Commercial Whole‑House Fan Installation in Glendale, CA

Commercial whole-house fans use powerful, high-efficiency fans and controlled intake paths to exhaust hot indoor air and draw in cooler outdoor air. In Glendale’s climate, this night-flush strategy can reduce mechanical cooling demand after peak hours, reset building temperatures before occupancy, and improve indoor air quality by removing heat, CO2, and odors rapidly.

Engineered For Commercial Spaces

Our approach adapts the proven concept of whole-house ventilation to offices, retail suites, schools, hospitality, and light industrial buildings. We design rooftop or wall-mounted EC fans, intake louvers, and damper controls to move large air volumes safely and quietly, with attention to acoustics, pressure balance, and fire/smoke control.

• Airflow modeling and duct/plant layout tailored to your floor plan
• EC variable-speed fans for quiet, efficient operation
• Smart controls with temperature, time-of-day, and IAQ strategies
• Balanced intake paths to avoid hot spots and door whistling
• Integration with economizers and BMS where applicable

We also coordinate filtration and intake placement to help minimize outdoor pollutants during operation and use damper logic to seal paths when the fan is off.

• Testing and Balancing: Airflow verification, control tuning, and commissioning report.
• Training and Maintenance: Staff orientation and service plans to keep performance on spec.

Where Whole‑House Fans Make Sense

Whole-house fan strategies are especially effective when evenings cool off and buildings can purge heat quickly:

• Offices and coworking spaces seeking a cooler start each morning
• Retail and restaurants needing rapid odor and heat removal after closing
• Schools and gyms benefiting from high air-change rates off-hours
• Warehouses and light manufacturing with after-hours cooling needs
• Common areas in multi-tenant buildings for night-flush and IAQ refresh

These systems complement, not replace, your air conditioning. During mild evenings and mornings, fans can handle comfort and IAQ efficiently. On hot afternoons, your AC takes over—often starting from a cooler baseline.

Controls, Safety, and Integration

We deploy smart control sequences to run fans only when outdoor conditions and schedules make sense. Interlocks prevent conflicts with mechanical cooling, and damper logic ensures proper intake and exhaust. Where required, we coordinate fire/smoke dampers and signage and observe clearance, anchorage, and access standards.

• EC motors with variable speed for precise airflow and low sound
• Thermal and IAQ sensors with programmable logic
• Optional BMS integration and remote monitoring
• Seismic bracing and OSHA-compliant rooftop access
• Weather hoods, bird screens, and backdraft protection

Frequently Asked Questions

Will a whole-house fan work with my current AC?
Yes. We design sequences so fans run during suitable conditions and your AC handles peak loads. This complementary approach helps improve comfort and can reduce runtime when weather allows.

Is it loud?
We select EC fans, vibration isolation, and duct paths for low sound. Acoustic goals are part of our design and commissioning.

What about code compliance?
We handle Title 24 documentation, permitting, and life-safety coordination. Installations follow local code, manufacturer guidance, and applicable standards.

How long does installation take?
Most commercial projects are completed within a planned window that minimizes downtime, often after hours or on weekends.
