What the work involves

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.

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.
