Power surges in August in San Antonio can bring intense heat, sudden thunderstorms, lightning, power interruptions, and increased demand on residential electrical systems. Between appliances working harder, pool equipment running regularly, home offices staying powered, and families using more electronics, your home’s electrical system may already be under considerable strain.
Add an August thunderstorm or unexpected utility disruption, and your property could be exposed to a damaging power surge.
Power surges can happen in an instant, but the damage they cause may affect appliances, electronics, security equipment, smart-home devices, pool systems, and other valuable electrical components. Although no protection system can prevent every possible electrical loss, professionally installed whole-home surge protection can provide an important layer of defense.
Jireh Electric helps homeowners and businesses throughout Greater San Antonio and South Texas protect their properties with whole-home surge protection, electrical-panel evaluations, troubleshooting, repairs, dedicated circuits, and other professional electrical services.
Jireh Electric is locally owned and operated by Master Electrician Israel Vargas. When you need knowledgeable service from a trusted local electrical company, our team is ready to help.
What Is a Power Surge?
A power surge is a sudden increase in the voltage moving through an electrical system. Your home’s wiring, outlets, appliances, and electronics are designed to operate within a particular voltage range. When voltage rises unexpectedly, it can place stress on electrical components.
Some surges are brief and immediately destructive. Others are smaller and may gradually affect sensitive electronics over time.
A major surge can damage equipment instantly. A smaller surge might not produce an obvious problem right away, but repeated voltage fluctuations can contribute to premature equipment failure.
That is one reason homeowners may not always connect a damaged television, refrigerator, computer, or smart appliance to an earlier electrical event.
Lightning Is Not the Only Cause of Power Surges
Lightning is one of the most recognizable causes of electrical surges, especially during summer thunderstorms. However, a direct lightning strike is not required for a home to experience an electrical disturbance.
Power surges may also be associated with:
- Nearby lightning activity
- Utility equipment switching
- Power outages and service restoration
- Damaged electrical lines
- Problems with transformers
- Large appliances cycling on and off
- Faulty wiring or loose electrical connections
- Electrical equipment within the home
- Generator or transfer-equipment problems
- Aging electrical components
When power is restored after an outage, several appliances and systems may attempt to restart at the same time. This sudden change can place additional demand on the electrical system.
The source of a surge is not always obvious. That is why a broader electrical-protection strategy is often more effective than relying only on a few basic power strips.
What Can a Power Surge Damage?
Modern homes contain more sensitive electronics than ever before. Even appliances that seem primarily mechanical often contain electronic controls, circuit boards, digital displays, sensors, or wireless technology.
A power surge may affect:
- Televisions
- Desktop computers and laptops
- Wi-Fi routers and networking equipment
- Refrigerators and freezers
- Washers and dryers
- Ovens and ranges
- Dishwashers
- Home entertainment systems
- Security cameras and alarm systems
- Smart thermostats
- Smart lighting and home-automation equipment
- Garage-door openers
- EV charging equipment
- Pool pumps and control systems
- Hot tubs and spas
- Medical or accessibility equipment
- Office equipment
- Commercial machinery and electronics
Replacing several damaged devices at once can be expensive. The disruption can be even more serious when a surge affects refrigeration, security equipment, internet service, business systems, or essential home equipment.
Are Power Strips Enough to Protect Your Home?
Many homeowners use power strips for computers, televisions, and entertainment equipment. However, not every power strip provides surge protection. Some simply provide additional outlets.
Even a quality plug-in surge protector is designed to protect only the equipment connected to it. It does not protect hardwired systems or every circuit in the home.
Devices that may not be protected by ordinary power strips include:
- Major kitchen appliances
- Pool and spa equipment
- Garage-door openers
- Hardwired lighting
- Security systems
- Electrical panels and branch circuits
- Smart-home equipment installed throughout the property
- Other permanently connected systems
Plug-in surge protectors can still be useful as a second layer of protection for individual electronics. However, they should not be confused with whole-home surge protection installed at the electrical panel.
How Whole-Home Surge Protection Works
A whole-home surge protective device is typically installed at or near the main electrical panel. Its purpose is to help divert excess voltage away from the home’s electrical system before that voltage reaches connected equipment.
Think of it as a first line of defense for the entire property.
Whole-home surge protection can help protect multiple circuits and devices at the same time, including equipment that cannot be connected to a power strip.
For stronger protection, homeowners may choose a layered approach that includes:
- Professionally installed whole-home surge protection
- Quality point-of-use surge protectors for sensitive electronics
- Proper grounding and bonding
- A well-maintained electrical panel
- Prompt repair of damaged or loose wiring
- Safe practices during severe thunderstorms and outages
Surge protection is not a guarantee against every type of electrical damage. A severe or direct lightning event can overwhelm protective equipment. However, our professionally installed surge protection can help reduce the risk created by many common voltage spikes.
Why Proper Installation Matters
A surge protection device must be correctly selected, installed, and connected to the electrical system. The condition of the panel, available space, grounding, wiring, and electrical service all affect the installation.
This is not a project homeowners should attempt inside an electrical panel.
Even after individual breakers are switched off, parts of the panel may remain energized. Contact with energized components can cause serious injury, electric shock, burns, or death.
Our licensed electricians can:
- Inspect the electrical panel
- Evaluate the existing service
- Check grounding and bonding
- Select an appropriate surge protective device
- Install the device correctly
- Identify visible panel damage
- Look for overheating or loose connections
- Recommend repairs or upgrades when necessary
Jireh Electric provides professional surge-protection installation for homes and businesses throughout the San Antonio area.
Can an Older Electrical Panel Affect Your Protection?
Whole-home surge protection is only one part of a safe and dependable electrical system. If the electrical panel is outdated, damaged, corroded, overloaded, or improperly installed, additional work may be needed.
Warning signs of a potential panel problem include:
- Breakers that trip repeatedly
- Lights that flicker or dim
- Buzzing or crackling sounds
- A burning or melted-plastic odor
- Warm or hot panel surfaces
- Discoloration around breakers
- Visible rust or moisture
- Sparks from the panel
- Breakers that will not reset
- Frequently blown fuses
- A lack of space for necessary circuits
- An older system that no longer supports the property’s needs
Do not remove the panel cover or attempt to tighten internal electrical connections yourself.
When a panel makes unusual sounds, smells hot, shows signs of burning, or produces sparks, professional attention is needed promptly.
Why August Can Be Hard on Your Electrical System
The extreme summer heat can lead to greater household power consumption. At the same time, August storms may create lightning, outages, and utility fluctuations.
Your electrical panel may be supplying power to:
- Air-conditioning equipment
- Refrigerators and freezers
- Ceiling and portable fans
- Pool pumps
- Hot tubs
- Outdoor kitchens
- Landscape lighting
- Home offices
- Gaming and entertainment equipment
- EV chargers
- Workshops
- Additional refrigerators
- Smart-home devices
Each item may operate normally on its own. Problems can occur when several high-demand devices operate simultaneously, particularly in older homes with limited electrical capacity.
An electrical panel evaluation can help determine whether the system is adequately supporting the property’s current power needs.
Warning Signs After a Storm or Power Outage
Some electrical problems become noticeable only after severe weather or a utility interruption.
After a storm or outage, watch for:
- Electronics that no longer turn on
- Appliances behaving unpredictably
- Lights that are unusually bright or dim
- New buzzing sounds
- Breakers that trip repeatedly
- Outlets that feel warm
- A burning odor
- Flickering throughout several rooms
- Damaged plugs or power strips
- Smart devices that frequently disconnect
- Pool or spa equipment that no longer operates correctly
- A surge protector showing a warning or failed-protection light
Do not repeatedly reset a breaker that continues to trip. The breaker may be responding to an overload, short circuit, ground fault, damaged equipment, or another electrical problem.
Repeatedly forcing the circuit back on without identifying the cause can be unsafe.
What Should You Do During a Thunderstorm?
When thunderstorms approach, personal safety comes first. Move indoors when you hear thunder and avoid contact with outdoor electrical equipment, pools, hot tubs, metal fencing, and other conductive surfaces.
When practical and safe, unplug sensitive electronics before the storm arrives. Do not unplug equipment during active lightning if doing so would put you at risk.
During an outage:
- Use flashlights rather than candles
- Keep refrigerators and freezers closed
- Unplug sensitive electronics when it is safe
- Avoid damaged electrical lines
- Never touch a downed power line
- Keep generators outdoors and away from windows and doors
- Never connect a portable generator directly to household wiring without approved transfer equipment
- Report utility hazards to the appropriate provider
- Call emergency services when there is smoke, fire, or an immediate danger
If you smell burning, see sparks, or notice smoke from electrical equipment, leave the affected area and contact emergency services.
