Can You Fix Cold Air Coming Through Your Range Hood?

Can You Fix Cold Air Coming Through Your Range Hood? - Proline Range Hoods

The Problem

Cold air entering through your range hood causes discomfort and increases heating bills. This happens because when your hood isn't running, outside air can flow backward through the ducts into your kitchen. This usually happens because of negative pressure in the kitchen.

This intrusion can lower kitchen temperatures, leading to discomfort and higher energy bills.

Understanding the mechanics of cold air infiltration helps in choosing effective solutions. This knowledge can guide choices in both new installations and existing systems.

The Solution: Backdraft Dampers

A backdraft damper is the most effective sol ution. It's a simple device that:

  • Installs in your hood's ductwork
  • Opens when the fan is on to let air out
  • Closes automatically when the fan is off to prevent cold air from coming in

Yes it is as simple as that, check them out HERE. Backdraft dampers are crucial for blocking cold air from entering your kitchen.

Without backdraft dampers, cold drafts can disrupt comfort. Investing in quality dampers is essential for maintaining a cozy environment.

  3. Consider a duct insulation wrap - This prevents temperature changes in the ductwork
  4. Regular maintenance - Clean filters monthly to maintain proper airflow
