I like my noisy units since they cover the strange noise coming from the toilet area during evacuation.

Keep in mind that a quiet fan may not be ideal for example in a guest bathroom off a kitchen where others might gather. Loud fans drown out offensive noises.

Very good video. Most DYI videos go through the process and act like it's nothing to install. This gentleman showed problems and how he overcame them. Thank you for a realist install.

Looks clean! Crazy how switching out your bathroom fan gives it a whole new look!

I got quotes for this a few years back. Anywhere from 1-2000 dollars. I said nope I'll diy. I wanted to replace our light fan combo in the bathroom during our renovation. Watched a bunch of videos and finally gave it a go and opened it up. Had to cut a large portion of drywall and to my surprise. It was so old it was nothing like any of the videos. After a few weeks of messing with it without the proper tools I asked my friend who was an electrician for help. He had previously declined the job because they suck. He fixed it in 10 seconds. I felt stupid but that's why he's a pro. I still paid him for helping me get out of a jam. Total pain in the rear but turned out nice.

I used Broan humidity sensing variable speed fans. They require 6" ducting for 120 CFM and the <0.3 sone rating. I used hard smooth walled ducting with short flex sections where necessary for maximum flow per the installation instructions included with the fans. All the previous units had 3" flex hose, so there was a whole lot more work involved, and all but two vent to the wall, not the roof. The fans are hard to hear even at 120 CFM because they're so quiet. Mine are variable speed and run at 30 CFM all the time to ensure fresh air is circulating in the house with four fans in four bathrooms with tubs/showers. Two other bathrooms got 80 CFM fixed speed fans on 4" ducting and run on timers. I am quite happy with the results.

I'm so glad to see you still using the outside vent. You have no idea how many people just let it vent into the attic.
Good job!

5:00 Just FYI, that cable clamp is actually meant for MC (Metal Clad) cable, not NM. You can tell because the diameter hole of your cable clamp is smaller than the actual NM type. NM cable camps have an opening that is just about as wide as the threads to allow for wider cables like 12/3.

The tricky ones are the main floor bathroom where you have access to the exhaust vent or hose. In my last house had to take it out half the ceiling to change it. Bathroom fans should be standardized to all have the wiring and vents in the same place. Not sure about these days, but the fans I had, were discontinued so couldn't just swap out an old one with a new one.

When we bought our house, the downstairs bathroom fan sounded like WWII fighter idling on the flight line. It was so loud, you could tell someone was in the bathroom from anywhere in the house. When we renovated that bath, we swapped out the fan for the exact model you show here, and it’s so much nicer. The only issue is that occasionally the fan shuts off in the 10 seconds it takes you to go from the door to sitting on the toilet, even though it’s set for 30 minutes of non-activity. You have to wave your hand to get it to kick back on, then it’s fine.

Thanks for your video! I like that you explain each step and show it, so viewers know what they need to do or don’t . This is good for homeowners that want to DIY if they can’t afford to pay someone and have some knowledge of every detail before they get to it, also don’t do if they can’t, better pay someone to do it.
I will check your other videos

[billdotpilot]

Great video. I just subscribed and watched several more.
2 things. The strain relief you used is designed and listed for use with MC cable. The small hole is designed to stop the MC cable jacket from entering the JBox. The strain relief designed and listed for NM (ROMEX) have a large hole all the way through.

Also it appears in the video that to accommodate a short power cable you turned the box so exhaust was pointing away from roof exit point creating a tight bend in the hose. You might consider using a Jbox to splice a longer piece of 12-2 so you could point the exhaust port in the best direction to not have a kink in the hose that will restrict airflow.
Again great instructional videos

super quiet fan means all your bathroom noises are clearly audible. I put in noisy bathroom fans so no one has to hear anyone else's grunts and farting noises. Think long and hard before you install a quiet fan!

[TrustyDreams]

you connected 12/2 wire into the new fans jbox and the wire from old fan was 14/2?

[Forged_Garage]

Nice bro! I like my vent loud it covers up the sound when I’m dropping down the business haha

[timeatak]

Great video. A little tip, use wide masking tape while marking the lines and a shop vac for the dry wall cutting.

[samj]

Excellent video. 2 comments, u didn't mention about the noise rating sones? You also overtightened the cable neck which may cause a short circuit. Thanks for sharing 👍

[NateBraska]

What are your options for the vent if the bathroom is on the first floor? Not sure we have a duct in there currently

[davek]

The reason the vent/ j box assembly comes off is so you can install it from inside the home first, then you slide the box onto it as it goes through the ceiling. If the wiring and vent hose are long enough, there is no reason to enter the attic.

[charlespratt]

If you vacuum out the fan every six months or so they run forever. If you cleaned the old motor out and put a few drops of oil in the bearings/bushings it would probably still be fine. Easy to take the motor apart.
