Our top pick: Rellytech 12,000 BTU 115V Mini Split.
How these six alternatives compare
YITAHOME 12000 BTU 115V Mini Split
The YITAHOME unit matches the 115V requirement and offers 12,000 BTU cooling, but it improves efficiency with a 20 SEER2 rating compared to the Rellytech’s 19 SEER2. It adds Wi-Fi smart control, which the Rellytech lacks. You gain app management for scheduling and remote adjustments. However, it is heavier at 22 pounds versus 92 pounds for the Rellytech, though dimensions differ significantly. The YITAHOME is taller and narrower. Choose this if you prioritize higher energy efficiency and smart connectivity over the Rellytech’s certified quiet operation and lower weight.
COSTWAY 12000 BTU 115V Mini Split
The COSTWAY 12000 BTU model shares the 115V circuit and 12,000 BTU capacity but lists a 20 SEER efficiency rating, beating the Rellytech’s 19 SEER2. It lacks Wi-Fi smart control, aligning with the Rellytech’s manual approach. The unit is significantly lighter at 68 pounds compared to 92 pounds. Its width is much larger at 44.5 inches, requiring more wall space. The height is also greater at 13 inches. Pick this alternative if you want higher efficiency and a lighter unit, provided you have the wall space for its wider footprint.
Senville LETO 9000 BTU 115V
The Senville LETO reduces capacity to 9,000 BTU, making it suitable only for smaller rooms than the Rellytech’s 12,000 BTU coverage. It runs on 115V and includes smart heat pump control via app, a feature the Rellytech does not offer. It is much lighter at 25 pounds. The dimensions are wider at 37 inches and taller at 12 inches. This model sacrifices raw cooling power for smart management and compact weight. Select it for small spaces where app control is essential and lower BTU output is acceptable.
ROVSUN 9000 BTU 20 SEER2 Mini Split
The ROVSUN unit provides 9,000 BTU cooling on 115V, which is less than the Rellytech’s 12,000 BTU. It offers a higher 20 SEER2 efficiency rating and includes Wi-Fi smart control, unlike the Rellytech. It weighs 70 pounds, which is lighter than the Rellytech’s 92 pounds. The dimensions are similar in width but slightly taller. This model trades cooling capacity for better energy efficiency and smart features. Choose it for smaller rooms where you need app control and higher efficiency ratings without the bulk of the Rellytech.
COSTWAY Blast Pro 12000 BTU
The COSTWAY Blast Pro delivers 12,000 BTU cooling on 115V, matching the Rellytech’s capacity. It offers a 20 SEER2 efficiency rating, surpassing the Rellytech’s 19 SEER2. It includes Wi-Fi smart control, adding app management capabilities. The unit is significantly lighter at 19.8 pounds compared to 92 pounds. It is narrower in depth but slightly taller at 12.1 inches. This model provides better efficiency and smart features with much less weight. Pick it if you want the same cooling power with enhanced efficiency and remote control access.

Frequently asked questions
Which alternative offers the best energy efficiency?
The YITAHOME and COSTWAY Blast Pro models both achieve a 20 SEER2 rating, making them the most efficient options on this list. This high rating means lower electricity usage for the same cooling output. The Rellytech model follows closely with a 19 SEER2 rating. You should choose the 20 SEER2 units if minimizing energy consumption is your primary goal.
Do these units require a special electrical outlet?
No, all six alternatives listed here operate on standard 115V circuits. This means you can likely use your existing standard household outlets without installing new heavy-duty wiring. The Rellytech, YITAHOME, COSTWAY, Senville, and ROVSUN models all specify 115V compatibility. This makes installation easier and more accessible for most homes.
