Serving Corinth and Alcorn County

Corinth sits at the top of Mississippi, just a few miles south of the Tennessee line. Summers here are no different than anywhere else in the Deep South — heat index values push past 100°F from June through August, and the humidity doesn't let up after dark. That's the kind of heat that shortens the life of an AC unit that hasn't been serviced in a few years.

We've worked on systems in residential neighborhoods, along the US-72 commercial corridor, out near Shiloh, and everywhere in between. If you're in Corinth or anywhere in Alcorn County, we can get to you.

Winter is a different story. Corinth sits close enough to the Tennessee border that ice storms roll through every few years without much warning.

When they do, heating systems that have been ignored since the last cold snap start breaking down fast. We offer maintenance plans that catch those problems before the temperature drops.

Why Corinth Businesses Call S.I. Service Group

Most HVAC contractors focus on residential work. We handle commercial systems too — rooftop units, split systems, package units, and building-level climate control. If your business depends on a working HVAC system to operate, downtime costs you money, and we take that seriously.

Our lead technician, Dan Southwick, holds dual A.A.S. degrees in both HVAC and Electrical — a combination that's genuinely rare in this trade. When an HVAC problem turns out to have an electrical root cause, we don't have to call someone else in. We diagnose and fix it in one visit.
