How to Test HVAC Room Pressurization (Zonal Pressure Testing for HVAC Commissioning)

Corbett Lunsford

Using a TEC DG-8 manometer and a Testo 400 hot wire anemometer, Corbett evaluates the HVAC balancing in the home his family built in Atlanta. Keep your room pressures below 3 Pascals if you can, 5 Pascals will start to give you problems- rooms don't receive enough conditioned air, and/or whistling or doors closing from 'ghosts'.

Central Vacuum System with HEPA Filter: Performance Testing for a Healthy Home

Corbett Lunsford

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/

Uncomfortable Homes Explained: How Air Sealing, Insulation, HVAC and Thermal Mass Actually Works

Corbett Lunsford

From the upcoming Season Two of 'Home Diagnosis': through a 5-day recording of temperature, humidity, and dewpoint with a datalogger, see the actual performance curves of five built environments on our property. Watch the evolution of primitive to advanced built environments, from an open-air workshop to a lived-in high performance home- the effect of air sealing and insulation alone is pretty incredible when you see it like this.
