Why should you consider an electrical service upgrade?

Your home’s electrical service determines how much electricity your appliances can use. Older homes typically have less than 200-amp electrical service. Electrical service upgrades increase your home’s value and prepare it for clean energy solutions like solar systems, heat pumps, and electric vehicles.

How to upgrade your electrical service

Talk to an electrician about how to upgrade your electrical service. A licensed electrician will perform the upgrade and work with your local permitting agency to ensure the job is code-compliant. This upgrade typically takes one day to complete, and usually costs $2,500 to $4,500, but can be more depending on your home.
