Surge Protection Services in Metro Atlanta

North Georgia weather brings more than just rain; it brings high-intensity lightning strikes that threaten your home’s electrical integrity. Metro Atlanta homeowners face unique risks from a volatile power grid, where voltage spikes occur during heavy storms or when local utility loads shift in crowded suburbs like Marietta or Decatur.

R.S. Andrews installs whole-home defense systems designed to withstand these specific regional challenges. We focus on shielding the heavy-duty compressors in your air conditioner and the delicate motherboards in your modern kitchen appliances from the “silent killers” of the Georgia power grid.

Indicators of Voltage Instability

Modern microprocessors are highly sensitive to even minor fluctuations. Your home likely requires a professional upgrade if you notice:

• Flickering Lights during storms or when your HVAC unit cycles on.

• Tripped Breakers occurring without an obvious overloaded circuit.

• Discolored Outlets or a persistent burning smell near electronic devices.

• Digital Failures on microwave clocks or smart appliance displays.

• Neighborhood Outages that result in “dirty power” surges when the grid is restored.

Surge protection helps hedge against these issues. Instead of allowing a power surge to course through your home, a surge protector will defend your electrical system and the devices connected to it. 

Whole-Home Surge Protection Installation

Precision Installation at the Source

True surge protection starts where power enters your home, not at your outlets. Our electricians install whole-home surge protection devices (SPDs) directly at your main electrical panel, stopping dangerous voltage spikes before they can reach your appliances, electronics, or wiring.

Type 1 & Type 2 Surge Protection Devices

We install both Type 1 and Type 2 SPDs depending on your system’s needs. These devices are designed to intercept high-energy surges caused by lightning strikes, utility switching, or grid disturbances, diverting that excess energy safely to ground before it can cause damage.

Grounding System Integrity

A surge protector is only as effective as the grounding system behind it. We perform a detailed inspection of your grounding electrode system, ensuring it provides a low-resistance path for excess voltage. If grounding is compromised, even the best surge protector will not perform correctly.

Soil & Environmental Considerations

In certain regions, soil composition can impact grounding performance over time. We evaluate environmental factors, such as corrosion-prone or mineral-heavy soil conditions, that may degrade grounding rods and reduce surge protection effectiveness. Where needed, we recommend corrective upgrades to maintain long-term reliability.

Code-Compliant Protection

All installations are completed in strict accordance with the latest National Electrical Code (NEC) standards. This ensures your system not only performs effectively but also meets safety requirements for proper energy dissipation and electrical system protection.

Repair & Maintenance Protocols

Electrical surges often leave behind “hidden” damage that compromises your safety over time. Our team will help determine if there is damage after a surge, and repair it, through one or more of the following 

• Diagnostic Testing: We evaluate the internal metal oxide varistors in your protector to ensure they still maintain the proper clamping voltage.

• Module Replacement: If your device shows a red warning light, our team replaces damaged modules to restore your defense layer.

• System Audits: We recommend a full audit every two years to ensure your protection matches your current electrical load, especially after adding EV chargers or smart home hubs.

• Tightening Connections: Maintenance visits include securing electrical terminations within the panel to prevent arcing and heat buildup.

Surge Protection for HVAC and Appliances

Your HVAC system and major appliances are some of the most expensive and sensitive components in your home. Modern systems rely on circuit boards, sensors, and motors that can be damaged by even minor voltage fluctuations. Air conditioners and heat pumps are especially vulnerable due to frequent cycling, which increases their exposure to surges over time.

Whole-home surge protection helps shield these systems by stopping excess voltage at the panel before it can reach your equipment. For added protection, dedicated surge devices can be installed for HVAC units and large appliances, helping reduce the risk of costly repairs, unexpected breakdowns, and premature system failure.
