What the work involves

Common faults include worn fan bearings, failed capacitors and motors, condensate leaks, blocked filters, crushed or disconnected ducts, broken controls and humidity sensors that never switch the fan on. Sometimes repair is not worth it, and a modern replacement is cheaper to run; we will say so. For homes, a visit covers fans, PIV and MVHR.
