Coverage Area
When selecting an air conditioning or heating unit, it’s crucial to match the appropriate BTU (British Thermal Unit) output with the square footage of your space. To simplify this process, consult our coverage chart below:
- Square Feet: 180-375 | BTU = 9K
- Square Feet: 376-500 | BTU = 12K
- Square Feet: 501-750 | BTU = 18K
- Square Feet: 751-1,000 | BTU = 24K
- Square Feet: 1,001-1,500 | BTU = 36K
These values represent the recommended BTU ratings for various room sizes. However, it’s important to consider additional factors such as insulation, ceiling height, and the presence of appliances, as they can affect performance.

Handling Line Sets
When installing your MRCOOL system, handle refrigerant lines carefully to ensure optimal performance and prevent damage.
Bending the Copper Lines: Maintain a minimum 4-inch bend radius and use smooth curves instead of sharp angles to protect the lines and ensure proper refrigerant flow.
Avoid Repeated Bending: Bending copper lines more than three times can harden and weaken them, increasing the risk of breakage. Handle with care and minimize adjustments.
For best results, use gradual bends and consult a licensed professional or our support team if needed.
