Key Takeaways


  • Regular cleaning improves aircon efficiency and lifespan

  • Safe cleaning requires proper tools and preparation

  • Both interior and exterior components need attention for optimal performance


Understanding Your Mitsubishi Aircon


Your Mitsubishi air conditioner is a complex system with many parts, including the indoor unit and the condenser unit, which are critical components. Knowing how it works and why cleaning matters will help you keep it running well.


Anatomy of Your Air Conditioner


Your Mitsubishi aircon has several key parts. The outdoor unit contains the compressor and condenser coil.


Inside, you’ll find the evaporator coil and air handler. The air filter traps dust and dirt. It’s usually behind the front panel. The evaporator coil cools the air. It sits behind the filter. The fan coil unit (FCU) plays a crucial role in distributing the cooled air throughout the indoor space.


Blower fans move air through the system. They can get dirty over time. The fan motor is essential for the operation of the blower fans, ensuring they function efficiently by removing dust and debris. The drain pan collects water that forms during cooling. It connects to a drain line to remove moisture.


Your remote control lets you adjust settings. Some models have smart features for easy use.


Importance of Regular Cleaning


Clean air conditioners work better and use less energy. Dirt and dust can reduce your Mitsubishi aircon energy efficiency.


A dirty filter forces the system to work harder. This uses more power and can lead to breakdowns. Clean filters help your air stay fresh and healthy.


Dirty coils can’t transfer heat well. This makes your AC less efficient. Regular cleaning helps prevent mold and bad smells.


A clogged drain line can cause water damage. Keeping it clear stops leaks and protects your home.


Clean units last longer. Regular aircon maintenance not only extends the lifespan of the unit but also ensures optimal performance. You’ll have fewer repairs and lower bills. Plus, you’ll breathe cleaner air in your home.


Safety First: Preparing to Clean Your Aircon


Before you start cleaning your Mitsubishi aircon, it's crucial to prioritize safety. Taking the right precautions will protect you and your unit.


First, turn off your aircon completely. Find the power switch on the outdoor unit and flip it to the "Off" position. For extra safety, disconnect the power supply at the circuit breaker.


Gather these supplies before you begin:


  • Soft brush or vacuum cleaner

  • Mild detergent

  • Clean cloth

  • Spray bottle with water

  • Protective gloves


Make sure you have a stable ladder or step stool if you need to reach high places. Wear comfortable clothes that allow easy movement.


Unplug the unit to prevent any electrical accidents. This step is vital for your safety and ensures no cool air is wasted during cleaning.


Before opening any panels, consult your Mitsubishi aircon manual. Different models may have varying panel locations and opening methods.


Remember to work in a well-ventilated area by opening windows and doors for fresh air to enter.


How to Clean Mitsubishi Aircon: Gathering Essential Cleaning Tools

Before you start cleaning your Mitsubishi aircon, you'll need to gather the right tools. Having the proper supplies will make the job easier and more effective.


Basic Cleaning Supplies


To clean your aircon, you'll need some common household items.


Grab a soft cloth or microfiber towel for wiping surfaces. You'll also want a spray bottle filled with warm water and mild detergent. This simple solution works great for most cleaning tasks.


Don't forget a vacuum cleaner with brush attachments. It's perfect for sucking up loose dust and debris.


A small brush, like an old toothbrush, is handy for scrubbing hard-to-reach spots.


Lastly, keep some paper towels or rags nearby. You'll use these to make sure the components are completely dry.


Specialty Tools for Aircon Cleaning


For a thorough clean, you might need some specific tools.


A fin comb helps straighten bent cooling fins on your aircon’s coils. You can find these at most hardware stores.


A coil cleaning brush is another useful tool. It has long, flexible bristles that can reach deep into the coils to remove dirt.


Consider getting a pump sprayer. It’s great for applying cleaning solutions evenly across large areas. A digital multimeter can help you check electrical connections if needed. An air blower is also essential for thorough cleaning and removing dust from the air conditioning unit.


Lastly, don’t forget safety gear like gloves and safety glasses to protect your hands and eyes.


Exterior Cleaning: Starting with the Basics


Keeping your Mitsubishi aircon's exterior clean is key to its performance. A clean unit runs more efficiently and lasts longer. Let's look at how to tackle the outdoor unit and its surroundings.


Wiping Down the Outdoor Unit


Start by turning off your aircon at the main power switch. This keeps you safe while cleaning.

Next, grab a soft cloth and some mild soap. Mix the soap with warm water in a bucket.


Gently wipe down the unit’s exterior with your soapy cloth. Pay extra attention to the fins and coils. The condenser unit, which houses various components including the compressor, plays a crucial role in the overall functionality of your air conditioning system. These parts can get very dirty. Be careful not to bend the fins as you clean.


For stubborn dirt, use a soft brush. Don’t use harsh chemicals or pressure washers. These can damage your unit. After cleaning, rinse with clean water and let it dry completely.


Cleaning the Aircon Surroundings


The area around your outdoor unit needs attention too.


Start by removing any debris like leaves or twigs. Use a broom or a leaf blower for this task.


Trim back any plants growing too close to the unit. Aim for at least 2 feet of clear space on all sides. This helps air flow freely around the unit.


Check for any oil stains on the ground near the unit. This could mean a leak. If you spot any, it's best to call a pro.


Lastly, make sure the unit is level. If it's tilted, it might not drain properly. You can use a level tool to check this. If it's not level, you may need to adjust its base.


Interior Deep Clean: Filters and Fins


Cleaning the interior of your Mitsubishi aircon is key for top performance. Focus on two main areas: the air filters and the evaporator coils with fins. These parts need regular care to keep your unit running smoothly.


Removing and Cleaning the Air Filters


Start by turning off your Mitsubishi air conditioner. Open the front panel and gently remove the filters.


You'll usually find two filters inside.


Cleaning these filters is simple:


  1. Shake off loose dust outside

  2. Vacuum the filters to remove more dirt

  3. Wash with warm, soapy water

  4. Rinse thoroughly

  5. Let the filters air dry completely


For stubborn grime, use a soft brush. Don't use harsh chemicals. They can damage the filters.


Put the dry filters back in place. Make sure they click into position. Clean filters help your AC work better and use less energy.


Care for the Evaporator Coils and Fins


The evaporator coils and fins need attention too. They're behind the filters and can collect dust over time.


To clean:


  1. Use a soft brush to remove dust from the coils

  2. Spray with a coil cleaner made for air conditioners

  3. Let it sit for a few minutes

  4. Rinse gently with water


Be careful with the fins. They're delicate and bend easily. If you see bent fins, use a fin comb to straighten them.


Dealing with the Drainage System


The drainage system is key to your Mitsubishi aircon's performance. A clean system prevents water leaks and keeps your unit running smoothly. Let's look at how to check and clear the main parts.


Inspecting the Drain Pan


Start by looking at the drain pan. Turn off your aircon and open the front panel. Find the drain pan under the evaporator coils.


Check for cracks or damage. A broken pan can cause water leaks, so you'll need to replace it if you see any.


Look for standing water or gunk. This can lead to mold and bad smells. Use a cloth to wipe out any water. For stubborn dirt, mix warm water and mild soap.


Clean the pan thoroughly. Rinse with clean water and dry completely before closing the unit.


Unclogging the Drain Line


The drain line carries water away from your aircon. When it’s clogged, water backs up and leaks. Here’s how to clear it:


  1. Find the drain line exit outside your home.

  2. Attach a wet/dry vacuum to the line.

  3. Turn on the vacuum to suck out clogs.

  4. If that doesn’t work, try flushing with a vinegar solution.


Mix equal parts water and vinegar. Pour it into the drain pan slowly. This helps kill mold and break up clogs. Ensure that the drain hose is functioning correctly and use white vinegar to clear it if issues are detected.


For tough blockages, use a pipe cleaner. Gently push it through the line to remove debris. Be careful not to damage the pipe.


After cleaning, run water through to check for good flow. If water drains freely, you’ve fixed the problem.

Then turn on fan mode before you head out to help the air con unit dry completely before reassembling.


Reassembling Your Aircon After Cleaning

Now that you've cleaned your Mitsubishi aircon, it's time to put it back together. This step is crucial for your unit's proper functioning.


Start by reinstalling the blower. Carefully place it back into position and secure it tightly.


Next, reattach the drain tray. Make sure it's level to prevent water leakage.


Replace the base panels. Align them correctly and fasten all screws.


Don't forget the air filter! Slide it back into place. A clean filter helps your aircon run more efficiently.


Finally, put the cover back on. Double-check that it's securely fastened.


Here's a quick checklist to ensure you haven't missed anything:


  • Blower reinstalled and secured

  • Drain tray reattached and level

  • Base panels replaced and screwed in

  • Air filter inserted

  • Cover securely fastened


Take a moment to wipe down the exterior of your aircon. This gives it a fresh, clean look.


Turn on your aircon and let it run for a few minutes. Listen for any unusual noises and check for proper cooling. If everything seems good, you've successfully reassembled your Mitsubishi aircon!


Maintaining Aircon Performance Post-Clean


Keeping your Mitsubishi aircon running smoothly after cleaning is key. Regular upkeep and monitoring help ensure your unit stays efficient and effective.


Scheduling Regular Maintenance


Set up a cleaning schedule for your Mitsubishi aircon. Clean the filters every two weeks to keep the air fresh. Vacuum dust from vents monthly.


Book a professional aircon servicing appointment yearly. They’ll inspect parts you can’t reach, which helps catch small issues before they become big problems. It's also important to clean the fan coil to ensure performance and address potential issues such as noise and bad odors from your aircon unit.


Keep a log of your maintenance tasks. Note the dates and what you did. This helps you stay on track and spot patterns in your aircon’s performance.


Consider setting reminders on your phone. This way, you won’t forget important cleaning dates.


Monitoring Aircon Performance


Pay attention to how your aircon works day-to-day. Listen for odd noises or changes in airflow, as these could signal a problem.


Check your energy bills regularly. A sudden spike might mean your aircon is working harder than it should.


Feel the air coming from your vents. It should be cool and crisp. If it's not, your aircon might need attention.


Use a thermometer to check room temperature. If it's not reaching the set temperature, your aircon might need a tune-up.


Watch for water leaks or ice buildup, as these are signs that something's wrong. Call a professional if you spot these issues.


Final Thoughts


Cleaning your Mitsubishi air conditioner is easier than you might think. With the right tools and a bit of know-how, you can keep your unit running smoothly by cleaning the components such as the heat exchanger, Mitsubishi Starmex aircon blower, and filters, you can ensure efficient performance and prolong the unit’s lifespan.


In such cases where issues persist despite cleaning, consult a professional to address more complex problems. With proper care, your aircon will provide cool, refreshing air for years to come!


Remember to clean your filters regularly. This simple step can make a big difference in your air quality and energy bills.


Don't forget about the outdoor unit! Keeping it free from debris will help your system work better.


If you're ever unsure, it's okay to call a pro. They can handle the trickier parts of maintenance.


By following these steps, you're not just cleaning - you're extending the life of your air conditioner. That means more comfort for you and less money spent on repairs.


Keep up the good work! Your clean, efficient Mitsubishi air conditioner will thank you with years of cool, crisp air.
