SLA Clause for fixing appliances in property?

[Emory Clayton]

Do yall include a clause in your rental contract that states that when an appliance breaks, that you will have it resolved in a certain time frame? Or do you have a clause that states that there is NO SLA for fixing an appliance due to uncontrollable variables? I'm speaking from the perspective of this:

Tennant reports appliance isn't working. You or contractor/handyman come out and diagnose issue and order part. Obviously I don't have control over how long the part takes to get delivered. Tennant complains and wants a new appliance ordered because it has been "X" number of days since they reported the issue.

This is hypothetical. However I think I should have something in my rental agreement to handle this. Thanks as always.
