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.
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.

Questions from Caerphilly
How do I get a price for an MVHR service in Caerphilly?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
My new build MVHR has never been serviced. Is that a problem?
It is very common and usually fixable. Builders often hand over without explaining filter changes, so the first service often finds filters that are badly blocked. We clean everything and reset the airflows.

All of Gwent. Near Caerphilly that includes Rhiwbina, Whitchurch, Risca and Pontypridd.
