Single-flow extract ventilation is the most common and most economical solution. Heat recovery ventilation recovers heat from the extracted air: it is best suited to new or very well-insulated homes.

Clogged vents reduce air renewal and encourage humidity. Regular cleaning of the vents and inspection of the unit keep it working efficiently.

An old or dirty unit can become noisy. We inspect the installation and, if necessary, propose replacing it with a quieter model.
