Air conditioning is the key to a comfortable life in summer, but problems with lack of cooling, water leakage or noise may affect your experience. Many problems can be solved with simple inspection and cleaning. This article will introduce the steps for air conditioning repair, common problem solving and maintenance suggestions to help you restore a cool home environment.
Why do you need to repair air conditioners?
- Improving efficiency: Cleaning the filter and condenser can restore air-conditioning performance and save electricity bills.
- Extended lifespan: Regular maintenance can avoid parts damage and reduce repair costs.
- Improve air quality: A clean filter can reduce dust and allergens.
Air-conditioning maintenance steps
- Check the power supply
Confirm whether the air-conditioning plug and switch box are normal. If the circuit breaker trips, check to see if any appliances are overloaded. - Clean the filter
Remove the air-conditioning filter, clean it with warm water and neutral detergent, dry it and put it back again. Clean every 1-2 months. - Check the condenser and drain pipe
Clean the dust on the outdoor unit condenser to ensure normal heat dissipation. Check whether the drain pipe is clogged and clear it with a thin wire. - Check the refrigerant
If the air conditioner is not cold, there may be insufficient refrigerant. Use a pressure gauge to check the amount of refrigerant, and ask a professional technician to replenish it if necessary. - Test operation
Turn on the air conditioner to confirm the air conditioner effect and whether there are any abnormal noises. If the problem persists, further inspection is required.
Common problems and solutions
- The air conditioner is not cold: Check whether the filter is dirty or the refrigerant is leaking.
- Water leakage problem: Clean the drain pipe, or check whether the indoor unit is tilted.
- Excessive noise: Check whether the fan blades or screws are loose, and add lubricating oil if necessary.
Maintenance recommendations
- Regular cleaning: Clean the filter and condenser once a quarter to maintain efficiency.
- Check the wires: Make sure the wires are not aged to prevent the risk of short circuits.
- Set the proper temperature: Set 26-28°C to save energy and reduce parts wear.
When to seek professional assistance?
If it involves refrigerant replenishment or internal parts replacement, it is recommended to contact a professional air-conditioning technician. Handling it yourself may result in danger or damage.
Conclusion
Air conditioner repair and maintenance can ensure cooling and energy saving. Through simple cleaning and inspection, you can extend the life of your air conditioner. Check your air conditioner now and enjoy a cozy summer!
New knowledge on air-conditioning power consumption and Taiwan climate maintenance regulations in recent years (2025-2026 current situation)
With the high temperatures in summer breaking historical records and the adjustment of electricity price structure in recent years, the latest statistics from the Energy Administration of the Ministry of Economic Affairs show that air-conditioning equipment accounts for more than 47% of residential electricity consumption in summer. Many people mistakenly believe that if the air conditioner is not cold, they only need to "replenish the refrigerant." However, in fact, refrigerant is not naturally consumed during normal operation in a closed circuit. If the refrigerant is insufficient, it means that there are micro leaks in the copper pipes or joints. Simply replenishing the air conditioner will only treat the symptoms but not the root cause. Refrigerant leakage will aggravate the high temperature overload of the compressor and shorten its service life.
According to Taiwan's standard operating specifications for air-conditioning projects, it is recommended that professional technicians with a refrigeration and air-conditioning decoration technician license perform "full machine high-pressure water washing and evaporator deep sterilization" every 1 to 2 years for detached air-conditioning indoor units. Especially in the humid summer in the Shuangbei Basin, the air drum and water collection tray are easy to breed black mold and jelly-like biofilm. This is also the main reason for the sour smell in the air-conditioning outlet and the backflow of the drainage pipe. Regular maintenance can maintain CSPF (Air Conditioning Seasonal Performance Factor) level one energy efficiency level, which can save an average household 15% to 20% of air conditioning electricity bills every year.
Autonomous simple maintenance vs professional maintenance safety red line
- Homeowners can do by themselves: Remove and clean the nylon filter regularly every 2 to 3 weeks (rinse with clean water and dry in a cool place, do not expose it to the sun to avoid deformation and embrittlement); clean the air outlet blades of the indoor unit with a dry cloth; check whether there is any accumulation of debris within 50 cm around the outdoor unit that hinders heat dissipation.
- Professional technicians must be entrusted according to regulations: Refrigerant pressure testing and leakage repair welding, high-pressure cleaning of indoor unit air drums and aluminum fins with liquid chemicals, reset of the drainage slope of hidden cold water pipes in the ceiling, and 220V dedicated power circuit configuration and leakage circuit breaker replacement.
