Air conditioning has now become an indispensable daily equipment for families, and it can be used in summer or winter.
However, if the air conditioner is not properly maintained and cleaned, not only will the efficiency of the equipment decrease, but it will even affect the health of family members. It is very important to know how to properly maintain your home air conditioner. Let’s take a look at how to maintain household air conditioners!
1. Clean the air conditioner regularly
Regular cleaning is the first step in maintaining the air conditioner. Clean the surface of the air conditioner with a damp cloth every month, and use a vacuum cleaner to remove dust and debris around the machine. If your air conditioner has a removable filter, it should be cleaned once a month. This prevents dust accumulation and ensures smooth air circulation.
2. Replace the filter regularly
The filter is an important component that prevents dust and other pollutants from entering the inside of the air conditioner. Depending on the frequency of use, the filter should be cleaned or replaced with a new one every month. Replacing the filter regularly ensures that the performance of your air conditioner is not affected while providing cleaner air.
3. Regularly check the condenser and evaporator
The condenser and evaporator are important heat dissipation components inside the air conditioner, but they are also susceptible to dust and dirt. Regular inspection of these parts and cleaning them will ensure the proper functioning of the air conditioner.
4. Use regular professional maintenance
Have professional technicians inspect the air conditioner at least once a year and perform necessary maintenance and cleaning. This ensures that the air conditioner is in optimal condition and reduces the chance of failure.
5. Pay attention to energy-saving use
In addition to regular maintenance, you should also pay attention to energy-saving use of air conditioners. When using an air conditioner, the room should be kept airtight to avoid wasting energy from the air conditioner. At the same time, choosing the right temperature and wind speed can also save energy.
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.

- 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.
