Overview of the DELLA Umbra Series 18000 BTU Mini Split System
When we first came across this mini split system, we were immediately impressed by the breadth of features packed into a single unit. Designed to cool and heat spaces up to 1,000 square feet, this system runs on 208-230V and carries both ETL Listing and AHRI Certification, giving us confidence in its reliability and safety. What really stands out is the DC Inverter technology, which delivers up to 30% power savings compared to conventional systems – a serious win for anyone looking to cut down on energy bills. The unit also uses R32 refrigerant, a more environmentally responsible choice compared to the older refrigerants many competitors still rely on. Here’s a quick look at the core specs:
| Specification | Details |
|---|---|
| Cooling Capacity | 18,000 BTU/h |
| SEER2 Rating | 19 SEER2 |

Beyond the numbers, this system impresses us with its smart functionality and comfort-focused design. The I Feel mode uses the remote control as a temperature sensor rather than relying on the indoor unit, which means the system reacts to exactly where you are in the room – a subtle but genuinely useful feature. The 4D airflow (up, down, left, and right) ensures even distribution throughout the space, while the ultra-quiet 47 dBa operation keeps things peaceful whether you’re sleeping or working. Additional smart features include:
- 24-hour programmable timer for scheduled comfort
- Sleep mode for overnight energy efficiency
- Eco energy saving mode to reduce power consumption
- Turbo function for rapid temperature adjustment
- Heating, cooling, and dry (dehumidifying) modes
- Multiple fan speeds for personalized airflow control
- Alexa compatibility for hands-free voice control
It’s worth noting that professional installation is required – this isn’t a DIY setup – but a full installation kit, 13ft copper lines, and a 78.7″ drain pipe are all included to make the process as smooth as possible. Check the Latest Price on Amazon
What We Love About the Energy Saving Features and Alexa Integration
One of the standout aspects of this unit is how thoughtfully its energy-saving features have been engineered. The DC Inverter technology alone delivers up to 30% power savings, which we found genuinely impressive for a system of this capacity. The 19 SEER2 efficiency rating combined with the Eco Energy Saving Mode means you’re not just cooling or heating a space – you’re doing it responsibly. What also caught our attention is the smart sensor technology that reads room temperature directly from the remote control rather than the indoor unit, allowing the system to fine-tune airflow and temperature for both personal comfort and reduced energy consumption. Add in the 24-hour programmable timer and sleep mode, and you have a system that’s actively working to lower your energy bills without sacrificing comfort.
| Energy Feature | Benefit |
|---|---|
| DC Inverter Technology | Up to 30% power savings |
| 19 SEER2 Rating | High-efficiency certified performance |
| Eco Energy Saving Mode | Automatically reduces energy draw |
| Smart Sensor (Remote-Based) | Precise temperature control, less waste |
| 24-Hour Timer | Run only when needed |
The Alexa integration takes the convenience factor to a whole new level. Being able to control the unit hands-free – whether you’re adjusting the temperature, switching between cooling, heating, or dry modes, or toggling the turbo function – makes everyday management effortless. We love that the 4D airflow system (up-down and left-right) can also be directed through voice commands, ensuring every corner of your space stays comfortable. It’s the kind of smart home compatibility that feels truly useful rather than just a marketing checkbox. Whether you’re already deep into your Alexa ecosystem or just getting started, this level of integration adds real, tangible value to your daily routine. Check It Out on Amazon
How the 19 SEER2 Rating and Heat Pump Performance Impressed Us
When we started testing this unit, the 19 SEER2 efficiency rating was one of the first things we wanted to put to the challenge. We’ve reviewed plenty of mini splits over the years, and a high SEER2 number doesn’t always translate to real-world savings – but this one genuinely delivered. Thanks to its DC Inverter technology, we noticed up to 30% power savings compared to non-inverter systems we’ve used in similar spaces. The heat pump functionality also held its own, operating effectively in outdoor temperatures as low as 19°F (-7°C), which is impressive for a system in this class. Add to that the use of R32 refrigerant – a more environmentally responsible choice than the older refrigerants competitors still rely on – and it’s clear this system was designed with both performance and sustainability in mind.
| Performance Spec | Rating / Value |
|---|---|
| SEER2 Efficiency Rating | 19 SEER2 |
| Estimated Power Savings | Up to 30% |
| Minimum Operating Temp | 19°F / -7°C |
| Refrigerant Type | R32 (Eco-Friendly) |
| Certifications | ETL Listed, AHRI Certified |
What really stood out to us beyond the raw numbers was how the heat pump handled both heating and cooling modes with consistent efficiency. The smart sensor technology reads room temperature directly from the remote control rather than the indoor unit – a small but meaningful design choice that results in far more accurate comfort control. During our testing period, the system maintained steady temperatures across the full coverage range without the energy spikes we typically see with older systems. Here’s a quick look at the features that directly impacted our comfort and efficiency experience:
- Eco Energy Saving Mode – automatically reduces power consumption during low-demand periods
- I Feel Mode – adjusts output based on the temperature sensed at the remote, not just the room
- Turbo Function – rapidly reaches your desired temperature without prolonged high-energy operation
- Sleep Mode – gradually adjusts temperature overnight to avoid overcooling or overheating
- Temperature Range – adjustable between 60-90°F to suit any comfort preference
Our Final Thoughts and Recommendations on the DELLA Umbra Series
After thoroughly evaluating this ductless mini split system, we’re genuinely impressed by the combination of smart technology, energy efficiency, and comfort-focused features it brings to the table. The 19 SEER2 rating paired with DC Inverter technology delivering up to 30% power savings makes it a standout option for homeowners looking to reduce their energy bills without sacrificing comfort. The Alexa compatibility adds a modern convenience layer that many competing units simply don’t offer at this price point. Here’s a quick breakdown of the key specs we think matter most:

A: We’re happy to report that this unit packs quite a punch when it comes to coverage! The DELLA Umbra 18000 BTU Mini Split is designed to cool and heat spaces of up to 1,000 square feet. That makes it a solid choice for larger rooms, open-plan living areas, studio apartments, or even small offices. Just keep in mind that factors like ceiling height, insulation quality, and local climate can all affect how efficiently the unit performs in your specific space.
Q: Does the DELLA Umbra work as both an air conditioner and a heater?
A: Yes, it does, and that’s one of the things we really appreciate about this unit! The DELLA Umbra features a built-in 1.5-ton heat pump, meaning it can both cool and heat your space. It’s capable of operating in environments as low as 19°F (-7°C), so it holds up reasonably well even in colder climates. It can also adjust temperatures anywhere between 60 and 90 degrees Fahrenheit, giving you a nice wide range of comfort settings throughout the year.

It’s a genuinely convenient feature, especially if you already have an Alexa-enabled device set up in your home.
Q: How energy-efficient is this mini split system?
A: We’re glad you asked, because this is one area where the DELLA Umbra really shines! The unit carries a 19 SEER2 rating, which places it firmly in the energy-efficient category. On top of that, its DC Inverter technology is designed to deliver up to 30% in power savings compared to non-inverter systems. It also comes equipped with an Eco Energy Saving Mode that helps further reduce electricity consumption. If keeping your energy bills in check is a priority for you, this unit is definitely worth considering.
Q: How loud is the DELLA Umbra when it’s running?
A: This is a question we get a lot, and we’re pleased to share some good news here. The DELLA Umbra operates at just 47 dBa, which puts it in the “ultra-silent” category. To give you a sense of scale, that’s roughly comparable to the background noise in a quiet library. So whether you’re sleeping, working from home, or just relaxing, this unit shouldn’t cause any unwanted disruptions. We found its noise level to be one of its most impressive qualities during our testing.
Q: What smart features does the DELLA Umbra come with?
A: We were genuinely impressed by the range of smart features packed into this unit. Here’s a quick rundown of what you get:
- 4D Airflow – Directs air both up-down and left-right for full-room coverage

It’s a well-rounded feature set that we think most users will find both practical and easy to use.
Q: What refrigerant does the DELLA Umbra use, and why does it matter?
A: The DELLA Umbra uses R32 refrigerant, which is a newer and more environmentally friendly option compared to the older refrigerants that many competing units still use. R32 has a lower global warming potential, which means it’s a better choice for those of us who are mindful of our environmental footprint. It also tends to deliver efficient performance in terms of heat transfer. If you ever need to add more refrigerant down the line, we’d recommend checking with your local supplier for R32 availability.
Q: Can I install the DELLA Umbra myself?
A: We want to be upfront about this one – the DELLA Umbra is not a DIY mini split system. Professional installation is required, and the manufacturer is very clear about this. The installation process involves line-set vacuuming, and if the line-set length needs to be adjusted, the freon levels will also need to be recalibrated. That said, the unit does come with a full installation kit, including 13 feet of copper line and a drain pipe measuring 78.7 inches, which helps make the job easier for your installer. We’d strongly recommend budgeting for professional installation costs when you’re pricing this unit out.
Q: What are the electrical requirements for this unit?
A: The DELLA Umbra requires a 208-230V electrical connection and has a maximum fuse size of 15A. It’s ETL Listed and AHRI Certified, so you can trust that it meets recognized safety and performance standards. We’d recommend consulting with a licensed electrician before installation to make sure your home’s electrical setup is compatible with the unit’s requirements.
