Frequently asked questions

  • Benefits of MVHR ventilation system maintenance with probiotics

    Super-bacteria are a growing public health problem. They are resistant to antibiotics and disinfectants. What's more, they return in greater numbers after cleaning with chemicals. With probiotics, however, they can be effectively combated. In this way, they make an important contribution to the maintenance of MVHR units and help to maintain a healthy indoor environment. But maintenance is more than just cleaning the unit. It is also important to check all the mechanical components of the ventilation system.

    Not sure if you have an MVHR unit? Read our blog for more information: Choosing the right maintenance? Here's how to do it!

  • How often should an MVHR-unit be cleaned?

    • Twice a year: replace filters. Easy to do yourself.
    • Annually: Basic Maintenance
    • Every two years: Extended Maintenance
    • After 7 years: MVHR-ventilation duct cleaning
  • MVHR- ventilation maintenance cost

    At Intovent, we like to communicate clearly. Below is an overview of exactly what we have to offer. You can choose either a one-off payment or a subscription. A subscription has the advantage of low fixed costs and still ensures an optimally functioning ventilation system, while you benefit from priority when scheduling. Read more in our blog.

    Prices include VAT and call-out charges.

  • Good to know when ordering an MVHR maintenance service

    When you place an order, we will contact you within two working days. Based on your postcode, we will schedule a technician to carry out an expert ventilation service. The duration of the work depends on the type of service required. It is important to change the filters on your MVHR unit at least once every six months. If you order filters with a maintenance, they will be sent in advance.

    Our services are suitable for standard homes (max. 12 valves). Do you have a ceiling higher than 3 metres, or any other special features? Then there is a chance that the ventilation maintenance cannot be carried out or is difficult. In this case, please contact us.

    Please note: This service is not available for decentralised MVHR-units.

  • What should I know about the maintenance subscription?

    Do you have an MV or MVHR maintenance subscription with Intovent? Then we will schedule a maintenance visit. The service/maintenance subscription takes effect after Intovent has carried out an initial service and the unit has been accepted for the service/maintenance subscription. If the unit is accepted, we will immediately carry out the maintenance as part of the subscription. The technician will check whether the device can be serviced on the basis of:

    • Safety of installation and accessibility
    • Technical condition
    • No maintenance arrears

    Intovent comes for a maintenance service every 2 years. Depending on the subscription you choose, the duct cleaning will take place on the 1st or 2nd visit. A subscription offers extra peace of mind and you will also be notified when it is time for your next service. Is your ventilation system not working properly? A malfunction results in reduced or even no ventilation. If you have a subscription with Intovent, there are no call-out charges in the event of a fault. Troubleshooting is not included and we will charge the hourly rate in effect at the time. Materials will be charged at the applicable rate.

    You take out a maintenance subscription for a minimum of 24 months. After that you can cancel it on a monthly basis. Are you moving or do you want to stop the maintenance earlier? Contact us for options. Additional costs may apply.

What are probiotic cleansers?

In soil, water, air and the human body: microorganisms are everywhere. There are billions of them, and they have only one goal: to survive. Fortunately, most of them are good for us. For example, they provide digestion, compost or food such as wine and cheese. A small group of microorganisms are harmful to humans, animals and the environment because they cause disease and spoil food. These pathogens are usually controlled with chemical detergents, but superbugs are becoming increasingly resistant to them. Fortunately, there is an alternative: probiotics. Probiotic cleaning products have been formulated with bacteria that naturally fight pathogens. A natural solution to a natural problem.


Good for people, animals and the environment

Probiotics are extremely effective in neutralising superbugs. Probiotic cleaners are therefore very suitable for cleaning MVHR units. Odour molecules are absorbed, preventing odours. Probiotic cleaners are also safer to use than chemical cleaners. They are also useful after use, as they help to purify waste water. In short, a super result against super bacteria.


Replacing an MVHR

Ventilation maintenance optimises the life of your system. However, the fact is that every ventilation system needs to be replaced at some point. Do you have an MVHR system that is 15 years old or older? Have you noticed that air quality is deteriorating, energy consumption is increasing and/or the system is making more noise? Then it's time to replace your air handling system. Want to know more? Then read more on ‘Replacing a ventilation system’.

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.
