These are the tools I gathered around May of last year to start air conditioner cleaning. I've only used them about 10 times.

In the 3rd photo, the packing on the water supply hose deteriorated because I left it attached, making it difficult to build pressure. I wrapped it with sealing tape, and it worked without issue. However, if you're concerned, you can likely replace this part with one purchased at a home improvement store.

The storage bag is simply a large bag for camping gear. I've placed a suitably sized gardening tray inside to prevent leaks if water spills. Adding rags or towels would provide even more security.

The busy season for air conditioner cleaning is approaching. The air conditioner cleaning cover has already been sold, so with this set and a cover, you can start air conditioner cleaning immediately.
The rags and microfiber towels I used have also been washed thoroughly and can be included if needed. Please let me know when you purchase if you would like them.

Would this be suitable for someone looking to start air conditioner cleaning, or for a professional who needs a spare set?
