Your electrical panel is the heart of your home’s power system. If you’re adding a heat pump, EV charger, solar panels, or modern appliances to your Skokie, Wheeling, or Chicagoland home, your panel may not be able to handle the load. Here’s how to tell if you need an upgrade — and what it costs.
What Does Your Electrical Panel Do?
The electrical panel (also called the breaker box or load center) distributes electricity from the utility to every circuit in your home. It also protects your wiring and appliances with circuit breakers that trip when a circuit is overloaded.
Most older Chicago-area homes have 100-amp panels. That was plenty in the 1980s. But modern homes with central AC, heat pumps, electric dryers, EV chargers, and home offices often need 200-amp service.
7 Signs You Need a Panel Upgrade
1. Breakers Trip Frequently
If you’re resetting breakers every week, your panel is telling you it can’t keep up with demand. This isn’t just annoying — it’s a fire hazard if you keep pushing it.
2. You’re Adding a Heat Pump or EV Charger
A heat pump draws 15–60 amps depending on size. A Level 2 EV charger needs a dedicated 40–50 amp circuit. If your panel is already at capacity, these additions require an upgrade.
3. You Still Have a Fuse Box
If your home has a fuse panel (with screw-in fuses instead of flip switches), it’s outdated and potentially dangerous. Fuse panels can’t be expanded and don’t provide the same level of protection as modern breakers.
4. Lights Flicker When Appliances Start
When your AC kicks on and the lights dim, your panel is struggling to deliver enough power. This voltage drop can damage sensitive electronics over time.
5. You Use Extension Cords and Power Strips Everywhere
If you don’t have enough outlets and rely on extension cords, your home’s electrical system wasn’t designed for your current usage. A panel upgrade plus additional circuits solves this properly.
6. Your Panel Is Warm to the Touch
A warm or hot panel is a serious warning sign. It means connections are loose or the panel is overloaded. Call an electrician immediately if you notice this.
7. Your Home Insurance Requires It
Some insurers won’t cover homes with outdated panels (especially Federal Pacific, Zinsco, or Pushmatic brands). An upgrade may be required to maintain or obtain coverage.
How Much Does a Panel Upgrade Cost in Chicago?
- 100-amp to 200-amp upgrade: $2,000–$4,500
- Fuse box to 200-amp breaker panel: $2,500–$5,000
- 200-amp to 400-amp (large homes): $4,000–$8,000
These costs include the new panel, breakers, labor, permit, and ComEd coordination. The village of Wheeling, Skokie, Arlington Heights, and most Chicago suburbs require a permit and inspection for panel work — MMDS handles all of this for you.
What’s the Process?

Panel Upgrade + Heat Pump = Smart Combo
If you’re upgrading to a heat pump, it’s the perfect time to upgrade your panel too. MMDS handles both electrical and HVAC work in-house — no need to hire two separate contractors. One crew, one project, one point of contact.
Frequently Asked Questions
Do I need a permit for a panel upgrade?
Yes. Every Chicago suburb requires an electrical permit and inspection for panel work. MMDS pulls the permit and schedules the inspection as part of every job.
Will I lose power during the upgrade?
Yes, for approximately 2–4 hours while we swap the panel. We’ll schedule the work at a convenient time and let you know exactly when the power will be off.
Can I add circuits during the panel upgrade?
Absolutely. This is the ideal time to add dedicated circuits for a home office, workshop, EV charger, or any other high-draw equipment. A 200-amp panel has room for 40+ circuits.
What brands do you install?
We install Square D (Schneider Electric), Eaton, Siemens, and Leviton panels. All come with manufacturer warranties and meet current NEC code requirements.
