MVHR servicing for Llanelli homes
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.
