Angi and HomeAdvisor are corporate siblings, and their attic fan repair figures are identical; matching figures alone do not establish independent corroboration. Angi ties its 2026 national average to 1,495 verified projects from Angi Pros; HomeAdvisor’s page states no project-count basis. HomeGuide is a separate owner: it reports a national average of $325, an average range of $100 to $500, a minimum of $60 and a maximum of $1,000; these are separately published figures, and the pages state no shared sourcing.
Repair cost by repair type
Motor work is the big-ticket repair at $150 to $650 on both pages that publish it, while blade replacement runs $60 to $200.[1][3]

Attic fan repair cost by repair type, with each source’s scope reported as published: HomeAdvisor’s electrical figure includes labor and its belt/switch figure is parts-only, while HomeGuide’s belt/switch figure includes one hour of labor. The motor, thermostat and blade ranges are identical across Angi and HomeGuide (HomeAdvisor does not publish comparable per-repair totals); Angi and HomeAdvisor are corporate siblings, and the pages state no shared sourcing with HomeGuide – matching figures alone do not establish independent corroboration.

Labor costs
Angi puts attic fan repair labor at $40 to $120 per hour, handled by electricians, HVAC technicians or experienced handypersons.[1] HomeAdvisor and HomeGuide both put electrician rates at $50 to $130 per hour, with HomeGuide noting a $75 minimum call-out fee; these are separately published figures, and the pages state no shared sourcing.[2][3]
Whole-house fan repairs
HomeAdvisor puts whole-house fan repairs at $250 to $350, though its own page caps them at $650 in one place and $670 in another; both versions are reported as published.[2] HomeAdvisor puts whole-house fan replacement at $1,200 to $1,800 on average with a total range of $700 to $3,000, while HomeGuide puts a new whole-house fan installation at $600 to $2,200; each figure is reported with its source.[2][3]
Repair or replace the fan
The siblings diverge from HomeGuide on replacement context: HomeAdvisor puts a new attic fan installed at $625 on average, ranging from $370 to $920, while HomeGuide puts new attic fan installation at $300 to $900; both versions are reported as published.[2][3] HomeAdvisor adds that an upgrade to solar power or a new electrical circuit adds $500 to $700.[2]
DIY or hire a pro
HomeGuide calls belt or switch replacement a relatively simple DIY repair that saves $50 to $80 or more in labor, and both HomeAdvisor and HomeGuide suggest checking the circuit breaker before calling anyone.[2][3] Angi draws the line at electrical repairs, which it says pose real safety hazards and belong to a licensed electrician.[1] For homeowner-replaceable vent covers and turbine caps, the Roof Vents category at Home Depot carries the common sizes (non-affiliate link, provided for convenience).
