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

Testing Water Heater Spillage: Backdrafting Combustion Fumes from Natural Draft DHW

I've tested hundreds of combustion-fueled heating appliances, and this is way more common than you'd hope. Watch my friend Wade Thompson of Utah's amazing Intermountain Weatherization Training Center give a quick demonstration of how easy it is to pass and fail this important home health test.

'Home Diagnosis' Finally Puts Home Performance Testing on Mainstream TV

Grace and I have been trying to make a TV show about home performance testing for years- we've tried three times so far!  This is how it works traditionally:

1. You get a network executive to want to see you as a couple onscreen because they think you're quirky or weird or otherwise compelling in a I-can't-look-away kind of way
2. You work with a production company and pay out of your own pocket to shoot a 'sizzle reel' that shows off the personality of the hosts
3. You remind yourself and everyone else that your show is about SCIENCE, not about relationship drama and being quirky or weird
4. They remind you that no one cares about the topic in reality TV
5. You feel frustrated and you throw the whole idea in the garbage because you don't want to play their stupid game

So we've decided to make the show ourselves, without asking anyone's permission. We find that works best for us- whether self-publishing a book (Home Performance Diagnostics) or making a feature film (The Other One), it always seems to work perfectly when we don't have someone breathing down our neck to conform to 'the way things get done around here normally.' Here's the show that will actually make it onto mainstream television: HOME DIAGNOSIS.

In 2014, we pushed hard for a show called PRESCRIPTION HOME PERFORMANCE to get made, but it went exactly nowhere. We went to the national RealScreen Summit, a non-fiction television programming conference (yeah, I know!), met with all kinds of networks to pitch the idea, and finally had Science Channel interested until they finally said, "wait, we don't want to compete with HGTV." And that was that. But you can still see what the show was like here:

And way back in 2009, we worked with our friends and client Sandy Gordon to make OUR GREEN COMPANY, which resulted in all of us being told by the Discovery Green channel that 'green' was a fad. Look at these kids- so young, so fresh, and maybe clueless!

Stay tuned for developments on HOME DIAGNOSIS- at the very least, it'll show on PBS just like This Old House does, and at most, it'll be running 24 hours a day on every channel there is.  Probably it'll be somewhere in between!

What Spillage Looks Like from a Water Heater

Testing for "spillage" of combustion gases means making sure the bad stuff that's supposed to go UP the chimney doesn't come back DOWN.  It's a critical part of home performance analysis, according to BPI, RESNET, and everyone else.  If you don't know what it looks like, you might feel a little lost- let your old pal Corbett the diagnostics guy show you the single most awesome example of what you shouldn't see in your clients' homes!
