If you're installing a ceiling fan for the first time on false ceiling, it is necessary to have a supporting structure for the fan. The false ceiling support must be able to bear the weight of the fan. If the fan needs to be serviced or replaced in the future, there is no need to open up the false ceiling again. The servicing can be done from the fan bracket below the false ceiling.
If there is an existing false ceiling support that is not done well, our electricians have the obligation to highlight it to you and discuss next steps.
