How To Adjust Your Home's Airflow

Posted on: 17 February 2015

If you find that when you turn on your air conditioner, you don't feel much air coming through the vents, you probably need to adjust the airflow. Even if the AC unit itself is working and the thermostat is set to the right temperature, you still might not feel as cold as you want to. This is because you need that airflow coming through the vents. Here are some tips for adjusting your home's airflow.

Adjust the Ducts

The first way to adjust your home's airflow is by adjusting the ducts. Start by finding the heating and cooling ducts. They will either be in your basement, attic, or crawlspace. A flashlight will help you to look in these areas to find the ducts, especially if you need to go through your crawlspaces. There will be small levers at the ducts. See if these levers are perpendicular or parallel to the ductwork.

If they are perpendicular, the damper is closed and that explains why you are not getting proper air flow. If they are parallel, the damper should be open. If they are perpendicular, try adjusting the level to allow more air to flow through that duct. Adjust just one at a time, then turn on your air conditioning to see if it makes a difference. Make sure you mark the setting of each one when you are happy with how it is adjusted.

Adjust the Registers

The next thing you can try is adjusting the registers. In each room, there will be a register for hot or cold air to come through. These will either be on the walls, floors, or ceiling. Once you find them, use the level to adjust the space where air can flow through. If you have an older home, the registers might not have a lever and will require you to pull the register out and manually open the vent. After you have opened the registers, wait a couple days before adjusting them in the next room. This is because it will change the dynamic of the airflow each time they are adjusted.

Add Airflow Manually

If the previous tips are still not working to adjust your home's airflow, you may need to do it manually. You can do this by using another air source in addition to the air conditioning unit. With the AC on, also turn on a fan in that room. Even with minimal air flow through the actual AC unit, the other source of air will cause more airflow in the room, and will also reduce your energy bill. Make a habit of turning on a fan at the same time as your AC, and you will be able to keep the thermostat lower.
