I have a builder-grade bathroom exhaust fan that I want to replace. I’m not sure if this is a simple swap or if it might involve sealing/taping the duct, adjusting or doing some ceiling/drywall cleanup.
Has anyone done this before? What should I check before buying a replacement fan, and what’s the proper way to seal the duct connection so it actually works effectively (no air leaks, moisture issues, etc.)?
Also, if someone is experienced with this, I’d be open to paying for hands-on help so it’s done properly.
The current exhaust fan housing is most likely nailed or screwed in. Read up on wiring home electrical. Make sure you identify the circuit and turn off the circuit breaker. I would use al hvac tape to seal it.
There are plenty of YT videos to help you out if you decide to still do it yourself. The exhaust fan you purchase may not be the same size as the old one. You have to see if you have access to the attic and check if the existing fan is ventilated/ducted to the outside and if it is, check the size of the duct (4” or 6”). When you purchase the new fan make sure the duct size is compatible. Along with what Joe N. Said, you also have to consider your fan can be plain, with a light, and with a heater. All different wiring requirements. Could be an easy job or get complicated.
One of my favorite YouTubers just did a video on this recently that has me very interested in doing a little upgrade at home as well. Like Jose mentioned, depending on what matters to you with the change, it could be a very easy job. I probably won’t do this project super soon, so I can’t offer hands on help, but you might be able to do some initial exploratory work following along with this video that helps confirm if it’s a project you’d feel good doing on your own
