Our Commercial Division
Commercial HVAC Is What We’re Built For
Commercial HVAC has been a core part of State Mechanical since Jerry Still built the commercial division in the 1970s. For over 50 years, we’ve been the contractor that property managers, general contractors, and business owners in Northeast Georgia call when the work needs to be done right.
Our commercial work is heavily focused on remodels and retrofits — taking existing buildings and upgrading or replacing their HVAC systems while minimizing disruption to your operations. We work in retail spaces, office buildings, restaurants, warehouses, and everything in between.
As an authorized American Standard dealer, we source and install commercial-grade equipment built for the demands of Georgia’s climate and your facility’s specific requirements.

Installation, replacement, and service of packaged rooftop units for commercial buildings of all sizes. We have the equipment and experience to work safely at height on flat and low-slope roofs.
Commercial Mini-Splits
Ductless mini-split systems for server rooms, additions, restaurants, retail spaces, and any commercial application where extending ductwork isn’t practical or cost-effective.
Remodels & Retrofits
Our primary commercial specialty. We work with contractors and property owners to upgrade or replace HVAC systems in existing commercial spaces — minimizing downtime and working around your schedule.

Full commercial system replacements handled from start to finish. We remove old equipment, install properly sized new systems, and test everything before we leave — with minimal disruption to your business.
