How to Clean Your Air Conditioning Vents

One of the most important parts of owning an HVAC unit is making sure that the vents and air ducts in your house stay clean. Not only does cleaning them contribute to the longevity of your unit, but it keeps the air you breathe safer!

How Do I Know When to Clean My Home’s Air Ducts?

The National Air Duct Cleaners Association recommends getting your ducts cleaned every three to five years. This is because, over time, the ducts can accumulate billions of particles of dust, hair, spider webs, pollen, mold, and other allergens. If you suspect that mold exists in your air ducts, or you see a visible “poof” of dust leaving the vent when the air turns on, you’ll know it’s time for a cleaning!


Follow these steps to effectively clean your air ducts before summer:

  1. Disconnect the power that goes to your heating and air conditioning system.
  2. Unscrew the air vents or grilles from the wall. Use a cleaning brush with coarse bristles to thoroughly clean the grates. If they are too grimy to clean completely with a brush, submerge them in a sink or bucket full of soapy water and let them soak while you continue cleaning out the air duct.
  3. Now, vacuum the ducts thoroughly with a heavy duty vacuum. You may need to rent one of these from a local utility store. The standard vacuum isn’t usually powerful enough to clean deep into the recesses of the ducts, so you’ll want to make sure that the vacuum you use is not only powerful, but has a long hose that will reach far into the duct. Vacuuming is the most important step of cleaning your air ducts, because it removes mold, mildew, and other allergens that make your air unsafe to breathe.
  4. Lastly, you’ll want to tackle the covers and grilles in your ceiling. Remove, clean, and vacuum them using the same process you used for your wall vents. If they are particularly dusty, you may want to wear a face mask to protect your mouth and nose from falling debris.


When To Call A Professional

In some cases, you may want to hire a professional to come out and give your air ducts a deep cleaning. If you are re-entering a house that has been dormant or unkept for a while, or if you suspect that vermin or insects are infesting your home’s airways, contact your local professionals for advice.
