Indoor air quality testing is a hot accessory product for HVAC companies trying to sell air scrubbers. We're not one of those. You get real measurements against real benchmarks (EPA, ASHRAE, WHO), and a plain-English explanation of what's elevated, what's fine, and what to actually do about it.

The IAQ testing process

What actually happens in your home.

01

Site walk and baseline

Walk the space, identify likely sources, set instruments in representative rooms.

02

Particulate sampling

Calibrated PM2.5 and PM10 readings across rooms, returns, and near any suspect sources.

03

VOC + humidity logging

4–24 hour datalog depending on scope. Captures episodic spikes from cleaning products, HVAC cycling, etc.

04

Airborne spore count

Indoor air-o-cell samples plus an outdoor control. Lab-analyzed by independent lab.

05

Written report

Within 7 business days. Charts, benchmarks, and prioritized recommendations (if any).
