How long does a whole house surge protector last?
You can expect a whole house surge protector to last between 2 and 5 years. Because a surge protector’s functional lifespan is measured by the cumulative total of the number and size of the surges it absorbs, not years, any lifespan estimate is going to be a wide range. We are assigning an average lifespan of 3 years but, again, time is not the key factor. To find out the key features to look for when buying one, go to our blog post How do I find the right whole house surge protector?
And here’s a graph comparing the life expectancy of a whole house surge protector to other electrical components in a home.
