Commercial Whole‑House Fan Installation in Los Angeles

Engineered ventilation that pays off

In our climate, whole‑house fan strategies—often called whole‑building or night‑flush ventilation—can deliver powerful results. By exhausting accumulated heat and bringing in cooler air when outdoor conditions allow, you reduce compressor runtime, stabilize indoor temperatures, and refresh air for healthier occupants. The result is better comfort, improved indoor air quality, and noticeable energy savings, especially when paired with smart controls and demand‑based operation.

#1 AC Guys combines four generations and 80+ years of engineering expertise with deep field experience on complex commercial projects. We design for performance and longevity: correct fan sizing, balanced intake and exhaust, optimized pathways, acoustics, safety, and California Title 24 compliance—so your system works as intended today and remains maintainable tomorrow.

Benefits for commercial properties

• Improved indoor air quality with regular air exchanges that dilute heat, odors, and contaminants.
• Reduced cooling loads by using favorable outdoor air to pre‑cool the building envelope.
• Lower operating costs via high‑efficiency motors, optimized controls, and off‑peak strategies.
• Enhanced occupant comfort with more consistent temperatures and fresh air.
• Supports sustainability goals and can align with ESG and decarbonization initiatives.

Applications include offices, education facilities, fitness studios, retail stores, restaurants, light industrial, and common areas in multifamily buildings.

Our design and installation process

• Assessment and goals: We review floor plans, occupancy, schedules, heat gains, and your comfort/IAQ targets.
• Engineering and sizing: We determine airflow rates, intake area, exhaust placement, and fan curves for efficient, quiet operation.
• Code and documentation: Title 24 strategy, local permitting, and coordination with inspections.
• Equipment selection: High‑efficiency fans, dampers, louvers, filters, and accessories matched to your building and controls.
• Installation: Clean, safe work with proper mounting, vibration isolation, and weather‑tight penetrations.
• Controls integration: Schedules, sensors, interlocks, and building management system (BMS) tie‑ins.
• Testing and balancing: Confirm airflow, noise, and sequences; train your staff on operation.
• Warranty and maintenance: Clear coverage and planned service to protect performance.

Quiet, safe, and code‑ready

We prioritize acoustics and safety. That means right‑sized fans, proper duct/airway design, isolation mounts, and attention to intake/exhaust placement to mitigate noise and vibration. We plan for clear egress, appropriate openings, and coordinate with fire/life‑safety requirements. Weather protection, bird screens, and durable materials keep systems reliable in Southern California conditions.

Smart controls and integration

• Schedules and night‑flush logic based on outdoor temperature differentials.
• CO₂ and IAQ sensors to prioritize healthy air changes when occupancy is high.
• Variable speed operation for quiet, efficient airflow during partial loads.
• BMS integration (e.g., BACnet/Modbus) for centralized visibility and control.
• Safeguards and interlocks to coordinate with HVAC, economizers, and alarms.

We also identify potential utility incentives and local programs where applicable. Rebates and eligibility vary; we help you navigate options and documentation.
