Can Running the HVAC Fan Continuously Save on Energy Costs? Part 3 of 3

Part 3 – Environmental Concerns – Radon Gas

Radon gas is the leading cause of lung cancer among non-smokers, and it’s the second leading cause of lung cancer for smokers. It’s a radioactive gas that you can’t see, smell or taste. It comes from the soil and is pulled into your home due to pressure differences between the inside and outside of the home.

If you haven’t tested your home for radon gas yet, I would encourage you to do so. One out of fifteen homes in the US have a radon problem, and the only way to know is to test. If you have tested your home for radon gas, and running the blower motor continuously is something new for you, then you should test for radon again. Testing is very easy to do and doesn’t cost very much. For more information about radon, check our radon information here.
