Difference Between 120V and 240V SystemsUpdated 11 days ago

What is the Difference Between 110/120 (115V) and 208/240 (230V) Systems?

There is no real performance-difference between 115V and 230V versions of the same BTU capacity. It all comes down to what you have available or preference. We offer the 115V versions of 9000 and 12000 BTU single-zone wall mounts for those whose panels are limited in adding additional electrical breakers. 230V would generally run more electrically efficiently, but the electrical cost to run either is fairly even. If you have the option to install either, typically a 230V is a bit better as it offers an easier upgrade path and it permits you to use slimmer gauge wire which is a bit more cost effective.

Only single-zone wall mounted ductless mini splits of 9 or 12 kBTU come with a 115V option. Other models such as light-commercial systems (cassettes and ductable units) as well as multi-zone models will all require 230VAC service.
