Your home's HVAC system relies on consistent airflow through the unit and your vents to maintain your home's temperature. However, when the airflow through your vents seems weak or just isn't enough to keep up with your home's needs, there are some things that you can try to help improve that airflow and keep your home more comfortable when your HVAC system runs. Here are some tips to improve your HVAC system's airflow.
Replace The Air Filter
The most common reason for low airflow in your HVAC system is a dirty air filter. When the air filter is clogged with dirt, it cannot allow enough air into the system for the furnace to push sufficient air out. That's why the air filter is so important. If you've noticed that your HVAC system is not releasing as much air, replace or clean the air filter first to see if that solves the problem.
Check The Air Vents
Make sure that all of the air vents in your home are open. A closed air vent, even if it isn't in the affected area, can disrupt the airflow from your HVAC system. Check all of the air vents to be sure that they are open, and check inside the vent duct to make sure that there's nothing clogging the system.
Inspect Your Air Ducts
If you're certain that your HVAC system is putting out sufficient air, but that air isn't reaching your vents, it has to be going somewhere. Inspect the full length of the air ducts for any potential cracks, gaps, or other sources of leaks. If the air is escaping somewhere along the ductwork, you can fix the problem by sealing the gap. If you can't find the source of the problem, you may need to have an HVAC technician inspect the ducts to find the source of the problem.
Assess The System Design
If your HVAC system has never been sufficient, and you've eliminated the filter and airflow as the sources of the issue, you may want to look at the design and capacity of the system. Have an HVAC contractor evaluate the system's layout, including the number of air returns and such. Your system needs to have enough air returns to maintain the airflow. If it doesn't, your HVAC tech may recommend that you have more added.
