How we do it

It is common for a system to go years without a filter change after the builder hands over. A service puts that right. We work on most makes of MVHR unit and can supply filters for future changes, so you can do the in-between swaps yourself if you would rather.

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.

Fault finding

Noisy fans, error codes, condensate leaks and boost controls that stopped working.
