Overview of the DELLA 24000 BTU Mini Split AC
We’ve been putting this ductless inverter system through its paces, and we’re genuinely impressed by how much ground it covers – from sweltering summer afternoons to brutally cold winter nights. Rated at 22.5 SEER2 and 10 HSPF2, it sits comfortably among the most energy-efficient units in its class, carrying both Energy Star certification and AHRI listing to back that claim up. Whether you’re cooling a spacious bedroom, a home office, or an open-plan apartment up to 1,500 square feet, this system handles the load without breaking a sweat – or your electricity bill. What also caught our attention right away was the 2025 Red Dot Design Award recognition, which tells us the engineering team didn’t just focus on performance; they clearly cared about how the unit looks on your wall too. Installation was smoother than we expected, thanks to the all-inclusive kit that ships with a 16.4ft pre-flared copper line set and drain hose – no last-minute hardware store runs required.

| Minimum Operating Temp | -22°F |

Our Experience with Hyper Heat Performance and Energy Efficiency
Living in a region where winter temperatures can plunge well below freezing, we were specifically drawn to the Gold Fin technology and the system’s ability to deliver reliable heat output all the way down to -22°F. Most standard heat pumps tap out long before that threshold – this one doesn’t flinch. We ran it through a particularly harsh stretch of cold weather and found that warmth delivery remained consistent, never sluggish or spotty the way cheaper units tend to behave at low temperatures. On the energy front, the inverter compressor adjusts output based on real-time demand, which means we weren’t seeing those ugly spikes on our electricity usage. Over the course of a full billing cycle, the savings were noticeable enough to make us feel good about the investment. The Energy Star certification isn’t just a marketing badge here – it reflects actual, measurable efficiency that translates to lower monthly costs without sacrificing comfort at any point during the year.
What We Love About the Smart WiFi and Soft Airflow Features
Two features in particular have genuinely changed how we interact with our home climate: the smart connectivity and the soft airflow system. The Alexa integration and the Della+ app give us full control from anywhere – we’ve used it to pre-warm the house before getting home from work and even set schedules around our pets’ comfort when we’re away for the day. The “I Feel” sensor on the remote is a small but surprisingly impactful detail; it reads the temperature where you’re actually sitting rather than just at the unit, so the system responds to your real environment instead of a reading from across the room. As for the airflow design, we honestly didn’t realize how much a no-direct-draft system would matter until we experienced it. There’s no cold blast hitting you in the face, no constant urge to redirect the vents – air circulates evenly and naturally throughout the space. At just 32dB in Mute Mode, it’s so quiet we’ve genuinely forgotten it was running.
- Alexa & Della+ App – hands-free and remote scheduling made effortless
- “I Feel” Sensor – tracks temperature at the remote, not just at the unit
- Soft Indirect Airflow – no harsh drafts, ideal for sleeping and long-term use
- 32dB Mute Mode – whisper-quiet operation perfect for nurseries and light sleepers
- Pet & Schedule Comfort – automate temperature management around your lifestyle
Our Recommendations for Getting the Most Out of This Ductless System
After spending quality time with this unit across multiple seasons, we’ve picked up a few practical tips that make a real difference in performance and longevity. First, don’t skip the vacuuming step during installation – it’s required before operation and directly affects how efficiently the refrigerant circulates. Since the system comes pre-charged, proper setup is the only variable that’s truly in your hands. We also recommend taking full advantage of the scheduling features in the Della+ app; setting temperature windows around your daily routine means the system isn’t working harder than it needs to. Cleaning the filters every few weeks in high-use periods keeps airflow optimal and maintains that energy-efficient performance over time. And if you ever run into questions, the 24/7 live support team is genuinely helpful – we tested it and got a knowledgeable response quickly. Below is a quick reference for getting started on the right foot:
- Vacuum the line set before first use – don’t skip this step
- Use the scheduling feature to reduce unnecessary runtime
- Clean filters regularly – every 2-3 weeks during peak seasons
- Place the remote strategically to let the “I Feel” sensor work accurately
- Use Mute Mode at night for the quietest sleep-friendly experience
- Contact 24/7 live support for any setup questions – they’re responsive and helpful

✅ Pros
| Feature | Why We Love It |
|---|---|
| Soft, Indirect Airflow | No more harsh cold blasts hitting you directly. The air is distributed evenly, making it incredibly comfortable for sleeping, working, or extended daily use. |
| Whisper-Quiet at 32dB | In Mute Mode, this unit is so quiet you’ll genuinely forget it’s running. A total win for light sleepers, nurseries, and home offices. |

❌ Cons

| App Dependency for Smart Features | To get the most out of the WiFi and scheduling features, you’ll rely on the Della+ app. If the app experiences downtime or updates poorly, it can temporarily affect smart functionality. |

Q&A
Q&A: Your Questions About the DELLA 24000 BTU Smart Mini Split, Answered
We’ve rounded up the most common questions we’ve seen about this unit and answered them as clearly as possible so you can make the most informed decision before buying.
Q: What size space can the DELLA 24000 BTU mini split handle?
A: This unit is rated to cover spaces up to 1,500 square feet, making it a solid choice for large bedrooms, open-plan living areas, home offices, or studio apartments. We’d say it hits a sweet spot for spaces that are too big for a window unit but don’t necessarily need a full ducted system.
Q: How energy efficient is this mini split compared to others on the market?
A: Pretty impressive, honestly. It carries a 22.5 SEER2 rating for cooling and a 10 HSPF2 rating for heating, both of which put it well above the minimum efficiency standards. On top of that, it’s Energy Star certified and AHRI listed, so you’re not just taking the manufacturer’s word for it – those numbers have been independently verified. Over time, we think the energy savings could make a noticeable difference on your monthly utility bill.
Q: Can this unit really heat in extremely cold temperatures?
A: Yes, and this is one of the features we find most impressive. Thanks to its Gold Fin technology and hyper heat capability, this system can operate efficiently in temperatures as low as -22°F. That’s a big deal if you live somewhere that experiences harsh winters. Most standard heat pumps start to lose efficiency well before it gets that cold, so this unit genuinely stands out for cold-climate performance.
Q: Will the airflow bother me while I’m sleeping or working at my desk?
A: That’s actually one of the design priorities DELLA built into this system. The soft, indirect airflow feature means air is distributed evenly throughout the room rather than blowing directly at you. We think this is a game-changer for anyone who has dealt with the uncomfortable blast of cold air that some mini splits or window units can produce. Whether you’re sleeping, working, or just relaxing, you shouldn’t feel like you’re sitting in front of a fan.
Q: How quiet is it during operation?
A: In Mute Mode, this unit operates at just 32 decibels – that’s roughly on par with a soft whisper or rustling leaves. We think it’s genuinely quiet enough to run in a nursery, a bedroom, or any space where noise is a concern. Even outside of Mute Mode, it’s designed to run without being intrusive.
Q: Can I control this mini split with my phone or smart home devices?
A: Absolutely. You can manage the system through the Della+ app or by using Alexa voice commands. That means you can adjust the temperature, set schedules, or pre-heat your home before you even walk through the door. We especially like the “I Feel” sensor feature, which reads the temperature at the location of the remote rather than just at the unit itself – so you’re getting climate control based on where you actually are in the room.
Q: What comes in the box? Do I need to buy additional installation materials?
A: DELLA does a good job of keeping things straightforward here. The unit comes with a complete installation kit that includes a 16.4-foot pre-flared copper line set (both 1/4″ and 5/8″ lines) and a drain hose. That should cover most standard installations without requiring an extra trip to the hardware store. We appreciate that kind of all-in-one approach – it takes some of the stress out of the setup process.
Q: Does the unit come pre-charged with refrigerant?
A: Yes, it arrives pre-charged, which simplifies the installation process. That said, you will still need to have the system vacuumed before use, and you’ll need a 30A fuse as part of the electrical setup. We’d recommend working with a licensed HVAC technician for the installation to make sure everything is done safely and correctly.
Q: What voltage does this unit require?
A: It runs on 230V, which is standard for mini split systems of this size. Make sure your electrical setup can accommodate that before purchasing, and confirm with a qualified electrician if you’re unsure about your home’s wiring.
Q: Is there any customer support available if we run into issues?
A: Yes – DELLA offers 24/7 live support, which we think is a genuinely reassuring feature. Knowing that help is available around the clock, especially during installation or in the middle of a hot or cold snap, gives us confidence in the brand’s commitment to its customers.
Q: Has this unit received any industry recognition?
A: It has, and we think it’s worth mentioning. The DELLA 24000 BTU mini split is a 2025 Red Dot Design Award winner, which recognizes excellence in both product design and functionality. It’s a nice nod to the fact that this unit doesn’t just perform well – it also looks good doing it.
Ignite Your Passion
All things considered, we think the DELLA 24000 BTU Smart Mini Split is a seriously impressive unit that checks a lot of boxes. Whether you’re dealing with brutal winters, sweltering summers, or simply looking for a quieter, smarter way to manage your home’s climate year-round, this system brings a lot to the table. The combination of 22.5 SEER2 efficiency, whisper-quiet 32dB operation, and hyper-heating performance down to -22°F makes it a standout choice for both comfort-focused and energy-conscious homeowners. Add in the smart WiFi and Alexa compatibility, the thoughtful soft airflow design, and the all-inclusive 16.4ft installation kit, and you’ve got a package that genuinely feels well thought out from start to finish.
We especially appreciate how DELLA didn’t cut corners on the details – from the “I Feel” sensor for precise climate control, to the Gold Fin technology that protects against corrosion, to the award-winning design that won a 2025 Red Dot Design Award. These aren’t just marketing buzzwords; they translate into a product that’s built to last and perform in real-world conditions. If you’re covering a space up to 1,500 sq. ft. and want a reliable, modern ductless system, we’d confidently put this one near the top of our recommendations list.
