Some Quick Facts
The best time to conduct your radon test is during the heating season. Radon levels vary from day to day and from season to season, and the highest radon levels are generally found during the winter when our homes are sealed more tightly than during the summer months.
During winter indoor air is warmer than the surrounding soil, which tends to pull more radon gas inside.
During the summer, open windows provide good ventilation and will often reduce the radon levels inside a home.
For these reasons, it’s best to test for 91 days during the heating season to get the best picture of the radon levels inside your home.
