Claim This BusinessRS Andrews has protected indoor comfort for homeowners in Peachtree Corners and across the Greater Atlanta metro area since 1968, accumulating nearly a half-century of trust-building along the way. With a 4.9-star rating drawn from 9,197 reviews, the fully insured crew handles HVAC, plumbing, and electrical needs for both residences and light commercial properties. Their service territory extends well beyond Gwinnett County to include Savannah and the Hilton Head area of South Carolina. Crews staff emergency lines around the clock every day of the week, a detail that surfaces repeatedly in customer feedback.
What distinguishes RS Andrews goes beyond longevity. The company holds Lennox dealer status, placing factory-authorized equipment and warranty support within reach for homeowners replacing older systems. Technicians also field the REME HALO indoor air quality platform for residents wanting filtration upgrades beyond standard filters. A $99 Mega Furnace Tune Up special anchors seasonal maintenance pricing, while in-house financing removes the obstacle of lump-sum replacement costs. workmanship carries a satisfaction guarantee, meaning the job is not signed off until the homeowner confirms results. These specifics, brand partnership, air-quality specialty, financing structure, and a guarantee written in plain language, separate RS Andrews from generalist contractors who list services without backing them.
Brennan built a custom copper manifold for Angela Potts when her seven-year factory unit failed, answering questions by text and phone until the install was complete. Alane Sullivan's 89-year-old mother arrived home from the hospital on Sunday; her furnace failed by Tuesday; Will Macon diagnosed the system Wednesday morning, secured a replacement package, and had heat running by Thursday afternoon, a story customers cite as potentially life-saving. Jonte diagnosed a dirty flame sensor pin in under an hour for another reviewer, explaining the problem before leaving. These named technicians represent a pattern across 9,000-plus reviews: arrived on time, diagnosed correctly the first time, and left the customer informed.
Technicians receive specific name recognition across reviews more often than generic praise. Will Macon earned mentions for arriving the morning after a hospital discharge and fast-tracking a same-day furnace replacement, while Brennan, Jonte, Jose Sanchez, and Travon each earned individual callouts for trades ranging from copper manifold fabrication to attic fan belt replacement. Pricing concerns appeared in a small minority of reviews; the dominant sentiment praised transparent estimates that came in below initial quotes.
