While looking for a contractor to handle your bath exhaust fan repairs, there are a few things that you should always keep in mind. Primarily, you should be sure that you are working with a contractor who has a complete understanding of proper mold removal. Mold is not an uncommon sight inside of bathroom exhaust fans and it needs to be dealt with properly. When it's not disposed of in the correct manner, mold can get agitated and fall out of your exhaust fan while it's being repaired. This can leave you open to exposure and should therefore be avoided.

Be sure that you are working with a contractor who understand electronics well. Some contractors may constantly default to the "replace everything" mentality every time there's a fan problem. This can be very costly, so you want to be sure the contractor you hire has enough experience with electronics to be affordable. This also leads into how important it is for you to learn about your contractor's previous work history. It's good to know this type of thing in advance.
