When outside temperatures soar, an efficient attic fan can drop interior attic temperatures by up to 30°F, protecting roofing materials and cutting HVAC bills. But how much should you budget to replace an under-performing unit? CountBricks has compiled this in-depth breakdown of attic fan replacement cost so you can plan with confidence, request precise estimates through CountBricks.com, and keep your home comfortable year-round.
Across the residential projects logged inside CountBricks Estimate Cloud, the typical attic fan replacement cost falls between $450 and $950. That range includes labor, disposal of the old fan, and a mid-range 1,500–2,000 CFM unit. Final pricing always depends on a handful of variables that every homeowner should understand before approving a quote.
• Fan capacity and brand specification: Higher CFM and smart-control features drive material pricing upward.
• Roof or gable mounting style: Roof-mounted fans require shingle removal, flashing, and weatherproofing, adding labor hours.
• Electrical accessibility: Existing wiring near the installation zone reduces time on site, while new circuits add both material and electrician costs.
• Attic accessibility: Narrow hatch openings, steep roof pitches, or insulation upgrades may require extra prep work.
• Permit jurisdiction: Some municipalities mandate mechanical permits; CountBricks Pro Desk automatically flags local fees during estimate creation.
1. Basic 1,000 CFM gable fan: $120 – $180
2. Mid-range 1,500 CFM roof fan with thermostat: $200 – $320
3. Solar-powered 1,800 CFM roof fan: $350 – $550
4. Smart Wi-Fi 2,000 CFM hybrid fan: $380 – $650

Replacing an outdated attic fan is not simply a maintenance expense; it is an energy-efficiency upgrade that can pay back in two to four summers.
• Lower cooling bills: Studies inside CountBricks Energy Lab show an average 8 % drop in whole-home electricity usage when a correctly sized fan is installed.
• Roof longevity: By venting excess heat, shingles stay up to 20 °F cooler, extending roof life by three to five years.
• Comfort and indoor air quality: Reduced attic humidity limits mold growth and musty odors that seep into living spaces.
Many homeowners wonder whether to tackle the job themselves. The CountBricks Safety Index identifies three primary risks:
1. Roof penetration errors leading to leaks
2. Improper wiring that voids home-insurance coverage
3. Undersizing or oversizing the fan, which cancels energy savings
For these reasons, 87 % of CountBricks residential clients choose professional installation, resulting in warranty coverage on both parts and labor.
