I am about to pull the trigger on a 24,000 btu mini split for my shop. I have it narrowed down to either a LG- 21.5 seer or a Daikin- 18 seer. They are within $100 of each other and the Daikin has a 10 year warranty compared to the LG's 7 year warranty. I was hoping to get some feedback on these to units. Should I go for a higher seer or the little bit longer warranty?
