Whole Home Surge Protection: Protect Everything Before It's Too Late.
Power surges can happen at any time, and most homeowners don't realize one occurred until something suddenly stops working.
A refrigerator that won't turn on. A furnace control board that's fried. A TV that goes black. An AC unit that won't start during a Colorado heat wave.
The damage is often instant, and it's often permanent.
Power Electrical, Heating & Cooling Services installs whole home surge protection systems for homeowners across the Denver metro area, helping protect appliances, electronics, HVAC systems, and sensitive electrical equipment from the surges that happen every single day.
Don't wait until something gets damaged.
What Is Whole Home Surge Protection? in Arvada
Most homeowners have at least one power strip with built-in surge protection somewhere in the house.
That only protects the devices plugged directly into it, and nothing else.
Whole home surge protection is completely different.
A surge protection device installed at your electrical panel acts like a shield for your entire home's electrical system, intercepting excess voltage before it reaches your wiring, outlets, appliances, or HVAC equipment.
Think of it as a security system for your electrical system.
Instead of protecting one television or one computer, it protects your entire home automatically every time a surge occurs.

What Causes Power Surges?
Most people think of lightning when they hear the term power surge, but lightning actually causes only a small percentage of the surges your home experiences.
The more common causes are things most homeowners never think about.
• Lightning strikes: Direct or nearby strikes can send massive voltage spikes through your electrical system instantly
• Utility grid switching: Power companies regularly switch between grid segments, creating surges that travel into homes
• Power restoration after outages: When electricity is restored after an outage, the returning surge can be significant
• Large appliances cycling on and off: AC systems, refrigerators, and other large appliances create small internal surges every time they start up
• Downed power lines: Storm damage and utility issues can create unpredictable voltage spikes
• Shared utility transformers: Surges from nearby homes connected to the same transformer can affect your home as well
In Colorado specifically, the risk is even higher.
Colorado ranks among the top states in the country for lightning strikes per square mile, and severe summer thunderstorms happen during the exact months your AC system is working hardest.
That combination makes surge protection more than just a smart investment here. It makes it genuinely important.

Three Levels of Surge Protection We Offer
Not all surge protection is equal, and one device doesn't protect everything.
The most effective protection uses a layered approach that protects your home at the panel level while adding dedicated protection to your most expensive and vulnerable systems.
Your first and most important line of defense.
A whole home surge protector installs directly at your electrical panel and intercepts large voltage spikes before they reach your home's wiring.
• Protects your entire home's electrical system at once
• Helps defend against lightning, utility switching, and power restoration surges
• Operates automatically with no switches or maintenance required
• Recommended for every home regardless of age or location
• Fast installation, usually completed in under two hours
Your AC system is one of the most expensive and surge-sensitive appliances in your home.
Air conditioners draw large amounts of power and create internal voltage fluctuations every time they cycle on and off. Combine that with Colorado's intense summer storm season, and the risk becomes significant.
A dedicated surge protector installed directly at the outdoor condenser adds another layer of protection specifically for your cooling system.
• Protects your AC compressor and control board from surge damage
• Especially important during Colorado's summer lightning season
• Helps extend the lifespan of your AC system
• Costs far less than a compressor or control board replacement
• Installs directly at the outdoor condenser unit
Your furnace control board is the brain of your heating system, and it's surprisingly vulnerable to power surges.
A single surge can destroy the control board instantly, leaving you without heat during a Colorado winter and facing an expensive repair.
A dedicated furnace surge protector helps protect the control board, ignitor, blower motor, and other sensitive HVAC components.
• Protects one of the most common and costly surge-related failure points
• Helps protect blower motors, ignitors, and HVAC electronics
• Especially important during Colorado's harsh winter conditions
• Works alongside your panel surge protector for layered protection
• Installs directly at the furnace or air handler

Joey came out and did a fantastic job looking over and cleaning my system for the winter. I had someone come out earlier in the year, but it felt more like he was trying to get me to buy a new system than help with my existing. Joey looked over the system, gave a few small but very helpful suggestions, and cleaned it. Could not recommend these folks enough.

I had purchased an oven and needed an outlet swap as soon as possible. Lance came out right at the beginning of the service window, was very thorough during the estimate procedure and was extremely knowledgeable and answered a lot of questions I had about my circumstance. Couldn't be happier with the communication and service performed. I will definitely utilize this company again in the future.

Just moved into our new (2000 build) house and Joey came out to do winter maintenance on our furnace. This company was recommended from the former owner. Joey was professional, polite and very helpful - showing me how to change the furnace filter and the humidifier pad. He cleaned out the furnace, inspected the system, (which is newer) and told me everything was in good shape – didn’t try to sell me anything extra. I like them and will use them again.

The Whole Home Surge Protection Installation Professionals
Short Answer: Absolutely, Especially in Colorado.
Here's the honest math.
A layered surge protection system protects thousands of dollars worth of appliances, HVAC equipment, electronics, and smart home devices.
Now compare that to common surge-related replacement costs:
• Furnace control board replacement: $500 to $2,000+
• AC compressor replacement: $1,500 to $3,000+
• Refrigerator replacement: $800 to $2,500+
• Smart home equipment damage: Often thousands more
• Multiple damaged appliances after one surge event: Potentially $5,000 to $10,000+
And that's before considering the inconvenience of losing heat during winter or AC during a Colorado summer while waiting on repairs and replacement parts.

1. What is whole home surge protection and how does it work?
A whole home surge protector is a device installed directly at your electrical panel that monitors incoming voltage and diverts excess voltage away from your home's electrical system when surges occur.
Unlike a power strip that protects only a few plugged-in devices, whole home surge protection helps protect your entire home's wiring, outlets, appliances, and HVAC equipment simultaneously.
The system operates automatically every time a surge occurs.
2. What's the difference between a whole home surge protector and a power strip?
A power strip surge protector only protects devices plugged directly into it, and many consumer-grade power strips offer very limited protection.
A whole home surge protector intercepts surges at the electrical panel before they travel through your home's wiring.
It protects hardwired appliances such as furnaces, AC systems, refrigerators, and other equipment that can never be connected to a standard power strip.
The best setup is both: whole home protection as the primary defense and quality surge strips as secondary protection for sensitive electronics.
3. What causes power surges in Colorado homes?
Colorado homes experience surges from lightning, utility switching, power restoration after outages, voltage fluctuations, and large appliances cycling on and off.
Colorado also ranks among the top states for lightning activity per square mile, making surge protection especially important here.
Most homeowners experience small surges regularly without realizing it.
Over time, those repeated surges slowly damage electronics and appliances even when there is no immediate visible failure.
4. What appliances and electronics are most vulnerable to surge damage?
The most vulnerable systems are those with sensitive electronic control boards.
Furnace control boards are one of the most common surge-related failures we see. AC compressors and control boards are also highly vulnerable.
Refrigerators, washers, dryers, dishwashers, smart TVs, gaming systems, computers, smart thermostats, and home automation equipment are all sensitive to surge damage.
In today's homes, almost everything contains electronic circuitry.
5. How long does whole home surge protection installation take?
A standard panel surge protector installation is usually completed in under an hour.
If we are also installing dedicated protection at the AC system and furnace, most projects are still completed within two hours.
There is a brief power shutdown during installation, and we coordinate that with you beforehand.
6. Does surge protection replace homeowner's insurance?
No.
Surge protection and homeowner's insurance serve different purposes.
Surge protection helps prevent damage before it happens. Insurance helps cover losses after damage occurs, often with deductibles, coverage limits, and exclusions.
Many policies also limit coverage for electronics or certain types of electrical damage.
Prevention is always better than replacement.
Some insurance providers even offer discounts for homes with professionally installed surge protection.
7. How do I know if my home has already experienced a power surge?
Common signs include appliances that suddenly stopped working, electronics behaving erratically, smart devices resetting unexpectedly, furnace or AC systems failing after storms or outages, or equipment that no longer operates correctly for no obvious reason.
Small repeated surges can also shorten appliance lifespan gradually without causing an immediate failure.
If problems appeared after a lightning storm, outage, or power restoration event, surge damage is very possible.
