A regular mini split will have better zone control because you have air flow control to every zone.

How hot the air should coming out of the register ?

No emergency drain pan . No emergency float switch . Hope the drain doesn't stop up. Homeowner has a good lawsuit .

Well that drain line looks like it's going to sweat real well

Nothing new , been around for a couple decades.

Do you think a 2 ton mini split unit will be sufficient enough for a 700 square foot room if the condenser is located 50 to 60 ft away from the evaporator?

Ducted is the way to go, however we find many HVAC companies doing mini split wall units are may not know how or have access to designing, fabricating, sealing, testing sheet metal ducting for these units. The smaller Slim Duct blowers only produce .36 inches of water static pressure where as a standard blower will product from .5 to some at 1.O in of static. For example a.36 static sees the filter first, or .15 static resistance. This leaves 2.1 for the furtherest supply and return wit their registers included.

Low static does not mean a short duct system if it is well designed. We have installed these blowers with ducting running 3 stories with many feet of duct. For example a 9000 btu 3/4 ton blower needs 300 cfm and might require a 8×14 inch duct to run 3 stories decreasing in size as air is supplied to each area. All 90's will need to be long radius or include turning vanes. With a traditional unit with a high static blower 300 cfm might require an 8×8 inch duct and be able to used standard fittings sold in any supply house. Generally ducted mini splits ducting should be sized to allow for the lowest speed on the blower to convey the amount of air needed to run the unit at it's lowest capacity. if one sizes the duct system for the highest static the unit can overcome it will not have sufficient air flow at the lowest speed air speed and capacity. In a nutshell the unit would only be able to run efficiently at the highest fan speed. 

Mini split heat pumps can be installed using medium static blowers and high static blowers but both of these choices will require some form of back up heating in below freezing applications, where the pictured blower will not. Additionally the a Slim Duct blower is very compact in size were a medium static is much larger and high static sized the same as a typical blower or slightly larger.

Do you have a system tour video? I JUST got my CH ducted system delivered and I'm so intimidated by the duct work portion. I got a 1/2 ton system for 1500sf

These things suck especially in tight spaces when you eventually have to replace them.

@josephdestaubin7426 says:

Isn't a ducted "mini split system" just a small split system?

@jmaegm says:

Originally mini split are ductless. If you want duct then just get central air
