"Cole was very professional, installed a kitchen ceiling fan, a bathroom fixture, high hats in the living room, and installed 2 outlets and moved my plate for my landline. He cleaned up and there was nothing for me to do after he left except admire his work."

"I retained Fielack to install a ceiling fan and relocate two electrical boxes. When they arrived to do the work, they explained that they only had to relocate one electrical box to accomplish what I wanted. Dave and Kory relocated the box and hung our new ceiling fan. They were prompt, courteous, clean and completely professional. I would not hesitate to hire them again."

"We were extremely happy with the work performed by H&M. Moises, Hector and crew were courteous and did whatever needed to please us. They did most of the renovation in our condo......painting, installation of bathroom cabinets, sink, installed tile floor, etc. They also installed vinyl flooring in our kitchen, living and dining rooms. They had a plumber replace our heating baseboard, I would highly recommend H&M if you want excellent work done!!"

"The guys who work for Mr Handyman are seasoned journeyman carpenters and painters and know what they are doing. They completely gutted a small bathroom with shower and went above and beyond. We also used them for more handyman-type projects in our kitchen and Joe tackled many projects in just a day. Would highly recommend."

Bathroom Fan Installation questions, answered by experts

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Some disadvantages of a blower cooler—a type of cooling device sometimes known as a swamp cooler—are its increased energy demand and its higher noise level. Blowers require more energy to run because they push air out at a higher pressure. This also means a blower cooler can be louder than a fan. Blower coolers are also not recommended for humid areas because humidity limits their cooling potential.

Yes, you can oil an electric fan with machine or motor oil but don’t use cooking oil because it can become thick or seize up, damaging the fan. Before oiling your fan, turn it off and remove any dust and debris. Wipe away any excess lubricant after oiling.

Selection relies on matching fan size and power to attic volume and ensuring compatibility with home electrical systems and ventilation requirements.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.
