Keep Your Vents Open & Clear

Do you have rooms in your home that are unused? Don't close the vents! Your HVAC system produces the same amount of warm or cool air. Covering or closing vents could increase your chances of damaging the system, here's how:

Restricted Air Flow

When excess air is forced to flow in another direction, it can compromise your home's temperature.

Excess Spending

Restricted or blocked airflow makes your system work harder to regulate your home's temperature. It will run more often, causing higher monthly bills.

Heat Exchanger Damage

Blocking the natural airflow can cause buildup of air pressure, leading to problems with the heat exchanger. This pressure can cause the exchanger to crack, leaking carbon monoxide.

Air Duct Issues

Increased air pressure causes the ducts to wear down faster, especially in older homes that can crack or create leaks more easily.
