What size fan do we use?

At Regina Radon Solutions we use Pressure Field Diagnostics (PFD) to size the proper fan: Why “Sizing It Right” Matters for Your Radon Mitigation System

When it comes to protecting your home from radon, customization is everything. Even Health Canada’s Radon Reduction Guide for Canadians emphasizes how crucial proper system design is.

Undersized vs. Oversized Systems — Why It Matters

Undersized Systems

An underpowered fan won’t reduce radon as effectively — and when it comes to radon, “lower is always better.” A 90% reduction is good, but 98% is even better.

Undersizing can also overwork the fan, shortening its lifespan (think towing a tractor-trailer with a Mini Cooper

Oversized Systems

Bigger isn’t always better:

More Noise – Fans that sound like jet engines aren’t fun to live with.

Higher Heating & Cooling Costs – Excessive airflow can pull your warm or cooled air right out of the house.

Backdrafting Risks – Too much suction can pull carbon monoxide back into the home from appliances.

Frozen Pipes – In rare cases, cold air pulled under the slab can freeze plumbing.
