Duct cleaning brings an improvement to your home and to the air you breathe. When you clean your duct, you are increasing its lifespan because the dirt causes it to overwork its parts and it can tear apart. With a clean duct, you also get to breathe clean air and this is an important improvement for people with allergies. 

Cleaning your air duct is not a challenging process, especially if you have the knowledge and experience. However, before duct cleaning, it is important to ensure that you have the right tools, and you know where each part of the duct is placed and how you can return it after the process.

What you need to have before air duct cleaning services begin

1. A furnace filter. Ensure you buy a new furnace filter before starting the operation because you will need it at the end.

2. Vacuum. When buying one, go for the heavier duty unit. It does a better job than the typical household type of a vacuum.

3. Screw drivers

4. Paper towels

Steps to follow when doing cleaning

Cover up all your supply registers

Before you start the process, use the paper towels to cover all the supply registers in all the rooms the duct supplies clean air to. This is important so that you do not spread the dust you are cleaning from the duct from being deposited in the rooms. You do this by lifting the register and wrapping the paper register on top of it.

Switch on the fan

Remember you are loosening the dust in the duct, and it could easily be deposited to other places. Turning the fan on helps to move the dust that you are cleaning away as you are continuing with the duct cleaning process. Ensure the thermostat fan is at “fan on” but the heating and cooling system is off. You have the option of installing a new thermostat if your duct does not have the fan only option.

Inspect your filter

The dust you are loosening as you clean up can sometimes be pulled in the fan motor. To ensure that this does not happen, you need to that your old furnace filter is in place.

Make the dust in the ducts loose

Use a brush handle to make loose the dust in the duct loose for easy duct cleaning. You can use a longer brush stick to loosen the areas that are hard to each. This will make it easier for the vacuum to take in all that dust.

Ensure your supply registers are clean

After making the dust loose, it becomes easier to sweep it out in your supply registers. Ensure your vacuum is running so that it takes all the dust. Place the end of the hose near the register and lift the register.

The fan is pushing dust through the register, and placing the hose at the end of it will help you catch all the dust. If you notice any dust that is build up in the register, you can use your brush to loosen it. Also, ensure you remove deposits of the paper towels as you clean the supply registers.

Clean your return air registers

Screws hold the return air registers so you have to use a screwdriver and remove them. Brush and remove any dust that is held onto them to ensure that they are sparkling.

Switch off the fan and furnace

When switching off the furnace, do not just shut off the thermostat. Turning off the thermostat does not turn off the power to the unit. You should instead switch the fan and furnace off at the thermostat through the service switch or the breaker panel.

Clean the blower compartment and return the air boot

Before removing the panels on the front of the furnace, ensure that the power is off. Now you can have good access of the blower compartment and the return air boot. Use a vacuum to remove any air duct in these two areas.

Install a new furnace filter

This will lower the chances of dust build-up in your home. When your filter is dirty, there will be a restriction of airflow to the fan, which will affect the working of the duct system. The number of your times you should change your filter will depend on some factors like the location of your home and where you have pets.
