What the work involves
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.

Questions from Belfast
Is the survey free in Belfast?
Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
How often should MVHR filters be changed?
Most manufacturers recommend changing MVHR filters every 6 to 12 months, and more often near busy roads or building sites. A full service once a year is a sensible minimum.
