Commercial Whole-House Fan Installation in Fontana, CA

Commercial whole‑house (whole‑building) fan systems use powerful, efficient fans and controlled intake paths to exhaust hot, stale air and draw in cooler outdoor air—especially effective during Fontana’s evening and overnight temperature drops. The result is faster heat relief, improved indoor air quality, and a meaningful reduction in daytime air‑conditioning demand.

Why whole‑house fans make sense for Fontana businesses

In the Inland Empire’s warm, dry climate, night‑flush cooling and morning purges can remove stored heat from walls, slabs, and equipment quickly—so your AC starts the day with a lighter load. For many facilities, this strategy lowers peak demand charges and extends HVAC life while refreshing indoor air for occupants.

• Cut cooling costs by pre‑cooling the building envelope overnight
• Reduce peak demand and support energy management goals
• Improve indoor air quality with controlled fresh‑air exchange
• Quiet, high‑volume airflow engineered for comfort and productivity
• Integrates with existing HVAC and building automation systems
• Supports Title 24, CALGreen, and ventilation best practices
• Fast installation timelines and low ongoing maintenance

What we design and install

• High‑capacity roof or wall‑mounted exhaust fans (AMCA‑rated), gravity or motorized intake paths, and filtered make‑up air
• Motorized dampers, bird screens, backdraft protection, and weather hoods
• Variable frequency drives (VFDs) for speed control and quiet operation
• Smart controls: night‑flush sequences, temperature and CO₂ sensors, occupancy schedules, lockouts, and alarms
• Integration with BMS via BACnet/Modbus, data logging, and energy monitoring
• Acoustic treatments, vibration isolation, and balanced airflow zoning
• Seismic anchorage and supports per CBC for safety and compliance
• Commissioning, testing, and training for your facility team
