The answer to 'types of ceiling fan installation' is there are several common methods for installing a ceiling fan, depending on the type of ceiling and existing electrical setup. The most common types of ceiling fan installation include new construction installation, retrofit installation, and replacement installation.
New construction installation involves wiring the ceiling fan circuit during the initial electrical work for a new home or addition. Retrofit installation is used when adding a ceiling fan to an existing room, which may require running new electrical wiring. Replacement installation is the simplest, where an old ceiling fan is swapped out for a new one using the existing electrical box and wiring.
