Exhaust fan replacement costs

Exhaust fans are rated by how much air they can move, which is measured by cubic feet per minute (CFM). Typically, you’ll need a fan that moves one CFM of air per square foot of your bathroom. The cost of replacing your exhaust fan greatly depends on the size of the unit you'll need for your bathroom.

Here’s what you can expect to pay for an exhaust fan replacement depending on the CFM grade:

In addition to the CFM rating, exhaust fan replacement costs depend on the type of fan, as well.

Additional exhaust fan costs

If you're replacing your exhaust fan or installing a new system, you may need a professional. Labor costs typically range from $200 to $800, depending on whether electrical work, ductwork, venting and potentially even roofing are required for the fan installation.

Additionally, you might need an HVAC or roofing permit to install a new system. HVAC permits can cost anywhere from $250 to $400, and roofing permits range from $70 to $250.

Can you DIY an exhaust fan replacement?

If you are thinking about replacing your exhaust fan, you could potentially do it yourself. Typical replacements usually take 30 minutes to an hour, and you typically only need a key saw, a flat-head or Phillips screwdriver, brackets and spackle for roof repair.  However, some installments require more detailed work, like electrical, ductwork, venting and roofing, so it might be worth calling a contractor.

When should an exhaust fan be replaced?

Most exhaust fans last up to 10 years, but kitchen and attic fans can last around 12 years. Before your exhaust fan breaks down completely, there will be some signs that it needs to be repaired or replaced.

One big sign is when the room starts to feel stuffy or has an odor. This could be caused by your fan working slower because of electrical or HVAC problems. Also, if you hear a strange noise coming from your system or you see mold, mildew or wood rot, it might be time for a replacement.

Does your home warranty cover exhaust fan repair or replacement?

Many home warranty companies offer coverage on repairs and replacements for exhaust fans in their systems plan or as an add-on. However, some plans only include kitchen exhaust fans, while others only cover attic or bathroom fans.

Also, some home warranties only offer protection for newer fans, certain types and certain repairs. You may not be covered if you have an older or professional-grade exhaust fan. So, double-checking your policy may be a good idea.
