What's Your Take on Window A/C Units?

[Derek Luttrell]

Hi All, 

I'm under contract on my first buy and hold, and there isn't any central A/C (not too uncommon here in Chicago.) For landlords who have similar units, do you always provide the a/c units come summertime and go install them yourself, or do you put in your lease that the tenants are responsible for their own cooling methods? Every room in the property also has a ceiling fan. 

I feel like there's a good amount of liability if you allow a tenant to install their own unit, and if I were the tenant I know I would appreciate the landlord taking care of something like this for me. With that comes added time and cost for the landlord, though, so I'm curious about what the status quo is.
