Always calculate the BTU of your air handler (AH) based on the square footage of each zone where you intend to install one.

9,000 BTU (AH) covers 375 square feet.
12,000 BTU (AH) covers 550 square feet.
18,000 BTU( AH) covers 800 square feet.
24,000 BTU (AH) covers 1,050 square feet.
36,000 BTU (AH) covers 1,550 square feet.

Understand Your Mini-Splits System: Here's How BTU Limits Work.

You can choose high BTU air handlers for powerful heating and cooling. However, if you plan to run multiple air handlers at the same time, you need to consider the main unit's (condenser) maximum power.

Here's how it works: Let's say the condenser can handle 18,000 BTU, and you have two indoor air handlers, each at 12,000 BTU. If you run them both simultaneously, they'll automatically drop down to 9,000 BTU each. They do this to match the condenser's 18,000 BTU limit, ensuring everything runs safely.

If you plan to run only one air handler at a time, a lower BTU condenser might be fine. But if you plan to run all of the air handlers together, you might want to opt for a higher BTU condenser. This way, you can enjoy the full power of each air handler without overloading the system.

Heating Performance: The DIY mini-split can heat at 100% capacity at – 5 degrees Fahrenheit, even with outdoor temperatures as low as -13 degrees Fahrenheit.

Cooling Performance: The DIY mini-split can cool at 100% capacity with outdoor temperatures as high as 122 degrees Fahrenheit.

Dry Mode: The operating range is from 32°F to 122°F.

Note: If the air conditioner runs for an extended time in cooling mode in high humidity (above 80%), water droplets may form and drip from the unit. To prevent this, adjust the vertical airflow louver to its maximum angle (pointing downwards) and switch to high fan mode.

All DIY® 4th gen systems have a *LIMITED LIFETIME compressor warranty, 7-year replacement, and 5-year parts warranty for the original owner.

To qualify for the limited lifetime warranty, purchase the mrcool cleaning kit ($117) twice a year, clean your mini-splits and register it on the official MRCOOL website once the cleaning is done.
