Easy Step-By-Step Process of Duct Cleaning


STEP #1: Start by removing the screws from the air duct covers using a screwdriver or power drill.

STEP #2: Cover the supply vents with paper towels.

STEP #3: Set the thermostat to the "on Fan" position. It helps in moving the dust particles that you are losing while cleaning.  Never forget to switch off the heat and cool mode.

STEP #4: Lose the dust in air ducts using your brush. Take the brush and start cleaning the dust or collected debris. It helps in breaking up any dust that is plunged to the insides of the channels.

STEP #5: Next, clean the supply registers/grills. Switch on the vacuum and point the hose near the register and pull it up. The hose will suck out the debris which is moved forward by the fan. Then, proceed to sweep inside the register's piping as far in as the attachment can reach. With the brush, loosen up any accumulated dust in the register.

STEP #6: Wipe the interior clean. Use a piece of cloth to reach down into the duct as far as you can and wipe clean.

STEP #7: Now wipe out the return registers.

STEP #8: Disconnect the fan and furnace. Disconnect the thermostat because to ensure you completely turn off the power of the whole unit.

STEP #9: Clean out the compartment of the blower and exchange air boot. By switching the power off, you can remove the panels on the front of the furnace and access the blower compartment and the return air boot. Use the vacuum to clean this area.

STEP #10: Relocate the furnace filter. Buy a good filter that will reduce the dust in your air ducts. If a filter is not clean, it limits the flow of air to the fan that makes the motor heat up, and also reduces its life span.
