Is the air conditioner not cold? Take this 5-minute quick test first
The summer in Taipei and New Taipei is hot and muggy, and the sudden lack of air conditioning is really worrying. However, most conditions can be initially determined through simple inspections to avoid unnecessary maintenance expenses. Please confirm in order:
❄️ 1. Remote control setting confirmation
Check whether the mode is mistakenly set to "air supply" or "dehumidification", whether the temperature setting is too high (recommended 26~28℃ for the most power-saving), and confirm that the timer function is not accidentally activated.
❄️ 2. Filter cleanliness check
Remove the indoor unit filter. If there is obvious dust accumulation or mold, it will seriously affect the air volume and cooling efficiency. It is recommended to clean it every 2 weeks, rinse with water and dry in the shade.
❄️ 3. Heat dissipation condition of the outdoor unit
Observe whether there is accumulation of debris, cover by plants, or dust on the cooling fins around the outdoor unit. Poor heat dissipation will cause the compressor to be overloaded and the cooling effect will be greatly reduced.
❄️ 4. The refrigerant pipe is frosted or dripping abnormally
If the copper pipe is severely frosted or the indoor unit is dripping a lot, it may mean that the refrigerant is insufficient, the drainage pipe is blocked or the installation is tilted, and professional maintenance is required.
❄️ 5. Confirmation of electrical load and voltage
If the voltage is unstable during peak power consumption periods, it may affect the starting efficiency of the air conditioner. You can observe whether other electrical appliances are abnormal at the same time, or contact Taipower customer service (1911) to check the regional power supply status.
Need a master: If there is still no improvement after cleaning, you may need to deep clean or replace the fan assembly
🔧 Problem 2: The air conditioner is running but the room temperature cannot drop
• Possible reasons: refrigerant leakage, compressor efficiency decrease, excessive indoor and outdoor temperature difference
• Self-treatment: close the doors and windows, draw the curtains to reduce the heat source, and confirm that the outdoor unit has sufficient cooling space
• A master is required: professional equipment is required for refrigerant detection and replenishment, do not add it by yourself
🔧 Problem 3: Odor, noise or water leakage
• Possible reasons: Internal mold, blocked drain pipe, installation tilt or loose parts
• Self-handling: Turn on the "air supply" mode regularly to dry the interior, and check whether the drain pipe outlet is smooth
• A master is needed: professional skills and tools are required for disassembly, cleaning, correction and installation or replacement of parts
Do it yourself vs. "hire a master" cost-benefit analysis for air-conditioning cleaning
🧼 DIY basic cleaning
• Cost: Filter cleaner costs about 100 to 300 yuan, and tools (soft brushes, spray bottles) can be reused
• Suitable for: monthly routine maintenance, filter and housing cleaning, air outlet dust removal
• Limitations: unable to clean the internal evaporator, wind wheel and refrigerant system, the effect of deep soiling is limited
👨🔧 Professional deep cleaning
• Cost reference:
- Window air conditioner: 2,500~3,500 yuan/unit (small tonnage)
- Split air conditioner: 3,000~5,000 yuan/unit (including indoor and outdoor units)
- Annual maintenance plan: Some operators offer 2 cleaning discounts, which is more cost-effective in the long term
• Advantages: Use professional equipment (high-pressure cleaner, disinfectant spray) to remove internal mold and slime, restore air volume and cooling efficiency, and detect potential faults
💡 Recommended strategy: Clean the filter by yourself every month, and commission a professional deep cleaning once a year before summer, taking into account both effectiveness and cost.
