MVHR for Llanelli homes
Filters on both sides keep pollen and dust out of the house and keep the exchanger clean. MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.
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.

Questions from Llanelli
Do you cover Llanelli and nearby?
Yes. We cover Llanelli and nearby places including Gorseinon, Swansea, Ammanford and Clydach. Send your 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.
