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.

Nick H did a fantastic job. He came on a Friday afternoon in August and replaced the part that was ordered, eliminating the freon leak. He spent about 5 hours completing the job. He is very knowledgeable and professional and I was very impressed.

My technician James did an incredible job. I initially had a membership with a different company. (Assured Comfort) who came out to do maintenance but would check the drain connected to my AC, it clogged and flooded and ruin my ceiling. They sent two technicians in three days that couldn’t help me, prolonging the process of repairing my ceiling because there was still water inside my AC, and Duct that they failed to fix. So what did I do? I called RS Andrews. Our technician James responded out, made sure everything was clear and operable, documented everything correctly, and referred us to the department who’ll be out to make the repairs. James was very knowledgeable and they officially have a new customer. Might I add that they DO check drains during maintenance unlike other companies but I would definitely recommend RS Andrews.

Paul and his associate were able to fix a problem that several people had turned down as being “too hard to figure out” and “would take too much time”. So I was very pleased that they were able to find the problem and fix it! I would definitely hire them again and also would not hesitate to refer to others.

Pau had to reinstall our new toilet located on our home’s second floor. He has been to our home before and always installs correctly, efficiently and is very respectful of our homes hardwood floors and interior carpeting. We are always very, very satisfied with Pau for a professional repair or a new install!

Huge thank you to Terrell Thomas! After spending the day dealing with multiple issues, losing my AC was the last thing I needed. Terrell came out after hours, quickly diagnosed the problem, explained everything in a way I could understand, and got my AC running again. He never rushed the job and made sure everything was working before he left. Professional, knowledgeable, and courteous from start to finish. I highly recommend him and really appreciate the excellent service. Thank you again, Terrell!

5/5 Stars
Our AC went out, and Nick was absolutely fantastic. Not only did he diagnose and fix our current issue, but he also discovered several installation flaws from when the system was put in a few years ago. He spent several hours meticulously bringing our unit back up to proper condition—even resolving a long-standing airflow issue in our house that we’ve had to deal with for years. Nick was super smart, super nice, and extremely helpful. I can't recommend this company and Nick highly enough!
