A tight house with no planned ventilation is not an efficient house. It is a stale one. After a remodel or a duct changeout, indoor air quality is often the first thing occupants notice and the last thing the original plans mentioned.
We measure. We look at returns, filter slots, bath fans that dump into the attic, and kitchens that depressurize the whole floor. Then we write a short list of corrections that HERS/ECC field verification can actually prove.
This is building-performance work — airflow, filtration, and pressure — not an HVAC or plumbing contracting pitch. If you need the rating, we test it.
