What Our Customers Say

Rated 4.9/5 by Connecticut homeowners. Real reviews from real customers.

Ergon Electric upgraded our panel from 100A to 200A and installed an EV charger for our Tesla. Professional, on-time, and the price was exactly what they quoted. Highly recommend.

Panel Upgrade + EV Charger

After getting three quotes for recessed lighting in our kitchen remodel, Ergon was the most thorough and transparent. The work was flawless — 12 recessed lights with dimmers. Kitchen looks amazing.

Lighting Installation

Had a Generac 22kW generator installed before winter. From the first assessment to final inspection, Ergon handled everything — permits, gas line, electrical. Generator runs perfectly. Peace of mind.

Generator Installation

Emergency call at 10pm for a sparking outlet. Their electrician was at our door in 35 minutes. Found a loose connection in the junction box, fixed it safely. Can't put a price on that kind of response.

Emergency Service

Complete rewiring of our 1920s colonial. Ergon's team was incredibly careful with our plaster walls and historic trim. New panel, new wiring, new outlets everywhere. Home insurance dropped our rate by 15%.

Robert M.

Fairfield, CT

Whole-Home Rewiring

Installed Lutron Caseta throughout the house — 24 switches and dimmers. Everything works perfectly with our Apple HomeKit setup. The electrician even programmed our favorite lighting scenes. Amazing attention to detail.
