I was doing some reading on You Tube videos and a point was made about SEER ratings on these inexpensive 110v eBay mini splits.
The one I mentioned above has nothing about SEER on it's auction site and on one of the videos the author did a calculation and came up with approx. 13, which isn't that great. He also mentioned the condenser doesn't have the ability for variable speed - only runs what it's set for.
So I found another on eBay rated for 19 SEER for only $749.99:
9000 BTU Ductless Mini Split Air Conditioner and Heat Pump 19 SEER 110 VOLT
And another which is 20 SEER for $819.99:
12000 BTU Ductless AC Mini Split Air Conditioner and Heat Pump 20 SEER 110 VOLT
Now I'm thinking either of these would be a better choice.....
