MVHR servicing for Hatfield homes
MVHR is often fitted and then forgotten. Over a year or two the filters clog, the fans work harder, airflow at the valves drops and the house slowly goes back to condensation and stale air.
Rebalance and recommission
Every valve measured and set again to the design rates, with a new commissioning sheet. Useful after building work or if rooms feel stuffy.
Filter supply
The right filters for your unit, ready to change yourself between visits.
