dehumidifier

[WrigleyF]

Does having a dehumidifier help protect your computer, or is one unnecessary with an air conditioner?

If you live in a humid area which results in condensation on indoor surfaces, then yes - you need a dehumidifier. Note, however, that condensation on the inside of windows may be normal.

To see if live in an area of high humidity, you can check the humidex (http://en.wikipedia.org/wiki/Humidex).
