Indoor Air Quality Testing in Charleston
Most HVAC companies guess. We measure. Every Ai-R Pro diagnostic begins with an instrument-led assessment of the six properties that actually define your indoor air. You don’t get an opinion. You get a written report.
What We Actually Measure
Temperature & Humidity
Room-by-room dry bulb, relative humidity, and dew point that determines whether your home feels sticky at 72°F.
Particulate Matter (PM2.5)
Fine particles from pollen, smoke, cooking, candles. The biggest IAQ pollutant in most Lowcountry homes.
VOCs
Volatile organic compounds from off-gassing furniture, paint, cleaners, fragrance. We tell you what is normal and what is not.
Carbon Monoxide
Low-level CO from gas appliances, garages, combustion. Levels you would never notice until a headache sets in.
Pressure & Airflow
Room-by-room pressure balance and CFM at the registers. Imbalance causes hot rooms, mold, and humidity.
Equipment Performance
Refrigerant charge, airflow per ton, capacity, efficiency — live, on your system — via MeasureQuick.

Why Charleston Homes Need This
Lowcountry Humidity
Dew points above 70°F for months at a time. Standard ACs cannot keep up.
Coastal Salt
Crawlspaces, ductwork, and equipment in coastal homes degrade faster — and quietly.
Older Housing Stock
Historic homes, retrofits, and add-ons stack up over decades. We untangle the system.
Common Questions
How long does the test take?
60 to 90 minutes for a single-system home; up to 2 hours for multi-system or larger homes.
Do I need to leave?
No. We work around your day. We may ask you to avoid cooking or strong cleaners during the visit.
What if readings are fine?
Great news. You get the report anyway — a documented baseline.
