Removing Vent Blockage Safely Will Save Your HVAC System

Your comfort is important. Without it, you will have a hard time relaxing, focusing or even just enjoying the company of friends. When your comfort has been compromised because of insufficient heating or cooling, vent blockage may be to blame.

  • Clogs in duct work can make individual rooms – or even your entire home – uncomfortably cold in the winter and hot in the summer. But you can check your own system for vent blockage and remedy it yourself by following a few simple steps.
  • Start by turning on your system and checking each individual vent for air flow. If only one or two vents aren’t blowing, then it’s likely that there is a blockage somewhere close to them. If, on the other hand, none seem to be blowing effectively, then the issue may be with the furnace filter itself.
  • If the filter is not clogged or has been changed recently but air still doesn’t seem to flow, you may have a block further down the line. Find it by inspecting more thoroughly each vent behind the grate and down into the ducts.
  • If you are still having trouble with air flow at this point, then it’s time to check the duct work itself. Make sure all seams are sealed and that no duct tape or insulation is in the duct. If you find weaknesses, now is the time to fix them.
  • Finally, if there is still an issue, check the butterfly valves leading to each room. If they are opened, the valve handle will run parallel to the duct. It will be perpendicular if it is not.

If, after following all of these steps, you are still unable to feel sufficient air flow from your vents, there is probably blockage somewhere internally. Your HVAC specialist can help you remove this so that your family can rest comfortably once more. That is, of course, unless your furnace itself is about to bite the dust. In which case, a replacement furnace may be in order.
