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. A service puts that right.

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.

Annual service

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