What pushes it up

  • West-facing glass
  • High ceilings
  • Poor insulation
  • Top floor
  • Western Sydney summers

What pushes it down

  • South-facing
  • Good insulation
  • Ground floor

Bigger is not better

Too big is a problem too

It short-cycles, doesn't dehumidify, costs more.

“recommended a great little unit for me - didn't try to up sell me to something I didn't need. I had asked him for his honest option and was willing to stretch the budget. He was also very quick. My husband and I were impressed.”
