The answer to 'difference between ceiling fan installation' is that there are two main types of ceiling fan installation: direct-wired and plug-in. Direct-wired ceiling fans are hardwired directly into the electrical box in the ceiling, requiring more complex installation by a licensed electrician. Plug-in ceiling fans simply plug into a standard electrical outlet, making them easier for a homeowner to install themselves. The choice between the two depends on your electrical setup, skill level, and budget.
Direct-wired ceiling fans provide a more permanent, secure installation, but require running new electrical wiring which can be more costly. Plug-in fans are a simpler, more DIY-friendly option, but may not be as aesthetically seamless or secure as a hardwired installation. Ultimately, the best choice depends on your specific needs and comfort level with electrical work.
