@infryq @CelloMomOnCars Are traditional window AC units effectively providing heat for…anyone? No, they’re not designed for that, in many ways.
Do machines actually designed for that purpose work? Yes, very well.
Are the modern compressors sold as “heat pumps” also more efficient? Yes.
Is the article’s headline claim correct? Yes.
Can people make their own cost tradeoff decisions about this? Yes.
Come on.
