Why You Should Never Cover Any of Your Home’s HVAC Vents

Have you toyed with the idea of covering your HVAC vents to redirect air elsewhere or reduce your energy expenses? Unfortunately, this common HVAC myth does more harm than good and could have severely damaging effects on your Yuma home’s energy efficiency, comfort, and even your HVAC system’s life span. Keep reading to find out why you should avoid closing air vents.

Pressure Buildup

When you cover a vent, your HVAC system doesn’t register that action. Your system will keep pumping air to closed vents. The closed vents may result in increased air pressure and inadequate air movement. Both of these issues could lead to a number of problems.

Ductwork Leaks

The increased pressure in your air ducts can make them crack and tear, allowing air to escape. Your HVAC system will have to work harder to compensate for the lost air, resulting in higher energy bills.

Reduced Comfort

Closing vents disrupts the delicate airflow balance. Airflow into some rooms will increase, whereas other rooms will receive less-conditioned air, making them harder to heat or cool. That will cause temperature inconsistencies and compromise your home comfort.

HVAC Equipment Breakdowns

Shutting HVAC vents could lead to costly HVAC equipment breakdowns and repairs. The buildup of air pressure could cause your heat exchanger to crack and allow carbon monoxide to leak into your home. Restricted airflow could cause your AC evaporator coil to freeze and the compressor to break down. What’s more, when your HVAC system is constantly straining, its life span will significantly reduce.

Covering HVAC vents ends up costing much more in repairs, replacements, and energy bills. Keep your HVAC vents open and ensure that no furniture, rugs, or curtains are accidentally covering them.
