If you are looking to clean your home’s air ducts yourself, this DIY duct cleaning guide is the right option for you. Of course, we generally recommend that you get the help of experts and professionals for this task; they can check whether your air vents need cleaning or not. In general, some people tend to undertake the process of cleaning the air vents themselves. If you are one of these people or are concerned about the cost of cleaning air vents, follow the DIY duct cleaning steps and recommendations below carefully.

What do ducts do?

Home ductwork is a system of pipes that runs throughout the home to transport conditioned air from the HVAC system. Also, sometimes ducts for absorbing outside air and transferring air from inside to outside are used as exhaust. Ducts are usually round and made of fiberglass, flexible plastic or metal. They pass through the walls and ceilings of the house, so the only places where ductwork is likely to be seen are exposed areas such as attics, basements, and any ducts that lead outside the home. In older homes, the metal ducts could be wrapped in asbestos, these channels should not be cleaned because it may cause the asbestos to become airborne and enter the home.

If your home was built before 1979 and your plumbing hasn’t been replaced, you should have a professional inspect the ductwork for asbestos.

What ducts do?

  • There are two types of channels: return and supply

Return ducts, remove air from the room, and return it to the HVAC system. Supply ducts carry conditioned air from the HVAC system to the room.

In the first step, you should find the duct of the supply channel and start cleaning it. There is an easy way to find the supply duct: place a tissue over the valve; if the tissue sticks, it is the return duct. Otherwise, it is the supply duct.

When is duct cleaning necessary?

Dirt, dust, and other types of debris can collect inside your home’s ducts and reduce indoor air quality. The problem is not that dust is circulating in your air, but the problem is that too much debris in the duct is interfering with airflow and the efficiency of the HVAC system. Dirty air ducts force the heating and cooling system to work harder, use more energy, and be less efficient. So you might think that it makes perfect sense to clean your home’s air ducts regularly, but it’s not.

When is duct cleaning necessary?

We recommend that you do not need to clean the air ducts yourself if the following conditions exist:

  • The ductwork is properly sealed
  • Often, the filters are changed according to the manufacturer’s recommendations
  • Floor registers should be vacuumed once every six months to prevent dust accumulation.

In general, duct cleaning is necessary under the following conditions:

  • There is noticeable deterioration of sealants and tape adhered to ductwork and/or those that weren’t properly sealed in the first place
  • Renovation of the house that has created significant dust or needs to add or replace ductwork
  • There are extensive damage from pests and animal nests
  • Substantial mold growth is present
  • Recommended maintenance is not performed.
