"David did an outstanding job installing our bathroom exhaust fan. We were able to schedule the installation within a few days of my initial call. His rate was the most reasonable of three companies I called through Home Advisor. Very professional and will call him again if we need more work done at our home. I recommend him highly!"

"The installation was started on time and was completed on time as we had discussed and listed in the contract. I gave the contractor a key to my home to let himself in as the work was being done while I was at work. The contractor took very good care of my home and he cleaned up every day before he and his crew left.
The contractor was very professional and responded to all my questions and concerns in a timely manner.

"Nestor and team were very professional and punctual. They installed a ceiling fan in my bedroom where there was no wiring/fixture, so they cut holes in the walls/ceiling to pull over the wiring, installed the fan, and then patched and pained everything. When they left they cleaned up everything and you couldn't tell there had been holes in the ceiling just hours before. The whole thing took about 6 hours to do."

"“I strongly recommend JW Home Improvement for all home repair and renovation needs. Over the past few weeks we have had various projects completed, including, exhaust fan installation, stairwell repair, dry wall repair, exterior dormer and trim replacement and gutter/downspout painting. All of the technicians were friendly, prompt, knowledgeable, respectful, highly skilled and operated efficiently to finish ahead of scheduled time. Pedro, Kevin and Antonio in particular were exceptional in going above and beyond to produce truly beautiful work. The craftsmanship and precision displayed by these technicians was extraordinary and they were an absolute pleasure to have in my home.”"

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.

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.

Whole-house fans cost significantly less to run than a window AC unit. You'll pay an average of $0.01 and $0.05 per hour to run a whole-house fan compared to $0.06 to $0.88 per hour for the cost to run a window AC, depending on its size and the size of your home. They also use far less electricity than traditional central AC units.

The most efficient ceiling fan height is 8 to 9 feet from the floor to the fan blades. For ceilings higher than 9 feet, a downrod can be used to lower the fan to the optimal height. This positioning ensures adequate air circulation and maximizes the cooling effect. Remember, fans should be installed at least 7 feet above the floor for safety.

A whole-house fan works best to pull chilled and dry air into your home in the early morning hours and at night. This system allows you to close your windows after turning off the fan and trap the cool air inside. You can run your whole house fan continuously for maximum ventilation and fresh air, or you can turn it on for ten minutes or so at a time to introduce cool, fresh air as needed.
