Modern Phoenix homes depend on electronics for almost everything. From televisions and computers to smart home devices, appliances, security systems, and networking equipment, homeowners may have thousands of dollars invested in sensitive electrical equipment.
Power surges can happen when there is a sudden increase in electrical voltage. Lightning, utility problems, equipment failures, and power restoration after an outage can all contribute to electrical spikes.
Phoenix homeowners should take power surge protection seriously, especially during monsoon season and severe weather. The City of Phoenix recommends using surge protectors for electronics and advises residents to unplug unnecessary equipment when appropriate during severe weather.
Fortunately, there are several ways to reduce the risk of damage to your home’s electronics. From quality point-of-use surge protectors to whole-home surge protection, the right approach can provide an additional layer of protection.
What Is a Power Surge?
A power surge is a brief increase in electrical voltage within a home’s electrical system.
A surge can last only a fraction of a second, but sensitive electronics may be affected by excessive voltage.
Power surges can potentially damage components inside:
- Televisions
- Computers and laptops
- Gaming systems
- Refrigerators
- Washing machines
- Smart home equipment
- Wi-Fi routers
- Security systems
- Home theater equipment
- HVAC controls
- Appliances with electronic control boards
Some surge damage is immediately noticeable, while other damage may shorten the life of an electronic device.
What Causes Power Surges in Phoenix?
Power surges can have several causes. They do not always originate inside your home.
Potential sources include:
- Lightning strikes
- Utility system problems
- Power outages
- Power restoration
- Electrical equipment failures
- Large appliances switching on or off
- Problems with electrical wiring
- Storm-related electrical disruptions
Phoenix experiences monsoon storms and other severe weather conditions that can contribute to electrical service interruptions and lightning-related risks.
Because power interruptions can happen unexpectedly, homeowners should consider surge protection before a problem occurs.
Why Are Phoenix Homes at Risk During Monsoon Season?
Monsoon storms can bring lightning, strong winds, dust, heavy rain, and electrical service interruptions.
Lightning does not have to strike your home directly to create electrical problems. Nearby lightning activity can create dangerous electrical conditions.
Power can also be interrupted during severe weather. When electricity returns, electrical equipment can experience a spike or fluctuation.
APS recommends turning off and unplugging electronics and appliances during outages to help avoid electrical spikes when power is restored.
What Is a Surge Protector?
A surge protector is a device designed to help protect connected electrical equipment from voltage spikes.
Basic surge protectors are commonly used for individual electronics.
For example, a homeowner might connect a:
- Television
- Computer
- Gaming console
- Home theater system
- Wi-Fi router
- Desktop computer
to a quality surge-protection device.
However, not all power strips provide the same level of surge protection. Homeowners should choose properly rated equipment rather than assuming every power strip offers meaningful protection.
What Is Whole-Home Surge Protection?
Whole-home surge protection is installed as part of the home’s electrical system and is designed to help protect multiple circuits and connected equipment from certain electrical surges.
Unlike a plug-in surge protector that protects individual devices, a whole-home surge protective device can provide protection at the electrical service or panel level.
Whole-home surge protection can be especially useful for homeowners who have many expensive electronic devices throughout the property.
An electrician can evaluate your electrical panel and determine whether a whole-home surge protection system is appropriate for your home.
Why Should You Consider Whole-Home Surge Protection?
Modern homes contain more electronics than ever before.
A homeowner may have:
- Multiple televisions
- Computers
- Smart thermostats
- Security cameras
- Smart locks
- Wi-Fi equipment
- Appliances with electronic controls
- Pool equipment
- Garage door openers
- Home automation systems
Protecting individual devices with plug-in surge protectors can help, but it may not provide protection for every connected system.
Whole-home surge protection can provide an additional layer of protection for your home’s electrical system.
Can a Surge Damage Your Appliances?
Yes. Many modern appliances contain electronic control boards and other sensitive components.
A refrigerator, washing machine, dishwasher, oven, or HVAC system may contain electronics that can be affected by electrical problems.
Surge protection does not guarantee that equipment will never be damaged. However, properly selected and installed protection can help reduce exposure to certain electrical surges.
This is particularly important when replacing older appliances with newer models that contain more electronic controls.
Signs Your Home May Need Better Surge Protection
You may want to consider improving your home’s surge protection if:
- You have expensive electronics throughout your home
- Your home frequently experiences power interruptions
- You live in an area affected by severe storms
- Your electronics have experienced unexplained failures
- You have recently invested in smart home equipment
- You have a home theater system
- You work from home using computers and networking equipment
- You are remodeling or upgrading your electrical system
If you are unsure about the level of protection your home currently has, an electrician can inspect the electrical panel and discuss available options.
Should You Use Plug-In Surge Protectors?
Plug-in surge protectors can still be useful for sensitive electronics.
They are particularly helpful for equipment such as:
- Computers
- Televisions
- Gaming systems
- Routers
- Home theater equipment
- Office electronics
However, plug-in protection should not necessarily be viewed as a replacement for whole-home surge protection.
A layered approach can provide protection at different points in the electrical system.
What About Uninterruptible Power Supplies?
An uninterruptible power supply, or UPS, can be useful for certain electronics that need temporary backup power.
A UPS may be helpful for:
- Computers
- Networking equipment
- Security systems
- Home office equipment
- Certain communication devices
A UPS can provide battery backup during an outage and may also provide power conditioning or surge protection depending on the equipment.
For critical electronics, homeowners should consider both surge protection and appropriate backup-power options.
Should You Unplug Electronics During a Storm?
Unplugging unnecessary electronics during severe weather can reduce their exposure to electrical problems.
The City of Phoenix recommends using surge protectors for electronics during lightning-related risks, while APS advises customers to unplug unnecessary equipment and appliances to help prevent electrical spikes when power is restored.
However, never attempt to unplug equipment if doing so would require contact with wet electrical equipment or unsafe conditions.
Electrical safety should always come first.
Protecting Smart Home Electronics
Smart home technology has become increasingly common in Phoenix homes.
Examples include:
- Smart thermostats
- Security cameras
- Video doorbells
- Smart locks
- Smart lighting
- Wi-Fi routers
- Home automation hubs
- Smart appliances
Because many of these devices remain connected to your home’s electrical and communication systems, homeowners should consider how surge protection fits into their overall electrical plan.
Protecting Your Home Office
If you work from home, electrical protection becomes even more important.
A power surge could potentially affect:
- Computers
- Monitors
- Printers
- Routers
- Modems
- External hard drives
- Networking equipment
A combination of quality surge protection and appropriate backup power can help reduce the impact of electrical interruptions on your home office.
Phoenix residents should also keep important data backed up. The City of Phoenix recommends backing up data as part of monsoon preparedness.

- Replacing major appliances
- Installing a home office
- Upgrading electrical service
- Adding expensive electronics
Combining electrical improvements can make it easier to create a more reliable and organized electrical system.
Why Professional Surge Protection Installation Matters
Whole-home surge protection connects directly with your home’s electrical system and should be properly selected and installed.
An electrician can evaluate:
- Your electrical panel
- Existing service
- Grounding and bonding
- Available panel space
- Electrical system condition
- Surge protection requirements
- Appropriate protective equipment
Proper installation is important because surge protection works as part of the overall electrical system.
Do Not Rely on One Surge Protector for Your Entire Home
A single plug-in surge protector cannot protect every electrical device in your home.
For example, placing a surge protector behind your television does not automatically protect your HVAC system, refrigerator, garage door opener, or other permanently connected equipment.
A combination of whole-home protection and properly selected point-of-use protection may provide a more comprehensive approach.
Preparing Your Home for Power Outages
Surge protection is only one part of electrical preparedness.
Phoenix homeowners can also prepare by:
- Keeping backup batteries charged
- Backing up important computer data
- Having flashlights available
- Using battery-powered equipment when appropriate
- Knowing how to manually open an automatic garage door
- Unplugging unnecessary electronics during outages
- Waiting before reconnecting major equipment after power is restored
APS recommends waiting several minutes after power is restored before plugging in or turning on major appliances and electrical equipment.
