MVHR installation in Dyfed

We survey Dyfed homes for MVHR before quoting, because the duct routes decide the price more than the unit does.

Our team is based in Great Barr, Birmingham, and we work throughout Dyfed, from Aberystwyth, Carmarthen, Haverfordwest, Milford Haven and Llanelli. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

A single unit, usually in the loft, a utility cupboard or a garage, runs all the time at a low, quiet speed. Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms. Inside the unit the two airflows pass each other across a heat exchanger without mixing, so the incoming fresh air picks up heat from the outgoing air.

Retrofit in an occupied home

Ducts routed through the loft and down through cupboards or boxed corners. Most semis are done in 3 to 5 days.

New build or full renovation

Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Radial semi-rigid ducting

One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Questions about MVHR installation in Dyfed

Which towns in Dyfed do you cover?

All of Dyfed, including Aberystwyth, Carmarthen, Haverfordwest, Milford Haven and Llanelli. If your town is not listed, send the postcode and we will confirm.

How noisy is MVHR?

Correctly sized and balanced MVHR is very quiet on normal speed; most people stop noticing it within days. Noise problems usually come from undersized ducts or a unit running flat out, which is why we design the rates first.

How often does MVHR need servicing?

Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.

Are prices different in Dyfed?

Our guide prices are adjusted by region. In Dyfed we use Wales rates, so whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,225 to £6,600 inc VAT per home.
