What the work 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.
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.

Rules that apply in England

Questions from Barnes
Is the survey free in Barnes?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
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.
How much does an MVHR service cost?
An MVHR service usually costs £145 to £245 including VAT, depending on the unit and how easy it is to reach. Filters are included for most common units; rebalancing every valve is priced separately at £245 to £445.
