AZ Landlord Seeking Bedroom Room Cooling Options

[Ximing Feng]

Hi everyone, Hope all is well with you! I just purchased my first rental. It is a triplex. Each unit is 773 sqft with 2 bed 1 bath. Each bedroom is around 135 sqft. Previous owner installed mini-split in the living room. It works fine. The problem is that, the tenant has to open the bedroom door in order to cool down the bedroom. It is very inconvenient and what would be the most cost efficient way to solve this?

• Window Unit?
• Another Mini Split in bedroom?
• Other?

Thank you very much!
