Hi, I am considering some ductless Heat Pump AC units. THE Samsung AVQ09JA I was quoted on has a SEER rating of 20. The Panasonic CSE09EKK is rated at 17 and the Carrier 38MVQ009-1 is rated at 10. IS there a large real world difference in these units? Do any have the build quality of the Mitsubishi or Fujitsu that some forum members have said are "High Quality"
Opinions appreciated. I am being quoted on two seperate 9000 BTU systems rather than 1 split system, as the installer says it is preferable than running lines an extra 40 feet? IS this accurate? Pros and Cons to a double system vs split system welcome.
