Why You Shouldn’t Cover Your Air Vents

Why You Shouldn’t Cover Your Air Vents

At some point in time, the idea of covering your air vents to save energy started becoming common practice. However, even if this idea has good intentions, it can have bad consequences. Unless you want to seriously mess with your HVAC system, you shouldn't cover your air vents. Here’s why:

Pressure Buildup

While you may know that certain vents are closed or blocked off, your heating system doesn't. It will continue to push air to those vents like it was designed to do. If the air isn't able to exit your ducts, a pressure build-up can develop inside them and damage your ducts and heating system.

Carbon Monoxide Leaks

You know that pressure build-up we just mentioned? If that pressure ends up traveling back to your heat exchanger, it can cause the part to become damaged or cracked, allowing carbon monoxide to leak out of the exchanger and into your home. If you don't have a functioning carbon monoxide detector, you and your family could suffer the dangerous consequences of the silent killer.

Mold Growth

Especially when there's warmer weather outside, if air isn't able to exit your ducts due to covered air vents, mold or mildew can start to grow around the vent. While you may be able to spot it on the outside, mold growing inside the vent may go undetected and spread further throughout your duct system and home.

Higher Energy Bills

Some people think covering your air vents will help save you money on your energy bills. However, if a pressure buildup causes your air ducts to develop cracks or leaks, you'll actually waste more energy and have higher energy bills since you'll be losing the treated air before it reaches the rooms in your house.
