If your home still runs on a 100-amp panel, a fuse box, or an old Federal Pacific or Zinsco panel, an upgrade isn't just a convenience — it's a safety upgrade. We replace tired service equipment with modern 200-amp panels that handle today's loads: heat pumps, EV chargers, hot tubs, induction ranges, and shop equipment.
We've been doing electrical panel upgrade work across Greeneville and Greene County for years. From Downtown Greeneville, Tusculum, Mosheim to the surrounding communities, we know the local housing stock, the local code officials, and the utility companies that serve Greeneville, TN. That means faster permits, cleaner installs, and zero surprises.
