1. Clean the indoor and outdoor units of the air conditioner.
This is the most basic way to protect the air conditioner. Cleaning air conditioning equipment can improve efficiency, increase air circulation, eliminate odor and prolong equipment life. The cost of cleaning the indoor unit and outdoor unit of an air conditioner is usually between 300-500 yuan.
2. Replace the capacitor and motor
If the air conditioner is hot and cold alternately, there is noise or it will automatically stop after a while, this may be a signal that the capacitor needs to be replaced. The cost of replacing a capacitor is usually 150-300 yuan. If you need to replace the computer, the cost is relatively high, which is estimated to be around 300 yuan.
3. Replace the refrigeration system
If the refrigeration system of the air conditioner fails, it may be necessary to replace the condenser, evaporator or other components. The maintenance cost of refrigeration system will be higher, usually above 1000 yuan, and the price will vary according to the specific situation.
4. Replace the compressor and electric control board
If the air conditioner has a long service life or problems often occur, it is necessary to replace the compressor or the electric control board. This is a complicated maintenance process, and the price is also very high, generally more than 2000 yuan, or even more.
In a word, the maintenance cost of air conditioner depends on the severity of the problem and the type and scale of parts that need to be replaced to some extent. If you are not sure about the problem of the air conditioner, it is recommended to find professional maintenance personnel to check it to ensure that the problem is solved accurately and avoid additional maintenance costs.
