What is a MRCOOL Cassette and How is it Used?
A MRCOOL Ceiling Cassette is a ductless mini-split air handler designed to mount flush within your ceiling, offering both cooling and heating. It is particularly well-suited for spaces where traditional wall-mounted units may not be ideal or where aesthetics demand a more discreet solution. Everyday use is straightforward:

- Remote Control & Smart Integration: Adjust temperature, mode (cooling/heating), and fan speed easily using the included remote, smartphone app, or voice commands through smart assistants.
- Easy Maintenance: The filter panel can be lowered remotely for effortless cleaning, reducing the need for ladders or professional maintenance calls.
- Year-Round Use: Designed for both summer cooling and winter heating—simply select the required mode on your controller.

How to Choose the Right MRCOOL Cassette Ceiling Unit
Step 1: Assess Your Space Size and Needs
- Room Size: Use BTU calculators or the estimates below to find the right fit:
- 9K BTU: Up to 350 square feet
- 12K BTU: 350–550 square feet
- 18K BTU: 550–750 square feet
Step 2: Decide Single vs. Multi-Zone
- Single-Zone (18K only): Perfect for conditioning one large space.
- Multi-Zone: Combine cassettes with wall units for customizable, whole-home or multi-room climate control. Required if mixing and matching air handlers in different rooms (multi-zone condenser needed).
Step 3: Compatibility
- 4th & 5th Generation Condensers: Ensure your cassette matches your MRCOOL DIY system’s generation (most cassettes are compatible with 4th and 5th gen).
- Electrical Requirements: Verify power requirements, typically 230V.
Step 4: Installation Considerations
- Ceiling Joists: Unit fits between 16″ center joists (including I-joists); ensure adequate space.
- Line Set: Use the pre-charged No-Vac Quick-Connect Line Set for the easiest install.
- DIY or Pro Install: Most homeowners with basic tools can perform the install. If you’re not comfortable with electrical work, hiring a pro is advised.
Step 5: Smart Features
- Wi-Fi/Bluetooth Readiness: If you want app-control, make sure a Wi-Fi dongle is included; Bluetooth can also work if in direct range.
- Future Expandability: Planning a whole-home system? Multi-zone compatible condensers are key.
User Tips & Best Practices
- Placement Matters: Choose a central ceiling location free from obstructions for optimum air distribution.
- Routine Cleaning: Use the remote Elevation function every 1–2 months to lower the filter and clean dust buildup. This keeps air quality high and the unit efficient.

- Smart Schedules: Set up daily/weekly climate schedules through the MRCOOL app to save energy.
- Register Your Warranty: Complete warranty registration after install for lifetime/longevity benefits.
