How we approach MVHR servicing in Penarth
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. It is common for a system to go years without a filter change after the builder hands over.
Fault finding
Noisy fans, error codes, condensate leaks and boost controls that stopped working.
Annual service
Filters, exchanger and fan clean, drain check, controls and boost checked, airflow spot-checked at the valves.
