Improving indoor air quality: why it's time to replace your mechanical ventilation unit

Mechanical ventilation is essential for a healthy indoor climate. A mechanical ventilation box is the heart of the ventilation system, removing polluted air and supplying fresh outside air. It is important to maintain the unit regularly and replace it when necessary. In this blog we will discuss why it is important to replace a mechanical ventilation box on time and the benefits of doing so.


When should a mechanical ventilation box be replaced?

A mechanical ventilation box has a life span of approximately 15 years. After this period, the risk of malfunction and breakdown increases and the box may become less efficient.

However, if you notice that the ventilation box is malfunctioning more often or making a lot of noise, this could be a sign that it needs to be replaced. Also, if you are experiencing unpleasant odours or dampness in your home, a new ventilation box can help improve the indoor climate.

What are the benefits of replacing a mechanical ventilation box?

1.      Improved air quality

If the ventilation box is not working properly or is outdated, it can lead to a build-up of polluted air in the home. This can lead to health problems such as allergies, asthma and other respiratory diseases. Replacing the ventilation box on time will improve air quality and prevent health problems.

2.      More energy-efficient

Older ventilation boxes are prone to malfunctions or defects. In addition, these units often have low efficiency, requiring more energy to operate the system. Replacing the unit with a more energy-efficient model can save on energy bills and reduce environmental impact.

3.      Lower noise levels

New mechanical ventilation units are often quieter than older models. This is good for the home as it means the noise level is lower. This can also be beneficial when it comes to quality of sleep.

4.      More user friendly

New mechanical ventilation boxes are often easier to use than older models. For example, they can be controlled remotely and have more adjustment options. This makes it easier for you to tailor the box to your personal needs.


A good mechanical ventilation box is essential for a healthy indoor environment. Regular maintenance and, if necessary, replacement of the ventilation box will ensure that the air quality in your home remains optimal and prevent health problems. A new air handling unit is more energy efficient, quieter and easier to use than older models. It is therefore wise to invest in a new mechanical ventilation box in good time. Always get advice from a professional and make sure it is installed correctly. This way you can enjoy a healthy indoor climate and a comfortable home.
