Are you frustrated with your heating system’s weak airflow? Here are the top 5 reasons why this problem is most likely occurring, along with tips to solve the issue.

1. Partially Closed Air Vents Registers

Check the covers over your air vents to make sure that they’re open all the way. There’s usually a lever next to the grill that you can move side to side or up and down to open the air vent as much as possible.

2. Air Filter Issues

A dust-clogged air filter is one of the most common reasons for weak airflow. If there’s a layer of dust blanketing the filter, air will struggle to flow through, and your system will have less air to push out. If your filter is new, it’s also possible that the filter efficiency rating is too high for your system to handle. You may need to downgrade your air filter and see if that improves your system’s airflow.

If you need a system with powerful filtration because of allergies, asthma, or other reasons, you might want to consider installing an air scrubber, rather than relying on an air filter.

3. Problem With the Blower

The blower is the part of your system that circulates air throughout your home. If there’s an issue with its motor or mechanisms, you can end up with significantly reduced airflow and an extremely inefficient system.

4. Air Leaks

Have your air ducts been professionally sealed? If not, you could be losing 20 to 30 percent of the air your heater is trying to send out due to leaks. Air leaks can also occur around air vent covers, so most homeowners can improve their system’s airflow and efficiency by making sure to seal these crucial areas as well.

5. System Age

If your heating system is 15 years old or older, the weak airflow could simply be a sign of old age. According to the National Association of Home Builders', furnaces last about 15 to 20 years on average, and heat pumps last about 16 years on average.

When replacing your HVAC system, it’s important to consider energy-efficient and low NOx options, especially in Orange County, where regulations are tightening on greenhouse gas emissions.
