This is where homeowners often make the wrong comparison. If one electrician says "replace the breaker," another says "add a dedicated circuit," and another says "you need bigger electrical work," the right question is not which one is cheapest.
The right questions are what each person observed, what they tested, and what exact problem their scope claims to solve. That is why compare contractor bids when electricians disagree becomes the right next step as soon as the symptom turns into competing recommendations.
If the recommendations still feel vague, use what a valid contractor scope should include to pressure-test the written scope before you compare the totals.
