Changing a loud bath fan

Newer-style bath fans, on the other hand, are so peaceful you can barely hear them running, and they cost really little to run. It’s simpler than you believe to switch out that loud, ineffective bath fan, specifically if you pick one that’s developed to be set up without removing the restroom ceiling.

Of the numerous replacement designs to select from, we selected the NuTone No. RN110 Ultra Pro Series since the fan can be set up from inside the restroom. It’s not the quietest design offered, however at 0.6 sones (about 25 decibels), it’s a big enhancement over the old 4-sone (about 60 decibels) fan we’re changing. If you can find a joist, cut drywall and deal with standard electrical work, you can do the entire task in about 2 hours and conserve about $200 on the setup. You’ll require a stud finder, a drywall saw, a drill and screws, and aluminum duct tape.

Purchase the best size for your restroom

There’s no such thing as a ‘‘ one-size-fits-all’ bath fan. For restrooms approximately 100 sq. ft., determine the needed cubic feet per minute (cfm) by increasing the space’s length x width x height. Multiply that outcome by.13 and assemble to the closest 10. Example: 10 ft. broad x 9 ft. long x 9 ft. high x. 13 = 105. Assemble to 110 and purchase a 110-cfm bath fan. For restrooms bigger than 100 sq. ft., merely build up the cfm requirements for each of these pipes components: toilet, 50 cfm; shower, 50 cfm; bath tub, 50 cfm; jetted tub, 100 cfm.

Switch off the power prior to continuing

You’ll need to get rid of the power cable television from the old system and link it to the brand-new fan. This should be finished with the power off. Do not depend on switching off the fan switch; turn the breaker also. Then confirm that the power is off with a voltage sniffer. If you’re not comfy dealing with electrical power, employ an electrical expert to get rid of and link the wires.
