What Is an Electrical Service Upgrade?

An electrical service upgrade increases the total amount of electricity your home can safely manage. This process typically includes:

  • Replacing your old electrical panel with a larger, modern breaker panel
  • Installing a new meter base and service mast to meet utility company requirements
  • Replacing outdated wiring and grounding systems
  • Upgrading the incoming service line if needed
  • Making space for additional circuits to accommodate your growing power needs

Most older homes are equipped with 60-amp or 100-amp panels. Today, 200 amps is considered the new standard—especially for homes that use central air, electric heat, or EV chargers.

Common Signs You Need a Service Upgrade

You don’t need to be an electrician to know when your home is struggling to keep up. Here are some everyday signs that your system might be outdated:

  • Frequent breaker trips — especially when running appliances simultaneously
  • Flickering or dimming lights when large equipment like a vacuum or microwave kicks on
  • Outlets that spark or feel warm to the touch
  • Appliances or electronics not running at full capacity
  • No available space in your breaker panel for new circuits
  • You still have a fuse box instead of a modern breaker system
  • Home renovations or additions are planned
  • You’ve added high-demand items like an EV charger, hot tub, or new HVAC system

If you’ve experienced any of these issues, it’s likely time for a professional evaluation.

What We Upgrade

At A+ Derr, we take a personalized approach to every service upgrade, starting with a deep understanding of your current infrastructure and what you need it to support moving forward. Whether your goal is to make room for a new kitchen, accommodate a growing family, or simply bring your home’s power supply into the 21st century, our upgrades are designed around your priorities, your lifestyle, and your home’s long-term value.

Main Electrical Panel Replacement

We swap outdated or overloaded panels for modern, high-capacity breaker panels with room to grow. This gives your home a solid foundation to handle everything from everyday use to future electrical upgrades.

Meter Base & Service Mast Installation

Your utility provider relies on your meter base and service mast to safely deliver power to your home. We ensure these components meet modern utility and safety requirements, including proper mounting, weatherproofing, and clearance.

Grounding & Bonding

We update grounding systems to meet today’s electrical code, which helps protect your home and appliances from dangerous surges or electrical faults.

New Circuits for Future Loads

Whether you’re planning to finish your basement, install a workshop, or add a second oven, we can include additional circuits during the upgrade to future-proof your home.

When to Consider a Service Upgrade

Still on the fence about whether an upgrade is necessary? Here are some common situations where it’s not just a good idea—it’s a must:

  • You’re Renovating or Expanding Your Home: Adding square footage or reconfiguring rooms often means adding outlets, lighting, and larger appliances. If your panel can’t support those new loads, an upgrade is essential.
  • You’ve Recently Added an EV Charger, Hot Tub, or High-Efficiency HVAC System: These modern amenities draw serious power. If your panel was installed before these became common, it’s likely not equipped to handle the demand.
  • You’re Constantly Tripping Breakers: This isn’t just annoying—it’s your system telling you it’s overwhelmed. Upgrading your service can restore consistent, safe power.
  • You Plan to Sell Your Home: Buyers notice the age and capability of electrical panels. An upgraded service can boost home value and appeal.
  • Your Home Still Has a Fuse Box: Fuse boxes are outdated and generally not considered safe by modern standards. It’s time to move to a breaker-based panel system.

In all of these cases, upgrading your electrical service isn’t just about staying current—it’s about keeping your home safe, functional, and ready for the future.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
