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.

Questions from Swansea
Do you cover Swansea and nearby?
Yes. We cover Swansea and nearby places including Clydach, Briton Ferry, Gorseinon and Neath. Send your postcode and we will confirm.
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.
What is the price of an MVHR service in Swansea?
Guide prices for Swansea use Wales rates: MVHR service: filters, unit and heat exchanger clean, airflow check is typically £140 to £235 inc VAT per visit. We confirm a fixed price in writing before any work starts.
Is the survey free in Swansea?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
If the system in your Swansea home needs more than a service, we will explain why and price it before doing anything.
