How can I get an AC installed at my home in Japan? -

I got an AC from one of my friends who is leaving Japan but am not able to get somebody who could install it. He got it installed by the company from whom he purchased it. Please suggest where can I find somebody to get it installed.

The company who installed it for him, might install it for you.

NO WAY YOU LIVE IN JAPAN?!?!?!?!?!?~!!??
