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 a competent HVAC or insulation contractor can actually execute.
If you need medical-grade filtration, we will size the real constraint — the return, not the merchandising on the box.
