ProfessionalExhaust Fan Replacement

A bathroom exhaust fan that rattles, hums, or barely moves air is doing nothing to protect your ceiling from moisture damage. We pull the old unit, install a quiet, properly-rated replacement, and verify the duct is sealed so the humid air actually goes outside — not into the attic.

How it works

1

Remove the old fan

We cut power, pull the grille and motor, disconnect wiring, and inspect the duct connection before the new unit goes in.

2

Install and wire the new fan

We set the new housing into the ceiling opening, secure it to the joist, connect the wiring, and re-seal the duct transition.

3

Test and confirm

We restore power, run the fan to check the CFM performance, listen for excessive noise, and install the grille cover.

We can help

Problems we fix

  • Duct disconnected in the attic, blowing humid air directly onto insulation instead of outside
  • Undersized fan — old unit rated for 50 CFM where 110 CFM is now required
  • Wiring connected directly to the fixture without a junction box, a code violation
  • Grilles covered in lint that choke airflow and make the motor work harder

Good to know

Exhaust Fan Replacement — FAQ

What CFM rating do I need for my bathroom?

The general guideline is 1 CFM per square foot of bathroom floor area. A 60 sq ft bathroom needs at least a 60 CFM fan; most pros recommend 10–20% above the minimum.

Can you install a fan-light combo?

Yes — we install fan-only, fan-light, and fan-light-night-light combos. Just tell us what you want and we'll confirm the existing wiring supports it.

My bathroom exhaust fan leads to a flex duct in the attic — is that a problem?

Only if it's disconnected or improperly terminated. We check that the flex duct runs to the soffit or roof cap and is properly sealed at both ends.
