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

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.

Basement in Florida? Why Mold Took 20 Years to Fail this House...

A very cool client of ours named Niko came to us with a wildly different home issue- a finished basement. In Florida. That's vented to the outdoors. Watch us tour the home being renovated with Tony Gomes, my Tampa go-to-guy for advanced diagnostics on existing homes. We explore how it's possible that mold was held at bay for 20 years, until Niko did a 'good' thing and replaced an old HVAC system with a VRF (variable capacity) heat pump.

ERV Setup Testing/Commissioning, Using Pressure Curves to Measure Airflow

Using a Renewaire SL70 energy recovery ventilator and a TEC DG-8 pressure gauge, Corbett demonstrates how to set the low and high speeds on an airtight home's balanced ventilation system.

Automatic Ventilation Control with Broan-Nutone's Overture: Customizable, Modular Fresh Air System

Places are different, homes are different, families are different. There IS NO SINGLE SOLUTION for ventilation, and that's the way it's likely to stay- so the more modular, customizable components we have access to, the better.

In addition to having some of the most advanced ERVs in the world (stay tuned for more on that), Broan has now made customized, modular ventilation systems much more practical with this lineup of Overture controls: room sensor, wall control, and smart plug- all linked to the algorithms in an app.

The Overture system can control exhaust fans, supply fans, make up air dampers, and ERVs/HRVs- we hope they will continue to push forward into controlling air handlers, dehumidifiers, humidifiers, and more. Learn more about this system and start brainstorming what you might do with it at: https://Overture.Broan-Nutone.com

Filterless Air Cleaners Make No Sense: Airfree Lotus Air Purifier

Honestly, it's starting to piss us off that some of these marketing teams are combining their shocking lack of understanding of what they're selling, with an assumption that their customers won't be able to understand it either. Let's fix that right now, starting with this Airfree Lotus 'filterless air purifier'. Oh, and they make one specifically for baby rooms too, if this wasn't dumb enough already.

If you need cleaner air, use good filters, or dilute with outdoor air using something as simple and affordable as an AirCycler: https://www.aircycler.com/

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.
