Why Indoor Air Quality Matters in Troy, IL

Troy is a thriving community with a growing population, but hidden air quality risks can pose a threat to homeowners. Studies show that homes in Madison County, including Troy, have been exposed to moderate levels of radon gas. This naturally occurring radioactive gas can seep into homes through cracks in foundations and basements.

Additionally, seasonal humidity, allergens, and mold growth can contribute to poor air quality, affecting respiratory health. Our services ensure that your home remains a safe haven by addressing these concerns with expert testing and mitigation solutions.

Radon Testing & Mitigation in Troy, IL

Radon in Troy: What You Need to Know

According to the EPA, Madison County is classified as a Zone 2 Radon Area, meaning indoor radon levels typically range from 2 to 4 pCi/L—levels that may require mitigation. Since radon is odorless, colorless, and invisible, professional testing is the only way to determine if your home has unsafe levels.

Did You Know?

  • Troy, IL, has recorded radon levels exceeding the EPA’s action threshold of 4.0 pCi/L.
  • Radon exposure is the second leading cause of lung cancer in the U.S.
  • The Illinois Emergency Management Agency (IEMA) recommends testing every five years.

Our Professional Radon Testing Services

At Air Sense Environmental, we provide fast, reliable, and accurate radon testing using EPA-approved calibrated monitors. Our process includes:

  • 48-hour radon monitoring for precise results
  • Same-day reporting for quick decision-making
  • Guidance on next steps if radon mitigation is needed

Radon Mitigation for Troy Homes

If your home tests high for radon, our customized mitigation systems effectively reduce exposure. Our solutions are tailored to your home’s:

  • Foundation type (basement, crawl space, slab)
  • Existing radon levels
  • Ventilation requirements


We use state-of-the-art radon mitigation technology, including sub-slab depressurization (SSD) systems, to redirect radon safely out of your home. Regular testing ensures continued effectiveness for long-term protection.

Indoor Air Quality Testing & Air Purification

Beyond radon, Troy homes are vulnerable to indoor pollutants, allergens, and humidity issues that can impact respiratory health. Our indoor air quality testing services provide a complete assessment of airborne contaminants, including:

  • Mold spores & bacteria
  • Pet dander & allergens
  • Carbon monoxide & volatile organic compounds (VOCs)
  • Viruses & airborne pathogens

Using the Model 5200 IAQ Monitor, we provide real-time air quality tracking, ensuring you receive a detailed analysis and customized recommendations for air purification.

Advanced Air Purification Solutions

We don’t just detect air quality issues—we solve them. Air Sense Environmental installs high-efficiency air purification systems featuring AprilAire technology, ensuring:

  • Elimination of airborne contaminants
  • Balanced humidity control
  • Improved respiratory health

Crawl Space Encapsulation in Troy, IL

Troy’s humid climate and unpredictable weather patterns make homes vulnerable to moisture problems, especially in unfinished crawl spaces. Left unsealed, a crawl space can cause:

  • Mold and mildew growth
  • Structural deterioration from wood rot
  • High indoor humidity levels
  • Increased allergen exposure

Our crawl space encapsulation process protects your home by:

  • Sealing off crawl spaces to prevent external moisture intrusion
  • Installing high-efficiency dehumidifiers (AprilAire models)
  • Reducing humidity levels for improved air quality

By encapsulating your crawl space, we enhance structural integrity, reduce allergens, and improve indoor air quality, creating a healthier living environment.
