Questions from Carmarthen
Is the survey free in Carmarthen?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
Is it worth repairing an old extractor fan?
Usually not for a basic bathroom fan, because a new fan costs little more than the repair. MVHR, PIV and commercial fans are often worth repairing.
Why is my extractor fan humming but not spinning?
A humming fan that does not spin often has a failed capacitor, seized bearing or obstruction. It should be switched off until repaired.
