Whole House Surge Protection
Whole House Surge Protection in Philadelphia & the Main Line
A surge protector at your panel cuts voltage spikes down before they reach your furnace, fridge, washer and TV. A plug-in strip guards one outlet. This guards the whole house.

Where Power Surges Come From
Most surges start inside your home. Each time a motor in an AC unit, fridge or washer turns on or off, it sends a small spike down the wiring. One spike rarely does harm, but thousands of them wear down the circuit boards in modern appliances over time. Bigger surges come from outside: utility switching, downed lines and lightning strikes nearby. Today's homes are full of electronics that react badly to these spikes, from furnace control boards to smart TVs, LED drivers and EV chargers. A plug-in strip only protects what is plugged into it. Hardwired equipment like your HVAC system, range and garage door opener gets no protection from a strip at all.
What Surges Damage
- Furnace and AC control boards
- Fridges, washers and ranges
- TVs, computers and routers
- LED lights and smart devices
- EV chargers and garage door openers
How We Do It
How Whole House Surge Protection Works
A whole house surge protective device, or SPD, mounts at your main panel or right beside it. When voltage jumps, it sends the extra energy to ground before it spreads through your circuits. That is why good grounding matters as much as the device, and we check your grounding electrode system on every install. We pick a device rated for your service, connect it with short, direct leads for the best performance, and confirm its status light shows it is working. The 2020 National Electrical Code added a surge protection rule for new and replaced home services in section 230.67. Which code edition applies depends on your city or township, and Electrical Hazards, Inc. checks that when we plan the job.
What We Check and Install
- Grounding and bonding checked first
- An SPD rated for your service
- Short, direct connection leads
- Status light confirmed working
- Permit where the job needs one
Why It Pays Off
Layered Protection Works Best
No surge device can stop a direct lightning strike to your house, and an honest electrician will tell you so. What a whole house device does is take the edge off the surges that happen far more often. For the best protection, pair it with plug-in surge strips at your TV, computer and home office. The panel device handles the big hits, and the strips catch what is left at the outlet. If we are already replacing your panel or upgrading your service, adding surge protection during the same visit saves you a separate trip later.
Good Times to Add Surge Protection
- During a panel upgrade
- After a storm damaged electronics
- When adding an EV charger
- With a new smart panel
- When you buy new HVAC equipment

FAQ
Frequently Asked Questions
Is whole house surge protection worth it?
For most homes, yes. Modern HVAC systems, appliances and electronics all use circuit boards that surges can damage, and one panel device protects all of them at once.
Does it protect against lightning?
It reduces damage from nearby strikes and utility surges. Nothing fully protects against a direct strike to the house.
What is the difference between a Type 1 and Type 2 surge protector?
A Type 1 device can go on the line side of the main disconnect. A Type 2 device goes on the load side, usually in or next to the panel. We choose based on your setup.
Do I still need surge strips?
Yes, for sensitive electronics. The panel device handles large surges, and strips at the outlet add a second layer.
How long does a surge protector last?
It depends on how many surges it absorbs. Most have a status light, and when it shows a fault, the device needs replacing.
