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 Maintenance Service in Ten Mile, TN

Professional maintenance is crucial for the longevity and performance of your ductless mini split system. Since a mini split works year-round to both heat and cool your home, it accumulates significant run-time and requires consistent care. We strongly recommend a bi-annual maintenance schedule, with a service visit in the spring to prepare for summer cooling and another in the fall to prepare for winter heating. This proactive approach ensures your system operates at peak efficiency in every season, saving you money and providing reliable comfort. Our service is designed to address the unique needs of ductless technology.

The most critical aspect of mini split maintenance is thoroughly cleaning the indoor units. The indoor heads contain a blower wheel and an evaporator coil that can become clogged with dust, pet dander, and even mold. This buildup restricts airflow, reduces efficiency, and can negatively impact your indoor air quality. Our technicians will professionally clean the indoor unit’s filter, coil, and blower wheel, removing all contaminants. This deep cleaning is far more effective than just rinsing the filter yourself and is vital for the system’s health and performance.

During our service, we also give detailed attention to the outdoor condenser unit. We will inspect and clean the outdoor coil to ensure it can effectively transfer heat. The area around the unit will be cleared of any debris that could impede airflow. We check the refrigerant level to ensure it is correctly charged, as an incorrect charge can strain the compressor and reduce efficiency. We also inspect all electrical connections and components in the outdoor unit, tightening and testing them to ensure safe and reliable operation.

Our comprehensive tune-up includes a full system diagnostic. We test the communication between the indoor and outdoor units, which is critical for proper function. We will check the condensate drain line from the indoor unit to ensure it is clear and flowing freely, preventing water leaks and potential property damage. We test all functions of the remote control and ensure the thermostat sensors in the indoor units are reading the room temperature accurately. This ensures precise temperature control and comfort.

For multi-zone systems, we perform these checks on every single indoor unit. We will ensure each zone is operating correctly and responding to its individual controls. This ensures that the balanced comfort you invested in is maintained throughout your home. Our technicians will test the system in both heating and cooling modes to verify that all components, including the reversing valve, are functioning as they should. This complete operational check confirms your system is ready for the upcoming season.

Regular maintenance does more than just keep the system clean; it prevents costly repairs. During our inspection, our technicians can identify any parts that are showing signs of wear and tear. Addressing these small issues proactively is far less expensive than dealing with a major component failure down the road. This preventative approach greatly enhances the reliability of your mini split, giving you peace of mind that it will not fail you during a heatwave or a cold snap.

Investing in our bi-annual maintenance plan is the most effective way to protect your ductless mini split system. It keeps your energy bills low, prolongs the life of the unit, and ensures you meet the maintenance requirements of your manufacturer’s warranty. As a family-operated business, we are committed to providing the highest level of service to our neighbors in Ten Mile. Trust the experts at Affordable AC & Service to care for your advanced comfort system.

Common Mini Split Maintenance Questions

Proper maintenance is key to getting the most out of your high-efficiency ductless mini split. To help our Ten Mile customers care for their systems, we have answered some of the most common questions about mini split maintenance and its importance.

Mini split maintenance is incredibly important for several key reasons, primarily related to efficiency, air quality, and longevity. First, mini split systems achieve their high efficiency ratings partly because they are ductless. However, the indoor units themselves can become very dirty. The filters, coils, and blower wheels are prone to collecting dust, debris, and microbial growth. When these components get dirty, airflow is restricted, forcing the unit to work harder and consume more energy to heat or cool the room. Regular professional cleaning is essential to maintain the system’s peak efficiency and keep your energy bills low.

Second, maintenance is critical for your indoor air quality. Since the indoor unit is located directly in your living space, any mold, mildew, or bacteria that grows on its damp, dark internal components can be blown directly into the air you breathe. This can cause musty odors and can be a significant problem for individuals with allergies, asthma, or other respiratory conditions. A thorough professional cleaning and disinfection of the indoor unit’s coil and blower wheel removes these contaminants and ensures you are breathing clean, healthy air.

Finally, regular maintenance protects your investment and prevents costly repairs. During a tune-up, a technician can spot and address minor issues, like a loose electrical connection or a wearing part, before they can cause a major component like the compressor or a control board to fail. It also ensures the condensate drain line is clear, preventing water leaks that can damage your walls and floors. Consistent maintenance is the best way to ensure your mini split system lasts for its full expected lifespan of 15-20 years.

Cleaning the filters on your indoor mini split units is a simple and very important task that every homeowner should do regularly. Most indoor units have filters that can be easily removed, rinsed with water, allowed to dry completely, and then reinserted. You should do this every one to two months, or more often if you have pets or live in a dusty environment. This regular filter cleaning is your first line of defense in maintaining good airflow and protecting the internal components from getting dirty.

However, cleaning the filters yourself is not a substitute for professional annual or bi-annual maintenance. The mesh filters in the indoor unit can only capture the largest dust particles. Over time, smaller particles of dust, dander, and oils will pass through the filter and build up on the delicate fins of the evaporator coil and the blades of the cylindrical blower wheel. This buildup becomes a breeding ground for mold and mildew and is the primary cause of reduced efficiency and poor air quality.

A professional technician has the tools and training to safely access and deep-clean these internal components. This often involves using special cleaning solutions, low-pressure sprayers, and tools to clean the tightly packed coil fins and the hard-to-reach blower wheel without damaging them. This deep cleaning is something a homeowner cannot perform themselves and is the most critical part of a professional mini split tune-up. So, while you should clean your filters regularly, you still need professional service to clean the parts your filter protects.

Because a ductless mini split is a heat pump that provides both heating and cooling, the industry best practice is to have it professionally serviced twice a year. This bi-annual schedule ensures the system is properly prepared for the demands of each distinct season. We recommend a maintenance visit in the spring to focus on the cooling components and another visit in the fall to focus on the heating components. This is the same recommendation as for a traditional central heat pump system.

A mini split works hard all year long, so it accumulates wear and tear much faster than a furnace or air conditioner that only runs for part of the year. Servicing it only once annually would mean it would go through an entire season of heavy use without being inspected or cleaned. For example, if you only had it serviced in the spring, it would work all summer, and then you would expect it to work all winter without having the heating functions specifically checked or the grime from the summer cleaned out. This increases the risk of a breakdown and reduces efficiency.

By having a technician perform a tune-up twice a year, you ensure that the system is always clean, efficient, and reliable. The spring service gets it ready for summer, and the fall service gets it ready for winter. This proactive approach catches potential problems before they escalate, keeps your energy bills as low as possible, and is typically required by manufacturers to keep your system’s warranty valid. For a year-round comfort system, year-round care is the wisest approach.

Our professional mini split maintenance service is a comprehensive tune-up designed to address every aspect of your ductless system. The service begins with a thorough cleaning and inspection of the indoor unit or units. Our technicians will remove and clean the reusable air filters. More importantly, we will perform a deep cleaning of the indoor unit’s evaporator coil and the blower wheel to remove any accumulated dirt, dust, or microbial growth. This is critical for ensuring proper airflow, efficiency, and healthy indoor air quality.

Next, we focus on the outdoor condenser unit. We will inspect and clean the outdoor coil, removing any leaves, dirt, or debris that could restrict airflow. We check the refrigerant charge to ensure it is at the precise level required by the manufacturer for optimal performance. We inspect all electrical connections, tightening them as needed, and test the capacitors and contactors to ensure the system has reliable power. The outdoor unit is checked to ensure it is level and stable, and that the fan motor is operating correctly.

The final phase of our service involves a full system check and calibration. We will clean and inspect the condensate drain line to ensure it is clear and will not cause water leaks. We test the communication between the indoor and outdoor units and verify that the remote control is functioning properly. We then run the system in both heating and cooling modes to confirm that it is performing correctly in all functions. If you have a multi-zone system, we perform these checks on every indoor head to ensure your entire system is in top condition.

Yes, absolutely. Regular professional maintenance is one of the most effective ways to ensure your mini split continues to operate at the high-efficiency level it was designed for. The primary way maintenance improves efficiency is by ensuring the system has proper airflow. When the filters, indoor coil, and blower wheel become clogged with dirt, the fan has to work much harder to pull air through the unit. This increased effort consumes significantly more electricity. A professional deep cleaning removes these restrictions, restoring airflow and allowing the system to run with less effort.

Another key factor in efficiency is the refrigerant charge. A mini split system is designed to work with a very precise amount of refrigerant. If there is a small leak and the system becomes undercharged, or if it was improperly charged during installation, its efficiency will drop dramatically. As part of our maintenance service, our technicians check the refrigerant pressures to verify the system has the correct charge. This ensures the heat transfer process is happening as efficiently as possible, which is the core of the system’s function.

By cleaning coils, ensuring proper airflow, verifying the correct refrigerant charge, and checking all electrical components for proper function, our maintenance service restores your mini split to its factory specifications. A clean, well-tuned system can be up to 25% more efficient than a neglected one. This means that the energy savings you gain from regular maintenance can often pay for the cost of the service itself over time, making it a very wise financial investment.

Yes, preventing water leaks from the indoor unit is one of the most important benefits of regular mini split maintenance. The indoor head of a mini split system removes a significant amount of humidity from your air as it cools, just like a traditional air conditioner. This moisture condenses on the cold evaporator coil and drips into a collection pan. From the pan, the water is supposed to flow out of your home through a condensate drain line. A water leak from the indoor unit is almost always caused by a problem with this drainage system.

The most common cause of a leak is a clogged condensate drain line. The dark, damp environment of the drain line is a perfect breeding ground for algae, mold, and slime. Over time, this biological growth can build up and create a blockage in the line. When this happens, the water can no longer drain away, so it backs up and overflows the collection pan inside the unit, leading to water dripping down your wall. During our maintenance service, our technicians thoroughly flush and clean the condensate drain line to remove any blockages and prevent future clogs.

In some cases, a leak can also be caused by a cracked drain pan or a problem with the condensate pump, if your system has one. Our technicians will inspect these components as part of the service to ensure they are in good condition. By ensuring the entire condensate management system is clean and functioning correctly, our maintenance service provides excellent protection against the messy and potentially damaging problem of a water leak from your indoor unit.

The most reliable way to know your mini split needs maintenance is to follow the recommended schedule of having it professionally serviced twice a year. However, there are several signs you can look for that indicate your system is overdue for a tune-up. One of the most common signs is a reduction in cooling or heating performance. If you notice that a room is not getting as cool or as warm as it used to, or if the unit seems to be running constantly to keep up, it is often a sign of restricted airflow due to dirty components.

Another clear indicator is the presence of musty or unpleasant odors coming from the indoor unit when it is running. This smell is typically caused by the growth of mold and mildew on the damp indoor coil and blower wheel. This not only smells bad but also negatively impacts your indoor air quality. You might also notice an increase in your electricity bills, which can be a direct result of the system losing efficiency due to being dirty.

Visible signs can also alert you to the need for service. If you look inside the unit with a flashlight and can see a mat of dust on the blower wheel or grime on the coils, it is definitely time for a cleaning. Any signs of water dripping from the indoor unit or unusual noises like rattling or buzzing are also clear indicators that your system needs immediate professional attention. Sticking to a regular service schedule is the best way to avoid these problems altogether.

Neglecting to service your ductless mini split system will lead to a number of predictable and undesirable consequences. The first thing you will notice is a steady decline in performance and efficiency. As dust and grime build up on the indoor and outdoor coils, the system’s ability to transfer heat will be severely hampered. This means it will run longer and work harder to heat or cool your home, leading to a significant increase in your energy bills. The high efficiency you invested in will be completely lost.

The lack of cleaning will also lead to poor indoor air quality. The damp, dark interior of the indoor unit will become a breeding ground for mold, mildew, and bacteria. These contaminants will then be continuously circulated into the room you are living in, which can trigger allergies, and asthma, and cause other respiratory issues. You may notice a persistent musty smell whenever the unit is running. This can turn your high-tech comfort system into a source of indoor air pollution.

Over the long term, neglect will lead to premature and costly system failure. The constant strain of running with restricted airflow and dirty components will cause excessive wear and tear on critical parts like the fan motors and the compressor. The risk of a condensate line clog causing a major water leak also increases dramatically. A system that should have lasted 15 years or more may fail in as little as 7 to 10 years without proper care. Ultimately, skipping maintenance costs you far more in high energy bills, poor air quality, and expensive repairs than the maintenance itself would have.
