To ensure appropriate ventilation inside the home, bathrooms and other moist areas should have an exhaust fan. And while most current homes have one that are already installed, some older houses do not.

If a homeowner is thinking of installing an exhaust fan and he is unsure about how to do it, then his safest bet is to call up an HVAC professional to help him do the job.

For those who may want to give it a try, some books, as well as the Internet is a good source of step-by-step instructions to help with this type of home project.
