A Maryland home averages 929 kWh a month, about 1.3 kW of continuous draw, so the big new loads (an EV charger, a heat pump, an induction range) are what push a panel past its limit, not everyday use; a load calculation tells you whether you need a service upgrade or just a few breaker spaces.

How to choose an electrician in Maryland
Verify the license and insurance
Electrical work in Maryland must be done or supervised by a licensed electrical contractor, and the license should be in the name of the company quoting you, not a friend of the crew. Look it up on the licensing board linked below, ask for proof of liability insurance, and confirm the contractor, not you, pulls the permit and schedules the inspection.
Start with a load calculation, not a panel size
For a panel upgrade, a new 240V circuit, or any electrification project, a good electrician runs the NEC Article 220 load calculation on your home before quoting. It decides whether you need a 200 A service upgrade (which involves the utility and the meter), a panel replacement at the same service size, a subpanel, or a load-management device that avoids the upgrade entirely. A quote that jumps straight to "200 amp upgrade" without the math is a guess.
Compare written quotes on the same scope
Get at least three quotes that name the panel brand and ampacity, the number of spaces, breaker types required by code (AFCI, GFCI), the wire gauge and run length for new circuits, whole-house surge protection, drywall repair, the permit and inspection fees, and the utility coordination. Ask what happens if the inspector flags existing issues, such as aluminum wiring or a missing ground, and whether those fixes are priced in.
What to know before hiring in Maryland
The largest utilities serving Maryland homes are Baltimore Gas & Electric (1,025,745 residential customers, 17.9¢/kWh), Potomac Electric Power (485,483 residential customers, 20.1¢/kWh) and The Potomac Edison (240,570 residential customers, 13.8¢/kWh). Your utility sets the rate your new circuits draw from, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.
