Whole-Home Surge Protection Installation
Modern homes are filled with sensitive microprocessors. Computers, smart TVs, home automation systems, kitchen appliances, and EV chargers are vulnerable to voltage fluctuations. While power strips provide localized protection, they cannot handle larger grid anomalies.
At Mills Electric Co, we install panel-mounted Type 2 Surge Protective Devices (SPDs) that protect every circuit in your home. This ensures that transient voltages are intercepted and safely diverted to ground before reaching your appliances.
Internal vs. External Surges
Many homeowners believe that surges are only caused by lightning strikes. However:
- External Surges (20%): Caused by lightning strikes, utility grid switching, or downed power lines. These are highly destructive and can destroy unshielded equipment instantly.
- Internal Surges (80%): Generated inside your own home when high-draw motors (such as the HVAC compressor, well pump, clothes dryer, or refrigerator) kick on and off. These minor spikes occur multiple times a day. While they rarely cause immediate failure, they slowly degrade the sensitive microchips in your electronics over time, shortening their lifespan.
The Role of Your Grounding System
A surge protection device is only as effective as the ground it connects to. When a voltage spike occurs, the SPD dumps the excess voltage down your ground wire. If your home’s ground rods are corroded, loose, or improperly installed, the surge has nowhere to go.
During every whole-home surge protector installation, Mills Electric Co inspects your electrical grounding system. We verify the connections to your copper ground rods and cold water pipe ties to ensure a low-impedance path to the earth.
Surge Protection Costs & Warranty
Installing a premium, panel-mounted surge protector is an affordable way to safeguard thousands of dollars in household electronics. We provide flat-rate upfront quotes for all installations:
- We install Type 2 SPDs directly into your main electrical panel or via an external mounting nipple if space is limited.
- We handle any municipal permits if required (permitting fees range from $50 to $500 depending on county regulations).
Every installation is backed by our standard 1-Year Workmanship Warranty. For long-term peace of mind, we offer an Extended Workmanship Warranty for 10% of the project cost per year, up to 5 years, which covers all diagnostic and labor service call fees.

Do I need a licensed electrician for whole home surge protection?
Yes, electrical work should be handled by a qualified licensed electrician when safety, wiring, panels, circuits, or permanent installation are involved. Mills Electric Co. is licensed under Electrical License #36565 and carries insurance through biBerk Policy #N9BP158903. A licensed contractor can also help you avoid unsafe shortcuts that may create problems later.
How do I know if I need whole home surge protection or a different electrical service?
You do not have to diagnose it before calling. Explain what you are seeing, hearing, smelling, or planning. Mills Electric Co. will look at the affected circuit, panel, device, or fixture and recommend the service that actually matches the issue.
Can Mills Electric Co. provide a price before starting?
For many jobs, pricing can be discussed after the scope is reviewed. Electrical pricing depends on access, materials, panel condition, circuit length, device type, and safety requirements. The goal is to be clear before the work moves forward, not surprise you at the end.
Is whole home surge protection covered by a warranty?
Mills Electric Co. provides a 1 year workmanship warranty. Extended workmanship warranty coverage is available at 10% of the job cost per additional year, up to 5 years. Product warranties may depend on the manufacturer.
Can this be scheduled outside normal business hours?
Some service can be planned around access needs, and urgent issues may fall under emergency service. If the situation involves sparking, burning smells, heat at the panel, exposed live wiring, or power loss affecting safety, call (704) 818-7867.
Will the work be explained before anything is replaced?
Yes. Raymond Mills believes customers should understand the reason behind the recommendation. When troubleshooting or inspecting, the goal is to identify the cause before replacing parts that may not solve the problem.
