Your health is directly related to the indoor air quality around you. The presence of dust particles, irritants, pollen or mold spores in your air conditioning systems can be extremely dangerous to inhale.
Just like any other HVAC system, air ducts require regular maintenance to ensure maximum efficiency. Here a question arises: how to clean the air ducts?
As a general rule of thumb, the National Air Duct Cleaners Association (NADCA) recommends air duct cleaning every 3 to 5 years.
What is air duct cleaning?
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems.
Air ducts are passageways that transport cooled and heated air throughout your house. Just like any other HVAC system, air duct cleaning and regular maintenance ensure maximum efficiency. If not cleaned timely, the accumulated dust and dirt get filled with contaminants and air pollutants that can not only harm your indoor air quality but can also cause your HVAC system to work harder.
Consequently, this not only increases your energy bills, but can also significantly shorten the life expectancy of your system.
Your home’s cooling system will perform better with regular maintenance, and air duct cleaning to ensure the longevity of your entire HVAC system.
When to Clean The Air Ducts?
If you are uncertain about when to clean your air ducts and how often you should do it, here are some common signs of dirty air ducts which can cause duct problems in the long run.
Ducts clogged with dust and debris
In normal situations, air ducts do not expel visible dust or debris when the heating and cooling system is switched on, and the air starts to flow through the ducts. Therefore, if you see a visible presence of dust is probably a clear sign of dirty air ducts.
If you notice:
- Your home or commercial area seems dusty.
- Every surface is coated with dust immediately after cleaning the area.
- If you notice dust coming out of the vents every time the HVAC system kicks on.
These are signs of dirty ducts. You probably need to have your ducts cleaned.
Remove a vent cover filter and take a look at the ductwork. If the metal is covered in dust and you see dust and dirt both inside and outside your ducts most likely need to be cleaned.
Make sure you replace your HVAC system air filters frequently to prevent future dust buildups.
Ducts Infested with Insects
Even the cleanest homes can have dirt, dust, pet dander, and all sorts of harmful contaminants lingering in the air ducts. From time to time, mice, squirrels, rodents and insects can make their way into your air ducts. They leave behind all sorts of bacteria and droppings. This allows tiny faecal spores to sweep along the ducts. These spores can then make their way into your home and contaminate the quality of the air you breathe.
Keep in mind that a bacterial infestation might require more than air duct cleaning. If the issue is overlooked, it could lead to serious damage to the HVAC equipment as well as to the health. Moreover, an HVAC system that doesn’t work efficiently, leads to higher energy bills.
Frequently clogged filters
No doubt filters need to be changed periodically however, they shouldn’t be clogged after every few days of replacing them. If you have to change HVAC filters now and then this could be an indication of a deeper problem. This is a sign that you need to check on the air ducts.
Rising Energy Bills
Your heating and cooling costs should be relatively predictable from year to year. If you notice that your electricity bill has suddenly skyrocketed, dirty ductwork might be to blame.
With continuous use, the ductwork can accumulate with too much dirt that air can not flow freely and efficiently through your home’s HVAC system. Thus both your furnace and air conditioner are forced to work harder to maintain a comfortable indoor temperature. This causes higher utility bills for you and your family.
Unpleasant odor from ducts
Another evident sign of the presence of debris in your commercial or industrial HVAC duct system is the ducts emanating an unpleasant odor. It is a sign you should conduct serious ventilation system cleaning. It is best to consult an expert technician who can inspect the air ducts for anything that could be emitting a bad smell.
Strange and unusual noises in the ductwork
If you have lived in your home or owned a building or commercial area with an HVAC system installed, you know how the HVAC system sounds when it is operational. Your ductwork shouldn’t make a lot of noise while operating. If you hear anything more than the general motor sound, your ducts could be experiencing some problems.
Air that travels through the ductwork should deliver relatively consistent airflow from room to room. If you notice that a bathroom, bedroom, or other room in your home doesn’t receive the same level of airflow as other rooms, inconsistency could be the reason. Dirty air ducts, accumulation of debris in your air ducts, and any leaks you have in your ductwork ultimately decrease the efficiency and increase your energy bill.
All of this causes your system to have to work harder. Hiring an air duct technician to clean your ducts won’t only remove harmful contaminants, but can also rule out potential leaks.
How to Clean the Air Ducts?
Cleaning air ducts is an important aspect of maintaining a healthy indoor environment. While some people may choose to hire professionals for this task, others may prefer a DIY approach. Here’s a general guide for cleaning air ducts:

- Vacuum the Ducts:
- Use a vacuum cleaner with a hose attachment to suck up the loosened dirt and debris. Ensure the vacuum has a HEPA filter to trap fine particles.
- Clean the Registers:
- Wipe down the inside of the registers using a microfiber cloth. You can use a mild cleaning solution if necessary.
- Inspect for Mold or Mildew:
- If you notice any signs of mold or mildew, consider using a solution of water and vinegar (or a mold-killing solution recommended by professionals) to clean affected areas.
- Check for Duct Damage:
- Inspect the ducts for any signs of damage or leaks. Repair or replace damaged sections as needed.
- Replace Vent Covers:
- Once the ducts are clean, reinstall the vent covers securely.
- Turn on the HVAC System:
