Ventilation / IAQ Verification

Whole-dwelling ventilation and local exhaust (kitchen and bath) measured and documented to the applicable standard for the project’s code cycle.

Tight envelopes make this the measure that surprises crews most often — undersized runs and throttled fans fail here, not at the equipment. Send us the ventilation design airflow with the booking and we’ll flag mismatches before the visit instead of on your final.
