7 tips for identifying the quality of central air conditioners, absolutely practical!

1. Appearance comparison

　　 Everyone shouldn't be surprised. "Take a machine by appearance" is very practical under certain circumstances. First of all, the surface of the electroplated parts should be smooth and flat, without scratches, peeling, and bottoming. The parts and pipelines must not collide or rub against each other. In addition, there must be no leakage, flow marks, bubbles, exposed primer layer, and uneven unevenness on the surface of the sprayed parts. The components are installed firmly and there is no looseness.

　　2, power on

　　 Detect the cooling and cooling effect of the air conditioner by energizing the equipment. If you buy air conditioners in summer, you can test the cooling effect. If you buy air conditioners in winter, you can test the heating effect. Adjust the wind speed, and you can also feel whether the change of the wind volume is normal.

　　3, vibration and noise detection

　　 As before, power on the air-conditioning equipment, keep the environment quiet, and listen to the sound of the air-conditioning compressor. If this is the case, it is felt that there are noises such as impact noise inside, or the external machine vibrates strongly during cooling, which proves that there is a problem with the quality of the central air conditioner and there is a safety hazard. Such an air conditioner is definitely not a choice.

　　4. Whether the function keys and knobs can be used flexibly

　　The central air conditioner uses a wire controller, remote control, or microcomputer controller. Try to use the buttons of each function to check the response speed and whether the buttons are brisk. There must be no problems such as slow response or button jams. If the above problem occurs, it must be replaced.

　　 5. Check the horizontal and vertical wind deflectors

　　 Regardless of whether it is a horizontal wind deflector or a vertical wind deflector, in the event of a power failure, you can adjust the position by fiddle, and it should be fixed at any angle without being unable to locate it. It cannot be so tight that it can't be dialed, nor can it be delivered and cannot be fixed.

　　 6. Try to disassemble the filter

　　 I believe everyone knows that the filter is a part of the air conditioner that is often disassembled and assembled. Because it needs to be taken off and cleaned from time to time, it is important to try to disassemble the filter to understand whether it is convenient to disassemble and assemble.

　　7, check the packing list and accessories are complete

　　Don't ignore this detail. The manual is your future operation guide. If you use the equipment correctly, you rely on it. The certificate is the official recognition of the product and must be seen. The warranty card and packing list are after-sales guarantees. If there is no one of these, then this product is not required.
