When I lived with my parents, I kind of used the a/c unit recklessly, and it didn’t matter what temperature it was outside, or how much it cost, if I was in the mood for heating or cooling, I was getting it.
Thankfully, my parents were really patient and relaxed, and as long as I didn’t do anything to actually damage the air conditioning system unit, such as overwork it, they didn’t mind much! When I moved out on my own, that completely changed once I realized how much heating and air conditioning bills can add up to. I started being a lot more conscious about how I was using the heating and air conditioning device, and started using it more wisely. I started to only use the a/c on absolutely overheated days or afternoons, and for the rest, I would use my ceiling fans in my home. On particularly overheated days, if I still didn’t want to use the cooling machine, then I would have a desk fan running and the ceiling fan. With those methods combined, it made a big enough difference where I didn’t have to use the a/c or oil furnace system. I did pretty much the same with my furnace unit, unless it was an incredibly cold day, I tried not to use the furnace all that much, and just used blankets and jackets in its place. With these methods I saved a lot of money on my heating and air conditioning bills. I even called my parents and thanked them for letting me use the heating and air conditioning component so much at their place, I had no idea it cost nearly as much as it did.
