Air Duct Cleaning: The DIY Approach

Cleaning your home seems to be an ongoing task with no end in sight. As soon as you’re done cleaning, dust comes out of nowhere. And it’s not because you haven’t cleaned your home well, but because you missed cleaning the air ducts.

Air ducts accumulate dust, dirt, pollen, pet hair, and debris over time. These spread all over your home whenever you activate the HVAC system. Cleaning them regularly will ensure you and your family have clean, quality air in your home. 

DIY air duct cleaning isn’t as complex as you may think. Although it takes some time, it doesn’t require special gear.

So, how to clean air ducts DIY?

Cleaning the air ducts in your home is straightforward and doesn’t require special skills or equipment. In this article, we show you exactly how to do it step by step to get rid of the hidden debris in your home easily.

When Should You Clean Air Ducts DIY?

Cleaning the air ducts is essential for improving your home’s air quality. They collect dust, hair, and allergens, instantly spreading them into your home when you turn the system on. Moreover, they may develop mold or trap insects and pests like mice.

Cleaning air ducts DIY regularly helps prevent these manifestations, keeping your home safe and healthy.

So, when should you clean air ducts?

The general rules of air duct cleaning frequency are as follows:

• Twice a year – in spring and fall, before activating the seasonal HVAC systems.
• Once a year, if you or someone in your home has allergies and/or if you have pets.
• Every 3 to 5 years, if there aren’t specific situations or people with health issues in your home.
• When renovating your home or having major repairs.
• When buying a new home.
• When the ductwork is over 7 years old, and when you audit the system for leaks.

However, you should immediately clean air ducts if you notice a lot of dust after cleaning your home or if there’s an odor upon turning on the HVAC system. The same goes for extensive pest damage, pest/animal nests, or larger quantities of mold.

Deteriorated sealants or tape and/or improperly sealed ducts are another reason for immediate air duct cleaning.

DIY Air Duct Cleaning: Step-by-Step Guide

Cleaning the ductwork yourself isn’t challenging if you know what you’re doing. To save you time searching for the best air duct cleaning methods, we’ve compiled a list of all the steps you need to follow.

Never done it before?

No problem. We’ll walk you through each stage of the air duct cleaning process.

Remove the Registers

Remove the supply and return air registers (the vents from which the conditioned air comes into your home) using a screwdriver. If they have a screw-less design, twist them counterclockwise.

Once removed, cover them with rags or cloths, preventing the dirt accumulated on them from falling onto the floor and spreading throughout your home.

Turn On the Fan

Next, you need to turn the fan on and turn off the “heat/cool” mode. You can run the heat if you don’t have a standalone heating/cooling mode.

Having the fan on during the cleaning process helps dislodge dust and particles from the ductwork, and this helps you remove them much more easily.

Clean the Supply Registers

Clean the supply registers with the rags you have covered them with, or use a brush. Make sure you clean them thoroughly. If they’re very dirty, use a mild cleaning solution mixed with water to help break down grime.

Once cleaned, dry them, and reattach them.

Clean the Return Air Registers

Use a brush to loosen any dust and dirt that may have built up on the surface. Once loosened, vacuum-clean the dislodged dirt from the return air registers using a vacuum cleaner with a brush attachment.

Take your time to clean each register to remove all visible dust thoroughly. 

Turn Off the System

Turn off the HVAC system completely to prevent the fan or other settings from accidentally turning on while cleaning the ducts. Having the system turned off ensures your safety and allows for a more focused cleaning experience.

Loosen the Dust in the Ducts

Use your brush to clean the ducts effectively. Gently insert the brush into the ductwork, reaching as far as you can. Move it back and forth to loosen the dust and debris that may have accumulated on the inner walls of the ducts.

Vacuum-clean the Ducts

Attach a hose and a brush extension to your vacuum cleaner. Insert the hose into the ducts and move around to reach as many parts of the duct as possible. This will help you suction up the dust and debris you previously loosened with the brush.

Repeat the process with all ducts. Make sure you clean all accessible areas and vacuum all the debris you can.

Clean the Blower Compartment

The blower compartment is usually found near the furnace or air handler. Open it and check it for any dirt, dust, or debris.

Use a brush or a microfiber cloth to carefully clean the fan blades, motor, and surrounding surfaces. Clean as gently as possible to prevent damage to any components or wiring during the cleaning process.

Replace the Air Filter

In most systems, the air filter is usually near the blower or furnace. Once you locate it, carefully remove it and insert a new filter, following the manufacturer’s instructions.

The new filter must be compatible with your system and fit properly.

Turn On the System

Turn the HVAC system back on, adjust the thermostat to the desired temperature, and switch to a heating or cooling mode. Check the airflow to ensure it’s steady and consistent.

Let it work for 20 minutes to see if there are any unusual noises or issues. If everything works well, you’ll know you did a great job. Congrats!
