Why on earth could an AC unit not run backwards? You just reverse the
pump. Every one I've seen in the UK (commercial and home) has been able
to do this. The controller usually has settings for heating, cooling,
or automatic. On automatic you can simply set a range (say 18 - 22C)
and if it goes over, it cools, if it goes under, it heats.


For most of us, no need. We only use cooling here for two months. We
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 yourself.
I for one, won't educate you. All you do is turn your troll questions into
a 300 post thread of BS.

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