Regular cleaning and maintenance of HVAC ducts at home has several benefits, the most important being it gives you cleaner air that’s good for your health. All the trapped dust, dirt, and other harsh elements in your air ducts leave your health at risk.

It’s ideal to hire the services of a professional for your air duct cleaning needs in Nashville, Fort Lauderdale, or anywhere else in the country. If you choose to DIY-clean your air ducts and vents, on the other han d, you need the right tools and know-how to get the job done. This is advisable only if you have the skillset, though. You wouldn’t want to make the situation worse that you’ll end up spending more (on repairs or replacement) than saving up.

Before getting started, you need to understand that cleaning ducts and vents require special equipment. It is important to use the proper tools to get the job done right. For this chore, you will need the following tools and equipment: a vacuum, brush, screwdriver or hex driver, duct tape, and furnace filter.

DIY-Clean Your Air Ducts at Home

1. Cover the supply registers.

Supply registers are where heated air passes through to get to the rooms. You don’t want dust and dirt to get through to the other rooms as you clean. Cover it up with duct tape first before getting to work.

2. Turn on the fan.

Turning the fan on will help loosen and carry the dust and dirt through the ductwork. Just make sure you turn off the heat supply beforehand.

3. Check the filters and make sure they are secure.

Make sure the furnace filter is in its proper place. It helps keep debris from being sucked by the fan motor. If any debris gets into the fan motor, it could damage it which could lead to you spending more on repairs.

4. Brush the dust away from the ductwork.

Take your brush and tap on the ductwork to loosen dirt and debris. Then carefully brush and wipe the dirt and dust off the ductwork.

5. Turn off the power to the furnace.

After leaving the fan on for a few minutes, you must turn it off before you get into any heavy-duty cleaning. This helps keep you safe as it is risky to access the main ducts with the system still running.

6. Vacuum the supply registers.

Remove the sealant tape carefully and start vacuuming dirt as it is released. Use the vacuum’s hose to get to the hard-to-reach spots inside the ductwork. Clean thoroughly and leave no spot untouched.

7. Brush the remaining dust off the registers.

Take your brush again and scrub away any remaining dust, mold, and mildew inside the vent system. Use a clean cloth to wipe as far as you can reach into the ductwork. Apply sanitizer to all registers.

8. Clean the blower compartment.

With the power turned off, you may now access the return boot and blower compartment. You may use your vacuum cleaner to sweep through this area but for a more thorough cleaning, you may take out the blower and furnace fan. Take them apart and clean each component only if you know how to put it back together.

9. Replace the furnace filter.

Take out the old filter and dispose of it. Replace with a brand new one. It is recommended that a furnace filter be replaced every month to keep the system at optimal performance.

10. Take out the coverings and test the system.

Lastly, clean up and remove all duct tapes from the coverings on the registries and your furniture. Turn the system on and test on different settings to ensure things are working properly.

If you encounter difficulties and challenges in the middle of cleaning the vent, it is best to get the help of a professional to avoid doing further damage to the system. After all, the main reason why you’re DIY-ing your cleaning is to save money and not spend more on repairs.
