What Happens During an Indoor Air Quality Assessment?
A real IAQ assessment checks four things in sequence: indoor humidity levels, ductwork for leaks or disconnections, your current filtration setup against your system's capabilities, and a visual inspection for mold or moisture damage in accessible areas. Each step targets one of the root causes covered in what's in your indoor air.
Step 1: Humidity Reading
We measure indoor relative humidity against the 30-50% comfort range (with 60% as the mold-risk threshold) to establish whether your home needs active humidity control or whether your AC alone is keeping up.
Step 2: Ductwork Check
Leaky or disconnected ductwork pulls unconditioned, unfiltered air from attics or crawlspaces directly into your home's air supply — undermining filtration and humidity control at the source, no matter how good your equipment is.
Step 3: Filtration Review
We check your current filter's MERV rating against what your system can safely handle, and whether a whole-house filtration upgrade or a targeted portable unit makes more sense for your specific concerns.
Step 4: Visual Mold and Moisture Check
We visually inspect accessible areas — around the air handler, in crawlspaces, near exterior wall corners — for signs of moisture damage or mold growth that point to a humidity problem that's already begun causing damage.
What You Get at the End
A straightforward report: what we found, what's actually causing your specific air quality concern, and — only where it applies — what fixing it would involve. We don't recommend a whole-house system if a filter upgrade solves your actual problem.

Frequently asked questions
How long does an indoor air quality assessment take?
A typical assessment takes under an hour, covering humidity, ductwork, filtration, and a visual moisture check.
Will you tell me if I don't need anything?
Yes — if your current setup is already handling your home's air quality well, we'll say so rather than recommend an upgrade you don't need.
Does the assessment include testing for mold spores in a lab?
Our assessment is a visual and mechanical inspection, not a lab air-sample test — if we see signs that warrant lab testing, we'll refer you to that step specifically.
What's the most common issue you find during these assessments?
Humidity running above the recommended range, often paired with a filtration setup that's not matched to what the system could actually support.
Do I need to be home during the assessment?
Yes — we need access to the air handler, ductwork, and any problem rooms you've noticed issues in.
