Airtight Home Ventilation: Where to Place ERV Exhaust and Supply Grilles

Corbett Lunsford

I only recommend ERVs for very airtight homes (less than 2 ACH50), and in those cases balanced ventilation is the ONLY way to exhaust from bathrooms. More coming on that for those who are scratching their heads. If you DO need an ERV or HRV (hear the difference at https://www.youtube.com/watch?v=QOe4lluGwCg) then where do you put the supply and exhaust ports? How many CFM should they each push and pull? Here's my simple breakdown of what you'll need to consider.

How to Hide HVAC Grilles and Replace Your A/C Faster

Corbett Lunsford

Floor, not so great but probably better than this. Learn more about HVAC performance by subscribing to our channel and joining our Patreon membership: https://Patreon.com/HomeDiagnosisTV

Corbett Lunsford

From 'Home Diagnosis' Season 2 Episode 9- most bathrooms are not designed for performance, let's admit it.

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.
