Service guarantee: the maintenance period for the same malfunctioned parts is 3-12 months。
Maintenance process: master comes to check air conditioner failure and informs clients of maintenance costs. Client accepts the offer and we repair it. If there's no maintenance value due to the failure or if the customer finds maintenance uneconomical, we'll only charge $30 for the test。
Air conditioners have been in use for many years and various malfunctions are possible. The following is a step-by-step presentation。
Air conditioning leak
Reasons for leakage of air conditioners and maintenance methods
Air conditioner maintenance masters experience air conditioner leaks every year. The reasons for the leak in the air-conditioning indoors are as follows:
1. Inadequate body set-up:
The interior is tilted and the pipeline is over-crossed。
Poor drainage pipes:
Drains are loose or curved into wave shapes, resulting in poor drainage。
3. Disclosures on pipes:
As the temperature-preserving material on the pipe is too poor or too thin, condensation occurs when refrigerants within the pipe pass。
4. Outdoor heat exchanger drops:
1) thermal exchangers are covered with dust, resulting in uneven heat exchange temperatures, while thermal exchangers produce droplets which fall outside the watercourse and drop into the interior。
2) the shortage of refrigerants in air-conditioning systems results in the freezing of indoor machines, and water droplets resulting from the melting of the ice do not drop directly into the sink。
In the event of a leak in an indoor aircraft, self-inspection may be conducted in accordance with the above. It would be better if it were handled by itself. If it cannot be solved by itself, air conditioners and maintenance technicians should be brought in in time。
The remote air conditioner won't open。
Method of maintenance of remotely operated air conditioners
1. Use of radio to detect whether a remote control device is used to respond. Power is being tested using tens of thousands of meters. The power measured in the remote receiver module is normal. However, at the time the remote control was launched, there was no remote signal voltage on the output point of the infrared receiver indicating that the infrared receiver might be welded or defective。
2. Remove the infrared receiver and replace it with a normal receiver. Following the tests, it was found that the remote control signal of the infrared receiver returned to normal output and the corresponding air conditioning remote control was restored。
3. Air conditioners were found to be in normal condition as a result of repeated remote-controlled switches, indicating that remote-opened malfunctions due to infrared receiver failure have been eliminated。
Air-conditioning fluorine leak
How do you judge whether air conditioning leaks fluorine? 1. After 30 minutes of continuous operation of the air conditioner compressor, the air conditioner repairer or the user may use the hand to touch the condensed blinds behind the air conditioner. If the hand is not cold or hot, the compressor is still working, indicating that fluorine leakage or fluorine deficiency is likely。
2. Ten minutes after the opening, you should see that it is normal to cover the condensed water evenly on the evaporation unit (the part of the copper tube containing aluminium tablets for thermal exchange). If half does not, it may be fluorinated。
If the compressor is found to have been working since it was activated without vibration at the time of the shutdown, the compressor's self-vibration is greater than when the compressor was newly purchased and may be fluorine-induced acoustic。
Air conditioners are not cooled if:。
Refrigerant leakage
Line leakage
3. Refrigeration systems, air filters, vents and vents blocked
4. Disconnection of wires
5. Combustion units for compressors and fans
Maintenance methods for frequent failure of non-refrigerated air conditioners
There are two reasons why air conditioning cannot be cooled:
There may be a shortage of refrigerants。
2. The air conditioning has been clean for a long time. At this point, we can look at filters and radiators. If it's dirty, you can clean it first and see how it cools afterwards. If not, consider whether it was caused by the lack of refrigerants. At this point, the air conditioner repairer will need to measure first, to see how much is missing, to see if there is any leakage, etc., to make repairs and to add sufficient refrigerants。
The air conditioner repairer can do this by looking, listening, touching, measuring, etc. Check for air conditioners。
