Installing and Arranging Your Air Conditioning System
When using air conditioning in a Japanese rental property, the first thing to verify is whether the unit already has an air conditioner installed. Many properties provide space for an outdoor unit, but installation of the indoor unit falls on the tenant. If you need to install a new air conditioner, always check your lease carefully and confirm with the property management company whether wall penetration is allowed and whether there are any issues with outdoor unit placement.
If the property already has an air conditioner, make sure your lease specifies "air conditioner included." Cleaning responsibilities and repair cost liability vary depending on contract terms. Older units are inefficient and costly to run, so upgrading to a new one may be worth considering.
