What reviewers say

Davis Services, Inc.

Davis Services earns consistent five-star feedback for fast, knowledgeable service across HVAC, plumbing, and electrical work. Technicians diagnose problems quickly, explain repairs clearly, and finish jobs within days, though some reviewers note the company charges a premium for its reliability.

Mr Electric of the Upstate

Reviewers consistently report same-day emergency response, straightforward diagnosis, and technicians who explain the problem and solution clearly. Matt, Adrian, Jason, and Dusty appear by name across multiple jobs-panel replacements, hot tub repairs, sensor lights, and major rewiring-all completed at or below quoted price with clean sites and follow-up checks.

The company builds repeat customers by not upselling and returning to answer questions after the work is done. One reviewer mentioned a sensor angle adjustment needed post-install; otherwise, reviews focus on speed, expertise, and the personal touch (technicians feeding stray animals, watering plants, or staying late without complaint when work ran longer than expected).

Verdict

The right pick depends on how much of the job is purely electrical versus multi-trade. If the generator install is a standalone electrical project, panel work, transfer switch, dedicated circuits, Mr Electric's specialist focus and its track record on similar rewiring and panel jobs make it the tighter fit, especially with pricing held to estimate and follow-up visits included. If the project also touches gas lines, HVAC, or other systems that need one company to coordinate, Davis Services' multi-trade setup and larger volume of proven jobs offer more built-in coverage, at a premium price.
