When most people think about air pollution, they picture smoggy skies or factory smoke—but some of the most harmful air you breathe might be right inside your own home. Indoor air can be up to five times more polluted than outdoor air, especially in well-sealed, energy-efficient homes where dust, allergens, and contaminants have nowhere to escape.
That’s where 72 Degrees Air Conditioning, Heating, and Plumbing comes in. Since 1986, we’ve helped families across Fredericksburg and the Hill Country reclaim their indoor air through honest guidance, professional indoor air quality testing, and custom solutions designed to protect your health and comfort.
What Is Indoor Air Quality Testing?
Indoor air quality (IAQ) testing is a diagnostic service that evaluates the cleanliness, safety, and balance of the air inside your home. Using advanced tools and professional-grade monitors, our trained technicians measure levels of dust, mold spores, pet dander, carbon monoxide, formaldehyde, humidity, and more.
Whether you’re experiencing allergy symptoms, noticing musty smells, or just haven’t had your air evaluated in a while, testing your indoor air gives you peace of mind—and a game plan to make it better.
Signs You Might Need an Air Quality Test
Not sure if your home needs an IAQ checkup? Common signs include:
-
Unexplained headaches or fatigue
-
Persistent allergy or asthma flare-ups
-
Dust buildup despite frequent cleaning
-
Musty or stale indoor odors
-
Excess humidity or dampness
-
Poor air circulation or hot/cold spots
Our certified experts at 72 Degrees will identify the source of the problem and recommend targeted improvements—whether that’s ventilation upgrades, air filtration, humidity control, or ductwork repair.
What We Test For—and Why It Matters
Indoor air quality testing is about more than comfort—it’s about your health. We assess a wide range of contaminants and environmental factors, including:
-
Particulate matter (PM2.5 and PM10) – Dust, pollen, and pet dander that affect breathing
-
Volatile organic compounds (VOCs) – Gases released from cleaning products, paints, and furniture
-
Carbon monoxide (CO) – A dangerous, odorless gas that can leak from furnaces or gas appliances
-
Humidity levels – Too much moisture invites mold; too little can dry out skin and sinuses
-
Mold spores – Often invisible but potent triggers for allergies and respiratory issues
And because your HVAC system plays a central role in circulating air, we often pair our testing with duct inspections, filter checks, and airflow evaluations to ensure clean air is actually reaching every room.
Solutions Backed by Testing
Unlike one-size-fits-all products, our solutions are based on what your home actually needs. After testing, we may recommend:
-
High-efficiency air filters or whole-home air purifiers for cleaner circulation
-
UV lights to kill bacteria and mold within your HVAC system
-
Dehumidifiers or humidifiers to keep moisture levels balanced year-round
-
Duct cleaning or sealing to prevent pollutants from cycling through your air
-
Smart thermostats for automated humidity and air quality control
-
Fresh air ventilation systems that improve circulation and reduce indoor air stagnation
We tailor every recommendation to your space, your goals, and your budget—just honest guidance and expert service, the way it should be.
