YES!!! We have a national 2.0 or 2.5hp wall unit, circa 20 years old, and STILL blows 16 degrees set on cold. Hasn't missed a beat! Gets helped out by the new daikin 2.5hp inverter on real hot days tho.
A friend of mine from high school got a 1k loan to pay off his bills a couple years back after high school, ended up spending it on grog. So it can happen.
Spotted a house in salisbury north, faily run down, with a sign out the front saying "first $10,000 gets my 2 bedroom house". So im seeing if i can get the cash today, its worth the resale!
