WHAT AFFECTS PRICE
Factors that influence cost
Several variables determine where your quote falls within the typical range.
Foundation type
Basements, crawl spaces, and slabs each require different approaches and materials.
Number of suction points
Larger homes or homes with complex foundations may need multiple suction points for effective depressurization.
Crawl-space work
Installing and sealing a vapor barrier over a crawl space adds labor and material cost.
Pipe routing
Interior routing through closets or finished spaces may cost more than a straightforward exterior run.
Electrical requirements
If a dedicated outlet is needed for the fan, an electrician may be required.
Post-installation testing
Some professionals include a follow-up test; others charge it separately.
System warranties
Fan warranties and system guarantees vary by provider and may affect the total price.
