Hello everyone! Here is a question for you. What is the charge guarantee of central air conditioning maintenance in China at present? What is the actual cost?

The state has no relevant regulations. Do you do single maintenance service or annual maintenance plus inspection and maintenance service? If the calculation based on cold weather may still be inaccurate, it should be calculated manually. If the average worker is calculated manually according to one day 150, then you need at least 300 to 500 skilled workers to repair air conditioners, plus the taxes and profits given to you by the air conditioning company, as well as depreciation and freight charges for maintenance equipment. , each person needs at least 600 to 1000 per day. If monthly inspection and urgent repair are added, the maintenance of a single refrigeration unit should be around 5,000 yuan. If your cooling capacity is above1000 tons, it may be about 8000 to 10000 yuan. If the unit is larger, it is about 15000 yuan. The specific price will be determined according to your traffic situation, unit failure rate and operation problems. The filter element and lubricating oil of general consumables need to be replaced frequently, mainly depending on your use time. If you don't know much about the principle of air conditioning, it is recommended to use the manufacturer for maintenance. It may be more expensive, but it's more secure. Also, the manufacturer does not represent the installer, and the real manufacturer can use 1 14 to query. Personal advice, for reference only.
