Customers in Ocala, Florida, often ask how to offset the increased energy usage reflected on their electric bills during the hot summer months. Preventative maintenance will keep your HVAC system in top operating condition for maximum efficiency. Additionally, you shouldn’t block any air vents inside your homes. Covering HVAC vents will not conserve energy or decrease energy costs. In fact, it can result in the opposite.

Proper Airflow is Important

When you block a supply vent, air still pushes against it. This constant push of air to a blocked air vent can create an increase in pressure, and when combined with inadequate airflow, it can cause damage to your HVAC system’s heat exchanger. This damage can also lead to the exhalation of carbon monoxide and result in leaking ductwork. This problem will cost the homeowner more in energy usage over time.

Avoid a Buildup of Moisture

Central Florida residents know that when moisture builds up inside the home, it invites dangerous biological growth to develop. When you block your air vents, moisture can develop around them and the air ducts. Make sure your HVAC vents are not blocked by rugs, furniture or other household items.

Energy Efficiency is the Goal

One way to direct airflow within your home without adding stress to your HVAC system is to only partially close vents in rooms that aren’t in use. By partially closing less than 50 percent of the vents in your home, you can avoid disrupting the pressure within the ductwork. You’ll also keep the most inhabited areas of your home comfortable.
