New Braunfels electrical panel & service upgrades — what to pick

Estimated Read Time: 9 minutes

If your lights dim, breakers trip, or new appliances strain your system, an electrical service upgrade is likely due. The right electrical service upgrade boosts safety, capacity, and reliability so your home can handle HVAC, EV charging, and smart tech. In San Antonio and Houston, our licensed team helps you size and plan an upgrade that fits your goals. Ask about our current free surge protector offer.

What is an Electrical Service Upgrade?

An electrical service upgrade increases the total amperage feeding your home and modernizes the main equipment that manages power. It often includes new service conductors, meter base, main disconnect, grounding and bonding, and a new or larger main panel.

Most older homes were built with 60 or 100 amps. Today’s homes with central HVAC, induction cooking, and EV charging often need 200 amps or more. Upgrading the service protects your home from overloads, nuisance tripping, and overheating conductors.

Texas cities enforce the National Electrical Code through local permits and inspections. In San Antonio and Houston, that means the work is reviewed and approved before final energizing. The result is a safer, more reliable electrical system that supports your lifestyle.

Signs You Need More Capacity

Consider an upgrade if you notice any of the following:

1. Breakers trip regularly or will not reset.
2. The panel is warm to the touch or smells like burning.
3. You recently added high demand loads like an EV charger, hot tub, or large HVAC.
4. You still use fuses or have a 100 amp panel.
5. You plan a remodel or addition that adds circuits or square footage.

Other clues include frequent dimming when major appliances start, limited open breaker spaces, or visible corrosion. A licensed electrician can perform a load calculation and inspect grounding, bonding, and service equipment to confirm the need and the right size.

Panel Upgrade vs. Full Service Upgrade

These terms sound similar but they are not always the same. Knowing the difference helps you choose what fits your home and budget.

1. Panel Upgrade

   • Replaces the main distribution panel or subpanel.
   • Adds safer breakers and more spaces for circuits.
   • Capacity may or may not increase depending on the service size.

2. Service Upgrade

   • Increases total amperage to the house. Typical jump is 100 to 200 amps.
   • May require new service entrance conductors, meter base, main disconnect, grounding, and a larger main breaker.
   • Often paired with a new main panel for a complete modernization.

If your issue is only lack of breaker spaces, a panel swap could be enough. If you are adding an EV charger or second HVAC system, a full service upgrade is usually the right answer.

How to Right-Size Your Upgrade

Choosing the correct amperage avoids overspending while preventing future headaches. Sizing is based on a calculated load, not guesswork.

Steps your electrician will take:

1. Inventory major appliances and fixed loads like HVAC, cooktop, oven, water heater, dryer, EV charger, hot tub, and well pump.
2. Apply standard demand factors to reflect real world use.
3. Consider square footage and general lighting loads.
4. Factor in future plans such as an addition or solar with battery storage.

Common choices:

• 150 amps for smaller homes with gas heat and modest electric loads.
• 200 amps for most modern homes with central HVAC and an EV charger.
• 300 to 400 amps for large homes, dual HVAC systems, or multiple EVs.

Your design should leave headroom. That way you avoid another upgrade when your next appliance or vehicle arrives.

What the Process Looks Like in San Antonio and Houston

Every property is a little different, so expect a tailored plan. Here is the typical path homeowners follow with our team.

1. Site Evaluation and Load Calc

   • We assess the current panel, meter, grounding, and service entrance. We listen to your goals and perform a load calculation.

2. Clear Recommendations and Pricing

   • You receive options that match your needs and budget. Transparent line items cover equipment, permits, and utility coordination.

3. Permits and Utility Coordination

   • We handle permit submission and schedule the utility. In San Antonio we coordinate with CPS Energy. In Houston we work with CenterPoint Energy.

4. Scheduled Installation Day

   • Power is shut off while we work. Crews replace equipment, update grounding and bonding, and label circuits. Most projects finish the same day.

5. Inspection and Re-energizing

   • The city inspects the work. After approval, the utility returns power and we walk you through the new equipment and warranty.

You receive a written summary and recommendations, including maintenance tips to protect your investment.

Safety, Code, and Compliance Basics

Electricity is unforgiving. The right electrical service upgrade should improve safety as much as capacity.

Key safety elements include:

• Proper grounding and bonding that meets current standards.
• Correct conductor sizes for the new service amperage.
• Secure, listed meter base and service disconnect equipment.
• Correctly sized main breaker and short circuit ratings.
• Arc fault and ground fault protection in required areas when circuits are extended or added.

Texas cities require permits and inspections for service work. This protects homeowners from hidden risks like undersized conductors or loose terminations that can overheat.

Cost Factors and How to Control Them

No two homes are the same, so pricing varies. These items influence your total cost.

1. Service Size and Equipment Brand

   • 150 amp vs 200 amp vs 400 amp equipment and the type of panelboard and breakers.

2. Meter and Mast Upgrades

   • Overhead or underground service, mast height, and meter base requirements.

3. Relocation or Obstructions

   • Moving a panel to meet clearance rules or working around masonry, cabinetry, or tight spaces.

4. Grounding and Bonding Corrections

   • New ground rods, water bond, and service bonding jumpers.

5. Add-ons and Protections

   • Whole home surge protection, dedicated circuits, or energy monitoring.

Ways to save without cutting corners:

• Bundle a panel upgrade with your service upgrade to reduce labor duplication.
• Use financing to spread out costs while you enjoy the benefits now.
• Join our membership for ongoing inspections that prevent costly surprises.

Smart Add-ons That Protect Your Investment

Several upgrades pair well with a new panel or service. They reduce risk and improve convenience.

• Whole Home Surge Protection

  • Protects electronics and HVAC during utility events and lightning. We currently include a free surge protector with any panel or full electrical service upgrade for a limited time.

• Dedicated Circuits

  • Support EV chargers, home offices, or workshop tools without nuisance trips.

• Energy Monitoring

  • Track real time usage and find waste. Great for identifying problem appliances.

• Voltage Regulation

  • Stabilizes sensitive equipment in neighborhoods with fluctuating voltage.

Ask your electrician which options deliver the best value for your home and goals.

Preparing Your Home for Installation Day

A little prep helps the day go smoothly and shortens downtime.

• Clear a 3 foot area in front of the panel and meter location.
• Unplug sensitive electronics or use quality surge strips until the new protector is installed.
• Plan for limited power during the changeover. Most projects complete the same day.
• Notify household members about the schedule, including Wi Fi and garage door impact.
• Keep pets secured and pathways open for technicians and ladders.

We stock common parts to keep work moving and reduce delays. If a surprise pops up, you will get clear options before we proceed.

How to Compare Contractors and Proposals

A low price that cuts safety steps can cost more later. Use this quick checklist when reviewing bids.

1. Licensing and Insurance

   • Verify Texas electrical licensing. Elmer’s lists TDLR #40048. Ask for proof of liability coverage.

2. Detailed Scope

   • Load calculation, permit handling, utility coordination, and inspection support should be included.

3. Equipment and Ratings

   • Brand, service size, breaker type, and short circuit ratings should be clear and appropriate for your home.

4. Grounding and Bonding

   • Ensure upgrades to meet current standards, not just a panel swap.

5. Warranty and Guarantees

   • Look for strong workmanship warranties and a satisfaction guarantee.

6. Schedule and Downtime

   • Clarify expected start and finish times and what to expect while power is off.

7. Add ons and Value

   • Consider surge protection and energy monitoring while the panel is open. Ask about promotions.

Choose the team that communicates clearly, stands behind their work, and treats your home with respect.

Frequently Asked Questions

How do I know if I need 200 amps or more?

A licensed electrician performs a load calculation of all fixed appliances and general lighting. Most modern homes with central HVAC and an EV charger land at 200 amps. Large homes or multiple EVs may need 300 to 400 amps.

How long does a service upgrade take?

Most upgrades are completed in one day once permits and utility coordination are set. Expect power to be off during installation, with the city inspecting before re energizing.

Do I need a permit for an electrical service upgrade?

Yes. Cities in Texas require permits and inspections for service equipment changes. Your contractor should file, schedule inspections, and coordinate with the utility.

Will a new panel stop my breakers from tripping?

If tripping is due to overloads or weak breakers, a panel and service upgrade helps. If a circuit fault exists, it must be corrected during the upgrade to stop future trips.
