Choosing the Right Whole House Fan Size
Our engineers calculate CFM by multiplying conditioned floor area by 2.5 to 3.0. For a 2,000 sq ft home, this typically ranges from 5,000-6,000 CFM. We ensure adequate attic venting for optimal airflow.
Key Sizing Factors
- Square footage and ceiling heights
- Existing attic vent square inches
- Typical evening temperature drop
- Noise tolerance and fan speed preferences
Installation Day: What to Expect
Our crew arrives with pre-cut materials and a pre-wired fan assembly. A standard retrofit takes four to six hours.
- Protect living areas with sealed plastic sheeting

- Run dedicated electrical to a smart wall switch or Wi-Fi controller
- Balance attic ventilation to maintain warranty compliance
