Atlanta’s oppressive humidity and heavy pollen counts put a massive strain on commercial HVAC units. When your rooftop unit struggles against a 95-degree July afternoon, your business risks downtime and unhappy tenants. R.S. Andrews has kept Metro Atlanta businesses cool since 1968 with fast, local response times.

If your facility is struggling to maintain consistent temperatures, you can schedule service online to have a certified technician evaluate your system.

Signs Your Business Needs Commercial Air Conditioning Service

If you operate a large commercial facility, the signs that you may need air conditioning services are not always immediately noticeable. With time, though, these costs can increase and place a greater strain on your cash flow. As you’re inspecting your building, keep an eye out for: 

  • Rising Energy Costs. Monthly utility bills that increase without a change in usage often indicate a drop in system efficiency.

  • Inconsistent Temperatures. Cold and hot spots throughout a building suggest issues with ductwork or internal components.

  • Unusual Noises. Grinding, squealing, or banging sounds coming from the unit typically signal mechanical failure.

  • Poor Air Quality. Excessive dust or high humidity levels inside the building point to a failing filtration or dehumidification system.

  • Short Cycling. Systems that turn on and off rapidly are likely experiencing thermostat errors or compressor strain.

These can all signal issues with your AC system. Our technicians are trained to identify the causes of air conditioning issues in commercial spaces, no matter the size, and to repair them effectively. 

Commercial Air Conditioning Services

As a primary service line for Metro Atlanta businesses, R.S. Andrews provides support for every stage of a commercial cooling system’s lifecycle.

Commercial AC Repair

Mechanical failures in a commercial setting require immediate attention to prevent operational downtime. Our technicians diagnose issues ranging from refrigerant leaks and frozen evaporator coils to electrical malfunctions and sensor failures. We perform thorough inspections of central plants or rooftop units to restore cooling capacity quickly.

Commercial AC Maintenance

Routine preventative service is necessary to extend the lifespan of industrial-grade equipment. Maintenance visits include cleaning condenser coils, checking refrigerant levels, and lubricating moving parts. These sessions help identify minor wear before it leads to a total system shutdown during peak summer months.

Commercial AC Installation and Replacement

When a system reaches the end of its functional life, a full replacement is required. Our team sizes high-efficiency units specifically for your building’s heat load and square footage. We integrate new systems into your existing ductwork and building management controls for a seamless transition.

System Upgrades & Retrofits

Outdated systems lead to high utility bills and maintenance headaches. We’ll help you upgrade your AC setup with more efficient technology without having to overhaul your entire infrastructure.

Schedule today! We’re ready to deliver expert service and a smile to your door.

April 21, 2026: Well, R.S. Andrews came to my rescue again. This time I needed the water supply lines to 2 of my toilets replaced as per my homeowners insurance company. Loren, the RS Andrews plumber, was able to replace both lines with only a slight hiccup in one of the lines. He did an excellent job and detailed everything in my receipt so that I could forward my receipt to the insurance company. Loren was awesome. Thank you RS Andrews for saving the day….again. February 2026: Will Macon was totally awesome! I’m a caregiver for my 89 year old mother who just came out of the hospital on Sunday. Our furnace went out on Tuesday. I called R. S. Andrews on Tuesday. Will was at our home on Wednesday morning. He examined our system and got us a GREAT DEAL on a new furnace and AC. It was awesome. The new system was installed on Thursday. By Thursday afternoon we had heat from a NEW FURNACE. Thank you Will and thank you R. S. Andrews for all that you do. You may have saved a life. Thank you!!!! Alane L. Sullivan

After having a couple other companies look at our plumbing and tell us they "couldn't" fix our problem (we have a mixture of stainless steel & cooper pipes; virtually unheard of for residential!), we tried R.S. Andrews. Their attitude from the start was "How can we help" and they found a solution! Not only did they solve that problem, but we've used them for all plumbing and HVAC needs since because the folks provide great service at a fair price!

All the Techs that R S Andrews has sent were very courteous and professional. All details for the repairs were explained along with any follow up visits. Any costs were explained before the Techs came out. I would recommend R S Andrews to anyone who needs home repair.

Brian Turner, technician, and his assistant did an excellent job of diagnosing a gas leak at my water heater and redesigning a more efficient setup and replacing the water heater. It was a huge all day job and they worked tirelessly to make sure things were improved and safe. He was excellent at explaining every step and the reason for the changes. He also repaired other small issues in tub and outdoor faucets.
