For Nagoya homes, we discuss aircon cleaning, weak cooling, water leaks, refrigerant-leak inspection, installation, removal and relocation in one place. Photos of the model, indoor unit, outdoor unit and the surrounding site help clarify whether cleaning, inspection or installation work is the right starting point.

A musty smell does not always mean the same work as weak cooling, and a wall leak near the piping is not always a drain issue. Our Nagoya guides separate the visible symptom from the inspection points so the scope can be discussed before work is arranged.
For moldy odor, visible dark buildup, self-cleaning units and outdoor-unit cleaning discussions.

Minami Ward, Nagoya, Aichi
A case in Nagoya's Minami Ward where water appeared from the interior wall rather than the aircon unit. Neither side of the wall penetration had been sealed, allowing humid air to enter and condense around the cold piping.
Read the case guideA 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.
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.
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.
Tell us the model, symptoms, preferred date and your Nagoya address area. We will confirm the situation and explain the estimate process.
