Senville Mini Splits Compared: Which Model to Buy
For most rooms, buy the Senville LETO 12,000 BTU ($799.99 on Amazon): it cools about 450 to 550 sq ft and runs on a 120-volt circuit. Plan on an installer: Senville says a DIY install voids its warranty. To install one yourself, buy a true DIY kit instead.

Can you install a Senville yourself?
Not if you want the warranty. Senville's warranty page says "DIY installation will void your warranty coverage." It also says "Pressure testing and evacuation of line sets must be completed by a licensed HVAC professional." It lists 10 years on the compressor and 5 years on parts, though "coverage periods may vary by product series", and asks you to register to activate coverage.
Senville ships a standard line set, not pre-charged quick-connect lines, so plan on an HVAC installer. If you want to do it yourself, a true DIY kit has lines that come charged and click together: see the best DIY mini-splits.

SEER2 is the cooling efficiency rating: higher costs less to run. Heat kept at 5°F is how much of its rated heat a unit still makes on a 5°F day. Both are AHRI-certified figures for the exact outdoor and indoor pair each listing names. Room size is ENERGY STAR's chart for cooling. Prices read live on Amazon, November 11, 2026.
Senville also sells AURA units at 9,000, 18,000 and 24,000 BTU. AHRI certifies each of those outdoor units with several indoor units that rate differently, and the Amazon listings do not say which one ships, so we show no certified numbers for them.
