Hi. Im looking for a new air conditioner. Im thinking of buying the Panasonic 1HP with inverter. But after salesman recommend me the Carrier 1HP, I started to become choosy..need help/advice please.

Salesman told me:
Panasonic got:
Pros:
-1st 8hours, save 25% energy saving.
-after 8 hours then got 50% energy saving.
Cons:
-the refrigerant elements, if we use finger and push it, it simply deformed
-the after sale service/warranty is outsourced to another contractor, which in other mean, need to pay some and well, u know, leceh a bit..

Carrier got:
Pros:
-cheaper a bit.
-25% energy saving.
-well, this brand established since I was a kid. And they really specialized in Air cond and they do air cond only.
-after sale service/warranty by themselves.
Cons:
He didnt say anything bout cons.

Is it? Are you using Carrier's? Or anyone here? Is it good?

So I guess I will buy the panasonic inverter type then. Can anyone/user elaborate the pros and cons of it?
