Duct cleaning

Cleaning ventilation ducts requires regularity

To prevention is better than to cure. The same applies to duct cleaning. After all, the whole point of a ventilation system is to replace polluted air with clean air. As time goes by, more and more dust, mould and particles build up in the ducts. It is therefore necessary to have the ducts cleaned at least once every 7-8 years (mid-life). It is also advisable to have the ducts cleaned when a ventilation system is replaced.


When we come to clean the ducts in your home, it will take our technician about half an hour to an hour. This depends, among other things, on the type of mechanical ventilation system you have in your home. An MVHR (heat recovery ventilation) system has more ducts than a standard mechanical ventilation system. Once you have placed your order, we will contact you within two working days to arrange an appointment. Depending on your postcode area, our technician will be scheduled. Once our technician has cleaned the ducts, the system is immediately recalibrated. The house will also be left tidy, so you can enjoy a pleasant indoor climate straight away. Nice, isn't it?


Please note: our services and materials are designed for standard homes (maximum number of valves is 12). Is the ceiling higher than 3 metres or are there any other peculiarities? Our technician may not be able to carry out the service or may find it difficult. In this case, please contact us first.

Frequently asked questions

  • Why cleaning mechanical ventilation ducts?

    There are a few reasons why air duct cleaning is important:

    1. Over time, dust and dirt accumulate in the ventilation ducts and air filters. This impedes airflow, requiring the system to work harder to move the same amount of air. This can lead to excessive wear and tear on the fan, motor and other components. This increases the risk of early system failure.
    2. As pollution increases, the heat exchanger of a MVHR-system starts to perform worse. The ventilation system needs more and more energy to cool or heat. And yes, you will see that reflected on your energy bill.
    3. The more pollution, the more it affects air quality. A ventilation system can provide an ideal breeding ground for fungi and bacteria to grow and multiply. This increases the risk of unpleasant odours and health problems for occupants, such as respiratory infections. People with allergies usually notice quickly if the air quality is not right.
    4. The above conditions also have an indirect long-term effect: they negatively affect the lifespan of your ventilation system. In other words: the system wears out faster. How strong that effect is obviously depends on the degree of pollution.
  • Advantages of cleaning home ventilation ducts

    Cleaning ventilation ducts is important to prevent risks. It provides several immediate benefits:

    1. Topping the list, of course, is the health perspective. Cleaning ventilation ducts is important for good air quality.
    2. Improved energy efficiency. Whether mechanical ventilation or MVHR, the system can only function optimally if the ducts are clean. Cleaning ventilation ducts therefore has a direct effect on performance.
    3. Extending service life. As mentioned, the accumulation of dirt and dust comes at the expense of the life of the ventilation system. However, the reverse is also true: keeping the air ducts clean extends their lifespan and reduces the risk of malfunctions.
    4. Lower costs. With regular maintenance, you reduce the risk of expensive repairs and having to replace parts. If you maintain a ventilation system properly, you get the most out of its technical lifespan.
  • Cleaning your own ventilation ducts

    While it is theoretically possible to clean ventilation ducts yourself, in practice this is often disappointing. Depending on the size of the MVHR-system and the accessibility of the ducts, this quickly becomes a complex, time-consuming job. To avoid damaging the ventilation system, you need to know what you are doing. If you have neither experience nor the right tools, we recommend that you hire a ventilation specialist to do this.

  • Getting ventilation ducts cleaned

    Need your mechanical ventilation cleaned? Intovent's service technicians know all about this too. These specialists have the knowledge, experience and the right tools. They clean ventilation ducts on a daily basis. They work professionally, efficiently and cause minimum inconvenience. When they clean the ventilation ducts, dirt, dust, mould and bacteria are removed from the ducts and the components of the system. Think of the fan, heat exchanger and filters. They do this by using special tools and techniques, such as brushes, vacuum systems and compressed air. Note that system components are not cleaned during a duct cleaning, but they are cleaned during a maintenance service (All-in).

  • Cleaning ventilation ducts: how often?

    Rest assured: ventilation duct cleaning is a low-frequency maintenance job. Intovent recommends having it done once every 7 to 8 years. Tip: put it in your diary and you will be reminded. Want to know more about the frequency of maintenance work? Then read the blog article 'How often to have mechanical ventilation cleaned?'

    Cleaning air ducts is important, but cleaning a ventilation system requires more than just occasional ventilation duct cleaning. Want to know how exactly? Then read on about maintaining a ventilation system.

Why cleaning ventilation ducts is really necessary

The effect of dirty ventilation ducts may seem small, but it is not. Did you know that it can reduce the performance of a ventilation system by up to 30% within 5 years? The system will also make more noise and consume more energy. And then there is the health risk: dirt that is not removed remains in the house. In short, duct cleaning is essential.


Intovent's way of working

To clean air ducts, our service technicians have a powerful hoover connected to a flexible hose. At the end is a rotating brush that thoroughly brushes the inside of the ducts. All the dirt is loosened up and immediately removed by the hoover. Of course, the supply ducts and the installation itself are also thoroughly checked and cleaned.


Flexibility and Transparency: our General Terms and Conditions

To ensure that we provide the best possible service, we have some general conditions. One of these conditions is that, based on our technician's on-site assessment, we may decide to carry out more or less work than previously agreed. We do this in order to carry out our work in a professional and efficient manner and to ensure that the appliance and the ventilation system in the home continue to function properly.

  • If we decide to carry out more work than previously agreed, we will always inform you in advance of the additional work and its cost. We will only carry out the additional work if the customer agrees.
  • If we decide to carry out less work than previously agreed, we will also inform you of this decision and the reasons for it.

If the work cannot be carried out because, for example, incorrect information has been provided or the wrong service has been purchased, it is possible that we will not be able to carry out the work within the specified time. If this is the case, we will have to reschedule and charge you for the call-out costs incurred in accordance with our webshop rates. If we are unable to carry out all or part of the work due to circumstances beyond Intovent's control, we will not refund any amount already paid.
