What MVHR servicing and filter changes involves
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. It is common for a system to go years without a filter change after the builder hands over.
Filter supply
The right filters for your unit, ready to change yourself between visits.
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.

Do I need to be at home for the service?
Someone needs to let us in and be there when we measure the valves, which means visiting every room. A service usually takes one to two hours.
My new build MVHR has never been serviced. Is that a problem?
It is very common and usually fixable. Builders often hand over without explaining filter changes, so the first service often finds filters that are badly blocked. We clean everything and reset the airflows.
