| Install | Priced as the condenser plus two Livo Gen4 9k wall heads (line sets typically sold separately — budget another $150-300). Pro install: flares, vacuum, and a dedicated 230V circuit. Mind Gree's connected-capacity table; the 18k condenser is happiest with 15k-21k of attached heads, and each zone has its own line-length budget. | Priced as the complete 9k+9k dual-zone kit with line sets included. Pre-charged with R454B for up to 50 ft of total line — go past that and you need a certified tech to add charge. Flare connections and vacuum pull mean this is realistically a pro or very confident DIY job, and Senville's warranty requires professional installation. |
| Warranty | 5-year limited parts warranty as sold online; longer coverage requires a registered Gree installing dealer | 10-year compressor / 5-year parts, contingent on professional installation |
