We're back again with my HVAC design calculations trainer Alex Meaney (https://MeanHVAC.com), to talk about ductwork and connections and filters and how to get all this right when replacing an old system in existing homes.
Watch my first two videos with Alex: Manual J Load Calculation https://www.youtube.com/watch?v=LEKEMI05dJE

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'.

Using a Testo hotwire anemometer and hygrometer, Retrotec FlowBox, and CPS EasyHood, we commission this Fantech SER150 energy recovery ventilator and tune it to our high performance home's (and our family's) needs.

Modern homes need dehumidifiers, separate from the air conditioner. We chose the highest performance units available, Ultra-Aire's 120H and MD33- here we'll give you a full tour of the planning, sizing, installation, and testing of these machines in our performance-tuned, self-built home.
See these two dehumidifiers we selected for our home:

Another installment in a series with Healthy Indoors Magazine (http://HealthyIndoors.com) follows the real-life, gritty planning and installation of the make up air system in a 1950's ranch over a crawlspace. The goal here is to install effective ventilation for the kitchen range with an exhaust hood AND make up air that will hopefully be the path of least resistance. We're using a Broan exhaust hood paired with an Aprilaire KV make up air damper, or an 8144NC (in an experimental application, as explained in the video). This house is not airtight by any means, and some might think make up air is overkill in an older home, but obviously we disagree enough to suffer through this.

Welcome to the training center of our dreams! In this multi-use space at our newly-constructed high performance home in Atlanta’s College Park neighborhood, we’re hosting professional and DIY crowds who want to get hands on with the science of homes: design, installation, and testing.
Come learn about diagnostics, ventilation, air tightness, HVAC, ductwork, blower door testing, infrared thermal photography, moisture investigation, and much more in this state-of-the-art contaminant controlled room. Our balanced Energy Recovery Ventilation system, HEPA filtration loop, and dedicated dehumidifier all work with stellar airtightness and insulation to create a clean, quiet classroom only 5 minutes from the busiest airport in the world.

In our LONGEST VIDEO YET, get a comprehensive tour of the concepts, design, tools, and install tips that go into building a home's breathing apparatus- the central duct system. Here I get into both the conditioning duct system (heat pump/dehumidifier/filtration loop) and the ERV fresh air ventilation duct system.
Thanks to Neil Comparetto (https://www.facebook.com/comparettocomfortsolutions/) John Semmelhack (http://think-little.com) and Bryan Orr (https://hvacrschool.com) and many other HVAC pro friends for their continual advice and expertise.

Here are my favorite bits of gear for building a high performance home, including my entire brand new Malco sheet metal ductwork toolkit.
For our family's performance-tuned home, I’m giving you a deep-dive into the beginning stage of the heating/cooling and ventilation ducting throughout the house. See assembly, fastening, sealing with mastic (the good stuff, not the cheap stuff) for duct boot stacks and outdoor vent hood terminations.

Watch home performance testing guru Corbett Lunsford test the pressure, airflow, and velocity performance of some beautiful custom carved wooden return grilles, using just a blower door kit, a homemade box, and an anemometer. Grilles made by Stellar Engraving by Vencor Inc. (http://vencorinc.com). Test performed out of the back of Corbett's pickup truck in Atlanta GA! Yeehaw!
Home performance diagnostics guru Corbett Lunsford demonstrates the simple test for kitchen exhausts of all types with a smoke pen. See how downdraft exhaust fans work (or don't work) and make a more informed decision on what to do in your own kitchen!
Watch building forensics expert Corbett Lunsford demonstrate Total External Static Pressure testing and pressure drop testing for a residential furnace and air conditioner.
