Exacatly my 30k install cost for 2 ACs were high already after all works they like so it will be 15k extra I am like WHUT but oh well it's japan next time going to rent tools for 5k and materials for like 10k max.

My unit CS-229CFR with tax I think was 42k or similar and model to make it smart was +5k so it was still cheaper than cheapest smart model
