What should customers prepare before washing the air conditioner?

The customer should clean up the site in advance and reserve enough space for the master to clean, so as to avoid the furniture being splashed with sewage during cleaning. For example, cleaning the window-type air conditioner requires disassembling the body, and then moving the air conditioner to an open place for cleaning, so Before the air conditioner comes to the door, it is necessary to clear the sundries under the air conditioner and arrange a place suitable for cleaning the window-type air conditioner.

Why does the air conditioner still leak water after draining the water pipe?

There are various reasons that can cause water leakage from the air conditioner, including too much dirt accumulated in the air conditioner, problems with the installation of drain pipes, etc. The solution includes thoroughly cleaning the inside of the air conditioner to prevent dirt from flowing into the pipes.

What is the difference between a window-type air conditioner and a split machine?

To clean a window-type air conditioner, you need to disassemble the air conditioner parts first, then disassemble the whole window-type air conditioner , and then use the special cleaning agent for cleaning the window-type air conditioner to clean the inside and outside of the fuselage; as for cleaning the split type air conditioner, it is not necessary To disassemble the unit, you only need to take off the parts of the air conditioner first, and then do on-site protection such as waterproof plastic bags to carry sewage, and then start cleaning the split air conditioner.

Does cleaning the split type air conditioner include the outdoor unit?

In consideration of safety, when the master cleans the split type air conditioner, he only cleans the indoor unit, not the outdoor unit.
