Nagoya Minami Ward: indoor wall leak caused by missing putty around an aircon pipe hole

What should I share before asking about aircon cleaning in Nagoya?
A photo of the model label, the outlet, the room-side unit, outdoor unit and the installation surroundings makes the first discussion clearer. Tell us whether the concern is odor, visible buildup, weak airflow or another symptom.
My aircon runs but does not cool. Is it always a refrigerant leak?
No. Filter condition, operating mode, outdoor-unit behavior and installation conditions can also matter. If refrigerant is low, flare joints and piping may need inspection before a refill is considered.
Can installation and removal of an old unit be discussed together?
Yes. Share the new model if known, photos of the indoor and outdoor locations, the outlet and breaker-panel area, and whether the old unit needs removal or disposal.
