And then there were the thermostats.
Growing up, my father was in the Army so we moved around a lot. It seemed like we never stayed in one place for more than a year. Every base was different and so were the houses we lived in. Most of the time we just lived in base housing. It was easier that way. Some bases had nice houses. Other houses were infested with mold and bugs and falling apart. Another thing that I found interesting were the HVAC systems in all of the different houses. Every single one of them had central heating and cooling. However, how well this heating and cooling was a total crap shoot. Some houses had new HVAC systems that were well maintained and worked well. Those were a rarity though. In most cases the HVAC systems were ancient, there was a lot of dust in the ductwork, and they broke down from time to time. I remember this one house where the furnace didn’t work. It only was lukewarm no matter how high you set the thermostat. In another house the air conditioner broke down 6 times in just under 2 years. Each time it broke down we had to wait over a week before it was fixed. And then there were the thermostats. We had dial thermostat or analog thermostats and no one was like the other. 75 degrees in one house was a much different temperature than 75 degrees in another house. I don’t know if that is because the thermostats weren’t calibrated or if it had to do with the design of the house.
