Mitsubishi AC service and repair is very important to keep your air conditioner running well, especially during hot weather. If you do not clean your split AC properly, it can lead to blockages behind the evaporator coil. This can cause water to leak from the blower or even from behind the wall, away from the proper drain area. That’s why ac maintenance in dubai, especially of the drain line and evaporator coil, is necessary for every Mitsubishi split AC unit.
In this blog post from AirChill AC Maintenance and Duct Cleaning, we’ll guide you through the steps of cleaning a split AC, explain why each part is important, and help you understand when it’s time to call a professional for Mitsubishi AC service and repair.
Why Regular AC Cleaning Is Important
Many people only think about their AC when it stops working. But just like a car needs oil changes, your AC needs regular cleaning and servicing. Especially with Mitsubishi split AC systems, keeping everything clean will:
- Improve cooling performance
- Reduce energy bills
- Prevent water leaks
- Extend the life of the AC unit
- Improve indoor air quality
Dust, mold, and algae can build up inside the system. If the evaporator coil is blocked, the cold air can’t move properly. This can make your AC leak water or blow warm air. That’s where Mitsubishi AC service and repair makes a big difference.
Tools You’ll Need for Split AC Cleaning
Before you begin, here are some tools you should gather:
- Soft brush or toothbrush
- Fin comb (optional, for straightening fins)
- Mild soap or coil cleaner
- Bucket or drain pan
- Water spray bottle
- Vacuum cleaner (with a brush attachment)
- Screwdriver (for opening the panel)
- Safety gloves and eyewear
If you don’t feel confident, it’s better to call AirChill AC Maintenance and Duct Cleaning for a full professional cleaning.
Step-by-Step Guide: Cleaning a Mitsubishi Split AC
1. Turn Off the Power
Safety first! Always turn off the AC unit from the main power switch or breaker box before doing any work.
2. Clean the Front Panel and Filters
Open the front panel gently. Remove the dust filters.
- Wash the filters using mild soap and warm water.
- Let them dry completely before reinstalling.
- Wipe the front panel using a damp cloth.
Dirty filters reduce airflow and make the AC work harder, wasting energy.
3. Inspect and Clean the Evaporator Coil
The evaporator coil is where the air cools down. Dust and mold can block it and even form behind the coil.
Warning: Blockages behind the evaporator coil can cause water to leak through the blower or behind the wall, not just from the usual drain area. This can damage your walls or furniture.
To clean:
- Use a soft brush or a coil cleaner spray.
- Spray lightly and wait for the foam to lift the dirt.
- Gently wipe or rinse it off.
- Be careful not to bend the fins.
If dirt is deeply stuck, it’s time to schedule a Mitsubishi AC service and repair from experts like AirChill AC Maintenance and Duct Cleaning.
4. Check the Drain Line
The drain line removes water from the AC. If it’s blocked with dust, algae, or mold, the water will back up and leak.
How to clean the drain line:
- Locate the drain pipe (usually a white or clear hose).
- Use a vacuum or a wet/dry vac to suck out clogs.
- Pour a mixture of water and vinegar to kill mold.
- Rinse with clean water.
This is one of the most important steps in Mitsubishi AC service and repair. A blocked drain is a common reason why ACs leak.
5. Clean the Blower Wheel and Indoor Unit
The blower is what moves the air through your home. If it’s dusty, you may notice weak airflow or a musty smell.
- Carefully remove the blower wheel (if possible).
- Use a soft brush and cloth to clean it.
- Vacuum inside the blower housing.
- Wipe down the inside of the AC unit.
Note: Deep cleaning the blower may require disassembling the unit, which is best done by professionals at AirChill AC Maintenance and Duct Cleaning.
6. Clean the Outdoor Unit (Condenser)
The outdoor condenser unit helps remove heat from your home.
Steps:
- Remove leaves, twigs, and debris from around the unit.
- Open the top cover carefully.
- Use a soft brush or hose to clean the condenser coil.
- Avoid high pressure; it may bend the fins.
A dirty outdoor unit can overheat and affect the performance of your Mitsubishi AC.
7. Check the Refrigerant Level
If your AC isn’t cooling properly even after cleaning, it may have low refrigerant levels.
- Check for ice buildup on the coil or pipes.
- If refrigerant is low, only a licensed technician should handle it.
Low refrigerant is a key reason to book Mitsubishi AC service and repair.
Common Problems If You Don’t Clean Your AC
Neglecting regular maintenance can cause:
- Water leakage through the wall or blower
- Poor cooling and weak airflow
- Higher electricity bills
- Bad odor and mold growth
- Expensive repairs due to compressor failure
Blocked evaporator coils are especially dangerous. Dirt builds up not just on the surface, but also behind the coil, which you can’t see. This can cause water to bypass the drain tray and leak from unexpected areas.
How Often Should You Clean a Mitsubishi Split AC?
Here’s a simple guide:
| Component | Cleaning Frequency |
|---|---|
| Air Filters | Every 2–4 weeks |
| Evaporator Coil | Every 3–6 months |
| Drain Line | Every 3–6 months |
| Blower and Fan | Every 6–12 months |
| Outdoor Condenser Coil | Every 6 months |
If you live in a dusty area or use your AC daily, you may need more frequent cleaning.
