Della Optima TP Series Mini-Split AC Review: Affordable Smart Cooling with Some Quirks

Ductless mini-split air-conditioners now hold over 40% of the domestic market, with even higher adoption in Asia and Europe. Della's Optima 048-TP-12K1V-23S-IN offers 12,000 BTU cooling and 12,400 BTU heating, covering 550 sq ft, priced at $921 on Amazon. Professional installation in Austin cost $3,600. The unit features a remote control and a Della+ mobile app with scheduling, Alexa/Google Assistant support, and geofencing—though geofencing never worked after 10 days of troubleshooting. The remote has 15 buttons and an infrared sensor; the app is more intuitive. Noise levels range from 40 dB (night mode) to 50 dB (turbo). Della offers a lifetime warranty for professionally installed units, requiring extensive documentation. Despite geofencing issues, the unit reliably heats and cools.
