In general at Surge-Protectors.org, a whole house protector will protect very well AC only devices, such as appliances, air conditioners, etc. They are not as good for protecting electronics that are connected to more than power hence you need to separately protect your sensitive electronic equipment no matter what "whole house" surge protector you use. Whole house surge protection is a badly used term, no manufacturer can make devices to protect everything in your home from all sources, it doesn't work that way. Be aware that a whole house protector allows more voltage through than a point of use protector, this is not good for computers and home theater systems. They are very useful for protecting all of the other devices in your house like appliances, air conditioners, etc., and for stopping outside surges as a first line of defense.

Whole house surge protectors that connect to your electric panel are generally tougher to find. The two primary sources are your local utility company and supply houses that sell electrical equipment / supplies to electricians. Hence if you want whole house surge protection then visit us at Surge-Protectors.org for guideline.
