Steps on Cleaning your Air Ducts and Vents

1. Cover Supply Registers

The first step to cleaning your air ducts and vents is to cover the supply registers using paper towels or microfiber cloths. Your ducts are going to undergo a thorough cleaning, and it is only logical that you prevent the dust from going to other areas around the home. To cover the supply registers, simply lift the grills and cover using paper towels then replace them.

2. Turn on Fan

It is advisable that you turn on the fan just before you begin cleaning your ducts. This will loosen up the dust and ensure that it moves along, as you begin your cleaning. However, make sure the heat supply is switched off.

3. Clean Supply Registers

Now that dust and other elements have accumulated on your supply registers, it is only rational that you clean them. Depending on the magnitude of the debris, you may use a brush or vacuum cleaner to clean your supply registers. Simply lift the registers and literally sweep out the dust and debris. Use a long broom to sweep deep into the registers’ piping system.

4. Clean Return Air Registers

Unscrew the return air registers and sweep off any dust that might have accumulated inside the piping system. You will need a brush with a longer handle to access deeper areas inside the cavity.

5. Turn off power connected to the System

After leaving the fan running for a few minutes, it is recommended that you turn off the power connected to the system, as you get down to serious business. This is because you will need to access the main ducts and it is highly risky to do this when the system is running.

6. Unscrew Air Duct Covers

Air duct covers are often fastened using screws or other fasteners. Using a standard screwdriver, unscrew air duct covers and grills, to gain access to your ducts. Clean the grates using a cleaning cloth. If they are too dirty, then you should consider using soap and water

7. Vacuum Clean the Air Ducts

This is where the real work begins. Your vacuum cleaner should have a hose, long enough to reach the troublesome spots and corners. Vacuum clean your air ducts thoroughly, leaving no spot untouched. If possible, you should acquire a heavy-duty vacuum cleaner, considering that a conventional cleaner is not powerful enough for deep cleaning. Use your brush to remove molds and mildew inside the ductwork. Additionally, use your cleaning cloth to wipe the interior of the duct as far as you can reach.

8. Clean Blower Compartment

Considering that the power is off, you can now access the return air boot and the blower compartment by removing the panels on the front of the furnace. Majority of dust and dirt builds up around the furnace, leading to clogging. Use your vacuum cleaner to remove dirt and debris from the blower compartment. Take extra precautions when cleaning the furnace fan so as not to damage it.

9. Replace Furnace Filter

Clogging and buildup of dust will definitely damage your furnace filter. A malfunctioning filter will not only restrict airflow, but also reduce the lifespan of your air conditioner. After cleaning your air ducts and vents, always make a point to replacing your furnace filter. Consider calling a professional if you do not know how to change a furnace filter.

Conclusion

Cleaning air ducts and vents in your house can be effective if done correctly. However, when everything is done and dusted, your home will probably be in a big mess. Use your vacuum cleaner to cleanup your home and make use of the cleaning cloths to dust your furniture. If you are having trouble cleaning your air ducts, then you should consider enlisting the services of a professional cleaner.
