Are dual-hose portable ACs worth the extra cost?

Yes. The 30-40% efficiency improvement means lower electric bills, faster cooling, and less runtime. The extra $50-100 upfront pays for itself within one summer of heavy use.

Can I convert a single-hose AC to dual hose?

No. The internal airflow design is fundamentally different. Single-hose units pull condenser air from the room; dual-hose units are plumbed to pull it from outside.
