“I grew up thinking that a research scientist was a natural thing to be.” Stephen Hawking There’s physical science. And there’s a kind of science as to how the mind works and how people achieve their dreams. Blend one-part plasma fusion physics with one-part commercial real estate and stir this in an open and creative mind and you have Peter Capuciati, the Chairman and Founder of Bluon and the guest of today’s podcast. Starting in 2011, Peter has led the team at Bluon to develop a true solution for R-22 replacement. It’s called TdX-20 (R-458a), something unlike anything the HVACR world has ever seen. It truly is an energy saving product, as they are demonstrating amp draw decreases of 10-20% and increases in capacity of 3-6%. We love digging into the science of HVAC in this podcast, and Peter is the perfect tour guide for the challenging journey of creating a refrigerant chemistry that has been proven to perform in about 80% of R-22 systems. This is backed up by real-world testing on equipment, not just simulations After an easy, free registration and testing process, techs can gain full access to the operating manuals of over 22,000 types of R-22 units as well as individual retrofit instructions and compatibility ratings for each unit. Beyond all this, Bluon provides the training, know-how and demonstrates (sometimes in person) the skills necessary to successful do a successful conversion. If this sounds like a commercial for Bluon, it sort of is, as we sell Bluon at TruTech Tools. However, this is exactly the kind of product we love selling; smart, well supported and one that relieves a major pain point for our customers. Plus, it’s fun working with the energetic Ninja team at Bluon, or as Peter calls them the Analog Renaissance Cowboys. You can learn more about Bloun at www.BluonEnergy.com and join the thousand technicians every month that are downloading and using the app.

EP45 Making Homes Perform better – HVAC tips with John Semmelhack

“True genius lies not in doing the extraordinary things, but in doing ordinary things extraordinarily well.” General Louis H. Wilson, Jr. Building science principles are few and fairly straightforward; ordinary, perhaps.   HAM: A lot of it amounts to control the flow of Heat, Air and Moisture.   But, like so many things in this world, the devil is in the details. Listen in as I chat with my good friend Nate Adams (a true genius) to get an update on his extraordinarily execution of ordinary measures in his new concept of Home Performance 2.0.   This is a follow up to Episode 36, where I interview two of the HP 2.0 practitioners, Neil Comparetto and Michael Housh.   Measurements (so near and dear to my heart) are at the core of what he and his HP 2.0 army are all about.   For a more complete overview, tune in to a recording of his recent webinar on HP 2.0: www.bit.ly/NATE-HP20   Nate’s book, The Home Comfort Book, is perfect for consumers or practitioners alike and can be found at TruTech Tools or on Amazon.   You can reach Nate at Nate@EnergySmartOhio.com.

  I can’t change the direction of the wind, but I can adjust my sails to always reach my destination. Jimmy Dean While we picked a specific topic, this is a wide-ranging episode with my friend in the industry, Eric Stromquist of Stromquist.com – 2nd generation controls distributor based out of Atlanta, GA. We discuss our thoughts and opinions on: How hard it is to actually get access to people – cold calling is basically dead Closed vs. open architecture in building automation systems C suite execs focus on productivity, which ties in to all building systems How the internet has changed the way information is shared- knowledge hoarding is done The psychological effects of improper lighting And much, much more.   Eric teams up with Ken Smyers to manage a ton of educational and informative resources centered around building controls and automation that you will find at  www.ControlTrends.org They even have their own Awards ceremony that takes place before the AHR Expo!   Eric is an avid podcaster and actually had me on his show in Episode 311!

EP42 Smart buildings and HVAC Controls- News you can use with Eric Stromquist of ControlTalkNow Podcast

To keep the body in good health is a duty…otherwise we shall not be able to keep our mind strong and clear. Buddha HVAC and building performance contractors are seeing more homes built or retrofit to tighter levels. Blower door test outs like 3, 2, 1 ACH50 or less.   What do you do when the “house can’t breathe?”   Hopefully, you see the humor in that statement.   Of course - you build it tight and ventilate it right!    (Credit for that phrase likely goes to Earle Perera and Lynn Parkins as the title for their article in the June 1992 Building Services Journal a UK publication)   Listen in as Ty Newell founder of BuildEquinox shares with us how he got to the point of feeling the need to create his own ventilation product, the CERV2: Conditioning Energy Recovery Ventilator.   This unique product senses when to run, ventilates or recirculates the “fresh air stores” in the space using a small variable output heat pump. It incorporates slick controls and internet connectivity.   Plus, I cannot wait to be using it the new high-performance home we are building for occupancy by the summer of 2020.   Learn more about the product and more importantly the philosophies behind the product by surfing over to www.BuildEquinox.com   The BuildEquinox site has numerous white papers, tech specs & installation info, recording and upcoming webinars and more. You can also learn about the net zero house (which includes the CERV 1) that Ty built.

EP 41 Great Indoor Air Quality Can Improve Your Health with Ty Newell of Build Equinox

In this age of high technology and Jedi Knights, we often overlook the need of personal involvement, but we do so at our own risk. William H. McRaven (American Solider) Attention all HVAC Techs: Soon someone will be looking over your shoulder.   Not it’s not the Homeowner, with severe coffee breath and a million little questions, it’s going to be a Home Energy Rater giving a grade to your HVAC installation.   What???!!!   Yes, like it or not, this will happen.   And it is justified.   It’s because the work done by HVAC Technicians is so important; important to the occupant’s comfort, safety and health as well as their utilities bills AND the utility companies in general as they try to balance the supply and demand of energy.    Residential HVAC energy demand is a big topic in the utility world. (We’ll do a podcast on this later.)   Listen in as Jeremy Begley of HVAC Design Partners of Cincinnati, OH shares with us how paying attention to standards as helped to shape his entrepreneurial career. Specifically, the upcoming ACCA/RESNET standard on Grading the Installation of HVAC Systems.   One timely note here: the comment period on the first draft of a new RESNET standard (BSR/RESNET/ACCA 310-201x, Standard for Grading the Installation of HVAC Systems) closes on Aug 6, 2019. If you want to review and/or comment go to this link ASAP www.bit.ly/RESNET-ACCA-310   Jeremy’s got a lot to share with the both the HVAC and Building Performance industries. He came on the podcast to encourage others to review and engage in this and other important HVAC Standards.   The methodology in the standard has five steps – a design review, a total duct leakage test, a Blower Fan CFM test, a Blower Fan watt draw test, and a non-invasive evaluation of refrigerant charge (NIST found in MeasureQuick). These five tasks should be completed in sequence and upon completion the results are evaluated for compliance with thresholds. The result of this process is anywhere from a failing system to a grade 1, 2, or 3; with 1 being the top grade and all grades yielding extra points in the HERS rating.   Besides being important to HERS ratings, it is basic physics and the methods described have positive impact outside of the rating world.   Learn more about the standard itself by going to http://bit.ly/RESNET-310-INFO, where you will find a link to RESNET conference slides on this topic and a link to the other podcast I host, RESTALK, where I interviewed Wes Davis (ACCA) and Den Gamble (EPA) on this standard.   If you want to learn more about the services and training (coming) that Jeremy offers you can reach out via the contact form on his website: www.HVACDesignPartners.com

EP40 Why You need to Pay Attention to National Standards Affecting HVAC Installations with Jeremy Begley

Looking to be a better HVACR Tech?   One key aspect is keeping up to date with changing equipment, products and techniques. And that is no mean feat.   In order to do so, you need to help yourself to training and education where ever you can get it. Like this podcast… especially because it is on a lesser known topic: HVACR Chemicals and sealants.   Mike Walton of CoolAir Products in Maryland, joins us on this episode to focus on 2 of the products he has brought to the US market: AC SmartSeal External- a line and coil repair product and AC SmartSeal Quick Shot, the 3 in 1 internal seal, lube and leak check dye. Interestingly, these two products work best together.   Mike discusses how and why he formed the company starting in his garage in 2014.   He describes his company’s focus on the technician, by making products that are safe, effective, and easy to use.   Part of this ease of use comes because all products are 100 % safe to the touch, non-toxic and non-flammable.  That means no warning labels and for our friends in California, no prop 65 issues. Plus, he backs up the product with 3rd party lab testing by Intertek   Mike’s got a lot to share with the industry.   You can buy Mike’s products at wholesalers across the US or online at www.trutechtools.com/Cool-Air-Products If you want to learn more you can reach out to Mike at www.CoolAirProducts.net or MikeWalton@CoolAirProducts.net

EP39 Learn about HVACR Chemicals & Sealants with Mike Walton of CoolAir Products

Today we turn the tables and your host becomes the guest! As you may or may not know Marilyn and I are building a new high-performance home this year (2019).   Even though I have been involved in home performance for 30 years, it was in the narrow field of test and measurement, not in construction detail and aspects.   And because it is our home and our money, everything about it is personal and I have a real hunger for the details which tends to complicate decisions!   So, I asked my thoughtful pal, Nate Adams to pitch some questions at me to get me to talk about the subject and share our journey up to this point.   We were calling it a high-performance house, but recently I’ve changed that to a new concept (in my mind): personalized performance – it’s what we want our home to be.   I hope you enjoy the listen.

EP38 Personalized Home Performance - Bill Spohn's new home construction Part 1

I’ve never thought about entrepreneurship when it comes to trade associations. I just thought they always existed.   Well, in the nascent world of building performance, I should have known better.   Listen in as we chat with Ryan Miller, the founder and executive director of the North Carolina Building Performance Association, as he describes his vision for the future of building performance.   He believes poor building performance is one big problem to solve and he aims to do it in his state by connecting all the stakeholders with education and information, as well as lobbying and training.   And he is not just stopping in his state as he supports and gets involved with like-minded organizations across the country.   Pay particular attention to the four points he notes in his strategic plan: Market Valuation Policy and legislation Work Force DevelopmentAnd Consumer Education   If you want to learn more you can reach Ryan via his website: www.BuildingNC.org 

EP37 From Building Plaques to Building Performance A discussion with Ryan Miller of NCBPA

Some of our listeners have likely heard of the term Home Performance.   But have you heard of Home Performance 2.0?   Michael Housh and Neil Comparetto join us to describe how they are helping to develop this new approach to serving customers with total home performance. This is a systems being developed by Nate Adams and Ted Kidd.   They describe a well performing home as one that is healthy, comfortable, safe, durable and, as a side benefit, uses less energy.   Michael and Neil are both trained and experienced HVAC technicians; mechanics in their own words.   They discuss how some simple changes in the approach to the way technical work is presented is resulting in better business and happier clients.   They describe the HP 2.0 process as consisting of 6 steps: client education, initial PAID consult, a comprehensive planning process, executing the project, QC, and continuous optimization with monitoring.   A large part of the client education consists of the resources available at www.NateTheHouseWhisperer.com – there you will find an inexpensive book that educates consumers (and techs!) on home performance, as well as 2 free downloads(chapters from the book)  to share with Clients: Home Comfort 101 and HVAC 101.   These steps help to remove the pain of being a residential HVAC business owner: (Much of this is based on the Sandler Selling Process)   Avoid fights over stuff you can’t fix   More Happy Clients - Actually SOLVE client problems, no band aids   Smooth out monthly sales with large HP projects in off seasons   Onboard Staff Faster-with something else for apprentices to do   Fewer Unhappy Clients   Reduce Mold Risk   Reduce Boredom with Challenging projects and new twists all the time   Reduce or eliminate free quotes   Increase Ticket Sizes w/o Home Performance Jobs   Lower sales and marketing costs, with better word of mouth and paid consultations.   Bigger, more satisfying jobs vs Small jobs with lots of up-front work that often don’t solve problems   If you want to learn more you can reach Michael at MHoush@HoushHomeEnergy.com and Neil at Neil@ComparettoComfort.com or Nate Adams and Ted Kidd at Nate@EnergySmartOhio.com
