If you have rooms in your house that never get warm, you might think that you have a problem with your furnace. Unfortunately, this is an area that will likely not be fixed by calling for a furniture technician to come make repairs. Instead, your problem likely resides in your ducts. Understanding how duct dampers work can help you to make heating repairs on your own and get even, balanced heating throughout your home.
What Is A Duct Damper?
The air flowing from your furnace does not naturally push the same amount of air down every branch in your ductwork. Ducts that branch off closer to your furnace can draw more air than other ducts, and you may have smaller branches that don't funnel in as much air as larger branches. A damper is a revolving door in your ducts that you can use to adjust the amount of air that flows into the different branches of ductwork.
How To Adjust Dampers
Once you know what to do, adjusting dampers in your ductwork is not all that difficult. Follow these steps as you seek to balance the heating in your house:
1. Place a thermometer in each room of your house. After thirty minutes, note the temperature in each room. In a properly balanced system, all thermometers should give the same reading. If there are discrepancies, move to step 2.
2. Access your ducts in your attic or basement and find the dampers.
3. If a room was colder than other rooms in your house, open the damper to that room. A damper should have a handle on the outside of the duct. Turn the handle to the right or so that it is in line with the direction the ducts are running.
4. If a room was too hot, close the damper to that room by moving it so that it lies across your ducts.
5. You might have to continue making slight adjustments to dampers until you achieve the right flow of air into each room to yield the same temperature reading in each room.
Your thermostat will be located in just one room in your house, and simply adjusting the thermostat may not achieve the ideal temperature reading in each room of your house. Instead, you will need to make adjustments to the flow of air going to each room to make sure that you get balanced heating throughout your home. If you are sick of dealing with some rooms that are uncomfortably hot and others that are too cold, it's time to take adjusting dampers into your own hands.
