Commercial Whole-House Fan Installation in Pasadena, CA

When Pasadena days run hot, a commercial whole-house fan system can purge stored heat rapidly, bring in cooler evening air, and reduce your building’s reliance on mechanical cooling. At #1 AC Guys, we engineer and install turnkey whole‑building fan solutions that cut peak loads, improve indoor air quality, and support a healthier environment for staff and customers—aligned with our mission: healthy air for a healthy life.

What a Commercial Whole‑House Fan Does

Unlike small exhaust fans, a commercial whole‑house fan moves large volumes of air to flush heat and pollutants through controlled intake and exhaust pathways. Used during cool morning and evening hours, it pre‑conditions your space, reduces AC run time, and can extend equipment life while improving comfort.

• Energy savings by shifting cooling to off‑peak hours
• Fast cool‑down after hot days and weekend shutdowns
• Better indoor air quality by diluting CO2, VOCs, and odors
• Lower strain on rooftop units and splits
• Quiet operation with acoustic treatment and smart speed control

Engineer‑Led Design and Installation

• Assessment: On‑site survey, envelope review, intake/exhaust opportunities, and safety checks.
• Calculations & Modeling: Airflow, pressure, sound, and heat‑load impact to right‑size fans and ducts.
• Equipment & Controls: High‑efficiency fans with multi‑speed or VFD control, economizer logic, BMS tie‑ins, and ventilation schedules.
• Structural & Acoustics: Mounting details, vibration isolation, and noise mitigation for occupied areas.
• Permitting & Submittals: Title 24 documentation, plans, and coordination with local AHJs in Pasadena.
• Installation: Clean, code‑compliant work with fire/smoke considerations and tested airflow paths.
• Commissioning: Verification of airflow, balancing, controls programming, and staff training.
• Turnover Package: As‑builts, O&M manuals, warranty information, and maintenance plan options.

Code, Compliance, and IAQ

Our designs are prepared to meet California Title 24 energy standards and applicable ventilation requirements (e.g., ASHRAE 62.1 guidance), as well as local Pasadena code and noise ordinances. We address fire and life‑safety clearances, proper makeup air, and secure electrical work. Where needed, we incorporate filtration strategies and CO2‑based ventilation control to keep air clean and comfortable.

Ideal Applications

• Office buildings, creative spaces, and co‑working environments
• Retail and restaurants (back‑of‑house and dining comfort strategies)
• Schools, houses of worship, and community facilities
• Light industrial, warehouses, and distribution areas

Integration With Your Existing HVAC

We coordinate whole‑house fans to complement—never fight—your cooling strategy. Controls can lock out fan operation during peak outdoor temperatures, enable night flushing on a schedule or via sensors, and interface with BMS platforms. The result: lower peak demand, improved comfort curves, and extended HVAC life.
