Problems we solve
A healthy home starts with knowing what you’re breathing.
Many houses draw some of their replacement air from places nobody would choose to breathe from. How much depends on the leakage paths and pressure differences in your particular house — and that can be tested for.
Sound familiar?
Air doesn’t come from nowhere.
When a house is short of air, it takes it from wherever it can — the crawlspace, the attic, the attached garage, the gaps around a basement rim joist. Whatever is in those places comes with it: humidity, dust, odors, whatever is stored down there.
Filters and purifiers might clean the air that’s already inside, but they don’t change where the air is coming from. A healthy house starts by controlling how the air enters in the first place.
EPA studies of human exposure have found that indoor levels of some pollutants can run two to five times higher than outdoor levels — and occasionally more than 100 times higher.
What people tell us
- Dust is back on the surfaces a day after cleaning
- The house smells stuffy, especially in the morning
- You can smell the garage, the basement or the crawlspace indoors
- Allergy symptoms are worse inside than outside
- Cooking smells hang around for hours
- Closed rooms feel stale, even with the system running
You don’t have to have all of these. One is enough to be worth testing.
What usually causes it
Where the air is really coming from
These are the causes we find most often. Our testing reveals what those causes are.
-
Air pulled from places you’d never live in
a crawlspace, an attic, an attached garage — and it brings their smell and their dust with it.
-
Leaks on the return side of the duct system
pull unfiltered air straight into the system and blow it around the house.
-
No plan for fresh air
means the house ventilates by accident, through whatever gaps it happens to have.

How we find it
We find out where your air is coming from.
We choose the tests based on your house and what it’s doing. Not every house needs every test.
-
Blower door testing
Tells us how leaky the house is, and helps us find the openings connecting it to outdoors and to spaces like the crawlspace.
-
Pressure diagnostics
Show which spaces the house is pulling air out of when doors close and the fan runs.
-
Pressure pan readings
Flag the duct runs strongly connected to an attic or crawlspace, including return-side leaks pulling that air into the house.
-
Humidity and ventilation
Whether the house is getting fresh air deliberately, or by accident from the wrong places.
We don’t test for radon, mold or specific contaminants. What we do is help determine the underlying causes — the pathways bringing outside air, crawlspace air and garage air into the rooms you live in — and refer any further work to local specialists.
On your own
A monitor tells you what and when. Testing tells you why.
An indoor air quality monitor sits on a shelf and watches the air all day. Depending on the model it tracks temperature, humidity, carbon dioxide, particulates, VOCs or radon — so you learn both what is in your air and when it changes. That’s genuinely useful, and we think every house should have one.
What it can’t tell you is where that air is coming from. A monitor reading high every evening doesn’t know whether the cause is ventilation, a closed-off room, or a return duct pulling from the crawlspace. That part takes testing.
Monitors worth owning
- Haven IAQ room monitor — the one we recommend most often
- Airthings View Plus — broad coverage in one device, radon included
- Aranet CO2 & Radon Monitor — for carbon dioxide and radon specifically
Watch the trend rather than any single reading — cheaper sensors drift over time, and most VOC numbers are relative rather than absolute.
The Airthings and Aranet links are affiliate links: buy through one and we may earn a small commission, at no extra cost to you. The Haven link isn’t. We recommend all three because we use them, not because of the commission.
What you get
An answer you can act on.
One to three days after the visit you get a video Home Performance Report — a walkthrough of your own house showing what we tested, what it means, and what we’d do about it, in the order we’d do it.
In your report folder
- Video Home Performance Report
- Every photo and video from the inspection
- Thermal images
- Your test results
- Prioritized recommendations
- Product links
- Local contractors we trust
Then it’s your call. Do it yourself, hand the report to your own contractor, or have us manage the work. See what an inspection covers.

You breathe the air in your house more than the air anywhere else. It’s worth knowing where it comes from.
