How we approach MVHR in Cheam
Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms. Inside the unit the two airflows pass each other across a heat exchanger without mixing, so the incoming fresh air picks up heat from the outgoing air.
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.

Rules that apply in England

Questions from Cheam
Do you cover Cheam and nearby?
Yes. We cover Cheam and nearby places including Sutton, Ewell, Belmont and Worcester Park. Send your postcode and we will confirm.
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.
Can MVHR cool the house in summer?
MVHR is not air conditioning, but a summer bypass lets cooler night air in without warming it, which helps take the edge off hot rooms. For real cooling you would need a separate system.
