Maintenance of a ventilation system

Why maintaining a ventilation system is necessary

A ventilation system has a long life and works in the background without being noticed. This may give the impression that a ventilation system always works effortlessly, but this is not true: a ventilation system also needs attention. A poorly maintained system will work less and less well and make more and more noise. Polluted air cannot be completely removed and energy consumption increases. In addition, polluted air is blown into the house through the supply ducts. Maintenance helps keep the ventilation system healthy and extends its life. It also keeps your indoor air healthy.


Was your new home delivered with a ventilation system, or have you always had one in your home and can't remember the last time it was serviced? Then it's time to schedule a maintenance session! Our experts will work with you to decide what's best for your unit.

When should I have my ventilation system serviced?

On average, a ventilation system should be serviced every 2 years, although this will depend on the brand and age of the system. It is also advisable to have a full service, including cleaning and possibly disinfection of the air ducts, carried out every 7-8 years. With a service subscription, you are completely taken off the hook and everything is done for you automatically and on time. Is there a musty smell, dampness or even mould? Then it's time for immediate action. Contact us for a quick appointment.


How can I maintain my ventilation system myself?

You can easily remove surface dirt yourself. You can use a cloth and vacuum cleaner to keep the air valves and filters clean. In many cases, you won't need a technician to replace MVHR filters either. However, it is necessary to inspect and thoroughly clean the entire ventilation system, grilles and air ducts. Our service engineers have the right knowledge and the latest equipment to maintain the system properly. The result is a system that is not only spotless, but also recalibrated for optimum operation. Get ready for a fresh start.


What to do with a newly built house?

Your new home has been fitted with a ventilation system and you want to know what's needed? Continue reading to find out more about the right maintenance for your unit.

Proper ventilation in your home is necessary to create healthy indoor air quality. To ensure air quality, it is wise to opt for regular maintenance of your ventilation system. This will ensure that pollution from sources outside and inside the home is reduced. What you may not know is that in a new development, where there is a lot of construction going on, there are higher levels of dust in the air. If you have an MVHR unit, remember to check the filters monthly and replace them more often in the first year: are the filters dark grey or black? Then it's time to change them.

The extra dust in the air can also get into the unit and the ducts, which is why we recommend you do not wait and opt for regular maintenance by a professional. With a maintenance subscription, you never have to think about it again. Choosing the right maintenance package can have a positive effect on the lifespan and energy consumption of your system, as a bonus to an optimally functioning ventilation system.

  • What is important in ventilation?

    • Use the highest ventilation setting when cooking, showering or receiving visitors.
    • Never turn the ventilation off completely, except in an emergency.
    • Leave a gap of at least 1.5 cm under internal doors to allow for air circulation and ventilation. Take this into account when laying floor coverings.
    • Have the ventilation box or heat exchanger and air ducts cleaned regularly.
    • Keep internal door and/or window vents open and clean.

    Do you like to ventilate your home? Then keep the following points in mind: 

    • Open windows and doors against each other for at least 15 minutes.
    • Is the heating on? Turn it down as low as possible or off completely (if possible) while airing.
    • With any ventilation system, it is not recommended to leave windows open for long periods in winter. The house will cools down unnecessarily and energy will be wasted.

    Tip: also ventilate during or immediately after special activities, such as painting or a party. This is the quickest way to remove humidity, dust and harmful substances such as solvents.

  • Product with status delivery time upon request. What does this actually indicate?

    The item you are looking for has the status "Delivery time upon request". But what does that mean?

    It is not always possible for us to provide an exact delivery time. The market is currently experiencing a shortage of materials and this has resulted in longer than usual production and delivery times from our suppliers. This is a common challenge faced by many companies in today's market and it has affected the availability of certain products and parts that we need to fulfil orders. We apologise for any inconvenience this may cause.

    In addition, while most of the products in our range are available from stock, we also offer the possibility of ordering products that are not in our range. For these products we can only give a delivery lead time after request. In such cases you can contact our customer service for more information.

  • What can I do myself to maintain my ventilation system?

    You can easily clean the valves yourself by soaking them in soapy water and brushing them. There is also a foam ring behind the valve. You can replace this over time. 

    Note: It is important to remember which position the valves are in when they are removed. This will determine how much air can flow through the valve. Make sure that the opening of the valve is the same when you replace it. If necessary, you can use a marker to make some marks on the inside (depending on the type of valve).

  • When should I have my ventilation system replaced?

    A mechanical ventilation system has a service life of approximately 15 years. We recommend that it is replaced at the end of this period to ensure a properly functioning ventilation system. Want to get the most out of your ventilation system? Then make sure it is serviced on time. Have you noticed that the system is making more noise? Or are you experiencing condensation? Then it is wise to have your ventilation system checked by a professional.

  • Is it possible to have a mechanical ventilation system replaced by an MVHR system?

    In a mechanical ventilation system, only polluted air is mechanically extracted. With an MVHR system, air is both exhausted and supplied. Additional air ducts should be provided for this supply. These must be installed in the house. Are you considering replacing a mechanical ventilation system with a heat exchanger? If so, get in touch with one of our experts.

  • Why is it necessary to change the air filters, and how often should this be done?

    Bacteria and mould gradually build up in the filters. This causes a deterioration in the air exchange capacity. In addition, the ventilation system becomes noisier if the filters are not changed regularly.

    On average, it is recommended to change the air filters at least twice a year. If your region or neighbourhood has poor air quality, you may want to change the filters more frequently, for example if you live in an urban area with a lot of traffic. If you suffer from allergies or asthma, you may need to change the filters after only 2 months.

  • Can I vacuum or wash out the filters of my MVHR system myself?

    This is not recommended. The fibres may be damaged or lost, reducing the performance of the MVHR system. However, it may be a temporary solution for dirty filters. If you wish to wash air filters, do not use detergents! Our advice is and remains to replace the filters when they are dirty. This will keep the MVHR system working optimally.
