How Often Should Air Conditioning Ducts Be Cleaned?

How often should air conditioning ducts be cleaned? To arrive at a proper decision, you must conduct a visual inspection of your air ducts to be absolutely sure. Alternatively, you can let an HVAC repair professional do it for you. However, the timing for this clean-up depends on the region you live in, the climate, and how often you use your HVAC system.

How Often Should Air Conditioning Ducts Be Cleaned?

According to air conditioning unit repair experts, homeowners should have their air conditioning ducts cleaned every three to five years.  This is the industry standard, but there are instances where you have to do a clean-up more often. The right time for a duct clean-up depends on several factors, such as:

Musty Odour

You suspect that mould has developed inside the air ducts. Mould is recognisable by its musty odour. If you’ve noticed this smell inside your home for some time, it’s probably time to have your ducts cleaned.

You see a visible “poof” of dust released from the supply registers. If you see a cloud of dust when air is expelled from the ducts, it’s a sign that the air ducts need a clean-up. Additionally, if there’s black debris around the air vent register, these are usually signs that your air ducts need cleaning. You can also request your AC technician to look inside the system when changing the air filter. As a case in point, extensive dust build-up in the area indicates they need cleaning.


Do you hear buzzing or scratching sounds coming from inside your ductwork? These sounds indicate that there are unwanted guests inside the air ducts. Pests inside the AC ducts are a clear sign that you should prompt an air duct cleaning by your local air conditioning expert.

In Conclusion

Fortunately, you don’t need to clean the air ducts often to ensure the safe and proper running of your home’s heating and cooling systems. Scheduling an appointment every three to five years is enough to ensure your ducts aren’t actively damaging the health of those inside your home.
