The air conditioning platform space is very narrow, so the workers can only finish the dismantling and assembling work by bending or crouching on the machine. Li Yusheng said that it usually takes forty minutes to one hour to install a new machine. However, compared to the various difficult circumstances he has met this year, what they encountered today is comparatively complex, and it would need more time.

When Li Yusheng finished installing the exterior unit, Yang Sheng and Li Ziyang began to install the indoor unit. After securing the holder, they lifted the machine up by ladder and hung it on the wall.
