How we approach MVHR servicing in Dorking
It is common for a system to go years without a filter change after the builder hands over. A service puts that right.
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.

Questions from Dorking
Is the survey free in Dorking?
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.
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.
