MVHR servicing and filter changes
Annual service, filters, heat exchanger clean and a measured airflow check for existing MVHR.
Greater London · England
Homes, rentals and business premises in Balham and SW4, SW11 and SW12.
Damp walls, steamed-up windows, a noisy fan or a kitchen canopy that drips grease: each of these has a cause we can measure and a fix we can price before any work starts in Balham.
In many Balham homes the first step is better extraction in the kitchen and bathroom. If the windows still stream after that, a PIV unit or continuous fans usually finish the job.
For businesses in Balham we cover office and shop ventilation, commercial kitchen extraction, duct cleaning to TR19 and planned servicing of air handling units.
Annual service, filters, heat exchanger clean and a measured airflow check for existing MVHR.
Loft or wall units that gently push filtered air into the home to tackle condensation.
Bathroom, kitchen and utility fans sized to the Part F rates, ducted outside and tested.
We find why the house is wet and fix the ventilation, rather than painting over mould.
