Finally a realistic home reno video. As soon as you went in the attic and the vent pipe wasn't connected I was like, "YES!" I don't know how many times I've run into garbage installs. I often stare in amazement wondering how the install could not have failed and surprised half the house isn't flooded or laced with mold.

[@KevJA]

I always found it funny how there are exhaust fans that are bragging about being quieter. I always appreciated louder fans so you could do you #2 business without worrying about someone outside the bathroom hearing the sound effects.

[@NBSWELDING]

Kevin J. A. That is exactly what I think of every time a new quiet vent fan is mentioned...to have the fan make its noise is half the job I expect it to do when I turn it on....and the noise is just as important as the air movement.

[@lrhacker]

First-time homebuyer here. I found your videos when we first started looking for a home to buy almost 7 months ago and didn't know exactly how much work the house we wound up in would need. We finally found a place and will be moving in soon, and this project is one of the first ones we plan to try and take care of ourselves (including replacing non-insulated ducting going out of the roof!). We have a pretty cramped attic space, as well, and since I'm the "small one" at 5'2" I'll most likely be doing a lot of the work up there. All of the information in this video has me feeling a lot more confident to tackle that! :) One of the other projects we have planned for this year is to improve the insulation in the attic. We're in Michigan, so there are plenty of pretty hot and cold days to go around! Currently, there is existing blown-in insulation, but it's uneven, missing in spots, and there is not a large volume of it overall. An inspection found that it likely below an R40 value. Do you have any recommendations on how to best improve the overall "insulation situation" up there? Would just adding additional blown-in insulation be enough? Thanks again for all of your helpful videos. I really appreciate you taking the time to walk through every step, even the "simple" things!

Absolutely one of the greatest How to video guys around. Clear, shows steps and like me discovers problems that happen in homes that are not only 5 years old. We have a house built in 1940 that was flipped. (Kinda). So surprises abound. And thank you for showing the "manhole" crawl space that so many old homes have. This attic looks just like mine! So appreciate the indepth details, and easy explanation. Well done!

[@demef758]

11:50 The problem I have had with my NuTone fans, and I see it at 11:50 with your fan, is the housing which has numerous metal holes stamped in it. Additionally, the open areas around the frame where it cuts into the ceiling is also quite porous. They represent giant air leaks into the attic. I covered all the holes with either tape or latex sealant, and then from the attic I sprinkled loose insulation around the entire housing. After this additional work, my 3 fans are now air tight.

[@johnantinora6222]

Thanks Jeff! I replaced our noisey 10 year old bath fan with a NuTone no attic access model. Your easy to follow suggestions made the install smooth. My older model was larger so I then had to follow your California ceiling patch video! Thanks again. You saved me $500.

[@nsant]

Pro tip: when you move the attic access lid out of the way, use the back of your hands and you won't leave dirty fingerprints. (Same concept with drop ceiling tiles)

Thank you for using a configuration that needed the attic addressed. Too often we get the "everything is right where it should be" video, only to discover WTH on the other side of the "simple" repair/replace video. At the least, it informs us to check the other side, before starting.

[@linusdl]

Thanks for an excellent description in this how to and the very good warning about the attachment of the grill to the ceiling. I would add that instead of using the little M shape wire mechanism, I made two little holes in the plastic and attached with 2 little screws, it took a couple of minutes and easy to do now and later, no fuss. Thanks !

Saw this and as an electrician who has installed hundreds....thousands???? of fans over the last 3 decades I was curious. Awesome job Jeff and thanks for stressing the use of the box connectors and pre-twisting your conductors before putting the marrette on.

Kudos to you for getting in an attic with a camera. Whenever I'm up there, my objective is to get the hell out as quick as possible. I HATE attic work.

[@judycee9263]

Enjoyed your video - went to Home Depot and got the 'no attic access' unit 100 CFM for $119. The instructions provided never referred to the installation of the L-shaped piece with the electric knock-out (it looked different than the one that you installed) in it. It was 81 today and I ended up having to go into the attic too in order to find the 3-wire that my electrician fished up from an old single switch so that I could run the fan and light independently. Thanks for giving me (50+ woman) the confidence to tackle this!

[@northelywind]

I used the version of these fans with lights in both of the bathrooms in my mobile home which has vaulted ceilings througout, so there is no access to void above the ceiling. The master bath didn't have an exhaust fan as that bathroom had a window and code says an opening window negates the need for a fan for some reason. In that bathroom I was able fish wire from the GFCI to a new switch and into the ceiling, then cut the hole in the ceiling, cut a hole in the gable end about 2 feet away and run flex duct over and connect it all without opening up the ceiling more than needed for the fan. The other replaced a noisy 1980s mobile home fan/light and I was able to connect up to the existing roof vent. These are great products for this purpose and saved me from having to put in much noisier and ugly "mobile home" quality fans. Love the videos!

[@jessehickman668]

There’s NO reason water should be getting into the duct. There should be a sealed roof jack and a vented cap on the roof preventing water from entering inside or outside of vent. Ducting is not a P-trap and shouldn’t be installed that way. Any unnecessary bends in the ducting makes it harder for air to flow and the positive pressure in the pipe will make the fan noise louder as well as reduce CFM’s. A toto small diameter duct will do the same. Also excessive bends in flexible duct create pockets for lint to collect and will eventually block air flow. Don’t even bother with 3” duct, Always run 4” for 70-150CFM or 6” for 150+CFM. Always run as much rigid duct as possible and keep entire duct as short as possible to reduce inside pipe pressure. Good rule of thumb match CFM’s to sq ft of room. A 50sq ft or 5x10 1/2 bath gets a 50CFM A 10x10 full bath gets 100cFM, and I always round up and over size them but get 1/2-1 some devices. Panasonic whisper is the bees knees. I’ve installed well over 100 fart fans.

[@donniebrown2896]

Two words "handymen" don't understand, static pressure. I worked in commercial and industrial HVAC and we always did a hard run on fart fans.

[@jasonconnor8492]

Glad to see an early comment about as much rigid duct as possible to reduce static pressure yielding more air flow when compared to a flexible duct of same length.

[@Mote78]

This is why I do my own work. Ripped out the 4 inch flexible lines. Upgraded vents to 6” rigid, insulated R8, 2 backdraft dampers (one on each end) per line, strapped and secured vents, caulked and sealed around fan, installed timer on switches. Immensely superior to the cheap builder install. As the homeowner, I want to prevent problems, save energy and improve comfort for the family. Plus, working with my hands gives me a satisfaction that I don’t get with my office job.

[@Sal-tw8tz]

I agree. Run rigid duct whenever possible. Less chance for moisture buildup. Don't understand why he would suggest his way. Just saying.

[@TrinitronX]

Agreed! That "P trap" style duct bend idea is pretty misguided. The bends will cause extra resistance to the flow, and the resulting air velocity changes will cause turbulence inside the duct. Especially with a flexible duct, all those ridges and sags will cause turbulent flow and unnecessary resistance and energy loss. In the end, this adds up to lower fan efficiency and potential for condensation & water collection points. Both of these are undesirable.

[@MWood-ry8uu]

Personally I think a more preventative exterior vent cover would be the best option. Later down the road when that duct fails from age or rodent damage, you can have a constant leak into the attic where it may go undetected. Not everyone uses their exhaust vent regularly, especially the elderly.

[@davidlindgren7605]

I agree that a 1 sone level fan is just fine. It's not annoyingly loud, but also not so quiet that people might think it's not working. A bathroom fan is one example where having at least a little sound is probably a good idea.

[@brendaconnell4885]

I enjoy your sense of humor over something so frustrating!! I'm replacing my kids bathroom Broan-Nutone fan/light with mine as theirs stopped working. The problem is there is no ducting hose, actually a broken piece @6 in. long and I have reach in and felt around to wall and couldn't find the rest of it or where it goes. Just tons of lint/dust...in joist. In the masterbath, from which I'm replacing their fan/light with, the hose is attached up until the wall then seams to be heading downward but not sure to where?? I've checked soffits outside and there isn't any lint or vent outlet, just sewerage vent tube in roof. These are not attatched to that. I think they're just vented to the wall. I"m going to go thru a very narrow crawl space in my attic that I finished and already took extra insulation I put in at the time and hopefully see if the hose/hoses are attached to anything before I put in my fan. We bought the house new 23 years ago in a few days and replaced these already. I appreciate any light you can shine on this very frustrating situation that I'm not taking any near as well as you!!! Thank You in advance!!

[@HomeRenoVisionDIY]

Cheers happy to help and Congratulations!

[@Stevelemontrudy]

Another option can be to buy the same model fan as the existing one, and just swap the motors out. Easier said than done but not a terrible job. You may need a multi tool with a carbide blade to cut the old motor and mount off the new and old units. You may need metal drill bits to drill out rivets to remove the motor/ mount. You will need self tapping metal screws to install the new motor and mount into the old housing. Not too tough and it's way easier than trying to remove an existing unit. Edit: It's also an excellent option if you don't have a space to access the old fan's attachment points.

[@misspinkydiva]

I thought you were gonna use the rotozip to cut that drywall lol. I was waiting on it..lol i like the rotozip

[@SaltySugar]

need an exhaust fan just to use the rotozip. so much dust!

[@jeffmiller7942]

I just installed a similar fan this week, but didn't know the option to install without cutting sizable drywall from around it. I don't recall that being in the instructions. But I also had to move the fan because the electrical was too short for the way the exhaust was oriented, so I would have had to open up the ceiling regardless. The homeowner chose the fan, but I probably would have bought the same one for the space and budget. It's good to know there's a product out there that can be installed without accessing the space above or slicing out several inches -- or feet -- of drywall. Thanks for the great tutorial.

[@billybudd9236]

Jeff, Thanks so much. Inspired me to install the Nutone fan you recommended.

[@koryleach9660]

As a guy who does air sealing and insulation for my business I appreciated your pain in the attic. I have one additional step that I recommend with bath fans. In the attic side use a fire blocking foam I.e. Great Stuff around the base and caulk it from below to prevent the conditioned space air from having an easy route to get into the attic’s cold space.

[@ericmuller3339]

Will the condition space air going to the cold attic air produce ice on the nails in attic during winter season?

[@HomeRenoVisionDIY]

yes it will, and mold on the plywood!

[@koryleach9660]

Eric Muller Yes, that is why the sealing of bypasses is so important. If cold enough for any length of time it can go so far as to make icicles that when melting will discolor the ceiling and as mentioned can allow mold to grow. I’m going to make $11K in three days later this month because of that very issue.

@@HomeRenoVisionDIY yah but what if there's 6 wires and they're red black and white... Lol

[@RobertSmith-ge8hj]

The red and black are separate power switch legs for combo fan-lights. One is for the light the other is for the fan. Usually your fan will have a separate blue wire that controls the light and that is what you connect the red wire to. But if you dont know what your doing call a professional

[@mitv123456]

I agree. My wires from old fan are too short. How do I add to wires to get additional length?

[@sqqqrly7750]

If your fan is fine except the motor is dying (noisy), you may be able to buy a replacement fan motor for $25. This is much easier to install. Mine seems to die every 8 years or so. The fan he is showing looks pretty nice.

Cheers erica!

[@ratdog3055]

My old fan was simply vented to the attic! Do you have a video showing how to install a roof vent? I understand that running it out to the soffit is a no-no.

[@marc.lepage]

Into the attic is super bad (mold!), into the soffit is not good because it's not made to be a vent (backpressure among other problems). There may be a soffit vent you can install, but generally speaking, roof vents will come with their own installation instructions, the key is to follow them properly and ensure the vent is installed into the existing roof system (membrane, shingles, etc.) properly. Maybe there are retrofit vent installs though?

Cheers my man! Can do both at the same time once in a while.

[@sandyb2391]

i absolutely love watching your videos. you explain everything exactly for us do it yourselves people. thanks again for letting me know how to do this. my bathroom fan had no venting at all through it. now that is crazy. found that out after going in the attic now had that put through the roof. crazy how some of these homes have been done

[@HomeRenoVisionDIY]

There are a lot of contractors who cut corners in the attic. Cheers!

[@sandyb2391]

@@HomeRenoVisionDIY thanks, that is for sure. i thought that was so crazy not to have the venting at all. so when i have the fan on it has been blowing straight into the attic. i was not impressed the least. so wish you lived in the fraser valley. not far from vancouver. lol

[@Jamthrutraffic]

Beautiful. I love your no-nonsense directions. I have a metal roof and don't fancy cutting through it but I have a home with NO exhaust fans in either bathroom. Can these be installed through an outside wall up high close to the eaves?

[@brendahaynes6922]

Great video!! How would you rewire a bathroom fan that has separate switches for light and fan on to one switch only?

[@rlw3461]

You always get me laughing, your so down to earth I love it!

[@gilbertomartinez6981]

Its good you explained about the CFM and advantage of straight up the roof exhaust vs the flexible curved ducting. Very nice explanation. What do suppose is going on if my one bathroom power line ground wire to the fan reads 0.4 volts AC? Meter also reads that same voltage when checking the metal housing even though the wall fan switch is off. I only found out this bare ground wire was live because i felt a little shock when removing the fan to clean it. Thanks for posting this kind of video i have a second bathroom that does not have a fan and plan to follow your guide

Unfortunately, that is the name of the game with home renos. You're usually doing the job because the last 'pro' screwed it up.

[@bondpit8750]

Dave C. Right on, more typical than not.

[@spongebobsps123]

Good video, thought I was going to have to go this route when I discovered the fan in the guest bath (which hadn't been used since buying the house in December) wasn't drawing air. Found out that when they sprayed the texture during the build (1999), they sprayed the fan flapper. That would explain why the fan looked almost new, nothing was vented outside -- simply recirculated within the bathroom. I'm actually shocked that there are no mold issues as this is NW Florida. Cleaned up the flapper, sealed the box and it draws just fine now.

[@spongebobsps123]

One thing I failed to mention was depending on the region and the year the house was built, a bath fan may not have been installed (and not really needed). We lived in Utah and neither the upstairs or basement baths had fans; with the low humidity there, the showers would dry in no time flat even w/o air movement. Getting farts out? Well, that's an entirely different story. ;)

[@38tech]

Jeez, how easy is that. Lol literally any and all questions were answered. Keep up the great vids!

[@ceasaraugustus1758]

My fan was installed without any duct work, it was covered with blown in insulation.

[@9873459872134234]

FYI that can start a fire. Motor can overheat bc of excessive resistance.

[@EDBailley]

Wow those people need some serious help omg, craziness! Smh well at least they made one smart move, calling you to do their repairs.

[@HomeRenoVisionDIY]

we did the entire bathroom. What a nightmare reno before that. The entire video on that bathroom comes out this Saturday. Cheers!

[@EDBailley]

Oh wow I know it looks a thousand percent better now. I will be looking forward to the video! Cheers!

[@shagornodi3569]

Helpful video thank you, just a question if you want to clean the fan or housing how do you slide it out?

[@hurph]

I installed one last year and had no idea I could remove the inside. Had to make a bigger hole in the ceiling cause I had no idea you could remove those side flaps! Thanks... now I'll be ready to replace it.

[@HomeRenoVisionDIY]

That is why i am a big supporter of reading the instructions. Cheers!

In the future I would wear a mask in the attic. You don't realize how much insulation you just breathed in. Take a picture with flash on your phone if you don't believe me, micro particles are entering your lungs as you made this video.

[@DarshilPatel95]

Clairity o agree with you. Even tho there is shortage of mask right now, I made some homemade mask to stop what I can

I really love watching your videos and appreciate the wealth of USEFUL information that you put out. Curious- will adding too many bends in the duct reduce cfm much or is it not that critical?

[@HomeRenoVisionDIY]

no more than 3 and you will be fine and no longer than 15' if you have 3 bends. Cheers!
