How we approach MVHR servicing in Codicote
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.
Annual service
Filters, exchanger and fan clean, drain check, controls and boost checked, airflow spot-checked at the valves.
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.
