WHOLE-HOME SURGE PROTECTORS AT GUARANTEED SERVICE

Whole House Surge Protector Installation

At Guaranteed Service, our whole surge protector installation process is designed to be seamless and minimally disruptive. It starts with a careful check of your electric panel and home electrical system. We look at panel capacity, grounding quality, and the state of your circuit breakers. Next, we recommend a surge protective device (SPD) tailored to your needs, typically a Type 1 SPD rated for your service entrance and compliant with UL 1449 standards. For layered defense, we may suggest adding Type 3 plug-in units at key outlets.

On installation day, our licensed electricians will:

  1. Shut off power at the main breaker and verify zero voltage.
  2. Mount the SPD inside or adjacent to the panel and connect it to the grounding wire and neutral bus.
  3. Torque all connections to manufacturer specifications and reset breakers as needed.
  4. Restore power and test the SPD’s status indicator to confirm it will clamp dangerous spikes and divert them safely to ground.

The entire process typically takes 1-3 hours, depending on panel accessibility. If your panel is outdated or lacks proper grounding, we’ll discuss an electric panel upgrade to meet modern codes, ensuring your new whole house surge suppressor delivers reliable home surge protection.

  • What Are Whole Home Surge Protectors?

    A whole home surge protector (Type 2 SPD) is a device installed at your main service panel to defend against transient voltage spikes. Surges originate externally, from lightning strikes or utility switching, and internally, when motor-driven appliances cycle on. Positioned at the service entrance, the SPD continuously monitors incoming voltage and, upon detecting a spike above its clamping threshold (commonly around 600 V for 120 VAC systems), instantly diverts excess current into the grounding wire.


    Unlike plug-in power strips, a whole house power surge protector delivers centralized surge protection for every circuit. It works in tandem with your circuit breaker: while breakers trip on sustained overcurrent, SPDs clamp fast, microsecond-level spikes, preventing nuisance trips and preserving electronics. Many SPDs feature visual status indicators or alarms to signal when the internal module needs replacement after a significant surge.


    For the ultimate home surge protection, consider combining a panel-mounted SPD with Type 3 local protectors at high-value equipment points, ensuring maximum defense for servers, home theaters, and smart-home devices.


  • What Devices Need Surge Protectors?

    Surge protectors are capable of keeping all devices safe against power surges.


    The most important appliances you want to use with a surge protector are:

    • Televisions
    • Computers
    • Laptops
    • Gaming systems
    • Charging phones
    • Entertainment centers

    It's best to use surge protectors on high-end electronic devices that are expensive or difficult to replace. It necessary to use a surge protector on a light bulb because the worst thing that could happen during a power surge is that it would burn out. With high-end electronics, power surges can cause extensive damage or even destroy these appliances completely.

    • SPD Device: $100-$400, based on joule rating and brand.
    • Labor: $200-$500 for a standard whole surge protector installation by our licensed electricians.
    • Panel Upgrades: $300-$1,200 if your electric panel requires replacement or grounding improvements.
    • Permits & Inspections: Vary by jurisdiction, typically $50-$200.
    • Factors influencing cost:
    • Joule Rating: Higher ratings (e.g., 100 kA+) offer stronger defense against power surges.
    • Panel Type: Outdoor-rated SPDs or three-phase systems add materials and labor.
    • Local Codes: Permit fees and mandatory inspections can adjust the total investment.

Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.

Professional & Friendly

Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.

Whole Home Surge Protector FAQs

  • Do I really need a whole home surge protector?

    Yes. While point-of-use protectors guard individual devices, only a panel-mounted unit offers complete home surge protection, defending both your electronics and major appliances from internal and external voltage spikes.

  • Are whole house surge protectors better than power strips?

    Absolutely. Power strips can only handle minor fluctuations. A professional whole house surge suppressor installation clamps large transient spikes at the panel, shielding every circuit and reducing nuisance breaker trips.

  • How long do whole home surge protectors last?

    Most SPDs last 10-15 years under normal conditions. After a major surge event, internal components may degrade; we recommend having your unit inspected or replaced to maintain peak surge protection.

  • Where is a whole home surge protector installed?

    It’s wired directly into your main breaker panel or meter base, connecting to the grounding bus. Our electricians ensure compatibility with your electric panel, integrate with the circuit breaker, and comply with all electrical codes.

  • What appliances benefit most from surge protection?

    Sensitive electronics—computers, home theaters, smart-home hubs—are especially vulnerable. Major appliances (refrigerators, washers/dryers, HVAC systems) also benefit, making a whole house power surge protector a wise, long-term investment.
