Best Place to Put a Bath Exhaust Fan

From 'Home Diagnosis' Season 2 Episode 9- most bathrooms are not designed for performance, let's admit it. If your mirror gets fogged up, if it takes 30 minutes to exhaust all the steam, if your ceiling drips or your walls have streaks on them, you can do better. Most of this, insanely, has to do with WHERE the bath exhaust fan is located. Here's your quick crash course to help you school all the builders, remodelers, and mechanical engineers in the world.

HVAC Zoning: Do You Need It, or Not?

We get asked this a lot, so here we're trying to explain as concisely as possible why zoning is often a symptom of a badly built home enclosure (or a poorly planned McMansion, obviously). If heat is bleeding through the skin of a home at a controlled rate in every room, there's no need to zone the HVAC system to give special attention to a weak link. There are no weak links in a well-tuned home enclosure, and so your HVAC system can be simpler with fewer components, and more sure to effectively condition the home.
