Bathroom Exhaust Fan Installation Cost in Bellevue, WA

A bathroom exhaust fan that's noisy, weak, or dead is one of the most common electrical service calls we get in Bellevue. Washington code requires mechanical ventilation in all bathrooms without operable windows. Replacing an existing fan costs $150–$275. Installing a fan where there is none — including a new duct run — runs $300–$550.

Replacing an Existing Bathroom Fan

If there's already a fan in the ceiling with wiring and a duct run in place, replacement is straightforward. We remove the old unit, install the new fan in the same location, connect the existing wiring, and verify the duct connection. Cost: $150–$275 depending on attic access and whether the duct needs any adjustment. Most Bellevue homes have accessible attic space above bathrooms.

Fan + Light Combo Units

Most modern replacement fans include an integrated light, eliminating the need for a separate ceiling light fixture. If your current fan is fan-only, we'll need to add a switched circuit for the light portion, which adds a small amount to the job. We confirm your wiring situation before starting.

Humidity-Sensing and Timer Fans

Humidity-sensing fans automatically run when moisture levels rise — popular in Bellevue master bathrooms. Timer fans run for a set period after you leave the room. Both install for the same labor cost as a standard fan swap: $150–$275. The fan itself costs more, but the installation is identical.

New Fan Installation (No Existing Fan)

Installing a fan in a bathroom that has no existing exhaust — sometimes found in powder rooms and older half-baths — requires running a new circuit and a duct to the exterior. Cost: $300–$550 depending on duct routing distance and attic access. Washington code requires the duct to terminate outside, not into the attic.

Cost Summary — Bellevue WA

  • Replace existing fan (same location): $150–$275
  • Humidity-sensing or timer fan: $175–$300

Our bathroom fan was rattling badly and barely moving air. They replaced it with a quiet Broan unit that actually works. In and out in about an hour.
