How we approach MVHR servicing in Cardiff
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 Cardiff
How do I get a price for an MVHR service in Cardiff?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
