ERV for Bath Exhaust & in Cold Climates: FAIL or WIN from the Ventilation Manufacturers

Corbett Lunsford

Hear it from the people who manufacture fresh air systems, not just from me. ERVs are for very airtight homes (under 2ach50) to balance the exhaust air from pollution sources inside.

Bath Fan and Duct Inspection Tips for Restoration After a House Fire

Our friend Shawn had a fire disaster last year, and though it’s a terrible loss he’s helping us and our audience learn from the experience. Here’s a quick preview of what will be coming in Season 3 of Home Diagnosis. Here we point out two things to watch out for- one good, one bad.

Attached Garage: Disaster Waiting to Happen?

Corbett Lunsford

FROM 'HOME DIAGNOSIS' Season 2 Ep6: People generally don't think about the performance of their garage, even when it's directly connected to living space with a door or a duct (or nothing at all like this https://www.youtube.com/watch?v=yI2--RdSq-k).

But we keep all kinds of toxic stuff in garages, and they're always at the bottom of the living space, so houses, townhomes, and multifamily buildings may suck air partly, or entirely, from the garage in cold weather. Here's a quick explanation of the what/why/where of garage air leakage that could pose a threat to the health of your family.

How Our Family of 5 is Making Season 3 of 'Home Diagnosis' TV

Corbett Lunsford

We need your help- with feedback, support, and video content from home disasters! For those who'd like to chip in as little as $5/month, here's where you can join our team: https://Patreon.com/HomeDiagnosisTV

Watch the upcoming season and meet the sponsors who are stepping up to help keep this first-ever series about the science of homes going: https://HomeDiagnosis.tv/season-3

We are deep into filming Season 3 of Home Diagnosis, and we wanted to let you know where we're at- we've got a bunch of videos in the pipeline. You might not know, but Corbett edits them himself and so we've got a list of more than a dozen that we're gonna have coming your way.

But we wanted to say a special shout out to our Patreon supporters for being involved, and helping us have a team while we're like so deep into the edit.

The truth is making a TV show is not easy. Especially because funding isn't easy.

And even though we have some companies that really love us, just this coming year there's not funding in their budget for the TV show. So the Patreon members are a huge help, both mentally and financially. And we hang out with them every two weeks, so if you want to get more behind the scenes info on what we just did going through the South Central US, and what we're about to do that Grace is putting the finishing touches on in the Pacific Northwest with our family (we're taking all three of our kids), or going to New York, Toronto, the Carolinas, Miami, Nebraska (the middle of Nebraska- wait till you see what's out there, it's crazy)… anyhow there's a lot that's coming up, and there's a lot of costs that are coming up. So again, thank you so much for being on board with us.

Enjoy these little behind-the-scenes from our Texas trip, and if you want in more deeply, please join us at patreon.com/homediagnosistv.

Season 3 is called ‘Accidents Happen’ and we're going to go back and forth between natural disasters and man-made building science disasters- and sometimes even critters.

Last thing: we have put this call out to our Patreon members, as far as individual homes and the stories that get woven into Season 3, but if you are a home performance professional- and that includes pest control by the way- we're looking for more video content that nobody has ever seen before.

So if you have videos of crazy crawl spaces or attics, or animal problems, or mold, or fill in the blank, please do get in touch with us, and we will credit you and include the footage on Home Diagnosis Season 3 if it can be woven into the story.

So thanks for being on the adventure in general with us on this channel and at HomeDiagnosis.tv- make sure that you comment, if you have things to add or questions to ask, like and subscribe, and tune in next time.

How Perfect Can a New Home's Chemistry Get? Healthy Indoors Minute

Corbett Lunsford

Even with their newly-finished home still obviously off-gassing, and with a massive amount of wood finishes and structural materials certainly emitting formaldehyde, this high performance forever home is testing like a decades-old, well-established house as told by chemist Alice Delia of Prism Analytical. Through the selection of low-emitting materials where possible AND 24/7 ventilation of the spaces, the Lunsfords have achieved their goal of a sanctuary with limited chemistry.

Central Vacuum System with HEPA Filter: Performance Testing for a Healthy Home

For our forever home, we chose the NuTone PurePower 650 central vacuum, which I piped, wired, and installed myself (not very difficult, though parts are hard to get ahold of in a hurry, if you run out).
