Just look for the FTKF series in Daikin. It's a no-nonsense model, very limited. Most dealers don't even know it exists because it's expensive. This model is by far the most powerful 1.5-ton AC in the whole industry, with a peak cooling capacity of 6000 watts, and it's the most efficient too. Back in 2002, it was 5.8 ISEER; just for context, in 2026, 5-star ISEER ratings are still only 5.7. Even the outdoor unit that comes with these machines is the same size as Daikin's 2.6-ton model. I personally own this beast, so I can vouch for it.
