With all the electronic in are houses today does anyone have any thoughts on whole house surge protectors ( cost?)
The definitive decision is still out. Nothing is foolproof or guaranteed.
The local electric company tried selling this service a few years ago. I don't believe that they got enough interest generated to continue the option.
It was pricey in the long run. Statistically, it may be wasted money.
In 2004 my mother's house took a hit. A hurricane took out a tree branch and the weatherhead to the meter pan. The resulting surge took out a couple of ceiling fans, microwave, her VCR and other smaller electrical gadgets; didn't harm the larger appliances.
Yes, it cost several hundred dollars for the family to replace the damaged equipment but it was nowhere near meeting the insurance deductible ($1000).
When the electric company offered the surge service the cost of the deductible would have been met in four years.
Here she is 12 years later and no problems. The probability still exists that she could take a hit but statistically it is very unlikely. If she had opted for the service she would be $3000+ poorer. That cost would continue to grow by $1000 with each four years that passes.
Please do the research. It may or may not be worth it. If your area has a higher probability of lightning strikes or power surges then it may be worth it. If not, then...
