How the Alternatives Compare
Rellytech 17000 BTU 230V Mini Split
The Rellytech 17000 BTU model shares the same 230V voltage and 17 SEER2 efficiency rating as the OYLUS, but it is slightly more compact. Its indoor unit measures 31.9 inches wide and 9.5 inches high, compared to the OYLUS 35.8 by 11.6 inches. This smaller footprint may suit tighter wall spaces. Both units offer 4D auto-swing airflow. The Rellytech does not list a heated base pan or cold-weather heating specs in the provided data. You should choose this if you need a slimmer indoor unit for a 230V installation but do not require the specific cold-climate heating features of the OYLUS. It is a solid alternative for medium rooms where space is limited.
COSTWAY 9000 BTU Mini Split
The COSTWAY 9000 BTU Mini Split is significantly smaller and lighter than the OYLUS. It weighs only 24.4 pounds versus the OYLUS 78.1 pounds. Its cooling capacity is 9000 BTU, which is half the OYLUS 17000 BTU. It still uses 230V power and offers a 17 SEER2 efficiency rating. The indoor unit is 31.2 inches wide, making it narrower than the OYLUS. This model is best for small rooms with low cooling demands. It is not suitable for large spaces like living rooms or home offices that the OYLUS can handle. If you only need to cool a small bedroom or office, this lighter, less powerful unit is a practical and efficient choice.
Mountman 18000 BTU 19 SEER2 Mini Split
The Mountman 18000 BTU Mini Split offers higher cooling capacity and better efficiency than the OYLUS. It provides 18000 BTU of cooling and holds a 19 SEER2 rating, which is two points higher than the OYLUS 17 SEER2. It also runs on 230V power and covers up to 1,250 square feet. The indoor unit is larger, measuring 40.4 inches wide and 12.6 inches high. This makes it a bulkier installation. You should pick this if you need maximum efficiency and extra cooling power for a larger room. It is ideal for homes with 208/230V wiring that prioritize energy savings and quiet operation over the compact size of the OYLUS.
YITAHOME 12000 BTU 230V Mini Split
The YITAHOME 12000 BTU Mini Split is designed for smaller spaces under 750 square feet. It has 12000 BTU of cooling capacity, which is less than the OYLUS 17000 BTU. It shares the 230V voltage and 17 SEER2 efficiency rating. A key difference is its smart control feature, which includes Wi-Fi connectivity. The OYLUS data does not mention Wi-Fi. The YITAHOME unit is also lighter at 21.1 pounds. This makes it easier to install in tight spots. Choose this model if you want smart home integration and quiet performance for a small room. It is not a direct replacement for large spaces due to its lower cooling output.
Nexaro 12000 BTU 230V Mini Split
The Nexaro 12000 BTU Mini Split is a wall-mounted unit with 230V power and a 17 SEER2 efficiency rating. It covers up to 750 square feet, which is half the area of the OYLUS. Its indoor unit is 31.5 inches wide and 11.4 inches high, making it narrower than the OYLUS. The Nexaro weighs 68 pounds, which is lighter than the OYLUS 78.1 pounds.
