Weak HVAC airflow is caused by several factors. From dirty air filters to leaking ducts, there are many reasons your cooling system is releasing inadequate air. Some of these can be easily addressed, while others require professional help.
Read on as a reputable HVAC contractor shares the common factors that cause poor HVAC airflow and tips on addressing the issue.
Clogged Air Filters
Problem: The main function of your air filters is to filter out contaminants and pollutants. If they are filled with debris, they can block the airflow. This will result in weak airflow, hot and cold spots in your home, and system breakdown.
Solution: Change your air filters every one to three months, depending on your usage. Ideally, you should clean your filters after around 250 hours of use and change them at least once every three to four months. If you live in a humid climate or a highly polluted area, you might need to do it more frequently.
Faulty Thermostat
Problem: It may seem like your thermostat has nothing to do with the problem, but it can impact your HVAC airflow. If your thermostat is not calibrated correctly, has malfunctioned, or has developed dust buildup, it can result in insufficient airflow.
Solution: Check the batteries if you have a battery-operated thermostat. If they are working fine, open the cover and check for dust and debris. Using a soft brush, remove all the grime stuck inside your thermostat. For more specific advice, consult a heating installation and maintenance professional.
Blocked Vents
Problem: If there’s no air blowing from the vents in your house, something might be blocking them. A piece of furniture might be in front of the vents, or you might also have closed some vents on a chilly day and forgotten to open them again. This action compromises the HVAC airflow.
Solution: Inspect all of the vents in your house. Open the closed ones or remove any blockage.
