The air indoors is rarely as clean as people assume.
Most San Diego residents spend the majority of their day indoors — at home, at work, or in school. Yet the air quality inside those spaces is almost never tested. Indoor air quality testing changes that. Using calibrated spore-trap pumps, digital hygrometers, and laboratory analysis, we evaluate how your indoor environment compares to outdoor baselines and to established health-based benchmarks.
We are particularly attentive to local factors. San Diego coastal humidity contributes to mold-friendly indoor conditions in Pacific Beach, La Jolla, Mission Beach, and Point Loma. Inland heat in El Cajon and East County stresses HVAC systems and creates condensation issues. Wildfire smoke events impact every neighborhood. All of these influence what we look for during an IAQ assessment.
What we measure during indoor air quality testing
Our standard IAQ assessment captures airborne mold spore concentrations through spore-trap sampling, indoor relative humidity and temperature, dew point, and visual indicators of particulate accumulation. We document HVAC condition, filter type and condition, ventilation paths, occupant complaints, and any sources of moisture or off-gassing that influence the indoor environment.
All air samples include at least one outdoor control. This is non-negotiable: spore counts have no meaning without a baseline. A house in La Jolla with 1,200 spores per cubic meter indoors may be entirely normal if the outdoor count is 1,800. The same indoor reading paired with an outdoor count of 200 is a very different story.
When to schedule IAQ testing
Symptoms among occupants are often the first signal: persistent headaches, sinus irritation, increased asthma frequency, sleep disturbance, or skin issues that seem to improve when away from the home. Other triggers include musty or chemical odors, visible mold growth, recent water damage, post-renovation indoor air complaints, and wildfire-smoke event exposure. New homeowners — especially in older Hillcrest, North Park, and Kensington properties — benefit from baseline IAQ testing during the first months of ownership.
What your IAQ report includes
You receive a PDF report with sampling locations annotated on a floor plan, all laboratory data including outdoor controls, indoor environmental readings, photo documentation, and a plain-language interpretation. Where elevated readings appear, the report identifies probable sources and the categories of intervention that would address them — improved ventilation, HVAC filtration upgrades, source-moisture correction, or, where genuinely indicated, remediation.
Healthier homes start with measurement
Every meaningful improvement to indoor air quality begins with knowing where you stand. Whether your goal is to confirm that your home is healthy, identify the source of a specific symptom pattern, or document baseline conditions for a sensitive family member, professional indoor air quality testing gives you the data to act with confidence rather than guesswork.
