It’s recommended to test your home’s indoor air quality at least once a year, or more frequently if someone in your household has respiratory issues. 72 Degrees Texas provides expert indoor air quality testing services to keep your home safe and comfortable.
The best way to test your home’s air quality is to start with a professional indoor air quality assessment. While at-home test kits exist, they often miss critical pollutants like VOCs, humidity imbalances, or allergens. At 72 Degrees Texas, we offer advanced diagnostics that go beyond surface-level readings—helping you pinpoint issues and build a cleaner, healthier home environment.
Improving your home’s air quality often starts with better ventilation, high-efficiency filters, and regular HVAC maintenance. But for lasting results, we recommend tailored solutions like whole-home air purifiers, dehumidifiers, and UV light systems. At 72 Degrees Texas, we design comfort systems that don’t just control temperature—they clean, balance, and freshen the air your family breathes every day.
Poor indoor air quality can stem from everyday culprits like pet dander, dust, mold, cleaning products, or even your HVAC system if it’s not properly maintained. At 72 Degrees Texas, we uncover the root cause using professional-grade tools and offer air quality upgrades that address everything from allergens to humidity—so your home stays as fresh as the Hill Country breeze.
We take indoor air quality seriously—because it’s not just about comfort; it’s about your health. Our team offers whole-home solutions, including air filtration systems, humidity control, duct sealing, and air purification. Whether you’re battling seasonal allergies or just want to breathe easier, 72 Degrees Texas brings decades of experience and a wizard’s touch to every IAQ fix.
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.
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.
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.
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.
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.
Improving indoor air quality is rarely a one-and-done fix. That’s why we also offer year-round services to keep your system running its best:
Seasonal HVAC maintenance with filter replacement and coil cleaning
Duct sealing and duct cleaning for better airflow and less dust
Thermostat upgrades that include humidity and air quality monitoring
Reliable AC and furnace repair, so your system doesn’t spread contaminants
Emergency response through our 24/7 HVAC service, because air problems don’t keep business hours
We also offer convenient membership through our Care Club, which includes priority scheduling, exclusive repair discounts, and two precision tune-ups per year—one heating, one cooling.
