Converting from window units to central AC in small multi family

[Kurt Jones]

Hello everyone, I have recently started to transition out of single-family and into multifamily investing. One of the buildings I have acquired is an eight unit old-school apartment complex. In starting to bring it up to speed, I am considering replacing the old window units with central AC. These units are small one bedroom approximately 600 ft.² units so it would not require huge AC units to cool them. Does anyone in this forum have any experience in similar projects? I'd love to hear of any pitfalls or lessons learned from others on the board. Thanks! Kujo
