Temprium 12,000 BTU Mini Split

In this temprium 12,000 btu mini split review, the verdict is that this 115V system is the most energy efficient ductless mini split in our 2026 guide of 10, and it ranks #5 overall. The Temprium 12,000 BTU unit runs at 22 SEER2, draws 780 watts and covers up to 750 sq. ft., which suits a bedroom, sunroom, garage or home office used for long hours. At $549.99 it costs more than the budget picks, yet it holds a 4.4 star average from 165 Amazon ratings and ranks #6 in Amazon's Split-System Air Conditioners category. Shoppers who care most about power draw and quiet nights get the clearest win here.

The headline figure is 22 SEER2, which shows up at the meter because this system draws just 780 watts, so long cooling sessions cost less to run than on standard units that constantly stop and start. For example, 12,000 BTU of cooling covers up to 750 sq. ft., while the heat pump side delivers 12,300 BTU for winter, so one unit handles both seasons. On top of that, the DC inverter compressor modulates instead of cycling hard, which steadies the room temperature. In practice, the indoor head drops to 23 dB, quieter than a whisper, and sleep mode lowers the fan further overnight. Seven modes, a washable filter, an anti bacterial filter and a 133F self-clean cycle keep upkeep light. Meanwhile, WiFi plus Alexa and Google Assistant control let you cool the room before you walk in.

Value is where this Temprium unit needs a fair look. By contrast with the cheaper picks in our guide, you pay about $50 more, and the reward is the lowest power draw in the top 10 plus a 1 ton capacity for a single room. The 1 year manufacturer warranty is the weakest part of the package, and 165 Amazon ratings is a thinner track record than the Senville or COSTWAY models carry, so buyers are trusting a shorter history. Even so, the 115V power and the included installation kit make it a straightforward retrofit for a bedroom, sunroom, garage or addition. Because the system is single zone and needs a new outdoor unit, a three room home should look at a multi zone setup instead. If low running costs and quiet nights matter most, this one earns its place.
