Radon gas is a serious health threat that can accumulate in your home without any obvious signs. Because it is odorless, tasteless, and invisible, the only way to determine if your home has high radon levels is through radon testing. As an HVAC company in Ontario specializing in radon detection and mitigation, we help homeowners take the necessary steps to ensure a safe indoor environment.


How Do You Know If There’s Radon Gas in Your Home?

Unlike other indoor air pollutants, radon gas detection requires specialized testing equipment. There are two primary testing methods:


  • Short-term radon test (2-7 days): This test provides a quick snapshot of radon levels and is ideal for an initial assessment.

  • Long-term radon test (90+ days): Since radon levels fluctuate based on factors like weather and ventilation, a long-term test offers a more accurate picture of exposure.


Where Should You Place a Radon Detector?


For the most reliable radon testing results, detectors should be placed in the lowest level of your home where people spend time—typically the basement. Since radon enters through the ground, testing in the basement provides the best indication of your home’s risk level.


How to Pass a Basement Radon Test


If your radon test shows high levels, don’t panic! Our HVAC company specializes in radon mitigation solutions designed to bring your home’s radon levels to a safe range. Here’s how we help:


  • Sub-slab depressurization: A vent pipe and fan system is installed to safely redirect radon gas outside.

  • Sealing foundation cracks: Prevents radon from seeping into your home.

  • Improved ventilation systems: Enhancing airflow can help lower radon concentrations indoors.
