I am a landlord, yes. I am also a tenant and have been a tenant longer than I have been a landlord. The home I am in actively has no heat. I would never expect my landlord to magically fix a problem on Christmas Day. That is completely unrealistic. I set up my heaters, discussed a game plan with the landlord, and have set my expectations accordingly. It’s not their fault that no contractor in the area is available on a major holiday.
