Coverage Area
When considering the purchase of our cooling or heating system, it’s essential to determine the appropriate BTU output based on the square footage of your space. Please refer to the following coverage chart for guidance:
- 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
Keep in mind that additional factors, such as insulation quality, ceiling height, and the presence of appliances, can influence performance. For personalized assistance in selecting the optimal solution for your needs, don’t hesitate to reach out to our experienced Sales Team.

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.
