Ventilation for your house.
Condensation on the windows, a stuffy smell or a feeling that the air never really changes? Then your home probably lacks proper ventilation. With a ventilation system from Z-venti, you get fresh air 24/7 without having to open the windows and let the heat out.
Good ventilation is about more than comfort. Moisture that is not vented away can, over time, cause mold and damage to the building, which can affect both health and the value of the home. That's why we always adapt the solution to your specific home, regardless of whether it's a detached house, a townhouse or an apartment.
We install complete ventilation systems that cover the entire property. If you only have problems in one area, such as the basement or bathroom, a smaller solution for individual rooms can be both quicker to install and cheaper.
We start by looking at your home and your needs before we recommend anything. You get honest advice, a clear quote and a professional installation so you don't end up with a system that is larger or more expensive than necessary.

Ventilation system with heat recovery
A ventilation system with heat recovery exchanges the air throughout the home without releasing heat with it. The system sucks out the used, humid air from the kitchen, bathroom and toilet and blows fresh, filtered air into the living room and bedrooms. Along the way, a heat exchanger transfers most of the heat from the outgoing air to the incoming air. The fresh air is therefore already heated when it reaches the room.
What ventilation systems with heat recovery can give you.
-
Lower heating bills . You don't have to ventilate with open windows, and modern systems recover up to approximately 90% of the heat in the outgoing air.
-
Healthier indoor climate . Moisture, food odors and polluted air are continuously removed, reducing the risk of condensation and mold.
-
Cleaner air. The filters capture pollen and dust, which many allergy sufferers greatly appreciate.
-
Better night's sleep. Fresh air in the bedroom can provide a more peaceful and restful night without drafts or traffic noise from an open window.
-
Protection of the home . Stable humidity takes care of the construction and helps preserve the value of the home.
-
A ventilation system with heat recovery constantly replaces the used, humid air with clean, filtered air that has already been heated. This provides a better indoor climate and lower energy consumption without you having to think about it in your everyday life.
If you want a complete solution, we can also deliver systems with a cooling function and heat pump, so you get a comfortable temperature and fresh air all year round.
We use the best quality

one room ventilation solution with heat recovery
Are you dreaming of ventilation in one room where condensation, moisture and poor air quality are a nuisance? We have a solution.
With a one-room system with heat recovery, you solve the problem right where it occurs. In your bathroom, bedroom, kitchen or basement.
The system removes the humid, used air and lets fresh air in instead. Along the way, most of the heat in the outgoing air is transferred to the incoming air, so you don't send expensive heat out of the house. This provides a better indoor climate without unnecessary losses on your heating bill.
The installation is less extensive than a complete system, and the price is significantly lower, but the effect is clearly felt where the need is greatest.
Are you unsure whether you need a single room or the entire home? We will look at your property and recommend the solution that makes the most sense for you.
get a Home improvement services deduction and better air quality
Did you know that the state can cover part of the bill when you have ventilation installed?
With the green craftsman deduction, you can deduct part of the cost of wages from your tax. This applies to both a complete system for the entire home and a smaller solution for individual rooms.
In 2026, you can deduct up to DKK 9,000 per adult in the household. That is, up to DKK 18,000 if there are two of you over 18 in the household.
At Z-venti you don't just get fresh air. We also make sure that your invoice is clear and specifies the wages, so it's easy for you to make use of the deduction.

maintenance of your ventilation system
A ventilation system works best when it is clean. Over time, dust, grease and, in the worst case, mold accumulate in ducts and filters. This affects air quality, makes the system work harder and can shorten its lifespan in the long term.
At Z-venti, we service the entire system, from filters and units to the ventilation ducts themselves, with professional equipment that is made for the task.
Whether you have a solution from Genvex, Nilan, a third-party ventilation system or a ventilation system with heat recovery, Z-venti adapts the cleaning to your system.
Regular servicing:
-
Reduces energy consumption
-
Improves air quality noticeably
-
Extends lifespan
In other words, service results in better air quality, longer system life and lower energy bills.
Has it been a long time since your system was last cleaned? Contact Z-venti and we will find out what is needed.
