Find a Pro to Check Your Home Furnace Ducts for Blockage

Blockages within home furnace ducts can reduce the effectiveness of your home heating system and lead to expensive repairs or replacements. For these reasons, it’s a wise idea to have your home furnace ducts inspected by an HVAC professional to ensure that no blockages exist.

Inspecting ducts for blockages isn’t a hard job. First, the technician will turn your thermostat off, and then remove the vent grate for inspection There, the technician will see whether any dust or loose dirt is present within the area. Your technician will also shine a flashlight and/or hand camera down into the duct to see if any blockage is visible.

If a blockage is discovered, a vacuum will likely be required to remove it. Blockages near the vent opening can be removed rather easily, however, blockages further down your duct system will require a specialized vacuum designed to reach the area with sufficient suction for debris removal.

Once the blockage is removed, your technician will see whether or not other blockages exist. One way to do this is to tie a plastic bag to the vent, turn the vent on and see how quickly it fills up. If it struggles to inflate, there’s another blockage in your system.

Common causes of duct blockages include pet dander, dirty air filters, children’s toys and pieces of insulation. All of these can build up over time to reduce airflow throughout your home, and most importantly, through your HVAC system. For this reason, it’s a good idea to have your ducts inspected every few years. Of course, if you notice a sudden or considerable drop in airflow, don’t delay. It takes just a few moments for a technician to inspect your ducts and it’s well worth every penny of the investment.
