/DI options, scale mitigation, drain and flush cycle optimization.
• Electrode canister and resistive element service, gasket and hose replacement, leak prevention.
• Planned maintenance programs that extend life and reduce energy use.

We service new and existing Carrier humidifiers and integrate them seamlessly with Carrier air handlers or mixed‑brand HVAC systems to ensure stable, consistent relative humidity.

Our proven process

• Discovery and site assessment: verify loads, infiltration, ventilation, envelope, and space use.
• Solution design: equipment selection, dispersion layout, electrical and condensate routing, and controls sequences.
• Clear proposal: scope, timeline, responsibilities, and transparent, itemized pricing.
• Professional installation: clean work practices, safety compliance, and minimal disruption.
• Commissioning: sensor placement, tuning, trending, and documented performance verification.
• Training and handoff: simple instructions for facilities staff, alarms, and maintenance schedules.
• Ongoing maintenance: predictive checks to prevent nuisance faults and downtime.

An engineering legacy you can measure

We’re a 4th‑generation family business with 80+ years of engineering experience. Our team is trained at manufacturer facilities Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That depth shows up in the details—correct trap sizing, sensor placement, psychrometric accuracy, and controls that eliminate simultaneous humidification and dehumidification. Expect thorough commissioning reports and RH trending that prove the results.

Industries and spaces we support

• Healthcare, dental, and clinics seeking stable RH for patient and equipment protection.
• Data rooms, labs, and clean spaces where static and contamination must be minimized.
• Manufacturing, printing, woodwork, and textiles requiring process‑critical humidity.
• Offices, education, retail, hospitality, and houses of worship focused on comfort and IAQ.

Maintenance that prevents downtime

Humidity equipment needs proactive care to stay efficient and reliable. Our programs are designed to catch small issues before they become outages.

• Seasonal start‑up/shutdown, safety checks, and drainage verification.
• Electrode canister replacement and descaling to maintain output and efficiency.
• Gasket, valve, and hose inspection; leak tests; condensate trap verification.
• RH sensor calibration and controls tuning for accurate setpoint tracking.
• Water quality testing and treatment adjustments to reduce mineral buildup.

Smart controls and energy optimization

We integrate Carrier humidifiers with your building automation system to deliver stable comfort with less energy. Strategies include demand‑based setpoints, economizer coordination, dew‑point control, and lockouts that prevent wasted reheat. You get actionable alarms, runtime analytics, and RH trends that make managing the building easier.
Result: fewer callbacks, better comfort, and predictable operating costs.

Codes, standards, and documentation

Our designs and installations align with applicable standards, including ASHRAE 55 (thermal comfort), ASHRAE 62.1 (ventilation and IAQ), ASHRAE 90.1 (energy), and ASHRAE 170 for healthcare where applicable. We support local permitting in Downey and across LA County, provide stamped submittals when required, and deliver complete O&M manuals and training.

Service area

Headquartered to serve Downey and all of Los Angeles County, we also cover nearby Orange County, Ventura County, and Western Riverside County. If you manage multiple facilities, we can coordinate schedules and standardize equipment across sites.
