The efficiency of your HVAC system is reliant on several important factors, and airflow is one of the most significant. If your airflow is being blocked or slowed down in any way, it doesn't really matter how new and energy efficient your major appliances are. For example, even if you have the newest, most energy efficient furnace, it won't be using its maximum potential if the air is not freely flowing. This article explains some of the most common airflow issues and how to fix them.
Adjust Your Air Registers
Many people are surprised to find out how much more efficient their system can be if they simply adjust their registers. That is, if your air registers are not properly adjusted, your home's airflow will not be optimized. Homes do not heat totally evenly. A room on one side of your house could be significantly warmer than a room on the other side. If this is the case, partially close the register in the warmer room and open wide the register in the colder room. Also, rooms that are farther away from the actual furnace are going to receive less airflow. Even when your registers are closed, some air will probably seep into the room and warm it up. So, you just need to do a little bit of trial and error to test and figure out what the best settings are for optimum airflow in your home. Also, you usually will need to adjust your registers differently during the winter and summer.
Clean the Furnace Blower
Of course, adjusting your registers isn't going to solve all your problems. Another common problem is a dirty furnace blower. If the blower fan has dust and dirt buildup within the motor or on the fan blades, you should clean it. Before you clean your furnace cabinet, you need to make sure the power is turned off so there is no risk of it turning on while you are working on it.
Once it is safe to work on your furnace blower, all you need is a hose vacuum, which will enable you to sand off the fan blades and clear any dust in between the motor vents. You might also need to use a wet rag to wipe down some of the surfaces to get the last remnants of dust.
As you can see, neither of these jobs are difficult, but they can both help with long term functionality and efficiency of your heating system.
