When it comes to keeping our home comfortable year-round without breaking the bank on energy bills, we are always on the lookout for solutions that are both powerful and smart. That is exactly what led us to put the DELLA Serena 22 SEER2 18000 BTU Smart Wifi Mini Split Heat Pump to the test, and we have to say, we were genuinely impressed by what this system brings to the table. Whether you are trying to cool down a sweltering living room in the middle of summer or warm up a chilly bedroom when temperatures drop as low as 5°F, this 1.5-ton ductless unit promises to handle it all with remarkable efficiency. With its industry-leading 22 SEER2 energy rating, Alexa and Google Home compatibility, Energy Star certification, and DELLA’s very own PureClean technology, this mini split system is clearly designed with both comfort and innovation in mind. We spent quality time living with this unit installed in our space, testing everything from its whisper-quiet 22 dBa mute mode to its geo-location smart features, and we are here to share every detail of our experience with you. So, if you are considering upgrading your home’s climate control for a room of up to 1,000 square feet, keep reading – this review has everything you need to know.
Our First Impressions of the DELLA Serena 22 SEER2 Mini Split Heat Pump
When we first got our hands on this unit, we were immediately struck by how well-thought-out the overall package is. Unboxing revealed a clean, modern design – no surprise given that DELLA took home the 2025 Red Dot Design Award. The included 16.4ft installation kit with standard copper pipes and a 78.7″ drain pipe felt solid and complete, though we want to be upfront: professional installation is required, so factor that into your planning. Once installed and powered up on 230V, the system came to life quietly – and we mean genuinely quietly, running at just 22 dBa in mute mode. That alone impressed us more than we expected.
| First Impression Factor | Our Take |
|---|---|
| Noise Level | Whisper-quiet at 22 dBa 🔇 |
| Design Quality | Sleek, award-winning build |
| Installation Kit | Comprehensive, well-packaged |
| Smart Setup | Alexa & Google Home ready out of the box |
| Energy Efficiency | 22 SEER2 – top-tier rating |
From a features standpoint, our first impressions were equally positive. The unit is loaded with practical functionality right from the start, and we appreciated how accessible the smart controls felt – pairing with the DELLA app, Alexa, and Google Home was straightforward. The geo-location feature stood out as a genuinely clever touch, automatically adjusting the temperature based on whether you’re home or away. On top of that, knowing the system is Energy Star certified, operates on inverter technology for up to 57% energy savings, and is backed by a lifetime warranty with 24/7 live chat support made us feel confident we were looking at a serious, well-supported product. Here’s a quick snapshot of what caught our eye most:
- PureClean Technology – actively prevents dust buildup and keeps indoor air fresher
- 4D Airflow – covers up-down and left-right directions for full room coverage
- Cold-weather reliability – outdoor unit performs dependably down to 5°F / -15°C
- Multiple operating modes – including Turbo, Eco, Sleep, Dry, and I Feel mode
- Coverage – handles rooms up to 1,000 sq. ft. with ease
What We Love About the Smart WiFi and Alexa Integration
One of the standout features we genuinely appreciate is how effortlessly this unit connects to your smart home ecosystem. Through the DELLA app, Amazon Alexa, and Google Home, you can control your heating and cooling from absolutely anywhere – no need to be in the same room, or even the same city. What really sets it apart, though, is the exclusive geo-location function, which automatically adjusts the temperature based on where you are. It saves energy while you’re out and ensures your space is perfectly comfortable the moment you walk through the door. No more coming home to a sweltering room or wasting energy cooling an empty house.
| Smart Feature | What It Does | Benefit |
|---|---|---|
| Alexa & Google Home | Voice control integration | Hands-free convenience |
| DELLA App (WiFi) | Remote control from anywhere | Full control on the go |
| Geo-Location Function | Adjusts temp based on your location | Energy savings + comfort on arrival |
| Physical Remote Control | Traditional handheld remote included | Always a backup option |
Beyond the voice commands and app control, we love that a physical remote control is also included – so every household member, regardless of their comfort with smart tech, can easily operate the system. The combination of smart WiFi connectivity, geo-location intelligence, and multiple control options makes day-to-day use feel remarkably intuitive. Whether you prefer asking Alexa to cool things down or adjusting settings from your phone while commuting home, this unit adapts to your lifestyle rather than forcing you to adapt to it. It’s the kind of thoughtful smart integration that actually makes a difference in everyday comfort and energy efficiency.
- Voice control via Alexa and Google Home for effortless adjustments
- DELLA app lets you monitor and control your climate remotely
- Geo-location feature intelligently optimizes comfort and reduces energy waste
- Included remote control ensures easy access for everyone at home

How the 22 SEER2 Energy Star Rating Saves Us Money on Our Bills
One of the biggest reasons we chose this unit was its 22 SEER2 rating, and after a few months of use, we can honestly say it has made a noticeable difference on our energy bills. The inverter technology is the real hero here – instead of constantly switching the compressor on and off like older systems, it adjusts the power supply frequency to maintain the desired temperature with minimal energy waste. According to the specs, this translates to up to 57% in power savings, and based on what we’re seeing month over month, that claim doesn’t feel like a stretch at all. On top of that, it carries the Energy Star certification, which means we were able to look into government rebate programs to offset our initial investment – something we’d strongly encourage anyone considering this purchase to explore.
| Feature | Benefit | Impact on Bills |
|---|---|---|
| 22 SEER2 Rating | High efficiency standard | Lower monthly energy costs |
| Inverter Technology | No compressor on/off cycling | Up to 57% power savings |
| Eco Mode | Automatic energy optimization | Reduced idle consumption |
| Geo-Location Function | Adjusts temp based on location | No wasted energy while away |
| Energy Star Certified | Qualifies for rebates | Savings on upfront cost |
Beyond the core efficiency rating, we’ve been taking full advantage of features that quietly chip away at unnecessary energy use throughout the day. The geo-location function through the DELLA app automatically adjusts the temperature based on whether we’re home or away – no more forgetting to turn it off before leaving. We also rely on the eco energy saving mode, the 24-hour timer, and the sleep mode to keep things running efficiently around the clock without any manual effort. What we love most is that none of this efficiency comes at the cost of comfort – the system still heats and cools our space perfectly. If lower utility bills and smarter energy use matter to you, this unit delivers on both fronts.

Our Recommendations for Installing and Getting the Most Out of This Unit
One of the most important things we want to stress right away is that this unit requires professional installation – it is not a DIY system. The line-set must be vacuumed during installation, and if you need to extend or shorten the line-set beyond the included 16.4ft kit, a certified technician will need to adjust the R32 refrigerant levels accordingly. The included copper pipes measure 1/4″ and 1/2″ outer diameter, the drain pipe runs 78.7 inches, and the maximum fuse size is 20A. Getting these details right from the start will protect both the system’s performance and your warranty coverage. Here’s a quick reference for the key installation specs:
| Installation Detail | Specification |
|---|---|
| Included Line-Set Length | 16.4 ft |
| Max Pre-Charged Refrigerant Range | Up to 25 ft |
| Refrigerant Type | R32 (pre-loaded) |
| Maximum Fuse Size | 20A |
| Drain Pipe Length | 78.7 in |
| Voltage Requirement | 208V-230V |
Once installed, we recommend taking full advantage of everything this system has to offer to maximize both comfort and energy savings. Start by connecting it to the DELLA app via Wi-Fi and linking it to your Alexa or Google Home – the geo-location feature alone can make a noticeable difference on your energy bill by automatically adjusting the temperature based on whether you’re home or away. Set up the 24-hour timer and sleep mode to match your daily routine, and use Eco mode during mild weather to keep energy consumption low. Don’t overlook the seasonal filter cleaning either – it’s quick, the filters are reusable, and it keeps the PureClean tech working at its best. Since it’s Energy Star certified, make sure to look into available government rebates in your area to offset your investment.
- Use Eco and Sleep modes to reduce energy usage without sacrificing comfort
- Enable geo-location in the DELLA app for automatic temperature adjustments
- Clean reusable filters seasonally to maintain air quality and system efficiency
- Check for Energy Star rebates – this unit qualifies for government incentive programs
- Keep the outdoor unit clear in winter – the built-in bottom heating element handles defrost, but airflow around the unit still matters

Q&A
Q&A: Your Questions About the DELLA Serena 22 SEER2 Mini Split, Answered
We’ve received quite a few questions from our readers after publishing our review of the DELLA Serena 22 SEER2 Mini Split. We love hearing from you, and we want to make sure everyone has all the information they need before making such an important purchase. Below, we’ve rounded up the most common questions and answered them as thoroughly as we can.
Q: What size room is the DELLA Serena 22 SEER2 Mini Split suitable for?
A: This unit is designed to handle rooms up to 1,000 square feet, which makes it a great fit for a wide range of spaces. Whether you’re looking to cool or heat a large bedroom, an open-plan living area, a home office, or even a commercial space like a small store or restaurant, this system should have you covered. We found that it performed really well in larger rooms without breaking a sweat – pun intended!
Q: Can this mini split both heat and cool a room?
A: Absolutely! The DELLA Serena is a heat pump system, meaning it handles both heating and cooling. It can operate in heating mode down to temperatures as low as 5°F (-15°C), which is impressive for a unit at this price point. Whether you’re dealing with a sweltering summer or a frigid winter, this system has you covered year-round. That’s one of the things we appreciated most about it – it’s a true all-season solution.
Q: How energy efficient is this unit?
A: Very efficient! The DELLA Serena carries a 22 SEER2 rating, which is well above the minimum efficiency standards and puts it in the higher-performance category. It also features inverter technology, which means the compressor doesn’t constantly turn on and off. Instead, it adjusts its power output to match your needs, which DELLA claims can lead to up to 57% in energy savings compared to traditional units. On top of that, it’s Energy Star certified, so you may even be eligible for government rebates – something we’d encourage you to look into in your area.
Q: Is this unit compatible with Alexa and Google Home?
A: Yes, it is! The DELLA Serena integrates seamlessly with both Amazon Alexa and Google Home, so you can control it with simple voice commands. You can also manage it through the DELLA app from anywhere, which is a really handy feature if you want to pre-cool or pre-heat your space before you arrive home. There’s even a geo-location function that automatically adjusts the temperature based on your location – saving energy when you’re away and making sure things are comfortable when you get back. We think this smart home integration is one of the standout features of this unit.
Q: Does it come with a remote control?
A: Yes, it does! Even with all the smart features and app connectivity, DELLA hasn’t forgotten about the good old remote control. It’s included in the box, so you’ll always have a convenient way to adjust settings without reaching for your phone or speaking to a voice assistant.
Q: How loud is the DELLA Serena when it’s running?
A: This is one area where the DELLA Serena really shines. In mute mode, the indoor unit operates at just 22 dBa, which is whisper-quiet – roughly comparable to a soft whisper or a rustling of leaves. We were genuinely impressed by how silent it was during our testing. If noise is a concern for you, especially in a bedroom or office setting, you’ll be happy with this unit.
Q: What operating modes does the DELLA Serena support?
A: The DELLA Serena comes loaded with a wide variety of modes and features. Here’s a quick rundown of what’s available:
- Cooling mode – standard air conditioning
- Heating mode – for cold days and nights
- Auto mode – the system selects the best setting automatically
- Dry mode – helps with dehumidification
- Eco mode – prioritizes energy savings
- Sleep mode – maintains a comfortable temperature quietly overnight
- Turbo mode – quickly reaches your desired temperature
- I Feel mode – adjusts based on the temperature at the remote location
- 4D airflow – directs air both up/down and left/right
- 24-hour timer – schedule the unit to turn on or off as needed
- Multiple fan speeds – for personalized airflow
We found this variety of modes really useful for adapting to different comfort needs throughout the day.
Q: What is PureClean technology, and why does it matter?
A: PureClean is DELLA’s proprietary self-cleaning technology built into the indoor unit. It works to prevent dust buildup and defrosts the indoor coils, which helps keep the air cleaner and the system running efficiently. For the outdoor unit, DELLA has included a bottom heating element that prevents ice from forming during cold winter operation. Together, these features help maintain reliable performance and healthier air quality in your home. We think it’s a smart addition, especially for those in colder climates.
Q: Can I install the DELLA Serena myself?
A: We want to be upfront with you here – this is not a DIY mini split system. Professional installation is required. The system comes with a 16.4-foot installation kit that includes standard copper pipes (1/4″ and 1/2″ outer diameter) and a 78.7″ drain pipe, but line-set vacuuming is required during installation, and any changes to the line-set length will require adjusting the refrigerant levels. The maximum fuse size is 20A, and it requires a 208V-230V electrical connection. We strongly recommend hiring a licensed HVAC technician to handle the installation. It’ll ensure your warranty stays valid and that the system performs optimally from day one.
Q: Does the unit come pre-charged with refrigerant?
A: Yes! The DELLA Serena comes pre-loaded with R32 refrigerant, which is sufficient for line-set runs of up to 25 feet. If your installation requires a longer line-set, you’ll need to have additional refrigerant added by your HVAC professional during installation.
Q: What kind of warranty and support does DELLA offer?
A: DELLA offers a lifetime warranty on this unit, which is a bold and reassuring commitment. They also provide 24/7 live chat support, so if you ever run into an issue or have a question, help is just a message away. That level of customer support gives us a lot of confidence in recommending this product.
Q: Is the DELLA Serena eligible for any government rebates?
A: Because it’s Energy Star certified, you may qualify for government energy efficiency rebates in your area. Rebate programs vary by state, utility provider, and local government, so we’d recommend checking with your local energy provider or visiting the Energy Star website to see what’s available to you. It could be a great way to offset some of the upfront cost!
