"I cannot say enough good things about Abraham and his team. They were indispensible during a challenging and stressful move. Not only did they do a superb job of installing a ceiling fan to an 18ft ceiling, multiple patch repairs, seamlessly replacing and installing bathroom extractor fans that into non standard sized spaces, filling countless nail holes and repainting, and reattaching a dislodged dishwasher, Abraham did all of this amidst the chaos of a move and made MULTIPLE trips to Home Depot to color match paints when I provided the wrong cans. He was patient, thorough, and went WAY above and beyond any expectations in both service, execution, and generosity. If you have anything you need done in your home, make these guys your first call!"

Bathroom Fan Installation questions, answered by experts

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.

If you think your fan needs to be oiled, the first thing that you have to do is cut the power to the fan. The best and safest way to do this is by flipping the circuit breaker that leads to that room.  Depending on the model of your fan, you may need to remove a cover. Look for a hole labeled oil. If there isn't one, check the manual or look for schematics online. Once located, use the recommended lubricant or spray. 

Never add oil unless the fan is specifically designed for it. Most modern ceiling fans are designed with sealed bearings that don’t require oiling. However, some older fans may have oil ports for lubrication. If your fan is older and you hear squeaking or grinding, check the manual or the manufacturer’s website to see if oiling is recommended.

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.

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.
