Discerning the Data There exists a misunderstanding in the relationship between duct and envelope leakage. Our industry primarily focuses on duct seal. A duct system can be sealed extensively at rough and pass inspection, then the envelope leakage fails at final. If we dissect the information we find leakage has migrated from duct to envelope, and if we view the two categories as separate entities (two closed systems) we will begin to understand how this happens. This revelation will bring us to the conclusion that if the envelope leaks significantly, the size of the HVAC will never be sized correctly. On a windy day, pressure will drive loads in or out. When ambient temperatures call for conditioning, fan pressure will induce more ambient air since the structure is open. While the idea is fundamental to those who understand the mechanics of air sealing, and insulation it is largely ignored in segments of our industry.

Today’s Market HVAC equipment sales in July 2025 were down 27% over 2024. Some

brands are down by over 40% for the same time last year. Trane, Carrier, and Lennox all agreed the market is in as tough as any time over the last decade. With sales slowing it may force some companies to rethink market strategy. The market has quickly transitioned from replace to repair. The residential construction industry is moving to a remodel market. This market transition means there is an opportunity to focus on getting HVAC remodels and replacement work done correctly. For every ten homes

you drive by there are eight that could use work that does not necessarily call for equipment replacement. Personally, I believe this transition will be

The duct system must be sealed thoroughly, but equally important is the fact that framing, air,

and insulation boundaries must be aligned. Shared areas of failure are cabinet furr downs, areas left unfinished or absent behind lavatories and sink installations. Remodeling is where significant abuse takes place with materials looking good but failing to
