10 Maintenance Tips to Keep Your Wall Mounted Split AC Running Smoothly

Picture this: It's a scorching summer day, and you step into your home, seeking refuge from the sweltering heat. You rely on your wall-mounted split air conditioner (AC) to create an oasis of coolness, allowing you to escape the oppressive outdoor temperatures. 


But what happens if your trusty AC suddenly falters, leaving you in a sweat-soaked dilemma? It's a scenario no one wants to face. That's where regular maintenance comes into play. By incorporating a few simple yet effective maintenance practices, you can not only enhance the energy efficiency of your AC but also extend its lifespan. 


In this blog, we are going to walk you through ten invaluable tips that will keep it running smoothly, efficiently, and reliably. Let's get started on this adventure of AC maintenance mastery!


Clean and Replace Air Filters

Not only do clean air filters contribute to better indoor air quality, but they also help your wall-mounted split AC operate at its full potential. 


When the filters are clogged, the AC system has to work harder to push the air through, putting additional strain on the unit. To avoid these issues, it's essential to clean or replace the air filters regularly. 


Check the manufacturer's guidelines for specific recommendations, but as a general rule, aim to clean or replace the filters every 1-2 months. However, if you live in an area with high levels of dust or have pets, you may need to clean or replace them more frequently.


Check and Clean the Outdoor Unit


The outdoor unit of your wall-mounted split AC is exposed to the elements, making it susceptible to dirt, debris, and obstructions. Regularly inspecting and cleaning the outdoor unit is essential for optimal performance. 


Take a few moments to examine the unit and remove any accumulated dirt or debris using a soft brush or cloth. This simple task improves heat transfer, allowing your AC to cool your space more efficiently. By ensuring a clean and unobstructed outdoor unit, you'll not only enhance the lifespan of your AC but also enjoy maximum cooling comfort even during scorching summer days.


Clear the Condensate Drain Line


The condensate drain line is a crucial component of your wall-mounted split AC, as it ensures the removal of excess moisture from the system. However, over time, this drain line can become clogged with dust, mold, or algae, resulting in water leakage and potential damage to your AC unit. To prevent clogs and maintain optimal functionality, it's essential to regularly clear the condensate drain line. 


A simple and effective method is to create a mixture of water and bleach and use it to flush the drain line. This helps eliminate any accumulated debris and inhibits the growth of mold and algae. For detailed instructions tailored to your specific AC model, refer to the manufacturer's manual. 


Check and Adjust Thermostat Settings


Properly managing your thermostat settings can have a significant impact on your AC's performance and energy consumption. Instead of mindlessly cranking down the temperature, take a moment to find the sweet spot. 


Setting the temperature too low not only strains your AC but also leads to unnecessary energy waste. A smart solution is to invest in a programmable thermostat, which offers remarkable flexibility. These cutting-edge devices allow you to schedule temperature adjustments based on your daily routine. 


Imagine your AC automatically adjusting to a higher temperature when you're away but cooling down just in time for your return. It's a win-win situation, saving you energy and ensuring your comfort all day long.


Inspect Electrical Connections


Inspecting the electrical connections of your AC unit may sound like a mundane task, but it is a crucial step in maintaining the smooth operation of your cooling system. Think of it as giving your AC unit a thorough health check-up. Just like our bodies, electrical connections can suffer from wear and tear over time. 


You can prevent potential disasters like electrical malfunctions or even a complete system breakdown with this quick inspection. It's a small investment of time that can save you from bigger headaches down the line. So, grab your flashlight and give those connections a once-over. Your AC will thank you for it!


Clean the Evaporator Coil


Cleaning the evaporator coil is like giving your AC system a breath of fresh air. Over time, this coil can become a haven for dirt, dust, and even mold, which can hinder its efficiency and compromise your cooling experience. Imagine that every time you turn on your AC, it might work extra hard to push cool air through a dirty coil, like a marathon runner trying to sprint through the mud. 


By gently cleaning the coil with a soft brush or vacuum cleaner, you're removing those obstacles and allowing your AC to function at its best. If you're not confident in your cleaning skills, don't hesitate to reach out to professional maintenance services who can perform a thorough cleaning, ensuring your AC system stays in top-notch condition

Maintain Proper Clearance


Imagine going for a jog on a sweltering day while wearing a thick winter coat. You'd feel suffocated and unable to cool down, right? Well, the same goes for your wall-mounted split AC unit. To keep it running smoothly, it needs room to breathe!


Proper clearance is essential for optimal airflow and performance. Make sure there is at least two feet of clearance on all sides of your AC unit. This allows unrestricted air circulation, preventing any obstructions that could hinder its efficiency.


Regularly Inspect Fan Blades


The fan blades of your AC unit are like the unsung heroes working behind the scenes to keep your space cool. But just like any hero, they need your attention and care. Take a moment to inspect these mighty blades for any signs of wear and tear, dirt buildup, or misalignment. Over time, dirt and debris can accumulate, hindering airflow and compromising cooling efficiency. 


Gently clean the blades using a soft cloth or brush to remove any dirt or grime. If you spot any damage or notice that the blades are not aligned properly, don't hesitate to call in the professionals. They can swiftly replace the damaged blades and restore the superhero powers of your AC unit.


Schedule Professional Maintenance


Scheduling professional maintenance for your wall-mounted split AC is like giving it a spa day! Just like you deserve some pampering, your AC unit also deserves some TLC. By hiring a qualified technician for annual maintenance, you can ensure that your AC receives the VIP treatment it deserves. 


During the maintenance service, the technician will conduct a detailed inspection, clean out any accumulated dirt or debris, and lubricate the critical components. It's like a refreshing makeover for your AC, leaving it rejuvenated and ready to provide you with cool comfort all season long.


Stay Alert for Unusual Noises or Odors


Your AC unit communicates with you in a unique way, and it's important to listen. Pay attention to any unusual noises, vibrations, or odors emanating from your AC system. These can be warning signs of underlying problems. 


Maybe your AC starts humming like a distant orchestra or emits a strange odor that's not quite right. These symptoms shouldn't be ignored. They could indicate issues with the motor, compressor, or other critical components. 


When you notice anything out of the ordinary, don't hesitate to contact a professional technician. They have the expertise to diagnose the problem and resolve it promptly, ensuring your AC system continues to hum along smoothly, without any unsettling symphonies or unpleasant aromas.




Don't let your AC play hide and seek with your comfort! Give it the love and attention it deserves through regular maintenance. Follow these 10 tips to pamper your wall-mounted split AC and ensure it runs smoothly and efficiently. 


From cleaning air filters to scheduling professional maintenance, each step is a small investment in a refreshing indoor oasis. Remember, a well-maintained AC doesn't just keep you cool, it extends the lifespan of your unit and saves energy too. 


So, beat the heat and embrace the chill with a perfectly functioning AC that's ready to keep you cool for years to come!
