Fitting MVHR in a Gorseinon home starts with where the unit can live and how ducts reach each room.
Whether the property is in the middle of Gorseinon or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

What the work involves
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. Filters on both sides keep pollen and dust out of the house and keep the exchanger clean.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Questions from Gorseinon
What is the price of MVHR in Gorseinon?
Guide prices for Gorseinon use Wales rates: whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,225 to £6,600 inc VAT per home. We confirm a fixed price in writing before any work starts.
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.
Can MVHR cool the house in summer?
MVHR is not air conditioning, but a summer bypass lets cooler night air in without warming it, which helps take the edge off hot rooms. For real cooling you would need a separate system.
Is the survey free in Gorseinon?
