Warranty & repair

• Can I still claim warranty?

  Manufacturer's warranty
  Many of our products come with a manufacturer's warranty. This means that during the warranty period, the manufacturer will repair or replace your item in case of a defect, unless you have caused the failure yourself. You can usually activate the manufacturer's warranty by registering the product online via the manufacturer's website, or by accepting the relevant terms and conditions. The manufacturer will determine whether the resolution of the complaint is covered by the warranty. 

  Statutory warranty
  Is there no manufacturer's warranty applicable? Then there is still the statutory warranty. This warranty means that your purchased item must live up to what was promised and what you could reasonably expect. Is something still wrong? Then we will do everything we can to offer you a good solution. Think, for example, of repairs, revision or maintenance work. 

  Warranty conditions
  

  The warranty period begins from the date of purchase. Warranty is valid only if the product or service was installed in accordance with the prescribed guidelines and configurations.

• Am I entitled to a subsidy if I buy a new MVHR system?

  It is possible to claim a subsidy from the government. However, this is often accompanied by other energy-saving modifications to the home. More information on this can be found on the RVO website.

• The fan is making noise, what are the possible causes and how can I fix it?

  There are several possible causes for extra noise coming from a ventilation unit. Below are some common causes and possible solutions:

  • Dirty air filters: If the air filters in your MVHR ventilation unit are clogged or dirty, this can cause a reduction in airflow and an increase in noise levels. Check the filters and replace if necessary.
  • Incorrect installation: An incorrect installation of the ventilation unit can cause vibration and noise. Ensure that the unit is installed correctly and that all connections are tightened securely.
  • Air duct problems: Air ducts run throughout the house and can cause echoes and noise. If there are problems with the ducts, such as leaks or blockages, this can also cause abnormal noise. Have the ducts cleaned, inspected or repaired if necessary. Make sure you use the correct ventilation ducts and add silencers.
  • Fan motor problems: If the fan motor is not working properly, it may cause abnormal noise. Have a qualified technician check the motor and replace it if necessary. If your unit is still under warranty, we advise you to contact the installer or contractor first. 
  • Age of the unit: After +/-15 years it may be time to replace the unit completely. You may find that the unit is struggling to operate at higher settings and energy costs are increasing. Newer technologies make the units quieter and more energy efficient.

  A completely silent ventilation system is not possible, either the motor of the unit itself or the air flow through the ducts will generate noise. However, we recommend regular maintenance to keep the unit running optimally and to avoid unnecessary noise.

• My MVHR system makes a bubbling noise. What could I do?

  It is possible that the MVHR system hose is dry. A simple solution is to fill the hose with water and add some oil to prevent evaporation. If this does not solve the problem, we recommend that you have the system checked by a technician.

• Any leak? Tips for dealing with a leaking ventilation unit

  If your ventilation unit is leaking, this could indicate a problem with the unit itself. This unit removes humid air from the bathroom, kitchen and toilet. If the ventilation box is not working properly, the moist air can become trapped in the ventilation ducts. This can cause the moisture in the air to condense and enter the house through the vents, with all its consequences.

  The most common cause of a leaky ventilation unit is a clogged or blocked exhaust or condensation drain. Check these and clean them if necessary.

  It is also important to have your ventilation system serviced and cleaned regularly. We recommend that you book a service every two years to clean and inspect the unit. To prevent leaks in your ventilation system, it is also important to have the installation done by a professional.

• What to do if you have a smelly mechanical ventilation system?

  If you suffer from a smelly mechanical ventilation system, there are several steps you can take to tackle the problem:

  • Check the installation: Poor installations can cause bad smells. To ensure that the installation has been done correctly and that the ventilation system is working optimally, we recommend having the installation done by a professional technician. They will ensure that all components are fitted correctly and that the valves are correctly adjusted.
  • Maintenance: Accumulation of dirt and dust in the ventilation system can lead to the growth of bacteria and mould, which can cause unpleasant odours. Regular maintenance is important to keep the system working properly and to prevent odour problems. On average, a ventilation system should be serviced every 2 years. We also recommend a full service every 7-8 years.
  • Clean the ventilation ducts: The cause of the odour may be in the ventilation ducts. Cleaning these ducts may solve the problem. We recommend that you have this done by a professional. If you live in an apartment block and notice that the ventilation system smells, it is important to contact the manager or the owners' association. We recommend that you have the ducts cleaned and possibly disinfected every 7-8 years.
  • Replace the unit on time: An outdated ventilation system can cause odour problems. It is important to replace the unit on time to avoid problems.

  If, despite these tips, you still have a smelly ventilation system, it is best to consult a professional to diagnose and fix the problem.

• Draughts in your home?

  Do you have draughts in your home? You may be tempted to close the vents and grilles, but this is not a good solution. Closing the grilles prevents the ventilation system from working properly and can create an unhealthy indoor climate. It is better to tackle the cause of the draught.

  Possible causes and solutions:

  • The ventilation system is not properly balanced. This can lead to too much air being exhausted, creating a negative pressure in the house and causing draughts through cracks and seams.
    
    • Solution: Contact a professional technician to balance the system. They can ensure that enough air is being extracted and supplied to prevent draughts.
  • The grilles and valves are blocked or dirty. This can result in insufficient air being exhausted, creating overpressure and draughts.
    
    • Solution: Clean the grilles and ensure that sufficient air can pass through them. If the grilles are very dirty, consider replacing them. Note: If the original settings are changed, the ventilation system may become unbalanced.
  • The temperature in the house is unevenly distributed. This can cause air currents that are perceived as draughts.
    
    • Solution: Check that the radiators are working properly and that there is enough air coming out of the grilles. Ensure that there is no furniture in front of the grilles that could obstruct the airflow and move the grilles to a higher position, preferably above the radiators.

  If you have followed these steps and are still experiencing draughts in your home, it may be advisable to consult a professional to diagnose and rectify the problem. Have your ventilation system checked and maintained. A properly functioning ventilation system can help reduce draught problems.
