Which air handler is best for your room size?
The size of your room is the main factor in choosing the right unit. MRCOOL DIY 5th Gen comes in various sizes, each designed to cool and heat specific square footage ranges.
Here's a quick reference for choosing the right BTU based on your room size:
- 6,000 BTU covers rooms under 150 square feet (multi-zone only).
- 9,000 BTU covers 150 to 350 square feet.
- 12,000 BTU covers 351 to 500 square feet.
- 18,000 BTU covers 501 to 750 square feet.
- 24,000 BTU covers 751 to 1,000 square feet.
- 36,000 BTU covers 1,001 to 1,500 square feet.
How BTU Limits Work in Your Mini-Split System
You can opt for high BTU air handlers for strong heating and cooling. But, if you plan to run multiple air handlers at the same time, consider the main unit's (condenser) maximum power.
Here’s the deal: Suppose your condenser can handle 18,000 BTU, and you have two indoor air handlers, each at 12,000 BTU. If both run simultaneously, they’ll automatically adjust to 9,000 BTU each to match the condenser's limit. This ensures the system runs safely.
If you usually run one air handler at a time, a lower BTU condenser might be sufficient. But if you plan to use all air handlers together, a higher BTU condenser is the way to go. This lets you enjoy the full power of each air handler without overloading the system.
By considering these factors, you can ensure your MRCOOL DIY 5th Gen unit is perfectly sized for your needs, keeping you comfortable year-round.
