How often should you clean your ventilation systems:  

Generally, the average period of getting your ventilation system cleaned by a professional is 3 to 5 years; however, you have to inspect it by yourself every week, which also depends on several factors.   

What are the different factors that tell us our ventilation system needs cleaning: 

Let us first discuss different factors that tell us when our ventilation systems need cleaning. You should be well aware of factors that will make your life more comfortable and healthier. It will also save you from wasting a lot of money. 

Type of ventilation systems:    

Natural ventilation systems:   

Natural ventilation is one of the best sources of fresh air. It works through windows, vents, and other open areas that allow air exchange.   

They require regular cleaning of windows, vents and other open areas, as windows and vents are always in contact with dust and pollutants.  

Automated fans:   

This type of ventilation system requires a weekly inspection.   


Exhausts are another ventilation system commonly found in bathrooms and toilets.     

It would be best if you inspect exhaust fans after every week.   

Supply Ventilation System:  

You should check supply ventilators after every 3 to 6 months for better functioning.   

Location of the place and usage: Ventilation cleaning also depends on the site of the building and its use. The areas surrounding dust and pollutants require more frequent ventilation cleaning services than the rest.  

 Similarly, if you use air conditioners and ventilation regularly, you need ventilation cleaning more often.   

Health concerns: if someone is allergic to dust in your house or you have asthma patient or other respiratory disorders, you need ventilation cleaning regularly.    

Warning Signs that tell us how often we should clean ventilation systems:    

Here are some warning signs that you should closely look at:  

A foul odour coming from the ducts:  

A strong odour indicates some junk in the ventilation system, and you must clean it. If you smell anything foul in your house but can’t place where it’s coming from, it can be from the air duct system.   

To confirm these suspicions, you must approach each air register closely and thoroughly sniff them. A technician can also check the air ducts for anything causing the odour.   

The dust has blocked the vents and ducts:  

If you find a puff of dust when the HVAC system turns on, it shows that the air ducts are dirty.   

Usually, when you turn on the heating and cooling system, no visible dust or debris is released. Visible dust, hence, clearly indicates dusty air registers.   

Inconsistent airflow in the home:  

Inconsistent airflow in your bedroom, bathroom, living room or even kitchen is the quickest sign that your air ducts need cleaning.   

Vents deliver consistent airflow. If this isn’t the case, have a professional check around every vent.   

Increase in energy bills:  

Your heating and cooling costs should remain consistent throughout the year, regardless of the season. If you see an increase in your expenses, it might be because of dirty vents. 

If your furnace and air conditioner are dirty, then it will require more energy to maintain the set temperatures. Increased bills are a direct result of more energy usage.   

The ductwork is making strange and unexpected noises:  

You undoubtedly are familiar with the sound your home’s HVAC system makes when operating. If you observe strange noise, it can be because of dirt in your air ducts.  



Ventilation cleaning is essential for a clean and healthy environment. Most households know how crucial duct cleaning is, and It’s necessary to have a cleaning schedule. Regular maintenance and cleaning mentioned above help ventilation systems function more effectively and last longer to make a clean and healthy indoor environment.   

However, professional technicians can only resolve some technical issues. Call a qualified technician if you see any of the signs mentioned above.
