How does requesting a ventilation quote work with you?

You fill in our form or call us. Within two days we schedule a site visit. Our installer inspects your home, discusses your wishes and draws up a detailed quote. Everything is without obligation.

Will I get a grant for my ventilation system and how do I apply for it?

Yes, often. Depending on your home and region, you may be entitled to the EPC label premium, a municipal grant or the reduced VAT rate of 6%. We check this during the site visit and help you with the application.

What do the 50% rule and the 70% rule mean for ventilation?

The 50% rule stipulates that at least half of the ventilated capacity must be able to be refreshed naturally if you choose a hybrid system. The 70% rule is a requirement for some renovation grants, where the system recovers at least 70% of the heat. Our advisor explains exactly which rule applies to you.

What is the difference between mechanical ventilation and balanced ventilation?

Mechanical ventilation extracts moist air through a central duct. Balanced ventilation (system D) does that too, but at the same time supplies fresh preheated air. The latter is more energy-efficient, but requires a larger investment. We go over the pros and cons with you.

How quickly can I make an appointment for a site visit?

We usually schedule an appointment within two working days. The expert from your region will coordinate the time with you, also in the evening or on Saturday if necessary.

Am I obliged to buy from you after the quote?

Absolutely not. Our quote is completely without obligation. We believe in clear advice and fair prices, not in pushy sales talk.

How often should a ventilation system be maintained?

A system C requires a filter change and cleaning of the grilles every two to three years. With balanced ventilation (system D), you replace the filters every three to six months and have the unit and ducts cleaned annually or biennially by an installer.

How much does ventilation system maintenance cost?

The price depends on the type and size. Replacing filters yourself costs around 30 to 60 euros per set. A professional maintenance service for system D ranges between 150 and 300 euros, including cleaning and inspection. Request a clear quote with separate line items.

Who performs ventilation system maintenance?

You can vacuum the grilles and change filters yourself. For deep cleaning, measurement reports and repairs, you should hire a certified ventilation installer. They have the right measuring equipment and follow the manufacturer's guidelines.

How should I maintain my system D ventilation?

For a system D, clean the supply and exhaust grilles every three months. Replace the filters every three to six months. Have the heat exchanger and fans checked annually by a professional. This way you maintain high efficiency and healthy air.

Is ventilation system maintenance mandatory?

The Flemish government does not impose a legal maintenance obligation, but manufacturers require periodic maintenance to maintain the warranty. Moreover, a dirty system does not meet the EPB targets and energy consumption increases. Many insurers ask for a maintenance certificate in case of damage.

What is the difference in maintenance between system C and D?

System C only has mechanical extraction: you clean the grilles and have the central fan checked every three years. System D also supplies air mechanically, so more filters and a heat exchanger need to be maintained. As a result, the annual costs and frequency are higher.

Thanks to our local approach, we are quickly on site and know the typical challenges of your region. Whether you live in a townhouse in Ghent or are planning a new build in Hasselt, we provide a tailor-made proposal.

Anyone who has a ventilation system installed often only looks at the purchase price. Yet periodic maintenance determines a large part of the total costs over fifteen years. Therefore, in your quote, do not only ask for the installation, but also have the expected maintenance costs included.

Different systems, different maintenance services

With a system C (mechanical extraction), a biennial check of the fan and cleaning of the ducts is usually sufficient. You can keep the filters in the grilles clean yourself. With a system D (balanced ventilation), count on a semi-annual filter change and an annual service by an installer. That service includes cleaning the heat exchanger, checking the fans and calibrating the sensors. Ask for a separate price for a maintenance contract: that gives certainty and spreads the costs.

What to look for in a maintenance contract?

Are filters and cleaning products included?
Is there a priority arrangement in case of breakdowns?
Is the maintenance carried out according to the manufacturer's instructions?
Does the installer provide a maintenance certificate?

By discussing these matters in advance, you avoid surprises and enjoy a quiet, economical and healthy ventilation system for years to come.
