From Adam Mufich (NCI): When Exhaust Fans Backfire

A homeowner runs five bath fans after every shower, trying to fix sweating registers. The moisture gets worse. A high-performance home drips condensate from a hallway light fixture with no plumbing above it. Neither problem is an equipment failure, and neither one shows up in a standard service call.

In his latest guest article on measurequick.com, Adam Mufich of NCI walks through two real cases where the root cause was building pressure, not equipment performance. The bath fans depressurized the house so severely that they pulled hot, humid outdoor air in through every gap in the envelope, pushing indoor humidity above 70%. The dripping fixture traced back to clogged ERV intake screens that shifted the entire house negative, drawing moisture through building cavities onto a cold duct surface.

This is what NCI's High Performance HVAC approach looks like in the field: treat the building as a system, measure what you cannot see, and let the data point you to the real problem. measureQuick was built for exactly that workflow. When Adam deployed psychrometers, mapped dew points room by room, and read pressures through the Probe Manager, the data told a story that visual inspection never could.

The contractor who can explain why a register sweats, prove it with measurements, and fix the actual cause is the contractor who stops competing on price. That shift from parts changer to trusted advisor starts with treating every call as a system diagnostic, not a component swap.

NCI High-Performance HVAC Summit: September 1-3

The 23rd Annual NCI High-Performance HVAC Summit is coming to Pigeon Forge, TN, and measureQuick is a proud sponsor. This is the only conference in the industry built entirely around High Performance HVAC, with three tracks covering business, sales, and technical content led by active contractors and industry experts.

Jim Bergmann is presenting three sessions this year. Whether you want to sharpen your diagnostic process, build a performance-based sales strategy, or make High Performance HVAC the culture of your company rather than a side project, the Summit delivers practical, take-it-home material. Attendees earn up to eight NATE continuing education units, and the conference is open to all HVAC professionals, not just NCI members.

Only 50 spots remain. If you have been thinking about it, now is the time to register.

Brian Feenie walks through mQ Assist: ask it a question while your tools are live on a system, and it reads your actual measurements to tell you what is happening, what to check next, and how to explain it to the homeowner. Think of it as Jim's field knowledge, available on every call.
