Hurst, TX Electrical Panel & Service Upgrades — More Power?

Wondering if you can upgrade a breaker box for more power? Yes, in many cases you can increase capacity safely by adding circuits, a subpanel, or a full electrical service and panel upgrade. If your lights dim when the AC starts, breakers trip often, or there is no space for a new EV charger or hot tub, this guide explains your best options and what code now requires.

What “more power” really means in a home

More power usually means one of three things: more breaker spaces for new circuits, higher amperage capacity, or both. The breaker box, often called the electrical panel, distributes power from the utility to each circuit in your home. If the panel is full, outdated, or the service size is too small, you may not have the capacity to add modern loads like EV chargers, generators, or additional HVAC equipment.

Key points to understand:

1. Panel space vs. service size are different. You might have space but not enough amperage, or enough amperage but no spaces left.
2. Heat and nuisance trips indicate stress. Frequent trips, warm breakers, or buzzing are warning signs of overloaded circuits or deteriorating components.
3. Safety first. An upgrade is about capacity and safety. Proper grounding, bonding, and surge protection reduce fire and equipment risk.

Signs you may need an upgrade or additional capacity

Common red flags our electricians evaluate include:

1. Frequently tripping breakers or lights that flicker when big appliances start.
2. Burning smells, buzzing, or crackling at the panel.
3. Warm or discolored breakers, rust, or corrosion on panel parts.
4. Outdated fuse boxes or panels that are full with no room to add a breaker.
5. New electrical needs like EV charging, hot tubs, home offices, or additional HVAC units.

If you see any of these issues, schedule an inspection. We start with diagnostics to decide whether repair, a targeted breaker or wiring fix, a subpanel, or a full service and panel upgrade is the right call.

Can you just add more breakers or tandem breakers?

Sometimes. If your panel is listed to accept tandem breakers, adding them can create space for new circuits. If it is not listed for tandems, forcing them in is unsafe and a code violation. Also, tandems do not increase the home’s amperage capacity. They only add spaces.

When tandems are not allowed or when loads are heavy, we may recommend:

1. A subpanel to add spaces while keeping the existing main panel.
2. A dedicated circuit for the new device, routed to available capacity.
3. A full panel replacement if the panel is obsolete, damaged, or unsafe to modify.

We inspect labeling, bus condition, breaker types, and manufacturer specifications to keep everything listed and compliant.

When a full electrical panel upgrade is the smarter move

A full upgrade is often best when:

1. The existing panel is deteriorated or has corrosion, burnt lugs, or overheating.
2. There is no available space and the loads are growing.
3. The home still uses fuses or a known problem panel model.
4. You are adding significant new loads like an EV charger, a whole-home generator interconnect, or an additional AC system.

Our diagnostic-first approach protects your budget. We identify what is actually failing and replace only what needs replacement. If a targeted fix will safely solve the problem, we recommend that over a full swap.

Service size: 100A vs 150A vs 200A and beyond

Many older DFW homes still run on 100-amp service, which can be tight for today’s appliances, HVAC, and EV charging. Upgrading to 150A or 200A provides headroom and reduces the risk of nuisance trips under peak demand.

Considerations when choosing service size:

1. Existing and future loads. EV charging, electric ranges, heat pumps, and hot tubs add up quickly.
2. Utility coordination. Meter base and service conductors may need upgrades to support larger service.
3. Space and code. The panel location must meet clearance rules. If it is in a closet, bathroom, or under a staircase, relocation may be required.

We calculate load, check conductor sizing, and coordinate meter or service upgrades so your capacity matches your plans.

What a breaker box upgrade typically involves

Here is the general flow homeowners can expect:

1. Inspection and load calculation to decide between repair, subpanel, or full upgrade.
2. Permits, utility coordination, and scheduling to reduce downtime.
3. Panel replacement or subpanel addition with labeled circuits and updated grounding and bonding.
4. Dedicated circuits added for new loads like EV, generator interlock, hot tub, or new HVAC.
5. Whole-home surge protection installed at the panel to protect electronics and appliances.
6. Final testing, labeling, cleanup, and inspection sign-off.

We keep job sites clean and communicate throughout, so you always know what is happening and why.

Code updates that affect today’s upgrades

Modern projects include safety features that older homes did not have:

1. Arc-fault and ground-fault protection where required by the NEC.
2. A service disconnect where required by newer code cycles.
3. Whole-home surge protection. Since the 2020 NEC update, basic surge protection is required in new or replaced services.

We design upgrades to align with the current adopted NEC, local amendments, and utility requirements in the DFW area.

Costs, permits, and timelines in DFW

Every home is different, but three variables drive price and schedule:

1. Scope of work. Repair vs. subpanel vs. full panel and service upgrade.
2. Code and site factors. Relocation for clearance, grounding corrections, and required AFCI/GFCI devices.
3. Utility and permitting. Meter or service upgrades require coordination with the power company and inspection timelines.

Expect most panel replacements to be completed in one day, with power off for several hours. Service upgrades that involve the utility can extend the overall timeline. We provide clear estimates upfront, easy payment options, and handle permits and inspections.

Smart alternatives to a full upgrade

Not everyone needs a complete overhaul. Depending on diagnostics, we may recommend:

1. Load balancing and dedicated circuits for heavy appliances.
2. A properly sized subpanel to add safe, listed breaker spaces.
3. Targeted breaker or bus repairs when components have failed.
4. Managed EV charging that limits draw to available capacity.

These options can deliver what you need without the cost of a full service change, provided they meet safety and code requirements.

Why choose a local, licensed pro for panel work

Electrical service changes demand permits, utility coordination, and tested installation practices. Choose a company with residential expertise, a documented warranty, and clear communication.

Frequently Asked Questions

Can I upgrade only the breaker box without changing the service?

Sometimes. If your service amperage is adequate and the meter and conductors are sized correctly, a panel-only replacement can add safer, modern breaker spaces.

How many amps should my home have?

Many modern homes run 150 to 200 amps. Homes with electric ranges, EV charging, or multiple HVAC systems often benefit from 200 amps or more.

Do I need surge protection with a new panel?

Yes. Since the 2020 NEC update, whole-home surge protection is required when installing new services or replacing panels in most jurisdictions.

Will power be off during a panel upgrade?

Yes. Expect several hours without power during the cutover. We plan the schedule to minimize downtime and restore power the same day in most cases.

How long does permitting and inspection take?

It varies by city and utility. We handle permits and coordinate with the utility. Most panel projects complete in one day, plus inspection timing.
