idylis is the brand they say they are 14k btu but its more like a solid 10k
they work great these last 3 summers have been brutal, with one year having 100 days over 100 degrees, at night time when the sun goes down the temps only drop to 90 degrees.
most people in Texas run their light at night because its too hot in the day, in the middle of summer time on the hottest day i can have my room at 65 if i want it.
and i get the 2 duct ac units because they pull outside air to cool off the condenser where as the single ducting ones are pulling air from inside the room and run it into the attic, and no booster fans are needed the built in fans on it are powerful enough. the only down side it all the holes i cut into the ceiling of these houses, but once you figure out how to patch the holes its a breeze, still nerve wrecking on your first house to just start cutting holes in walls and ceilings and running wires
i got a couple of before and after pics i took of some rooms ill post up
