MRCOOL DIY Mini Split Sizing Guide
When choosing a ductless mini split heat pump, it's important to pick the right size for your space.
Here’s a friendly guide to help you size your MRCOOL DIY 4th Gen unit:
Consider the Square Footage
The size of your room is the main factor in choosing the right unit. MRCOOL DIY 4th Gen comes in various sizes, each designed to cool and heat specific square footage ranges.
Understanding BTU
BTU, or British Thermal Unit, measures the cooling capacity of an air conditioner or heat pump. A higher BTU means more cooling power, which is key for larger spaces. MRCOOL DIY 4th Gen units come in different BTU sizes to suit various room sizes.
Here's a quick reference for choosing the right BTU based on your room size:
- 9,000 BTU covers up to 375 square feet.
- 12,000 BTU covers up to 550 square feet.
- 18,000 BTU covers up to 800 square feet.
- 24,000 BTU covers up to 1,050 square feet.
- 36,000 BTU covers up to 1,550 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 4th Gen unit is perfectly sized for your needs, keeping you comfortable year-round.
