The price of electricity in my country (the UK) has gone stupid high right now. We don’t have AC in our homes normally in the country. But I bought a 2nd hand portable unit about 7 years ago when my first son was born cos I was afraid of him gettin too hot at night. I have a 2nd son now and we have had some record high temps last month and o could only afford yo keep this AC unit on for a like 2 to 3 hours at night time in just his room and only on the hottest days. Anymore than that and we woild struggle to pay the energy bill that follows.

It’s not maintenance cost that’s the issue. It’s energy cost.

If you haven’t tried it. Based on what you listed. I think you will also like Father Ted.
