I read one page today. That was quite enough 
よつばと！vol1, cha3, pp104 🍀

だからできるだけクーラーは使わないようにしてるの、でもすっごく暑い日はつけちゃうの
That’s why if at all possible I make an effort not to use the air conditioner, but, as for very hot days, I switch it on
クーラーはわるいか⁉︎ちきゅうのてきか⁉︎
Air conditioners are bad!? They’re the enemies of earth!?
うーん…そんなには…
Yeah… (but) that much… (I’m thinking Ena is expressing that Yotsuba is taking it a little far :p)
あれ？よつばちゃんちはクーラーないの？
Huh? Doesn’t your house have (an) air conditioner(s)?
な、ないよ⁉︎
N- no!?
だってとーちゃんはいいものなんだ‼︎クーラーなんかないよ！
Because dad is a good person!! We don’t have anything like an air conditioner!
(なんだ=のだ？ explanatory の?)
ふーん、そっかー
Huh, is that so
…ないとおもう…
…I don’t think (we have)…
(I don’t understand what と is doing here and my Google-fu is failing me. Maybe I should buy All About Particles? Or is there a better book, as it uses romaji and that’s kind of bleh…?)
あれ⁉︎よつばちゃん⁉︎
What!? Yotsuba!?
