Most water heaters last 8–12 years, and the decision to replace rather than repair usually comes down to age, rust in the water, or a tank that's already leaking. Long's Plumbing evaluates the unit on-site and gives homeowners in Merrimack, NH a clear answer — repair if it makes sense, replace if it doesn't — rather than defaulting to the more expensive option.\n\nThis straight-talk approach is part of why customer reviews consistently point to Long's Plumbing diagnosing the real issue instead of pushing unnecessary work. Replacement service in Merrimack, NH includes removal of the old unit, proper disposal, and installation of a correctly sized replacement, typically completed the same day the tank fails.
