William did an excellent job installing two ceiling fans in our house. One was 18 feet high and required a lot of extra time to complete. We ran into an issue with a ceiling medallion, but they were very patient with us until we resolved the problem and we're very pleased with the results.
Turns out the other fan would not fit properly, so he had to come back after we found another to hang that one. William also diagnosed a couple other electrical issues we had at no charge. We would not hesitate to use his company in the future.

Details: Yes, the location has an existing fan • Ceiling • Greater than 8 feet high
