Discover how to clean filters yourself, when professional maintenance is needed, and what the costs are. With local installers in your region.
A ventilation system runs day and night to remove stale air and supply fresh air. Without proper maintenance, dust, pollen and bacteria accumulate in filters and ducts. This not only reduces air quality, but also increases energy consumption and can cause malfunctions. Regular maintenance ensures that your system continues to work quietly, efficiently and healthily.
In Flanders, you mainly see type C systems (mechanical extraction) and type D systems (balanced ventilation with heat recovery). Type C extracts moist air via a central fan, while fresh air enters through vents. Type D has two fans: one for exhaust and one for supply, and a heat exchanger. Each type requires its own maintenance approach.
Unsure about your type? Discover which type of ventilation system you have and what maintenance it requires.
A large part of the maintenance can easily be done yourself. This way you keep costs low and your system in top condition:
Some tasks are too complex or risky for a DIYer. A certified technician performs an annual inspection, cleans the fan and checks the electronics. Especially with type D, professional maintenance is recommended: the HRV unit contains fine mechanics that need precise adjustment. In addition, a thorough duct cleaning every 3 to 5 years is really a job for a specialist. They have rotating brushes and powerful vacuums to clean the entire pipe system. Get advice from a local installer in your area.
The costs vary depending on the type of system and the scope of the work. For annual maintenance, including filter replacement and functional check, you can expect to pay an average of €100 to €250. A complete duct cleaning costs significantly more, depending on the length and accessibility. Request a tailor-made quote for a realistic price estimate.
For private homes in Flanders, there is no general legal maintenance obligation, unless specific EPB requirements apply for new construction or renovation. For companies, occupational health and safety standards or other regulations may apply. Regardless of the obligation: regular maintenance protects your health, lowers your energy bill and extends the lifespan of the installation. Moreover, most manufacturers require maintenance as a condition for warranty.
