HIU & MVHR Engineering in Hounslow — A Local Guide
The stretch of Hounslow between Brentford and Chiswick has seen some of west London's densest apartment development. Brentford Lock West, Great West Quarter and the Kew Bridge developments are all network-connected, which is why HIU servicing demand in the borough has grown so sharply.
Many of these blocks are now 8 to 15 years old — the point at which unserviced HIUs start failing. We typically find scaled plate heat exchangers, blocked strainers, worn control valves and actuators that no longer respond correctly. Brands across the borough include Danfoss, SAV, Switch2 and Caleffi.
Brentford's riverside apartments are built airtight and ventilated by MVHR. Because these flats are compact and often occupied by families, moisture loads are high — and a neglected MVHR shows up quickly as streaming windows and mould. We service MVHR from £120.
