Why on earth could an AC unit not run backwards?* You just reverse

For most of us, no need.* We* only use cooling here for two

have very efficient central heat and the AC goes into a window in
the
summer for cooling only. It can also get very cold here.

In more mild areas, central AC with heat pump is common and works
well.

If you only cool for 2 months, I assume you heat for more than that.
Why wouldn't you want a heat pump for that?* Why wouldn't you want
them both to be the same unit?

You know so damn much, why are you asking us?** Go figure it out

I for one, won't educate you.* All you do is turn your troll questions

I've pointed out a superior system and asked why you're using the old
one.* I'm waiting for an answer.


Since you are incapable of thinking yourself, it comes down to one

I looked into buying one in the UK.* The cheapest one runs both ways.


Surem but it would be 40% cheaper if it only cooled. You guys get hosed.
