Air conditioning systems are essential for comfort, especially in hot and humid climates. However, without proper maintenance, they can become inefficient, leading to higher energy bills, poor cooling performance, and even costly repairs. Regular maintenance is crucial to keeping your air conditioner in top shape. While professional servicing is recommended periodically, you can take several DIY steps to maintain your aircon unit.
In this guide, we will provide essential DIY aircon maintenance tips to help you improve the performance and longevity of your air conditioning system. If you ever need professional servicing, visit 7Days Aircon Servicing Pte Ltd for expert assistance.
Why DIY Aircon Maintenance is Important
Regular aircon maintenance has several benefits, including:
- Better Cooling Efficiency – Clean air filters and coils allow for smooth airflow and optimal cooling.
- Lower Energy Bills – A well-maintained aircon consumes less electricity.
- Extended Lifespan – Prevents wear and tear, reducing the likelihood of costly repairs or replacements.
- Improved Air Quality – Removes dust, allergens, and bacteria from the air.
- Prevents Costly Repairs – Identifies minor issues before they turn into major problems.
Now, let’s explore some effective DIY aircon maintenance tips that you can perform at home.
- Clean or Replace Air Filters Regularly
Why It’s Important:
Air filters trap dust, dirt, and other airborne particles, ensuring clean airflow. Over time, clogged filters reduce airflow and force the aircon to work harder, reducing efficiency.
How to Clean the Air Filter:
- Turn off the aircon and unplug it for safety.
- Locate the air filter (usually behind the front panel of the indoor unit).
- Remove the filter carefully.
- Wash the filter using mild detergent and water. Rinse thoroughly and let it dry completely.
- Reinstall the filter and turn the aircon back on.
Frequency: Clean filters every two weeks and replace them every 3-6 months (or as recommended by the manufacturer).
- Clean the Aircon Coils
Why It’s Important:
Over time, dirt and dust accumulate on the evaporator and condenser coils, reducing heat absorption and leading to poor cooling performance.
How to Clean the Coils:
- Turn off the power to the aircon unit.
- Open the indoor unit panel and locate the evaporator coils.
- Use a soft brush or a vacuum cleaner to remove loose dirt.
- Spray a coil cleaner (available in hardware stores) and let it sit for the recommended time.
- Wipe the coils clean with a damp cloth.
- For outdoor condenser coils, use a hose or coil cleaner to remove debris.
Frequency: Clean the coils every 3-6 months to ensure optimal cooling performance.
- Check and Clean the Aircon Drainage System
Why It’s Important:
A clogged drainage system can cause water leakage, leading to mold growth and damage to your aircon unit.
How to Clean the Drainage System:
- Locate the drain pipe (usually found at the back of the indoor unit).
- Use a thin brush or pipe cleaner to remove dirt and mold buildup.
- Pour a mixture of warm water and vinegar into the drain to flush out clogs.
- Ensure the drain pipe is free from blockages.
Frequency: Check and clean the drainage system every 2-3 months.
- Inspect the Refrigerant Level
Why It’s Important:
Low refrigerant levels can cause inefficient cooling and higher electricity consumption. If you notice your aircon isn’t cooling as effectively, the refrigerant level may need to be checked.
How to Check:
- Look for ice buildup on the coils or refrigerant lines.
- Check for hissing sounds, which may indicate a refrigerant leak.
- If the aircon is not cooling effectively, it may need a refrigerant top-up.
Note: Do not attempt to refill refrigerant yourself. If you suspect low refrigerant levels, contact 7Days Aircon Servicing Pte Ltd for professional assistance.
- Keep the Outdoor Unit Clean and Unobstructed
Why It’s Important:
The outdoor condenser unit plays a crucial role in expelling heat from your home. If it is covered in dirt or obstructed by objects, it can affect your aircon’s efficiency.
How to Maintain the Outdoor Unit:
- Turn off the power to the unit.
- Remove leaves, dirt, and debris from the condenser fins.
- Use a soft brush or a vacuum cleaner to clean the surface.
- Ensure at least 2 feet of clearance around the unit for proper airflow.
Frequency: Clean the outdoor unit every 3-4 months.
- Check for Air Leaks and Insulate Ducts
Why It’s Important:
Air leaks reduce cooling efficiency and increase electricity consumption.
How to Check:
- Inspect the aircon ducts and vents for leaks.
- Apply sealant or insulation to any exposed ducts.
- Ensure that doors and windows are properly sealed to prevent cool air from escaping.
Frequency: Check for air leaks every 6 months.
- Set the Right Temperature and Use Energy-Saving Modes
Why It’s Important:
Using energy-efficient settings helps prolong your aircon’s lifespan and reduce electricity costs.
Best Practices:
- Set the temperature to 25°C – 27°C for optimal energy efficiency.
- Use the timer function to turn off the aircon when not needed.
- Use energy-saving modes such as eco mode or sleep mode.
- Keep curtains and blinds closed during the day to prevent heat buildup.
When to Call a Professional
While DIY maintenance can help keep your aircon in good condition, some issues require professional attention. Contact 7Days Aircon Servicing Pte Ltd if you experience:
- Weak or no cooling despite regular cleaning
- Unusual noises or foul odors from the aircon
- Water leakage even after clearing the drainage system
- Higher-than-normal electricity bills
- Frequent system shutdowns
Conclusion
Regular aircon maintenance is essential for ensuring efficient cooling, lower energy bills, and a longer lifespan for your unit. By following these DIY aircon maintenance tips, you can keep your air conditioner in top shape and enjoy uninterrupted comfort.
