My AC hadn’t been working for the past few days. We quoted 2 different companies and they were unreasonably priced. Finally when I contacted Affordable they were able to come out that same day. They were so nice and understanding of mine and my husband’s financial situation and were able to replace our unit the following day for a reasonable price. 10/10 would recommend!

This company is truly affordable and awesome! When we are ready for a new unit we will be using them. Our a/c went out right before the extreme heat wave. We are new to the area, saw this company online, called and Bobby came out the next morning. He found the issues, fixed them, set us up for service schedule, but most importantly-did not price gouge us nor try the whole "You need a new unit now" salesman stuff as it was not needed at this time. He was extremely informative-told us what to do going forward. Bobby-you saved us big time! THANKS!!!

Mini Split Repair Service in Ten Mile, TN

A malfunctioning ductless mini split can be frustrating, especially since you rely on it for both heating and cooling. At Affordable AC & Service, we specialize in the repair of these advanced systems. Our certified technicians have the specific training and tools required to work on ductless technology. Whether your indoor unit is leaking water, the system is not cooling or heating effectively, or it is displaying an error code, we have the expertise to diagnose the problem accurately and provide a reliable solution. We are dedicated to restoring your zoned comfort as quickly as possible.

Our team is equipped to handle the full range of mini split issues. Common problems we resolve include refrigerant leaks, communication errors between the indoor and outdoor units, and failures of the electronic control boards. We can also address issues like a fan motor that has stopped working, a system that is making unusual noises, or a unit that has frozen over. Mini splits are complex electronic systems, and our technicians have the in-depth knowledge to trace the problem to its source, whether it is a faulty sensor, a bad capacitor, or a more complex internal issue.

Our repair process begins with a thorough and precise diagnostic inspection. A technician will evaluate both the indoor head and the outdoor condenser. They will check refrigerant pressures, test electrical components, and check the system’s diagnostic error codes. Ductless systems often provide error codes that can point a trained technician in the right direction, saving valuable diagnostic time. Once we have identified the exact cause of the failure, we will explain the issue to you clearly and provide a firm, upfront price for the repair.

With your approval, our technician will proceed with the repair. We use high-quality, manufacturer-recommended parts to ensure your system is restored to its proper function. Our technicians work with the precision and care that these sophisticated systems demand. From repairing a sensitive electronic board to properly flaring a refrigerant line connection, every step is performed to the highest standard. We respect your home, keeping the work area clean and ensuring we leave no trace behind other than a perfectly working mini split.

One of the most common repairs we perform is addressing a water leak from the indoor unit. This is almost always caused by a clog in the condensate drain line. Our technicians can quickly and effectively clear this line, resolving the leak and preventing potential water damage to your walls and floors. We will also thoroughly inspect the drain pan and connections to ensure there are no other contributing issues. This simple but critical repair can save you from a major headache.

Electrical and control board failures are also frequent in these technologically advanced systems. A power surge or simple age can cause a control board to fail, leading to a completely dead unit or erratic behavior. Our technicians are skilled in troubleshooting these complex electronics. We can test the boards and other components to isolate the failure and replace the faulty part, which is a far more cost-effective solution than replacing the entire unit. This level of technical expertise is essential for working on modern mini splits.

We are so confident in the quality of our specialized repair work that we back it with our 5-year labor warranty. This commitment to quality is a core part of our mission as a veteran-owned business. We have been building trust in the Ten Mile community for over three decades by providing reliable service and standing behind our work. When your ductless mini split needs repair, do not call a generalist; call the specialists at Affordable AC & Service.

Common Mini Split Repair Questions

Ductless mini splits are reliable, but like any mechanical system, they can experience problems. To help our Ten Mile customers, we have answered some common questions about mini split repair to help you understand potential issues and know when to call a professional.

If your mini split system is running but not cooling or heating effectively, there are several potential causes. One of the most common issues is simply a very dirty indoor unit. If the filter, indoor coil, and blower wheel are severely clogged with dust, airflow will be choked off. Without proper airflow across the coil, the system cannot transfer heat effectively, leading to a total loss of cooling or heating capacity. This is why regular maintenance and cleaning are so critical.

Another frequent cause is a problem with the refrigerant level. Mini splits rely on a precise charge of refrigerant to operate. If there is a leak in the system, the refrigerant level will drop, and the unit will lose its ability to heat and cool. A technician will need to find and repair the leak before recharging the system. An issue with the outdoor unit’s compressor or fan motor can also be the culprit. If the compressor is not running, the refrigerant cycle cannot happen, and no cooling or heating will occur.

The problem could also be electrical or electronic. A failed control board or a faulty sensor could be preventing the system from operating correctly. The reversing valve, which switches the system between heating and cooling modes, could be stuck. Given the complexity of these systems, if your unit is not conditioning the air, it is essential to have a qualified technician diagnose the problem. They can systematically check each component to find the exact source of the failure.

A water leak from your indoor mini split unit is a common problem that requires prompt attention to prevent water damage to your home. The first thing you should do is turn the unit off using your remote control. This will stop the cooling process, which is what generates the condensation, and should stop the leak. You can place a towel or a small bucket under the leak to catch any remaining drips. This problem is almost always caused by a clog in the system’s condensate drain line.

As the mini split cools and dehumidifies your room, water collects on the indoor coil and drains into a pan. A small drain line is supposed to carry this water from the pan to the outside of your home. Over time, this dark, damp drain line can become clogged with a buildup of algae, mold, and slime. When the line is blocked, the water has nowhere to go, so it backs up and overflows the drain pan, causing water to drip out of the unit and down your wall.

While you should turn the unit off, you should not attempt to fix the clog yourself. Poking objects into the drain line can damage it, and using harsh chemicals can corrode the system’s components. The best course of action is to call a professional technician from Affordable AC & Service. We have the proper tools, such as specialized vacuums and pressurized nitrogen, to safely and effectively clear the clog from the line. We can have the problem fixed quickly and prevent it from happening again.

Blinking lights or alphanumeric error codes displayed on your indoor mini split unit are the system’s way of telling you that it has detected a problem. These systems have sophisticated self-diagnostic capabilities. When a sensor detects an abnormal reading or a component fails to respond as expected, the main control board will generate a specific error code. This code provides a valuable clue for a trained technician to help them quickly identify the source of the malfunction. Each manufacturer has its own unique set of error codes.

The meaning of the codes can range from simple issues to serious failures. For example, an error code could indicate a problem as minor as a dirty filter causing an airflow issue. It could also point to more significant problems like a communication error between the indoor and outdoor units, a faulty thermistor (temperature sensor), a problem with the fan motor, or a major issue with the compressor or the inverter board in the outdoor unit. It is the system’s cry for help.

As a homeowner, you can consult your owner’s manual, which may list some of the basic error codes and suggest simple troubleshooting steps, like cleaning the filter or resetting the power to the unit. However, most error codes point to internal problems that require professional diagnosis and repair. The best thing to do is to write down the specific code or the pattern of the blinking lights and provide this information to our technician when you call. This can help us diagnose and resolve the issue even more efficiently.

The cost of repairing a ductless mini split can vary widely, just like with any HVAC system. The final price depends entirely on the nature of the problem, the cost of the required replacement parts, and the amount of labor needed to complete the repair. Minor and common repairs are generally on the more affordable end. This can include things like clearing a clogged condensate drain line to stop a water leak, replacing a faulty capacitor in the outdoor unit, or replacing a remote control. These issues can often be resolved quickly with inexpensive parts.

Repairs that involve more complex components or more labor will fall into a mid-range cost category. For example, replacing a fan motor in either the indoor or outdoor unit is a more involved job. Replacing a faulty thermistor or sensor within the indoor unit requires careful disassembly and reassembly. Repairing a refrigerant leak also fits here, as it requires time to locate the leak, make the repair, and then properly recharge the system. We always provide a firm, upfront price before any of these repairs are started.

The most expensive repairs for a mini split involve the core electronic and mechanical components. Replacing the main electronic control board in either the indoor or outdoor unit can be costly, as these parts are complex. The most expensive repair is typically replacing the compressor in the outdoor unit. If a major component like a control board or compressor fails, especially on an older system, we will provide you with a detailed comparison of the repair cost versus the cost of replacing the unit or system, allowing you to make a smart financial decision.

Ductless mini splits are known for their incredibly quiet operation. If you start to hear strange noises like rattling, buzzing, gurgling, or grinding, it is a clear indication that something is wrong. A rattling noise coming from the indoor unit could be as simple as a loose filter or front panel, but it could also indicate a problem with the blower wheel being off-balance or having debris caught in it. A rattling from the outdoor unit could mean loose housing panels or debris inside the unit.

A buzzing or humming noise is often an electrical issue. It could be coming from a failing capacitor, a faulty contactor, or the transformer. These are all signs that an electrical component is struggling and may be about to fail completely. It is important to have these electrical noises checked out immediately by a professional to prevent further damage. A gurgling or bubbling noise might be heard if there is a refrigerant leak or an issue with the condensate drain, indicating improper fluid movement.

A grinding noise is one of the most serious sounds your system can make. This almost always indicates a problem with a motor’s bearings. A grinding noise from the indoor or outdoor fan motor means the motor is failing and needs to be replaced before it seizes up entirely. If the grinding noise is coming from the compressor in the outdoor unit, it is a sign of a severe internal failure, which is a major and expensive repair. If you hear any of these unusual sounds, turn the system off and call for a professional inspection.

Yes, a refrigerant leak in a ductless mini split system can and should be repaired. Refrigerant is not a fuel; it does not get “used up” over time. Your mini split has a sealed, closed-loop system, and if the refrigerant level is low, it is always because there is a leak somewhere. Simply “topping off” the system with more refrigerant without finding and fixing the leak is not a real solution. It is environmentally irresponsible and the problem will just happen again as the new refrigerant leaks out, wasting your money.

Finding a leak in a mini split system requires skill and the right tools. The most common location for a leak is at the flare connections where the refrigerant lines connect to the indoor and outdoor units. If these were not flared or tightened correctly during installation, they can leak over time. Leaks can also develop in the evaporator or condenser coils due to vibration or corrosion. Our technicians use tools like electronic leak detectors and UV dye to pinpoint the exact location of the leak.

Once the leak is found, the repair method depends on the location. A leaky flare connection can often be fixed by re-flaring the copper tubing and tightening the connection properly. A leak in a coil is more complex and may require brazing to patch the hole. After the leak has been repaired, the technician will perform a pressure test to ensure the repair is solid. Then, they will pull a vacuum on the system and recharge it with the precise amount of refrigerant specified by the manufacturer.

If your mini split’s remote control suddenly stops working, there are a few simple troubleshooting steps you can take before calling for a repair. The first and most obvious step is to replace the batteries. Dead or weak batteries are the number one reason for a remote to fail. Make sure you insert the new batteries correctly, paying attention to the polarity (+ and -). This simple fix solves the problem the vast majority of the time.

If new batteries do not work, check to see if there is a clear line of sight between the remote and the indoor unit. Obstructions can sometimes block the infrared (IR) signal. Also, make sure you are within the remote’s effective range, which is typically around 20-25 feet. You can test if the remote is emitting an IR signal by pointing it at the camera of your smartphone. When you press a button on the remote, you should see a small light flash on your phone’s screen, which is the IR signal that is invisible to the naked eye.

If you have tried these steps and the remote still does not work, the issue could be with the remote itself or with the IR receiver on the indoor unit. If you have a multi-zone system with other remotes, try using a different remote to control the problematic unit. If another remote works, then you know your original remote has failed and needs to be replaced. If no remotes work on that specific unit, then the problem is likely with the unit’s IR receiver or its control board, which will require professional repair.
