Tenants heat is out, what to do?

[Ryan Davis]

My tenants heat went out last night. Luckily, I have a home warranty. I called and the soonest they can get one of their contractors out there is Monday. The tenant is not happy about this with today being Thursday. I could call an emergency HVAC guy over to fix it, but then the cost would be out of pocket. 

Should I handle the situation myself out of pocket, or tell him he is going to have to wait? If I make him wait, how should I make the situation right, deduct some rent off? Whats your advice?
