Power Surge Protection

Surge Protection Can Be The Best Investment You Can Make To Your Home Or Property

Our homes and properties are full of expensive appliances and electronics such as computers, refrigerators, stoves, dishwashers, washing machines, televisions, stereos and more.

One power surge, and one or all of these important items may need to be replaced. Costing us thousands in replacement costs.

The Facts

A power surge may last for only less than a second, but at its worst, it carries tens of thousands of volts, which in turn can crash your hard drive, and render your television or home entertainment system useless.

As we are heading into the summer months, we most likely will be hit with many thunderstorms. Lightning-induced surges are the most powerful and most scary: A 200,000-amp jolt crashing through a power line will burn standard 20-amp wiring like a lightbulb filament. Lightning can be dangerous even if it doesn’t strike right at your home, it can still do damage if striking a half mile away.

The most common surges are caused by downed power wires, sudden changes in electricity use by a nearby business, or even a defective fan or hairdryer in your home. These surges can cause damage to your valuable electronics, appliances and many other items.

The Myth

Many homeowners believe adequate surge protection can be solved with plugging their electronics into a power strip. Unfortunately, that is not enough protection. First of all, not all surge protectors live up to their name; some are little more than just an extension cord. Second, a surge will follow any wire into a home including phone and cable wires and jeopardize dsl lines, phones, televisions, your satellite systems, computers, and more. These “plugged in surge protectors” cannot protect against large power strikes affecting the whole house.

The Solution

Guarding against surges requires two approaches: a whole-house suppressor to help with the big, dangerous power strikes and an individual plug in surge suppressor for your most expensive and delicate appliances and electronic devices. Both types regulate the flow of the electrical current. Normally they just sit there, allowing electric current to flow through them. But when higher-than-normal voltage occurs the devices instantly sends the excess voltage to the grounded wire. As soon as voltage levels return to normal, the flow of electricity is restored.

Typically, whole-house suppressors are hard-wired to the service panel, a process that takes a licensed electrician about two hours. Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Separate but smaller whole-house units are recommended for the phone and cable lines. These protect telephone, televisions, and modems.

How Whole-Home Surge Protection Works

Whole-home surge protectors are installed directly at your electrical panel to stop excess voltage before it reaches your wiring, outlets, or connected equipment. When a surge occurs, the system safely redirects excess electricity into the ground, protecting your entire home at once.

This proactive protection is far more effective than relying on individual power strips, which only protect select outlets and cannot stop large external surges.

Reasons to Install Whole-Home Surge Protection in Maryland

Maryland homeowners face unique electrical risks due to frequent thunderstorms, aging electrical infrastructure, and increasing household power demands. Even small, repeated surges can quietly damage electronics and appliances over time.

Common reasons Maryland homeowners choose whole-home surge protection include:

• Frequent summer storms and lightning activity

• Power grid switching and utility fluctuations

• Homes with HVAC systems, heat pumps, or smart thermostats

• Home offices with computers and networking equipment

• EV chargers and high-demand modern appliances

Without whole-home protection, your electrical system remains vulnerable every time voltage spikes enter your home.

Why Maryland Homes Need Whole-Home Surge Protection

Maryland’s seasonal storms, dense neighborhoods, and aging power infrastructure increase the risk of electrical surges year-round. Homes with modern appliances, home offices, EV chargers, and smart technology are especially vulnerable to voltage spikes that can cause immediate or long-term damage.

Whole-home surge protection provides a first line of defense at your electrical panel, helping prevent damage before excess voltage reaches your wiring, HVAC system, or connected devices. This added layer of protection is especially valuable for Maryland homeowners looking to protect their investment and avoid unexpected electrical failures.

Long-Term Benefits of Whole-Home Surge Protection

Whole-home surge protection is not just about preventing immediate damage. It also helps preserve the performance and lifespan of your electrical system and major investments.

Benefits for Maryland homeowners include:

• Reduced wear and tear on appliances and electronics

• Protection for HVAC systems, electrical panels, and wiring

• Fewer unexpected repair and replacement costs

• Improved electrical system reliability

• Added home value and long-term peace of mind

Professional installation ensures your surge protection system is properly grounded, sized, and fully compliant with Maryland electrical codes.
