Split/Ductless A/C Experts?

[JHZR2]

Hi,

Considering putting in a split ductless system in my home. Would like to set up a single outdoor condenser which can feed multiple zones.

Thus my questions:

- if I run a big condenser with multiple zone connectivity, but run only one zone at low levels, is this an issue? For example, if I have a 30k+ btu condenser but are only running one zone at 5000BTU, could this be an issue?

- if I get a multi-zone system, but don't connect up all zones, could this be an issue?

- how do split ductless systems deal with condensation? I assume that each air handler has it's own gravity drain out of the home and down to the ground? The benefit of split is the fact that there is just two pipes and a wire or two... So I assume that there is just another tube?

- are there known issues or considerations with these high efficiency inverter type >20SEER systems?

Thanks!!!

I'm sure not an expert, but according to Friedrich's website they use both a variable-frequency-drive compressor and condenser fan to adapt to the loading of the indoor units. Should be no problem with the zones being used differently. FWIW, Friedrich would be my brand of choice when it comes to one of these systems. The place I work uses them as server room backup/auxiliary cooling systems and have had no issues.

Freidrich would be my choice because of US manufacture...

Though I'd consider Mitsubishi if the seer is far higher.

Yes, I put ductless units in my last office and each evaporator unit has to have it's own condensate drain line.

I think these ductless units are the way to go for efficiency and cost savings on ductwork, but try to hear the units you're looking at before you buy. The ones I got ( can't remember brand ) are noisy.

Inteesting. Most of the air handlers are in the 50 dB range, and the old Mr Slim (Mitsubishi) that we regularly use at one place are far quieter than our best window unit at home.

Do you mean outdoor units?
