How we do it

Filters on both sides keep pollen and dust out of the house and keep the exchanger clean. MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit.

New build or full renovation

Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Radial semi-rigid ducting

One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Summer bypass and boost controls

Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Questions about MVHR installation in County Down

Is the survey free in County Down?

Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.

How noisy is MVHR?

Correctly sized and balanced MVHR is very quiet on normal speed; most people stop noticing it within days. Noise problems usually come from undersized ducts or a unit running flat out, which is why we design the rates first.

How often does MVHR need servicing?

Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.

Which rules apply to ventilation in County Down?

In Northern Ireland, ventilation is covered by Technical Booklet K of the Building Regulations (Northern Ireland). Workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
