I imagine that a whole house conditioner would be meant to address problems with power coming into the house. If the problem is inside the house, it probably isn't the best solution.
Most power surges are external, coming into the house from outside wiring. However, a whole house surge protector would still protect against internal surges, since all the wiring is essentially in parallel. This is especially true if a surge originated on a different circuit than a susceptible device is on because the surge would have to reach the panel (thus the protector) before going to the device's circuit. Internal equipment and wiring is more likely to generate electrical noise, brownouts and power sags. A conditioner would help against noise but you would likely need a UPS for brownouts and sags. Both a conditioner and UPS would usually also provide surge protection. -- Scott
