How we do it

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. A service puts that right.

Annual service

Filters, exchanger and fan clean, drain check, controls and boost checked, airflow spot-checked at the valves.

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 about MVHR servicing and filter changes in Surrey

Is the survey free in Surrey?

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.

Why has my MVHR system gone noisy?

Noise usually comes from clogged filters making the fans work harder, a fan bearing wearing out, or valves that have been closed down. A service and rebalance fixes most cases.

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.

Which rules apply to ventilation in Surrey?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
