91. If my electrical panel feels warm but I haven’t noticed frequent breaker trips or dimming lights, should I still be concerned and consider upgrading?

    1. A warm electrical panel can indicate overloading or loose connections, even without other symptoms. It’s smart to have a licensed electrician inspect it soon to ensure safety. An upgrade might be needed depending on their assessment.

92. You mention budgeting, but how much does a typical panel upgrade cost including permits and inspections, especially if I hire some professional help for parts of the process?

    1. A typical electrical panel upgrade in the U.S. can cost between $1,500 and $4,000, including permits and inspections. If you hire professionals for parts of the job, expect the cost to be on the higher end of that range.
