Hey great video! I followed it to replace the very old fan / light / heater in my bathroom with a Broan 655, with no attic access, but with existing wiring and ductwork. If you can possibly get into the attic, I would recommend that and installing the unit from above. Some things I found: Obviously mark both sides of all wire connections before undoing the wire nuts on the old unit. On the new Broan you have to disassemble the unit before you install it, then reassemble it in the ceiling so take pictures / remember how the thing came apart cuz its not obvious where things go when you go to put it together. I carefully cut out the existing metal brackets with a sawzall and framed in 2x4's between the joists to screw the sides of the new Broan unit to. Remember you have to have a big notch in your framed rough opening to allow the house wiring that goes in through the side of the Broan unit to pass through the rough opening when inserting the unit from below. In addition to the snaps and hose clamp provided, I would use aluminum tape to seal the duct hose to the unit as this junction is really leaky without it. Its hard to get the house wiring fished in through the knock out in the side of the unit because it has to make an immediate 90 degree turn so obviously bend this turn into the house wiring before trying to insert it into the unit. All in all the job was tougher than I was expecting for a home owner (me) and I probably would have hired someone to do it knowing that. it took about 3 1/2 hours mostly working with my hands over my head so if you have neck, shoulder or other problems I would say hire someone to do it.

First I thought I'd fix my fans bearing, then I realized that the fan was toast . So I thought new fan, then I discovered it was directly wired to electrical not plugged in. I then noticed the duct work wasn't secured to the fan housing, off to the attic where I discovered the duct travelled 1 foot horizontally releasing into insulation and an unvented attic. I love home repair.

[@leolionz3692]

Reminds me of my old house we had water leaking from the skylight in the master bath it went to the fan and the repair guy said he found over a gallon of water stuck in the vent line which was improperly installed. It went something like that this was around 2011 ish.

When buying a new fan (0:10), don't you also have to check the duct size? What if you have a 3" duct and you buy a fan for a 4" duct? I'm sure there are lots of other details that could be covered for specific cases, but this video does a helpful job of covering the basics!

[@aquaticnstuff7666]

honestly you can use 3in fan with 4in duct it's fine; but 4" fan with 3" duct is not allowed by IRC code based on my limited recollection.

[@daneasterly4063]

That was my situation, the new fan had a 4 inch duct and the existing ductwork 3 inches but fortunately Lowe's sold an adapter

[@pablopiquante3227]

I was thinking the same thing! If you have a new fan with a 4 inch duct and the existing line is only a 3", can you just put in an adapter? It might just be a bit louder but still work?

I am afraid that it might cost me a lot of money to fixed the problem. Please provide me with some suggestions. I am older and I am in no way a handy person.

[@kevenmelara227]

great video

[@garen_g2956]

Great video with simple, easy to understand straightforward explanations. Is that ok that the placement of the duct's end in the outside wall is higher than the fan itself? Will not the condensed water stay in the duct that way? I already have a 4” duct connected to the kitchen fan and it is running about 10” above the place where I’m planning to install the bathroom fan. Can I connect bathroom fan to that duct? Thank you.

[@Isis-wm4po]

Don't forget to get your duct at a length where you can allow the water to pool at a spot that is not your fan (i.e. the electrical), and I would recommend to everyone to check what you have done after you have been using it. I look at my seals, seams, and all about once a month for everything. You never know when a small mistake overlooked when installed will cause a great problem down the road. Better to fix it before it causes a greater issue. The water pooling in the duct will be easier to repair than one that allows water that may come in to run all the way to the fan. Be it electrical or where you have it secured, you want to inspect it regularly.

7:22 you should probably put some insulation over the top of that fan also. And, in addition to that, if you buy some really fancy fan, some of them aren't "contact rated" with insulation, so, the only way to insulate those is to build a box or something around them.
