Is your home ready to face the next big blackout? Power outages hit when you least expect them—sometimes like a summer storm rolling in, sometimes like a fuse blowing in the night. No one likes stumbling around in the dark or worrying about spoiled food, frozen pipes, or safety risks.

At Heintz Electric, we help families keep their homes comfortable and safe, no matter what the weather or the grid throws at them. Here’s your practical guide to outsmarting the next outage with solid, actionable steps.

Pre-Outage Checklist ⚡

Preparation is your best defense. Think of it like packing a parachute before the jump. Here’s what to check before the lights flicker:

Backup Power:
Invest in a standby or portable generator. Regularly test it and keep fresh fuel handy (stored safely, away from living spaces). Want to get set up? Explore our Generators service.
Surge Protection:
Power surges after an outage can fry electronics. Install whole-home surge protection or at least use high-quality surge strips. This simple step shields your devices when the grid kicks back on. Learn more about Surge Protection.
Emergency Lighting:
Place flashlights in easy-to-reach spots. Avoid candles—battery-powered lanterns and LED lights are safer. Check batteries twice a year.
Safe Appliance Use:
Unplug sensitive electronics and appliances. When power returns, sudden surges can damage them.
Electrical System Inspection:
Have a licensed electrician inspect your system for faults, outdated panels, and loose wiring. The National Fire Protection Association (NFPA) recommends annual electrical safety checks.
Smoke & CO Detectors:
Confirm they’re working and have battery backup. These save lives—especially when power loss means furnaces or generators are running.
Essential Supplies:
Keep water, non-perishable food, a manual can opener, and a first-aid kit on hand.

The Role of Generators in Outage Readiness

A generator is your electrical “spare tire.” It keeps the essentials running: fridge, sump pump, medical equipment, maybe even heat or AC. But like any tool, it’s only as good as its maintenance.

Routine Maintenance:
Run monthly self-tests. Top off oil and fuel. Check transfer switches.
Location Matters:
Never run portable generators indoors or in garages—carbon monoxide can build up quickly.
Professional Installation:
For whole-home units, always use a certified electrician for installation. DIY jobs risk backfeeding (dangerous for utility workers) and code violations.
Know Your Load:
Only connect critical circuits or appliances. Overloading the unit can cause it to fail when you need it most.

Surge Protection: The Unsung Hero

Surges are like electrical tsunamis—silent, sudden, and destructive. When power returns, voltage spikes can travel through your wiring, frying sensitive gear.

Install Whole-Home Surge Protection:
These devices intercept surges before they reach outlets. According to the Electrical Safety Foundation International (ESFI), whole-house surge protectors are the gold standard.
Protect Data, Too:
Don’t forget phone, internet, and data cabling. Surges can travel through these lines, too.
Test Regularly:
Surge devices have a lifespan. Replace if the protection indicator shows failure.

Emergency Lighting: Safe Steps in the Dark

Tripping over a shoe in the dark is more common than you think. Avoid the chaos:

LED Lanterns:
Long-lasting and cool to the touch.
Headlamps:
Hands-free, perfect for checking breakers or walking outside.
Glow Sticks:
Safe for kids’ rooms or hallways.

Safe Appliance Use & Electrical Habits

When the power’s out, appliances can be a source of trouble:

Unplug Major Appliances:
Fridges, TVs, computers—wait until power stabilizes before plugging them back in.
Turn Off Major Breakers:
If you know how, switch off non-essential breakers. This prevents overload when power returns.
Don’t Use Gas Ovens for Heat:
It’s a carbon monoxide risk.

During the Outage: Staying Safe and Smart

Now the lights are out. What comes next? Stay calm, stay smart.

Check the Cause:
Is it just your house? Or the whole block? If it’s just you, check your breakers.
Report the Outage:
Notify your utility company so they know you’re affected.
Conserve Battery Power:
Use phones only when needed. Switch to low-power mode.
Keep Fridge & Freezer Closed:
Food stays cold longer if you keep the doors shut.
Limit Generator Use:
Run it only as needed. Store fuel outdoors, locked and away from kids.
Monitor Carbon Monoxide Detectors:
If you’re using a generator or alternate heat, keep detectors near sleeping areas.
Stay Warm (or Cool):
Dress in layers. Use blankets. In summer, relocate to cooler areas if possible.

After Power Returns: What to Check

The hum of appliances returning is a relief. But your job isn’t over:

Wait Before Plugging In:
Give the grid a few minutes to stabilize before turning on electronics.
Check for Damage:
Look for tripped breakers, flickering lights, or strange odors. These can signal wiring issues.
Reset Clocks and Devices:
Timers, alarms, and smart home systems may need attention.
Restock Supplies:
Replace used batteries and emergency food.
Schedule a System Check:
If you notice oddities—call in a pro for a safety inspection. For those in need of an electrician, Heintz Electric is here to help.

DIY vs. When to Call an Electrician

Some prep is a weekend project. Some isn’t. Here’s where to draw the line:

DIY:
Stocking supplies, testing generators, checking batteries.
Call a Pro:
Installing surge protection, backup generators, rewiring, or if you smell burning or see sparks.

Common Mistakes & How to Avoid Them

Ignoring Surge Protection:
Don’t let a $30 device save you thousands in damages.
Improper Generator Use:
Never backfeed or run generators indoors.
Waiting Too Long:
Don’t wait for the next storm warning. Prep early.
Overloading Circuits:
Running too much at once can trip breakers or damage equipment.

Timeline & Disruption: What to Expect

Some outages are over in an hour. Some last days. The better your prep, the less disruption you’ll face.

Short Outages:
Minimal, but still unplug sensitive gear.
Long Outages:
Rely on backup power, conserve fuel, check on neighbors.

Seasonal Considerations

Winter:
Frozen pipes are a risk; keep a trickle of water running.
Summer:
Heat can be a danger for young kids and seniors. Seek cool shelter if the outage lasts.
Storm Season:
Review your prep every spring and fall.

Signs of Trouble: When It’s More Than an Outage

If you notice:

Smoke or burning smells from outlets.
Repeated breaker trips.
Lights that don’t come back on after the grid is restored.

Call an electrician immediately. These can be signs of wiring or panel damage.

Prevention & Maintenance: Staying Ahead

Schedule regular electrical system inspections. The National Electrical Code (NEC) is updated every three years—make sure your home is up to date. Well-maintained systems weather outages better and bounce back faster.

Costs & Time Factors

Surge Protection:
Affordable peace of mind—installed in a few hours.
Generator Installation:
Varies by size; whole-home units take a day or two, but the investment pays off.
Routine Maintenance:
Small costs now prevent major repairs later.

Frequently Asked Questions

How often should I test my generator?
Monthly, with a full load test every 6-12 months.

Can I install surge protection myself?
Outlet strips, yes. Whole-home units require a licensed electrician.

Is my electrical panel up to code?
If your home is over 20 years old, have it checked.

What should I do if the outage damages my appliances?
