How to Fix Weak Air Flow from Vents in Your House

A weak flow of air from your supply vents can create a number of problems throughout your living space, including poor air quality, discomfort, and increased energy bills.

Depending on the source, the issue may be resolved easily by the homeowner or may require the services of a licensed, experienced professional. Here is a list of some of the most common causes of weak air flow, along with solutions to restore comfort and efficiency to your home.

Call the knowledgeable professionals at National Heating and Air Conditioning at 513-399-5757 for expert HVAC installation, maintenance, and repair. Contact us online to schedule an appointment today!

Leaky Ducts

Gaps, cracks, or holes in your ductwork allow conditioned air to escape before it can reach your living space. In addition to forcing your HVAC system to work harder to reach the desired temperature, leaky ductwork can cause weak air flow from your vents in one or more rooms. A professional duct inspection can help to identify and locate any leaks to determine if duct sealing will resolve the issue.

Lack of Maintenance

An HVAC system that has been inadequately maintained may be in need of repair, replacement, or cleaning. If dirt has been allowed to accumulate within the ductwork or on system components, it may reduce efficiency or cause a blockage that hampers the flow of air. Schedule routine maintenance each spring and fall to ensure your equipment is cleaned, tuned, and optimized for peak performance.

Dirty Air Filter

A clogged or dirty air filter prevents the efficient circulation of air and causes your HVAC system to work harder to heat or cool your home. Change the air filter every four to six weeks during peak season or as needed and ensure your replacement filters are rated by the manufacturer’s recommendations for efficiency.

Blocked Vents

To function efficiently, your HVAC system needs an equal amount of supply and return air and an adequate amount of return air vents. Before calling National for service, ensure your supply vents are fully opened in each room and that no furniture or draperies are blocking the flow of air from your return vents.

Incorrectly Sized HVAC System

If your heating or cooling equipment is too big or too small for your home, you may experience a loss of comfort and a decrease in efficiency. Equipment that is too small may struggle to keep up with demand, while a system that is too large will continuously cycle on and off, never running long enough to achieve an adequate level of airflow.

The dedicated professionals at National Heating and Air Conditioning will perform a Manual J load calculation to ensure your new HVAC system is properly sized, and that the layout and sizing of your ductwork will maximize the flow of air throughout your home.
