Air Conditioner Repair | Fast, Local Service

If your air conditioner isn’t cooling, is running constantly, or won’t turn on at all, it’s time to schedule air conditioner repair. Most AC problems start small, but once the system begins running heavily during the summer, those issues can quickly turn into a complete loss of cooling.

Air conditioner repair focuses on identifying the cause of the problem and restoring your system so your home stays comfortable. Whether the issue is electrical, airflow-related, tied to refrigerant levels, or caused by components like capacitors, contactors, blower motors, or condensate safety switches, getting the problem diagnosed early helps prevent further damage and longer downtime.

Common Air Conditioner Problems We Fix

Air conditioning systems can fail in a variety of ways. Some problems develop slowly, while others seem to happen overnight. In many North Atlanta homes, air conditioning problems become much more noticeable during the first major heat wave of the season, when systems suddenly shift from occasional spring usage to running most of the day.

We regularly diagnose and repair issues such as:

• Air conditioner not blowing cold air
• System running but not cooling the home
• AC turning on and off frequently (short cycling)
• Weak airflow from vents
• Thermostat not responding or inaccurate readings
• Strange noises coming from the system
• Water leaking around the indoor unit
• Outdoor unit not turning on

Will My Air Conditioner Need Repair or Replacement?

Many air conditioner problems can be repaired without replacing the entire system. Issues like weak capacitors, failing contactors, clogged drain lines, thermostat problems, frozen evaporator coils, and restricted airflow are all common air conditioner repairs we see during the summer.

In many cases, homeowners assume the system has completely failed when the actual problem is much smaller and more repairable than expected.

However, replacement can sometimes make more sense if the system is older, repairs are becoming more frequent, or major components are failing. During your repair visit, your technician will inspect the system, explain what’s happening, and help you understand whether repair or replacement is the better long-term option for your home.

What Happens During an Air Conditioner Repair Visit

Every repair starts with a thorough inspection of your system.

Your technician will check both the indoor and outdoor components, focusing on the areas most likely to affect performance. This typically includes electrical components, refrigerant levels, airflow, and system controls.

Common steps include:

• Testing capacitors, contactors, and electrical connections
• Measuring refrigerant pressures and system performance
• Inspecting the condenser coil and outdoor unit
• Checking the evaporator coil and airflow across the system
• Evaluating the thermostat and system controls
• Inspecting the condensate drain line
• Checking float switches and condensate pumps for drainage problems
• Inspecting blower motor performance and airflow restrictions
• Looking for dirty condenser coils and restricted air filters that may strain the system
• Testing low voltage controls and communication between system components

Once the issue is identified, your technician will explain what’s happening and walk you through your options before any work is done.

Before Your AC Repair Visit: What to Do If Your System Isn’t Cooling

If your air conditioner isn’t cooling properly, one of the most important steps you can take before your technician arrives is to turn the system off and allow it to thaw.

When an air conditioner has airflow issues or low refrigerant, the evaporator coil can become too cold and begin to freeze. As ice builds up on the coil, airflow becomes more restricted, which causes the system to struggle even more. Restricted filters, blower motor issues, dirty evaporator coils, and low refrigerant are some of the most common causes of this type of freezing problem. The longer the system runs in this condition, the worse the problem can become. This is especially common during Georgia summers when air conditioners may run continuously through the afternoon and evening heat.

If the system is frozen when your technician arrives, it can be difficult to diagnose the root issue. Many of the components that need to be inspected—like airflow across the coil or refrigerant performance—can’t be accurately tested while ice is present.

Turning the system off gives the ice time to melt and allows for a more accurate inspection.

If you notice:

• Little or no airflow from vents
• Ice on the outdoor line or indoor unit
• The system running but not cooling

It’s best to shut the system down and allow it to thaw before your appointment. This helps your technician diagnose the problem more quickly and get your system back to normal sooner.

Simple Checks Before Scheduling Repair

Some issues can be caused by simple problems that are easy to overlook.

Before scheduling service, you may want to check:

• Thermostat settings and batteries
• Air filter condition
• Circuit breaker for the system
• Whether the outdoor unit is running

If these don’t resolve the issue, it’s usually time for a professional inspection. Most AC problems involve internal components that require proper testing and diagnosis.

When Repair Makes Sense—and When It May Not

In many cases, air conditioner repair is the most practical solution, especially when the system is newer or the issue is isolated.

However, if the system is older, requiring frequent repairs, or struggling to cool the home efficiently, a new air conditioner installation may sometimes make more financial sense long term.

If replacement is the better path, your technician can walk you through air conditioner installation options and help you compare efficiency, sizing, and long-term operating costs.

If your system is nearing the end of its lifespan, your technician can help you compare repair and replacement options so you can make an informed decision.

How Maintenance Helps Prevent Future Repairs

Many air conditioner repairs can be avoided with regular air conditioner maintenance.

Over time, dirty condenser coils, restricted filters, worn capacitors, failing contactors, and airflow problems place additional strain on the system and increase the likelihood of breakdowns during the summer. These issues often go unnoticed until the system begins running heavily during the summer. Many homeowners don’t realize there’s a problem until the first stretch of 90-degree weather places the system under sustained demand.

According to the U.S. Department of Energy air conditioner guidance, regular maintenance and proper system operation play a major role in efficiency and lifespan. Scheduling seasonal service helps catch these problems early and reduces the likelihood of unexpected breakdowns.

Ricardo was outstanding. He came in and fixed an issue with my air conditioning prior to the installation on something else and he came out and got everything fixed. Switched out a thermostat for me that I got like three years ago and installed it and everything is great I am happier than I could ever be.

Aaron Services hit two home runs for our business yesterday when we discovered a water leak above our communications equipment. First they quickly dispatched an HVAC tech to take care of a clogged drain on the A/C unit, but then also had a plumber out in quick succession when we discovered broken pipes that needed repair. John Poole and Billy Nolan were both very professional, courteous, and conscientious about keeping the work area clean. Billy even picked up the materials we’d put down to soak up the water. 10/10 recommend them!

In the past, we've had many air conditioner repairmen, but Ricardo Arturo from Aaron Services stands out as the best. He was prompt, professional, and showed great integrity, thoroughly explaining the issue, his plan to fix it, and the price upfront. I trust him completely and plan to request only Ricardo for future repairs.

Ricardo did an awesome job!!  The air conditioner seemingly wasn’t working in our townhouse. We only have one unit, but it was working upstairs and not downstairs, which seemed very strange. Of course, when he checked the unit, everything seemed to be in working order (face palm). He then explained that it could’ve been one of two issues based on what we were experiencing. He checked the dampers and said that they looked good, which usually means that it’s the thermostat. He did confirm that since everything appeared to be working at the moment, he couldn’t be 100% sure, but said that was his best estimation. We asked him to go ahead and change it out because we did have issues with the same model thermostat upstairs previously. While he was changing it, he noticed that it seemed to be shorting out,  Indicating that it was either bad or that it may not have been installed properly. He changed the old thermostat out in less than 20 minutes. What I appreciate the most is that he didn’t try to scare me into purchasing a new thermostat or anything like that, but he gave me his honest professional opinion. I’ll definitely work with them again if we have any additional concerns.

Not only did he quickly diagnose the issue, but he also explained everything in simple terms and had my system up and running in no time. You could tell he genuinely cares about the quality of his work and the comfort of his clients. Thanks to his expertise and dedication, I was able to enjoy a cool, comfortable home again — and just in time.

We have been using Aaron for A/C and heating maintenance for several years. We usually have the same technicians for each call, so they're familiar with us and our system. On his most recent visit, John noticed a gas valve (original from 1973) was beginning to leak and replaced that before it could become a problem. I'm glad they have us covered.
