A/C broke, tenants want to be compensated, need advice

[Alejandro B Yoon]

I currently manage my mother's property that is using a rent by the room strategy. Last week the A/C in our unit fried from a power surge and required a new thermostat and tablet piece. After back and forth with the technician and 2 trips to the home, I finally have the guy fixing the A/C today on Friday. 7 days after it broke.

In the meantime, the tenants have been complaining daily and I have been telling them that the technician keeps postponing his date to fix since we needed to order a part. 

They say it got so bad they had to sleep in a hotel/out of the house for a night or two. Multiple tenants want me to either reimburse for the hotel stay or reduce their rent for the following month. What should I do?
