5 Star Electric installed a ceiling fan in our master bedroom. Tommy and Ian showed up on time ready to get the job done.  There was no fixture in the ceiling so they had to cut a hole in the ceiling, install a junction box, run wiring through the small crawl space in the attic down to the existing wall switch and cut an additional hole in the wall for the fan wall switch.  It works great, looks great and Tommy and Ian cleaned up thoroughly.  This is the second ceiling fan install 5 Star and done in our home.  I’m confident the job was done correctly.

Bathroom Fan Installation FAQs, answered by experts

Every municipality has its own codes. But generally speaking, all bathrooms must have some ventilation, whether it's a fan or a window. Check your local building codes before doing any bathroom fan installation to make sure you are meeting the code requirements. A reputable electrician or bathroom fan installer will be able to answer this question.

Once you remove all standing water and puddling, you should run fans for 24 to 48 hours to remove the remaining moisture. For severe water damage, it’s a good idea to run them for three to four days to be safe. Make sure you buy or rent the proper size and number of fans for your water-damaged area.

On average, a bathroom fan lasts between five and ten years. The fan's lifespan depends on its quality, installation, and frequency of use. You can extend its life with regular cleaning and by promptly addressing any issues. Common signs that you need a new fan include mold growth, a burning smell, unusually loud noises during operation, or lingering odors in the bathroom. If your fan is no longer working as well as it once did, consider replacing it. The cost to install a new bathroom fan is typically between $240 and $550.

Duct fans in HVAC systems last an average of 15 to 20 years. Because these fans operate in relatively controlled environments, they can maintain their efficiency for a long period of time. To maximize the lifespan of your duct booster fan, have your HVAC system maintained regularly.

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.
