MVHR in Dorchester works the same way as anywhere else: a quiet unit, a duct to every room and a proper airflow test at the end.
Whether the property is in the middle of Dorchester or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

What the work involves
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. We check this on survey and tell you plainly if a simpler system would do the job for less.
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 Dorchester
How do I get a price for MVHR in Dorchester?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
