Surge Protection

The ERCOT grid operates independently from the US national grid. Texas homes see more frequent voltage transients than most of the country. Texas lightning is not hypothetical.

One Strike Shouldn’t Cost You Everything

Protect the Whole Home at the Panel

The ERCOT grid and frequent Texas lightning send voltage spikes through your wiring — and your A/C makes its own every time it cycles.

A Type 2 panel-mounted SPD protects everything downstream: HVAC, EV charger, appliances, and electronics. Installed in under two hours.

Why New Braunfels Homes Need This More Than Most

Two things make New Braunfels homes more vulnerable to surge damage than most of the country. First: the ERCOT grid operates independently from the US national grid and experiences more frequent voltage fluctuations during extreme weather and grid stress events. Second: Texas ranks in the top 5 states for annual lightning strikes, and Comal County's open terrain offers minimal protection. A direct hit isn't required — a strike on nearby power lines injects thousands of volts into the grid in milliseconds.

What Causes Power Surges in New Braunfels Homes

HVAC Cycling (~50% of damage)

Every time your A/C compressor starts or stops — which happens dozens of times per day in a New Braunfels summer — it creates a voltage spike on your home's circuits. Over time, these internal surges degrade sensitive electronics and appliance control boards. Your HVAC system is both a major source and the most expensive victim.

Lightning Strikes (~20% of damage)

A lightning strike on a power line injects thousands of volts into the grid in milliseconds. A direct hit on your home doesn't need to happen — a strike within a mile can reach your electronics through the utility connection.

Generator Startup & Load Transfer

Generac generators produce voltage spikes during startup and during transfer switch events — both when switching to generator power and when switching back to grid power. If you have a generator, you specifically need surge protection for this reason.

ERCOT Grid Events

Power restoration after outages and load switching during grid stress events create transient voltage spikes throughout the distribution system. Post-storm power-on events are some of the most common surge damage events in Comal County.

Large Motor Starts (~30% of damage)

Refrigerators, washing machines, and pool pumps create voltage spikes on startup. These are internal surges — they happen every day, don't trigger a surge protector reset, and accumulate damage over time.

Understanding Surge Protection Types

Type 2 — What Moorhead Installs

Hard-wired directly into your main electrical panel after the main breaker. Protects all circuits in the home simultaneously. This is the standard residential installation and is required by NEC 2020+ for new construction. One device protects everything — your HVAC, EV charger, refrigerator, smart home systems, and every appliance on every circuit.

Type 1 — Service Entrance (Rare)

Installed before the main breaker at the service entrance. Only required with dedicated lightning protection systems. Rare in residential applications.

Type 3 — Outlet Level (Secondary Only)

Outlet-level protection for specific devices — adds a secondary layer but cannot replace Type 2 panel protection. A power strip surge protector is Type 3.

What Gets Protected

  • HVAC and air conditioning system — The most expensive item in most New Braunfels homes, vulnerable to control board and motor damage from both external and internal surges
  • EV charger and vehicle on-board charger — The on-board charger in your Tesla, F-150 Lightning, or other EV is one of the most sensitive and expensive components in the vehicle
  • Smart home and electronics — Smart TVs, computers, home theater, thermostats, gaming systems — modern homes have $10,000+ in electronics on their circuits
  • Major appliances — Refrigerators, washers, dryers with electronic control boards cost $300–$800 to repair after surge damage
  • Generac generator — Generator control boards are expensive and surge-vulnerable at the transfer switch moment
  • Home office and network equipment — Computers, monitors, NAS drives, and network switches representing significant investment

Common Questions

Type 2 surge protector installed at your panel: $250–$375 for 50kA standard protection. $325–$450 for 80–100kA (recommended for homes with generators or EV chargers). Flat-rate, written, done in under 2 hours.
A power strip protects only devices plugged into it. A Type 2 panel-mounted SPD protects your entire home — including hardwired appliances like your HVAC, EV charger, and every device on every circuit simultaneously.
Yes, especially with a generator. Generators produce voltage spikes during startup and during transfer switch events. They're also at risk when grid power is restored. A Type 2 SPD with at least 80kA is strongly recommended for generator homes.
50kA minimum for standard homes. 80–100kA for homes with generators, EV chargers, home offices, or medical devices. High-lightning areas should consider 100kA+ devices. We recommend the right rating during the free panel assessment.
Two reasons: ERCOT operates independently from the national grid and experiences more frequent voltage fluctuations during extreme weather and grid stress events. And Texas ranks among the top 5 states for annual lightning strikes — Comal County's open terrain offers minimal natural protection.
Most Type 2 SPDs last 3–10 years depending on surges absorbed. LED indicators on quality devices signal depleted protection. Recommend replacing any unit older than 5 years if status hasn't been verified.
Yes. Many carriers offer 1–5% annual premium discounts for professionally installed whole-home surge protection. We provide documentation for your insurance filing.
Yes. Type 2 SPD protects your A/C control boards and motors from both external lightning surges and the internal cycling surges your own HVAC creates dozens of times per day. HVAC control board replacement runs $400–$900. The SPD is $250–$450. The math is obvious.
