Surge Protectors: Your Best Defense Against Storm-Induced Power Surges

Our licensed electricians are often asked about precautions that are needed during storms. One of the simplest and most effective solutions is using surge protectors. In this article, I’ll dive into why surge protectors are essential during storms, how they work, and how to choose the best one for your home.

What Causes Power Surges?

Power surges are sudden increases in voltage that can damage or destroy electronic devices. These surges can occur for several reasons, including lightning strikes, downed power lines, and the restoration of power after an outage. During storms, the risk of power surges increases significantly, making it crucial to protect your devices.

How Do Surge Protectors Work?

Surge protectors shield your electronic devices from voltage spikes by diverting excess electricity to the grounding wire. Here’s a breakdown of the key components and their roles:

  • Metal Oxide Varistor (MOV): The core component that absorbs excess voltage and directs it safely to the ground.
  • Grounding Wire: Provides a path for the excess voltage to be safely dissipated.
  • Indicator Lights: Show the status of the surge protector, indicating if it’s functioning correctly.

The Necessity of Surge Protectors During Storms

Lightning strikes can cause severe power surges that travel through power lines and into homes, potentially damaging anything plugged into an outlet. Surge protectors are designed to handle these spikes and prevent them from reaching your valuable electronics. By using surge protectors, you can avoid costly repairs or replacements and reduce the risk of fire.

Choosing the Right Surge Protector

Not all surge protectors offer the same level of protection. Here are some factors to consider when selecting one:

  1. Joule Rating: This measures the energy absorption capacity of the surge protector. For effective storm protection, look for a joule rating of at least 2,000.
  2. Clamping Voltage: The voltage level at which the surge protector activates to divert excess electricity. A lower clamping voltage offers better protection; aim for 400 volts or less.
  3. Response Time: The quicker the response time, the better the protection. Look for a response time of one nanosecond or less.
  4. Number of Outlets: Ensure the surge protector has enough outlets for all your essential devices.
  5. Additional Features: Some protectors come with USB ports, coaxial cable protection, or Ethernet protection, which can be beneficial for comprehensive protection.

Whole-House Surge Protectors

For the highest level of protection, consider installing a whole-house surge protector. These devices are connected directly to your electrical panel and protect all the circuits in your home. Although they are more expensive than plug-in products, they provide robust protection against large surges caused by lightning.

Installation Tips

Proper installation ensures your product work effectively:

  • Plug-In Surge Protectors: Simply plug them into an outlet and then connect your devices.
  • Whole-House Surge Protectors: These should be installed by a licensed electrician to ensure they are correctly connected to your electrical panel.

Maintenance and Replacement

Surge protectors degrade over time and need to be replaced periodically to ensure continued protection:

  • Indicator Lights: Pay attention to the indicator lights. If they go out, it’s time to replace the unit.
  • Regular Replacement: Even if the lights are functioning, replace surge protectors every 3-5 years or after a significant surge event.


Storms can cause significant damage to your home’s electrical system, but with the right hardware, you can protect your valuable electronics and appliances. Understanding how these products work and selecting the right ones for your needs will help keep your home safe during stormy weather.

What Causes Lights to Buzz?

When the serene ambiance of your home is disturbed by the persistent buzzing of lights, it’s not just an annoyance—it’s a symptom of underlying electrical issues that demand attention. This issue can have various causes, from simple solutions to complex electrical problems. Ensuring the safety and comfort of your home environment requires understanding the cause of buzzing lights. For professional diagnosis and repair, DFW Electrician & HVAC stands ready to assist. Here’s an in-depth look into the reasons behind buzzing lights and what actions you can take.

  1. Dimmer Switch Compatibility

One common cause of buzzing lights is the use of dimmer switches with non-compatible light bulbs. Dimmer switches work by rapidly turning the light circuit on and off to simulate lower light levels, which can cause an audible buzzing sound if the light bulb isn’t designed to handle this type of operation. LED bulbs, in particular, may require specific dimmer switches designed for low-power lighting to operate quietly and efficiently.

  1. Loose Connections on Lights

A loose electrical connection, either in the light fixture itself or in the wiring to the switch or outlet, can also lead to buzzing noises. These loose connections can cause a slight arcing of electricity, which generates a buzzing sound and potentially poses a fire risk. Ensuring all connections are tight and secure can often resolve this issue.

  1. Lights Overloaded Circuits

When too many devices or fixtures are connected to a circuit, it can cause lights to buzz due to strain on the electrical system. Overloading can increase the electrical current’s flow through the light bulb, leading to overheating and noise. Evaluating the load on your circuits and redistributing electrical devices can alleviate this problem.

  1. Transformer Issues

Certain types of light fixtures, especially low-voltage lighting like halogen or LED systems, use transformers to reduce the voltage supplied to the bulbs. A malfunctioning or incompatible transformer can create a buzzing sound in the lights it supplies. Replacing the transformer with one that matches the fixture’s voltage requirements can eliminate the noise.

  1. Lights Bulb Type and Quality

The type and quality of the bulb can also influence the presence of buzzing sounds. Cheaper, lower-quality bulbs may buzz more than higher-quality options due to inferior manufacturing standards. Additionally, fluorescent bulbs are more prone to buzzing, especially as they age or if they’re used with incompatible ballasts. Switching to high-quality, compatible bulbs often solves the buzzing issue.

  1. Electrical Interference

Electrical interference from nearby appliances or improperly shielded wiring can induce a buzzing sound in light fixtures. This is more common in environments with a high density of electrical devices. Identifying and relocating the source of interference, or upgrading wiring to include better shielding, can mitigate this problem.

  1. Harmonic Resonance

Sometimes, the buzzing isn’t due to the electrical system but rather a physical vibration in the light fixture, known as harmonic resonance. This occurs when certain parts of the light fixture vibrate in response to the electrical current. Adjusting the fixture or dampening the vibration with padding can reduce or eliminate the noise.


Buzzing lights are more than just a nuisance; they’re an indication that something in your electrical system may need attention. Whether it’s a compatibility issue with dimmer switches, a loose connection, or a more complex problem like electrical interference, addressing the root cause is essential for both peace of mind and safety. If troubleshooting your buzzing lights seems daunting, or if the problem persists, consulting with professionals like DFW Electrician & HVAC is a wise choice. Their expertise can help diagnose and fix the issue, ensuring your home remains a tranquil and safe environment. Regular maintenance and attention to the quality and compatibility of your electrical devices and fixtures can prevent buzzing lights and keep your home’s ambiance undisturbed.

Top 6 Common Electrical Problems

Electrical systems in homes are complex systems composed of many interconnected components. The wiring in walls, the circuit breakers, outlets, and electrical fixtures are enough to concern homeowners, but older homes could also have outdated wiring and materials. These are all common electrical problems  from flickering lights to a full-blown housefire, faulty components, electrical wiring, and old materials can cause problems.

The purpose of this article is to review some of the most common electrical problems that occur in homes.

When troubleshooting electrical problems, always exercise extreme caution. It is always advisable to hired licensed electrician to rewire switches, outlets, circuit breakers, junction boxes, and mounted electrical fixtures.

Outlets that are loose.

A receptacle or outlet’s contacts wear down over time, which makes it easier for plugs or cords to slip out. Not only is this a nuisance, but it is also quite dangerous. When a contact is loose, electricity can jump from one point to another, causing an arc. As dust, wood, and other in-wall debris can catch fire from an arc, arcing is a significant fire hazard.


The term “over-lamping” describes fitting a light fixture with a bulb with a higher wattage than its intended power. People often underestimate the danger of this. Hot bulbs can damage sockets and adjacent wiring in fixtures. As a result, arcing can occur, which in turn can cause a fire.

Absence of GFCIs.

A ground fault circuit interrupter (GFCI) outlet can detect minor changes in electrical current in an outlet. When human contact or water exposure occurs, the device can shut down the power. It is simply safer to use GFCI outlets than conventional outlets.

Coverless Junction Boxes.

High-voltage electrical wiring is connected through junction boxes. Despite the use of plastic clips and electrical tape, these splices pose a risk of electrocution.

Switches that are faulty.

There are a number of reasons why on/off and dimmable switches may fail. Possibly there is loose wiring, arcing, or the plastic pieces are worn out. Whatever the case may be, it is best to repair the switch to avoid a dangerous situation.

Panels that are over-wired.

Over-wiring occurs when a panel is wired to more circuits than it can handle. It can cause problems with your circuit breaker, or a problem with your fuse box in older homes.
