Protecting Your Knoxville Home with Whole-Home Surge Protection

Case Overview

A homeowner in Knoxville hadn’t had their HVAC or electrical systems inspected in over three years. Although everything seemed to run fine, they wanted peace of mind and an expert eye on their brand-new heating and cooling equipment. They called HEP for a routine check—no urgent problem, just a desire to prevent surprises.

How the Issue Was Solved

A HEP technician performed a full HVAC preventive maintenance inspection (PMI) and found the system operating perfectly.
The same visit included an electrical PMI to make sure cores, breakers, and wiring were in safe condition.
To guard against power spikes, the homeowner chose to add two surge protection devices:
- A whole-home unit installed inside the main electrical panel
- A dedicated protector for the outdoor condensing unit
The homeowner also signed up for a loyalty plan for ongoing coverage and left a five-star review.

Why Regular Maintenance Matters

Efficiency & Comfort: Dust, loose wires, or minor wear can quietly reduce efficiency and indoor comfort.
Early Detection: Routine checks let technicians spot small issues—like a worn capacitor or a dusty coil—before they become major repairs.
Warranty & Longevity: Many manufacturers require annual inspections to keep warranties valid.

Surge Protection in Your Panel

A surge protector inside your breaker panel helps block voltage spikes from lightning strikes, utility switching, or heavy appliances starting up.
Below is an example of a well-organized breaker panel where a surge protection device can be safely installed:

Tip: Look for a protector rated for your panel’s voltage and amperage. Only a licensed technician should install or replace these devices.

Protecting the Outdoor Unit

The outdoor disconnect switch is an ideal location for a second surge device. It guards the condenser motor and controls against transient voltage:

Tip: Make sure the disconnect remains weather-tight. A proper cover and secure conduit keep moisture and debris out of electrical connections.

Verifying System Performance

Even if no repairs are needed, HEP technicians use diagnostic tools—like digital manifold gauges—to confirm refrigerant pressures and temperatures are spot on. Regular checks prevent inefficiency and help your system run quietly and smoothly:

Homeowner Tips for Surge Protection

Ask About Warranties: Many surge protectors include a damage warranty for your electronics.
Combine with Maintenance Plans: Bundling protection devices with a loyalty or service plan often yields better coverage and pricing.
Keep Labels Handy: Photograph or note your panel’s layout; it speeds up future work and emergency shutdowns.

By scheduling annual inspections and adding surge protection inside the panel and at the outdoor disconnect, this Knoxville homeowner now enjoys enhanced safety, system reliability, and peace of mind—all thanks to a thorough HEP technician visit.
