If you let the fan run for 5 min and then get your IR camera out you would see where all the cold air is coming in. If pressurized the house the smoke puffer would show exactly where the air is leaking out to as well. That would be a neat trick!

I'd also recommend looking at any bath fans, range hoods, and other large wall/ceiling penetrations. The openings may be significantly overcut or the baffles may not be doing their job due to poor installation, wasp nests, etc.

That effective leakage area of 126 inches squared in the first test. Basically like having a large window open full time. Even the second test at 87 inches squared is a window open. Most people never realize how much air the leak on a house. Glad to see you pointing this out for people especially if they have allergies or high energy bills.

Well, sort of but in practice you open and close doors enough to get fresh air, and it's always better to intentionally add fresh air that you can filter and turn off on those hottest days to help cool the building.

at 32:54 It looks like the can lights you have (NHRIC-17QAT) are ICAT, meaning that they are suitable for insulation contact and are airtight (per astm e283). That's probably why you didn't see much of an improvement with the can light covers.

When you remove the attic insulation, 1) use fire-block foam (orange stuff) and 2) literally foam bead every single crack and joint of all the materials. From the perimeter to every butt joint corner of drywall, drywall to wood, hole into wood ( electrical doing into your walls), vent pipes... literally everything. That (especially for cinderblock homes) is enough to eliminate 60-70% of your joint/lighswitch and receptacle infiltrations.

Ive been running residential blower door and duct leakage tests in north carolina as my full time job for the last 3 years. I feel like were in the same boat, my house was built in the 80s and I know there are ways to improve my efficiency. I just need to find the time to address them. I think you did a great job learning how the equipment works and systematically tracking your progress. Starting with the bigger leaks and then looking for the less obvious. One area I might suggest taking a closer look at is where your plumbing penetrations come through from the crawl space. I often find toe kicks on cabinets and vanitys leaking from plumbing that wasn't foam sealed. Fantastic work man!

As I think someone else in the comments mentioned, basic expanding foams like that are open cell and not as air tight as you'd expect, and even closed cell foams aren't always very effective when thin. Construction adhesive or even plain old dirt cheap acrylic caulk should be very effective, though. Ideally use an intumescent type (firestop) if you're going to the effort of sealing cable penetrations. Probably worth hunting the low hanging fruit like window and door seals before obsessing over that sort of detail though.

if their not IC rated(insulation contact) and all accessible from attic, you may be better off changing them out to sealed IC rated units and seal their flange gasket to the ceiling. it's not a fun job at all. "they'll be listed as "air tight" or similar. generally meant for new construction work, so you'd need full access from the attic side. they may have some remodeler cans that are air tight. that I'm not sure.

I have 4 cats, and one resembles yours. I've never had a dog that plays fetch, but I have two cats that do. It's really funny because I adopted a brother and sister, and the boy played fetch for 5 months, then one day the sister thought, if my brother can play fetch, I should be able to bas well. She's not as dedicated to it, but still fun. To see if your cat will fetch, ball up a piece of paper, like a cash register tape, and then throw it. If your cat brings it back, you'll know.

I did home sealing for a little and you wanna seal the top plates on both sides throughout the whole home. as for the rockwool covers..... not sure how well they seal airflow but the foam look applied correctly. we used to build custom covers out of foam board with silver backing. of course also make sure to seal the top plates where the wire goes through the wood. what i would also do is tape the boarders of your windows just so you have a baseline leakage number you could look back on to see what's really doable

Are you going for heat recovery with your heatpump to get fresh air into the house? remember Oxygen is not the problem in a sealed House, it is the Carbondioxide, which makes you feel sleepy. Outside air got like ~400 ppm, at 2000 ppm it is not so good anymore. CA should be pretty close to EU max values of CO2 for indoor.

Hi Chris, I get that you might have expected a bigger number from the covers on the lights, but don’t forget that they will help insulate the lights so that there is less heat transfer through the lights. I don’t think that you wasted your time or money. Looking forward to seeing your ongoing finding with your project.

This gives me a good idea of where to find/improve the leaks at my place. Thanks. Didn't expect light switches to leak that much, and I know I have leaks at both the tops and bottoms of the walls. No ceiling space to work in here, most of the house it's less than a foot between ceiling and roof, but a fair crawlspace under the house, can just about stand up in some of it, but other places I have to slide through to get to different sections. All split system heat pumps, 5 of them, only 2 working after floods in Feb but they're keeping up with the load.

This was an informative vid.! Thanks. Glad you are using LED recessed lights, less heat. I recall a house we had with reflective silver coated cardboard around the sides of the recessed lighting fixtures. (Was utilized to keep the blown in fiber insulation, away from the hot fixtures, (pre LED days). These rings were right in the crawl space path, easily getting tipped, allowing the insulation to get trapped right next to the hot fixture. (Everything built the cheapest way). Found the conditioned air ducting to the lower level of the house, knocked / blown off. (That low tonnage air unit needed to work extra time, in-order to keep both the house and attic conditioned). (Called the original installation company to correct it. They did, using a bunch of duct tape. 🙃😳

Those Can light covers look like they're more for fire protection and heat/cool loss not necessarily airtight. Because Can lights tend to end up getting cut into Attic spaces that aren't insulated or spaces that are too tight for insulation.

For the how much attic air question, could you use the temperature difference? Probably not the best time of year due to the relatively low delta between return air and attic air temperature. However, if the return air is 70, the attic air is 50, and the mixed air is 60, then it would be a 50/50 mix, if the mixed air is 65, then it would be 75% return air and 25% attic air.

Still you have the windows and seals around the doors as a air leak not counting the wall to floor joints. The can lights your house has lose air via the metal tube that connects the joint box to the can light if possible replace the can lights with surface mount led lights they have a smaller connection box and spray foam insulation in the attic with the fiberglass insulation would help seal the air leaks and keep you cool at a lower electrical cost.

Regarding your disappointment regarding the effectiveness of the can covers, I suspect that the smaller decrease you observed may be due to the law of diminishing returns. The fact that just taping up the drywall holes etc, resulted in a ~25% in leakage, means that each of the other measures you took had less of an effect than if you had made them in isolation. Had you covered the pot lights first, and then taken a measurement, you would have likely seen a greater decrease in leakage.

I love how the blower door tests were simple to use and easy to understand with the app. I did not understand a thing when I watched Bill's videos on his house. Also I'm no expert so I'm not saying what the right way to do the pot light covers is but I think I would have used silicone to glue them down and probably removed the bracket for the electrical box and just had a single hole that is easy to seal for the wire to go into the light. I feel bad that you lost a bunch of money on something that didn't really work.

After sealing and caulking, etc., I arranged blower door tests for a couple of clients, all with somewhat larger houses than yours in the pacific northwest . The big air leak surprises were in order of severity: pocket doors; around duct boots and bath fan housings; plumbing penetrations under sinks. Something I've found that is not well covered is heat gain/loss via infrared radiation - check out Low-E window glass and Low-E coatings. Another common sense move is repositioning the condensing unit out of direct sunlight. I couple of books you will find more than helpful in your efforts are: Residential Energy: Cost Savings and Comfort for Existing Buildings by John T Krigger et al., and Insulate and Weatherize: For Energy Efficiency at Home (Taunton's Build Like a Pro) by Bruce Harley . The first one is expensive at about $90.

I was thinking put a low grade build grades caulk around the ring , and maybe put painters tape on the dry wall with the painters tape you should be able to remove the light in the future for future service so it doesn't pull off the dry wall as you do it.

Sorta tangential, but there are emerging devices for dealing with aerosolized pathogens using far uv. I think the term is upper room UVGI. Previously that was mercury lamp based, but the new stuff is LED based an pretty compact. The Hong Kong government released new air quality regulations in English specifying UVGI fixtures paired with far higher air change requirements. I think Philips makes uv-c fixtures for that purpose. You might have decent positions in the vaulted ceiling area to mount a UVGI fixture.

Super late but are you putting in an outside air heat exchanger?? (I think that's what that's called) for swapping out fresh

I know I am late on this, but did you tape the doggy door? I'm imagining it could be pulled up by the pressure difference, but you probably saw it while running around with the smoke.

I can see the differences in heating and cooling first hand between a house built in the late 90's (my Parent's place which was built in 1998) and a house built in the late 60's early 70's (My place which my grandfather built from recovered material in what we call now as Upcycling). First of all there is only 2 years between the install dates of the furnaces (we have slowly over years been fixing the duct work as there is not enough cold air returns and the main plenum was never sized correctly until a few years ago) and the exact same air conditioners installed only a year apart. My Gas bill which provides the main heat for the 2 houses is cost wise more expensive than my parent's place but on the other hand because of my allergies I tend to do better with with windows open or at home compared to a sealed tight home or at a workplace that also has A low humidity. When it comes to weather conditions I prefer Cuba weather in November as that is when my allergies are at their lowest.

Your hardwood floors are really beautiful. The cost of that floor today would be outrageous expensive. Why would you want to get rid of it? It can be sanded and refinished if there are any bad spots without wearing down any laminate finish. That is solid wood all the way through.

"Only meant for residential". I've lost count of the number of times great new better/cheaper/faster has started out small and then grew up and ate the lunch of the "big boys". The personal computer is a great example. Mainframes were common in companies, now they're rare.

Something to be aware of when sealing up you're home! Carbon monoxide detector! I knew a family in upstate New York who were in a very drafty house. During the winter I believe it was a gas furnace that malfunctioned!... during the night!... The only reason that they were alive from what we believe was that thank God their house was so drafty!

You would not believe how much air leak via windows or doors to outside (it is much better with newer ones) Also shading south windows with outside (slightly smart )jalousie may help to prevent sunshine ro heati inside of house but how much that is unknown and probably worth only for passive house

edit: NVM you talk about it later. For the can lights you should see how well those led bulb replacements seal as they have a foam gadget that supposedly seals it vs the covers you talked about. But theirs not much presher on t so I dont think it does too good of a job

I wondered about those. If there's room you could caulk it to the ceiling (carefully so it doesn't look bad). But it's gotta be better than no seal at all.
