Be Careful Blocking Off Supply Registers in Your Home

Posted by Kim Nemecek on Fri, Nov 01, 2013 @ 11:52 AM

We had a call recently from a homeowner who needed to replace his 12-year old furnace. He was not happy about it; he had expected to get more than 12 years out of his furnace.

Little did he know that closing the registers upstairs caused there to be insufficient airflow moving through his furnace. This caused some of the furnace components to get too hot, which led to their early failure. Thankfully he shared this with us so he would not have to replace another furnace before it’s time!

What is the correct thing to do?

  • Some adjustments can be made to the supply registers. If one room is warmer than another, adjusting the damper a bit can help both rooms feel more comfortable. To make sure you’re not causing an airflow problem, have a technician check the static pressure to make sure there is sufficient airflow through the system.
  • Have a home performance assessment to see if there is a reason one area of the home does not stay comfortable. We often find areas that can be sealed for an immediate improvement in comfort.
  • You can run a constant fan to help balance the temperatures in your home between rooms. This works especially well in the summer, as the movement of the air can feel drafty to some people in the winter.
  • Consider a zoning system. These systems install multiple thermostats in your home that allow your system to run separately in each zone as needed.
