Our Installation Process
Attic Assessment
We evaluate your attic size, existing ventilation, insulation, and electrical capacity to recommend the best solution.
Fan Selection
Choose the right fan type and size based on attic square footage, roof design, and cooling needs.
Professional Installation
Expert mounting, electrical connections, and proper sealing to ensure efficient operation and prevent leaks.
Testing & Setup
Complete system testing, thermostat calibration, and operation instructions for optimal performance.
Proper Attic Fan Sizing
Sizing Calculations
Proper fan sizing is crucial for effective attic ventilation. We calculate the required CFM (cubic feet per minute) based on:
- Attic square footage
- Roof pitch and height
- Existing ventilation
- Climate considerations
- Home insulation levels
Common Sizing Guidelines
General recommendations for attic fan capacity based on attic size:
- 1,000 sq ft: 1,000-1,500 CFM
- 1,500 sq ft: 1,500-2,250 CFM
- 2,000 sq ft: 2,000-3,000 CFM
- 2,500 sq ft: 2,500-3,750 CFM
- 3,000+ sq ft: Custom calculation

Frequently Asked Questions
Will an attic fan really lower my cooling costs?
Yes, by reducing attic temperatures from 150°F+ to near outside temperature, attic fans significantly reduce the heat load on your home and AC system, typically saving 10-30% on cooling costs.
Solar vs electric attic fans - which is better?
Both are effective. Solar fans have zero operating costs but depend on sunlight. Electric fans can run anytime but use electricity. We help you choose based on your specific needs and roof exposure.
Do I need additional roof vents with an attic fan?
Yes, attic fans require adequate intake ventilation (soffit vents) to work properly. We assess and can install additional vents if needed for balanced ventilation.
