More enquiries for ventilation installers
Marketingkenners makes sure you get your own enquiries as a ventilation installer for mechanical ventilation, heat recovery (WTW) and balanced ventilation. With a website, Google Ads and Google Maps, tracked all the way to the signed quote.
100+ businesses and growing
Marketingkenners helps installers of mechanical ventilation, heat recovery (WTW) units and balanced ventilation get their own enquiries. Your website explains per system what it delivers, with photos of your own installations, and the form asks for the type of home, year of construction and current system. Google Ads runs all year and gets extra budget from October to January, tracked all the way to the signed quote.
The customer often doesn't know what is installed now
Many enquiries start with a complaint. The unit in the loft is noisy, the bathroom stays damp or there is condensation on the windows. The customer often doesn't know whether they have a standard ventilation unit or a heat recovery (WTW) unit, or whether replacing it or a new system is the better choice.
With a renovation or after insulating, another question comes up: is balanced ventilation needed now that the house is airtight? That is bespoke work, with ducts, a place for the unit and balancing afterwards. Many installer sites have one general page about indoor climate, with no explanation per system and no photos of their own work.
Then the customer chooses on price or on whoever calls back first. A good enquiry states the type of home, the year of construction, the current system and whether it is a replacement or a new installation. If you also do central heating, heat pumps or air conditioning, also take a look at marketing for installers.

What the Growth System does for a ventilation installer
Six parts that make sure you get chosen for the whole system, not just for a new unit.
A page per system
Separate pages for mechanical ventilation, heat recovery and balanced ventilation, with photos of your own installations and explanations about noise, filters and maintenance.
Ads on replacement and installation
Google Ads on terms such as “mechanische ventilatie vervangen” and “wtw installatie” in your service area. We exclude searches for loose filters and grilles.
Found in your region
A strong Google Business Profile with reviews and photos of completed units, so you show up in Google Maps.
Home and system up front
The form asks for the type of home, year of construction and current system. So you know whether it is a unit swap or new ducts through the house.
Tracking to the quote
We follow every enquiry through to the signed quote. You see whether replacements or new heat recovery systems bring in more per euro of ad budget.
One installer per region
We work with one company per trade per region. A ventilation installer in your area does not get this approach from us as well.
This is how we start together
First the foundation, then buying traffic. That is how it starts in 9 out of 10 cases.
Intro call
We look at your service area, the balance between replacements and new systems and how you win jobs now. Then we tell you honestly whether the system is a fit for you.
Week 1: baseline
We set up tracking all the way to the quote, including phone calls. So we know how many enquiries come in now before we change anything.
Month 1: the foundation
Your website gets a page per system, photos of your own installations and a form that asks about the home.
Months 2 and 3: Google Ads
We start campaigns on buying intent, ideally in time for the busy months from October. From month 3 we work on SEO for searches like “balansventilatie”.
Shared leads or your own jobs
Lead platforms and separate parties
- An enquiry for a new unit often goes to several installers

With Marketingkenners
- The enquiry comes in through your own site and profile
- The customer chooses on explanation, your own work and reviews

More about ventilation
“mechanische ventilatie” is searched 12,100 times a month in October, November and January. In April, May, July and August that is 8,100, about two thirds. “wtw unit” follows the same pattern, with 6,600 in the peak months and 3,600 in July and August, just over half.
For “ventilatie badkamer” the gap is bigger: 2,400 in October against 880 in July and August. That coincides with the months when windows stay shut and damp and a noisy unit stand out more.
So demand never stops and you can advertise all year. Your budget in Google Ads goes up from October to January. In summer we steer on bigger jobs, such as balanced ventilation during a renovation, and prepare the campaigns for autumn.
October, November and January: highest search demand · April, May, July and August: about two thirds · Bathroom ventilation: almost three times higher in October than in July

Frequently asked questions

Yes, if you steer on people who want something done. People searching for “mechanische ventilatie” also include those who only want information or a filter. That is why we mainly advertise on terms such as “mechanische ventilatie vervangen” and “wtw installatie” and exclude searches for loose parts.
In month 1 we lay the foundation: website, form and measurement. In months 2 and 3 the ads start, and from then on enquiries come in through those campaigns. How many varies per region and season; we make no promises about numbers.
No. We work with one company per trade per region. If your region is already taken by another ventilation installer, you will hear so in the intro call.
That depends on your service area, your current site and how fast you want to grow. We don't name an amount on the site. In the free intro call you get a proposal that fits your situation.
Not always. What matters is that your site explains what you do per system and has a form that asks about the home and the current installation. In 9 out of 10 cases we improve that foundation first and only then the traffic.
