Our Experience With the Gree 24000 BTU Multi21+ Dual-Zone Concealed Duct Mini Split Heat Pump
When we decided to upgrade our home’s HVAC system, we knew we wanted something that would blend seamlessly into our living space while delivering powerful, efficient performance. After extensive research, we settled on this dual-zone concealed duct mini split system, and we couldn’t be more satisfied with our decision. What immediately impressed us was how discreet the indoor units are – tucked neatly above our suspended ceiling, they’re completely invisible to guests, delivering conditioned air through standard ceiling grilles without disrupting our interior design. The G10 inverter-driven compressor truly lives up to its reputation, maintaining a consistent room temperature without the jarring on/off cycling we experienced with our old conventional system. Here’s a quick breakdown of what we found most noteworthy during our experience:
- Silent Operation: Remarkably quiet, even during peak heating and cooling cycles
- Dual-Zone Flexibility: Both zones operate independently with no distribution box required
- Eco-Friendly Refrigerant: R410A refrigerant keeps our environmental footprint lower
- Concealed Installation: Fits above suspended ceilings or within closet spaces for a clean look
- Impressive SEER Rating: SEER 21 efficiency translates into noticeable savings on our energy bills
| Feature | Specification | Our Rating |
|---|---|---|
| SEER Efficiency | 21 SEER | ⭐⭐⭐⭐⭐ |
| Noise Level | Ultra-quiet G10 Inverter | ⭐⭐⭐⭐⭐ |
| Warranty Coverage | 5 yrs parts / 7 yrs compressor | ⭐⭐⭐⭐⭐ |
| Installation Flexibility | Ceiling/Closet Concealed | ⭐⭐⭐⭐⭐ |
One thing we want to highlight for anyone considering this system is the warranty structure – five years on parts and an impressive seven years on the compressor gives us tremendous peace of mind. However, it’s crucial to note that installation must be completed by a state-licensed HVAC contractor to remain eligible for warranty coverage, so factor that professional installation cost into your budget from the start. We also appreciated that the system handles two full zones without requiring any additional distribution boxes, simplifying the overall installation process considerably. The 208/230V power requirement was straightforward for our electrician to accommodate, and once up and running, the system performed flawlessly through both our cooling and heating seasons. If you’re ready to experience the same level of comfort and efficiency we’ve enjoyed, don’t hesitate to make the move.

Our Top Recommendations for Getting the Most Out of This System
When it comes to maximizing the performance of this dual-zone concealed duct system, there are a few key steps we strongly recommend following. First and foremost, always hire a state-licensed HVAC contractor for installation – not only is this required to maintain your warranty coverage, but it ensures the system is set up correctly for peak efficiency. Beyond installation, here are our top tips for getting the best results:
- Choose the right placement for your indoor units – above suspended ceilings or within open closet spaces work best for optimal airflow through ducting and grilles.
- Use compatible line sets – make sure you have the required 1/4″ x 3/8″ line sets (x2) ready before installation day to avoid delays.
- Let the G10 inverter do its job – avoid manually overriding temperature settings too frequently, as the inverter technology is designed to maintain steady comfort on its own.
- Schedule regular maintenance – clean or inspect your ducting, grilles, and filters seasonally to preserve airflow efficiency and system longevity.
- Register your warranty promptly after installation to secure your 5-year parts coverage and 7-year compressor protection.
To help you plan your setup more effectively, we’ve put together a quick reference table comparing the two zones this system supports, so you can allocate BTU capacity and coverage area thoughtfully:
| Zone | Indoor Unit BTU | Ideal Room Size | Recommended Placement |
|---|---|---|---|
| Zone 1 | 9,000 BTU | Up to 400 sq ft | Master bedroom or living area |
| Zone 2 | 9,000 BTU | Up to 400 sq ft | Guest room or home office |
By following these recommendations, you’ll be getting the absolute most out of your investment in year-round, whisper-quiet comfort. Ready to bring this system home? Check the Latest Price on Amazon

Q&A
Q&A Section
Q: What does the “dual-zone” feature mean in the Gree Multi21+ Mini Split?
A: Great question! The dual-zone feature means that this system can heat and cool two separate areas or rooms independently, all from a single outdoor unit. What we love about this is that it gives you complete control over the comfort level in each zone without needing distribution boxes, making the whole setup simpler and more efficient.
Q: How energy-efficient is the Gree Multi21+ Mini Split?
A: We’re happy to report that this unit is quite impressive in the energy efficiency department! It carries a SEER rating of 21, which is considered excellent. This is largely thanks to Gree’s G10 inverter technology, which avoids the harsh starts and stops of conventional systems. The result is a steadier room temperature and lower energy consumption overall.
Q: What makes the concealed duct design special?
A: We think this is one of the standout features of this system! The slim indoor units are specifically designed to be hidden above suspended ceilings or within open closet spaces. They deliver conditioned air through ducting and ceiling or wall grilles, keeping your living space looking clean and uncluttered. It’s truly the perfect solution for those of us who value both comfort and aesthetics.
Q: Does this unit work as both an air conditioner and a heater?
A: Absolutely! The Gree Multi21+ is a heat pump system, which means it functions as both an air conditioner and a heater. Whether you’re trying to cool things down during a hot summer or warm up on a chilly winter night, this unit has you covered in both zones simultaneously.
Q: How loud is the Gree Multi21+ when it’s running?
A: One of the things we appreciate most about this system is how quietly it operates. Thanks to Gree’s G10 inverter technology, the outdoor unit runs at reduced noise levels compared to traditional HVAC systems. The elimination of constant on/off cycling means you get a much quieter and more consistent performance throughout the day.
Q: What kind of refrigerant does this system use?
A: The Gree Multi21+ uses R410A refrigerant, which is an eco-friendly option compared to older refrigerants. It’s widely used in modern HVAC systems and is known for its efficiency and lower environmental impact, which is something we think most homeowners will appreciate.
Q: What voltage does the Gree Multi21+ require?
A: This unit operates on 208/230V, which is standard for most residential HVAC installations. We recommend confirming that your home’s electrical setup is compatible before purchasing, or consulting with a licensed HVAC contractor who can assess your specific needs.
Q: Does this system come with a warranty?
A: Yes, it does! Gree offers a solid warranty package with this unit – 5 years on parts and an impressive 7 years on the compressor. However, we want to make sure you’re aware of an important condition: in order to be eligible for the warranty, installation must be performed by a state-licensed HVAC contractor. So please keep that in mind when planning your installation!
Q: What additional components will I need to purchase for installation?
A: While the system itself includes everything you need to get started, you will need to purchase line sets separately. Specifically, you’ll need two 1/4″ x 3/8″ line sets, which are not included with the unit. We always suggest consulting with your licensed HVAC contractor ahead of time so they can help you determine the exact lengths and any other materials you might need for a smooth installation.
Q: Is professional installation really necessary for this unit?
A: We strongly recommend it – and not just for safety reasons! As we mentioned above, professional installation by a state-licensed HVAC contractor is a requirement for the warranty to be valid. Beyond that, a qualified technician will ensure that the system is set up correctly and running at peak efficiency, which will save you time, money, and headaches in the long run.
