My sister has a triple story house with a lot of space.
The third floor of her house is essentially a lofted bedroom, but it’s really large and has a great view from the window.
Whenever our entire family stays at her house, I sleep in the third story bedroom. For the most part, it’s a really comfortable space. However, there is one thing that really bothers me while I’m sleeping there, and it’s the heat! Even though there are three levels to the house, there is only one HVAC system and one central thermostat. No matter how low she sets the thermostat temperature, the third floor is always super hot. All the heat rises, especially during the evenings while I’m trying to sleep. There is a small AC unit on the window, but it’s loud and only cools a small radius directly in front of it. On more than one occasion, I’ve had to sleep on the floor in front of the window AC unit. I’ve complained about the lack of cool air to my sister on several occasions, but she’s never done anything about it. It wasn’t until I brought up ductless mini split systems that she finally took action. I guess she liked the fact that ductless mini split systems didn’t need to connect to existing ductwork, because she had one installed recently! She told me how affordable it was and how effective it was at cooling the third floor. She also said that she loved how she could turn the ductless mini split system on and off depending on when she’d be using the third floor bedroom.
