TPD Success Story: from Fear to Freedom

Mainline Smart Home Electric reached out to us with an incredible success story that shows how important quality surge protection from TPD is for your home. Please read below!

A homeowner in the Greater Philadelphia area called Mainline Smart Home Electric LLC after their fridge had suddenly blown out. What seemed like a simple appliance problem quickly revealed something much bigger.

As we began testing other equipment in the home, we realized the refrigerator wasn’t the only casualty. The entire house had taken a massive electrical surge: dimmers, GFCI outlets, washer, dryer, kitchen appliances, the hot tub and HVAC system were all fried. Even smoke detectors were dead on arrival. The damage was staggering. The insurance company estimated over $70,000 in losses and recommended sending an engineer to document just how widespread the destruction was.

The family thought they were protected. They had purchased surge protectors from a big-box store and installed them on their two main panels. But when the surge hit, both units were destroyed, offering no real defense. That’s where Mainline Smart Home Electric stepped in.

We replaced the failed devices with two industrial-grade surge protectors from TPD, one on each main panel. These weren’t store-bought gadgets—they were professional-grade, engineered to handle the kinds of surges that can wipe out a home in seconds. Six months later, the family’s worst fear came true: another surge slammed into their home. But this time, the ending was different. Both surge protectors did exactly what they were designed to do. They absorbed the hit and saved every appliance and system in the house.

Relieved, but still cautious, the homeowner asked us to go further. So, we added a TPX compact surge protector on every HVAC disconnect and a TPX-150 directly at the meter, to create a stronghold at the home’s entry point. Now, instead of living in fear, this family lives with confidence. They’ve endured power outages and utility surges since, and every time, their systems have remained safe and sound.

Before having TPD surge protection, this family unplugged appliances every time a storm rolled in. They even shut down HVAC equipment at the disconnects, terrified of losing more. Now, they leave for vacation without worry. Their home is protected, their investments secure, and their peace of mind restored.

For them, surge protection became the difference between living in fear and living free. We believe no family should lose $70,000 worth of equipment or their sense of security because of something preventable. That’s why we use Transient Protection Design power quality solutions, modern-day heroes against electrical surges.
