Here's my "dilemma". I've been at my current studio apartment for 15 years without AC just using a window fan. However, due to me being on LTD, I'm currently at home all the time. Some days have been absolute crazy with the heat so I thought about getting an AC.
A non-efficient AC is about $150 CAD and an efficient (inverter) is about $400 CAD. I was leaning towards the more efficient kind due to it's ability to always be on, but I seem to can't really justify paying $400 on something I will only use for like 2 months.
