Mechanical ventilation and heat recovery (WTW)
Fresh air without draughts: we install and replace mechanical ventilation units and heat recovery ventilation (WTW), lay the ducts and balance the system.
A price per job, not per hour. You see the price in your quote before we start.
What we do
Mechanical ventilation units
We replace old or noisy ventilation boxes and install new units, connected to the existing or new ducts.
Heat recovery ventilation (WTW)
A heat recovery unit uses the warmth of the extracted air to pre-heat incoming fresh air, so you keep the warmth inside while the air stays fresh.
Ducts, valves and balancing
We install insulated ducts and ceiling valves and balance the air flows per room.
Business projects
For businesses we also install extra extraction ducts, for example at production machines – where possible without stopping production.

Frequently asked questions
Why is ventilation important?
Good ventilation removes moisture and stale air and helps prevent mould, especially in well-insulated homes.
