Symposium – What is the House Trying to Tell Me?

By Chris Hughes Adam Mufich Tessa Murry

Join Chris Hughes and Adam Mufich at the 7th Annual HVAC/R Training Symposium as they interview building scientist Tessa Murray. In this eye-opening conversation about what your house is really trying to tell you. Discover why HVAC techs need to understand building science fundamentals to truly master their craft.

What You’ll Learn:

The critical connection between HVAC systems and building science
How to identify hidden moisture problems in walls and attics
Combustion safety testing that could save lives
Understanding dew points and thermal bridging
Proper ventilation strategies for different climate zones
Why duct leakage testing is just the beginning

Key Topics Covered:

Transition from cold climate (Minnesota) to hot/humid (Florida) building science
Ice dams, ghosting, and crying houses explained
The house as a system approach for HVAC professionals
Blower door testing and pressure diagnostics
Indoor air quality concerns and solutions
Natural draft appliance safety considerations
Wall assembly moisture management
Occupant behavior impacts on building performance

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this episode, Bryan sits down with Leilani for an introduction to GRIT Camps — the hands-on program that brings skilled trades exposure to youth ages 12–17 through community events led by working tradespeople. Leilani explains that a GRIT Camp pairs recruited mentors with students for a day of modules covering safety, carpentry, electrical, brazing, and plumbing, including torch work, PVC and copper fitting, and disassembling HVAC components. Students also learn to read a jobsite-style blueprint and receive a six-in-one screwdriver to take apart and explore. Bryan and Leilani emphasize that while GRIT supplies the curriculum, guides, and structure, the host — typically a contracting business or trade organization — owns the event: recruiting students and mentors, securing a venue, and building real community connections around the day.

A large portion of the conversation walks through who does what. Hosts provide the facility, materials (plywood, 2x4s, copper, PVC, and more, all detailed in GRIT’s guide), and lunch for up to around 30 people, plus a local host facilitator to coordinate logistics and serve as GRIT’s point of contact. Mentors must be certified skilled tradespeople who complete GRIT’s required video course and pass a background check before working with students; volunteers who don’t interact directly with kids are not required to undergo a background check. GRIT, in turn, supplies the camp curriculum, host and mentor guides, registration and marketing materials, badges, student blueprints and PPE, background check coordination, and on-site program leadership from staff like Ty, GRIT’s head of training, who typically arrives the day before to walk the facility with the host.

Bryan and Leilani also dig into planning specifics: camps run from about 9:30 a.m. to 3:30 p.m., cap out at 16 students with a two-students-per-mentor ratio (so eight to nine mentors for a full camp), and generally need 10 to 12 weeks of lead time to hit deadlines for mentor certification, materials gathering, and student registration. They cover the realities of choosing a torch and joining system — MAPP gas and propane versus oxyacetylene for brazing, and why oxyacetylene can’t be used for the popular aluminum-repair activity — along with commonly overlooked items like correctly sized Forstner bits, spare drill batteries, extension cords, and pre-cut lumber. They close with guidance on budgeting (camps typically run $1,500 to $5,000), sourcing a sponsored lunch, handling allergies, inviting community press, and what makes a camp genuinely successful: preparedness paired with passion from both mentors and hosts.
