Check every component of the system, including the registers, the plenums, the blower motor and the evaporator coil. Here are some steps to take:</p><ul><li>Look for dust or particles.</li><li>Make sure there are no rips or tears in the fiberglass if your ducts include fiberglass board, flexduct, or metal pipes lined with fiberglass.</li><li>Check for any signs of mold. Mold should be cleaned from metal pipes, and fiberglass material that had mold should be replaced.</li><li>Shine a flashlight on the evaporator coil. You should see the light shine through to the other side if the coil is clean.</li><li>If the air duct cleaner had to make any access openings, make sure they are proper sealed.</li><li>Test that your HVAC system works after the cleaning (in both heating and cooling modes, if you have both).</li><li>Ask the air duct cleaning company if each component on your list has been cleaned, and ask for explanations if they have not.</li></ul></div>
