Good Airflow Provides Comfort

3 Reasons for Weak Airflow and What to Do About This Problem

March 1, 2020

Are you experiencing problems with weak airflow in your Chambersburg, Pennsylvania, home? If so, you’re not alone. Airflow problems are some of the most common HVAC issues homeowners face, and they have a variety of causes. Here are three common problems that cause weak airflow in a home:

Dirty Air Filter

How long has it been since you changed your air filter? Filters collect dust and debris from the air, preventing them from entering your HVAC system and improving your indoor air quality. If you go too long without changing it, the filter can become clogged and impede airflow. To avoid this, change your filter about every three months. But check it monthly — if it looks dirty, go ahead and replace it early.

Ductwork Issues

Dust and debris that pass through a dirty air filter end up in your ductwork. There, they can build up and reduce airflow, particularly if your ducts are a little too narrow for your home. It’s also common for older ductwork to develop cracks and holes where air leaks out, resulting in airflow problems. If you suspect your ductwork is causing your issues, have it inspected to see if a duct cleaning would alleviate your problem.

Blocked Vents and Registers

Something as simple as a blocked vent can cause major airflow issues. To properly heat and cool your home, your HVAC unit needs to disperse air through each vent freely. A closed or blocked vent impedes the system’s ability to disperse air, resulting in weak airflow.

Check all the vents and registers and make sure they’re open and not blocked by furniture. It’s also a good idea to wipe them down with a damp cloth and vacuum away any dust accumulation from time to time.
