Low Airflow Guide

HVAC Company in Cincinnati, OH

The efficiency and performance of your HVAC system are determined by the quality and installation of your equipment, maintenance practices, and airflow. If your energy bills have increased while comfort has decreased, optimizing your home’s airflow may help you save money on heating and cooling costs year-round.

National Heating and Air Conditioning is pleased to offer the following tips for improving airflow throughout your home, which can yield instant and long-lasting results for your home!

Are you experiencing issues with low airflow in your Cincinnati home? Call National at 513-399-5757 to schedule an appointment or contact us online today! 

Increase Air Circulation

Attempting to divert conditioned air from one room to another by closing one or more vents can have an undesirable result. By intentionally blocking the flow of air, your HVAC system will have to work even harder to combat the increase in air pressure. The added pressure may also force the conditioned air to escape through small cracks or gaps in your ductwork, decreasing comfort and efficiency even further.

Change Your Air Filter

An air filter is designed to trap particulate and prevent it from circulating throughout your HVAC system. As the filter becomes clogged or dirty it is necessary to clean or replace it to improve the quality of your indoor air and increase efficiency.

The type of air filter you choose should be based on the manufacturer’s recommendations for your heating or cooling system, typically ranging between a MERV rating of 8 to 13. Although a higher rating is better, choosing an air filter with a rating that is too high for your system will result in a decrease in efficiency if the fan is not powerful enough to push conditioned air through the filter.

Give Your Fan a Break

While you may be tempted to leave your HVAC fan running continuously in an attempt to cool your home, all you will really do is recirculate the air and drive up your electricity bill—not lower the temperature.

Schedule Annual Maintenance

A clean, tuned, well-maintained HVAC system will operate at peak efficiency. During your appointment, one of our trained technicians will perform a thorough inspection to determine the cause of your low airflow and provide the best solution to resolve the problem.

Add More Insulation

Attic insulation prevents the transfer of heat between the attic and your living space below, but if levels are insufficient, you may lose heat in the winter and gain heat in the summer. Attic ventilation is also important for airflow, and it’s imperative that intake and exhaust vents are present and unobstructed by insulation or other materials.

Seal Your Ducts

Up to 30 percent of your conditioned air may be lost due to leaky ducts, causing your HVAC system to work even harder to achieve the desired temperature. Airflow can be restored by sealing holes and cracks and repairing areas where ducts may have become disconnected.

Schedule a Home Energy Audit in Cincinnati, OH

A home energy audit from National Heating and Air Conditioning can determine the efficiency level of your home and identify problem areas which may be causing low airflow.
