Whole Home Depressurization: Worst Case 'Thanksgiving Day' Scenario for Pressure Imbalances

From 'Home Diagnosis' Season 2 ep7: It's important to test how much suction your home can create with the machines and duct systems built into it- is it sucking hard enough to create unhealthy contaminant or moisture problems for your family? Here's a quick look at the 'Thanksgiving Day scenario' we worry about in homes new and old. See this entire episode: https://homediagnosis.tv/episode-207-slow-burn

Attached Garage: Disaster Waiting to Happen?

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 Air Pressure Can Screw Up Your Home: the House of Pressure

Take a tour of the dynamics of home pressure with Jake Nuckolls at the Building Performance Center in Bellingham, WA. This training tool has made the invisible visible for thousands of home performance professionals, and we thought everybody else should get to see it in action too!

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).

Check out this system, and other Broan-NuTone machines: https://broan-nutone.com/

Testing a Radon Mitigation System

Corbett teams up with Fantech's aerospace engineer and radon system expert Hamid Massali to prove the radon mitigation field works, and find out how much airflow the radon fan will need to exhaust to maintain safe air quality indoors.

Corbett and Grace are not joking around- they will diagnose the crap out of the forever home they're building. Here's another example of creative testing that can tell us secrets about predicting and preventing failures in the indoor physics, chemistry, and microbiology of homes.

Cleaning House May Be Bad for Your Family

Home Diagnosis co-host Corbett Lunsford explains why the HOMEChem scientists are saying cleaning might not be the answer for indoor chemistry. Explore the meaning of vacuuming with and without a HEPA filter, and where a central vacuum system should be installed to keep from totally messing up your indoor physics and chemistry.
