Specifications side by side

How to choose the right one

1. Match BTU to room size

   Select the cooling capacity based on your square footage. The OYLUS 12,000 BTU model covers areas up to 750 square feet. This makes it suitable for large single rooms or open living spaces. If you have a smaller bedroom or office, the 9,000 BTU unit is more appropriate. Choosing the correct BTU ensures efficient temperature control without overworking the compressor. Always measure your space accurately before deciding on the unit size.

2. Check the SEER2 rating

   The SEER2 rating indicates seasonal energy efficiency. Higher numbers mean lower electricity costs over time. The top pick offers a 19 SEER2 rating, which is excellent for year-round use. The budget option provides a 17 SEER2 rating, which is still efficient for standard needs. Compare these figures to estimate your annual energy consumption. A higher rating helps you save on utility bills, especially in extreme weather conditions.

3. Verify 115V circuit compatibility

   All listed models operate on standard 115V power. This allows installation in rooms with existing outlets without a dedicated 230V circuit. You can install these units in older homes or apartments where high-voltage wiring is not available. Check your local electrical panel to ensure the circuit can handle the load. This feature simplifies installation and reduces the need for expensive electrical upgrades by a licensed electrician.

4. Consider heating capacity for winter

   Look at the heating BTU if you live in a cold climate. The 12,000 BTU model provides 12,500 BTU of heating power. This capacity helps maintain warmth in larger rooms during winter. The 11,500 BTU unit is designed for sub-zero heating performance. Ensure the heating output matches your room's thermal loss. Adequate heating capacity prevents the system from struggling to maintain comfort during freezing temperatures.

5. Review physical dimensions

   Check the indoor unit dimensions before mounting. The 12,000 BTU model is 32.3 inches wide and 11.9 inches high. The 11,500 BTU version is slightly narrower at 30.7 inches wide. Measure your wall space to ensure the unit fits comfortably. Proper clearance is needed for airflow and maintenance access. Verify that the mounting bracket can support the weight, which ranges from 68 to 74 pounds for these models.
