Some features I like from Della mini splits
Highest operating temperature of 122°F
The Della Tri-Zone 27K BTU model, for example, is consistent even in extreme climates (think Fairbanks, Alaska), thanks to its wide temperature range.
As long as proper maintenance is in play, Della's mini split air conditioning system's capacity to operate reliably at temperatures up to 122°F suggests they are engineered for consistent performance even under harsh hot conditions.
Turbo mode
All Della mini splits have a turbo mode. Della claims the turbo mode on its mini splits increases cooling power by 40% and reduces startup by 33%.
From my assessments, the turbo mode increased the fan speed to accelerate the cooling and heating process.
I could reach a preset temperature in the shortest possible duration, as it operated for 10-30 minutes before returning to normal mode.
One snag I noted with this feature is that it consumed a lot of energy.
Air is pre-cooled before blowing
Units have a smart remote that can be programmed to keep the air flowing and at a set humidity level, even when not cooling. Keeping the air dry and between 40 - 55% Relative Humidity can save on cooling costs and ensure maximum comfort.
If you want the air in your room to feel drier during sleep hours, the Della air conditioning units do exactly that.
The entire Della lineup packs this function, reducing the time needed to achieve the desired temperature.
Smart sensor for adjusting air flow
The smart sensor could detect my room occupancy and adjust airflow accordingly.
It syncs with the system's thermostat to ensure the desired amount of cool or warm air remains consistent.
I didn't have to adjust the airflow direction manually since the system automatically adapts the airflow based on the remote control's direction.
All Della models I tested, from the 9K BTU JA series to the 36K BTU Multi-Zone, had a smart sensor that optimized energy efficiency by allowing the mini-split system to operate at a lower capacity anytime I didn't occupy my living space.
Ductless pre-charged inverter system
Due to their ductless pre-charged inverter system, I don't do pricey ductwork for every Della mini split system I install.
Mini-splits use variable-speed compressor technology to adjust heating or cooling output, which helps avoid energy losses associated with the ductwork of the central forced air system.
During installation, all I had to do was link individual units to an outdoor compressor, with the indoor unit packing built-in evaporator coils cooled with the refrigerant line that's already charged.
R-32 refrigerant
I consider R-32 refrigerant the most balanced fluid for energy efficiency, safety, and environmental impact. Compared to R410A and R290, I find it to have better heating performance.
Not all Della mini split systems have the R-32 refrigerant. For instance, models in the Multi-Zone and TL series use R410A refrigerant.
The R-32 feature is only limited to models in the JBP series.
Alexa and WiFi enabled
With Alexa integration, I could use voice commands to adjust the temperature, change modes, or turn the unit on/off without getting up.
The WiFi connectivity adds convenience since Della mini split systems integrate with other smart home devices via the Della + app.
Usage monitoring, adjusting temperature based on location, and scheduling were among other features I tested on Alexa and WiFi-enabled Della models.
Ulta quiet operation
I've seen Della mini split systems producing noise levels ranging from 22-55+ dB, depending on the fan speed.
At its lowest fan settings, the 9,000 BTU model, for instance, will operate at or below 30 dB, which I find incredibly quiet and unobtrusive.
The 18K BTU JA Series was also relatively silent at 47 dB but was a bit noisier as I ramped up the fan settings.
How does the energy efficiency compare to other brands?
Understanding SEER and EER ratings
SEER (Seasonal Energy Efficiency Ratio) represents the cooling output during a typical cooling season, divided by the total electric energy input during the same period.
In contrast, EER (Energy Efficiency Ratio) measure the ratio of the cooling capacity (in BTUs) to the power input (in watts) at a specific temperature point, usually 95°F.
For both ratings, the higher the number, the more efficient the model is. For real world purposes, SEER is probably more accurate.
Della mini split efficiency scores
I've seen Della mini splits with higher SEER and EER ratings translate to lower operational costs. I suggest buying an energy-efficient Della air conditioning unit with a minimum rating of 14.
All the Della mini splits I've included here have SEER ratings ranging from 17 to 20, signaling their energy efficiency.
The EER ratings here are also between 9 and 12, depending on the mini-split heat pump model.
The company is also working on releasing even more efficient units, competitive with other mini split brands like Senville.
Tax credits and incentives
To enjoy various state and federal tax credits, I recommend buying a high-efficiency model in Della's lineup, such as those in the JBP series.
For instance, the 20 SEER JBP mini-split AC could bag up to $300 federal tax credit. Always check your specific model before installation.
Della's SEER ratings are fairly competitive when placed head-to-head with other notable brands.
Comparison to competitors
Daikin hit SEER levels of up to 17.7, while LG mini split models ranged from 17.0 to 27.5 during my tests.
Mitsubishi mini split AC systems are at the top, with ratings of 19.1 to 33.1.
Upfront cost vs long-term savings
While some brands have higher SEER ratings, the standout element with Della is its pricing tends to be lower, especially for their mid-tier and entry-level models.
Of course, the tradeoff with higher efficiency is the initial investment.
Pricier Della models, such as those in the Multi-Zone or JBP series, have an energy-efficient design that boosts their reliability in the long term.
Buying a premium model is an excellent choice since the long-term energy savings can justify the higher initial price tag, assuming you'll use the unit for 10 years or more.
Analyzing their warranty terms and conditions
What's the warranty coverage?
The Della mini split models I have included here come with a 1-year limited coverage that starts from your order receipt date.
Its mini spit AC lineup includes a 5-year warranty for the compressor and a 3-year warranty for the parts and labor.
While Della Home's warranty covers accidental damage, breakdowns, and 25/7 support, the mini split brand isn't liable for indirect or incidental damages.
I recommend working with a professional during installation to get the hang of how the model works since the coverage excludes damage due to incorrect operation or maintenance.
What registration requirements did I do to get the full warranty coverage?
As is with other warranty terms from notable mini split brands I've tested, Della asked for an invoice or receipt as proof of purchase.
I've helped homeowners register their warranty here by filling in personal details like name, email, and home address.
When registering for the full warranty coverage, I had to include the order number, where I purchased the unit from, product serial number, dealer name, installer's name, HVAC license, and more.
What conditions and restrictions did I have to meet?
First, replacing a defective compressor from a Della unit I had installed for a client was under the condition that the defect occurred within 1 year from the date of purchase.
We had to make a claim via an authorized retailer since the warranty isn't transferable under any circumstances.
Also, a Della employee called to request a digital image of the defect.
How does it measure up to the competition?
Both Della and Pioneer offer a 5-year warranty for the compressor and an additional 1-year warranty for parts and labor.
Senville tends to have a longer warranty for the compressor, which stands at 7 years.
Since Della has a limited warranty, there are limitations on what malfunctions could be covered.
Unlike Pioneer, where you can directly claim in writing, you must consult an authorized retailer if your Della unit suffers a manufacturer defect.
Overview of Della mini-split models
Here, I'll review Della's mini-split lineup. It seems that the company is in the process of renaming their series, so this can get slightly tricky.
As a quick reference, remember:
- The JA Series is also called the Motto Series
- The TL Series is also called the Versa Series
- The JPB Series is also called the Umbra Series
I love that I can easily control models on each series via the free DELLA+ app from any point with WiFi connectivity.
All models also have Gold Fin™ technology for longevity to protect the condenser coils from harsh weather.
I tested the turbo function, and the fast cooling/heating was timely.
Other notable features that impressed me include multiple fan speeds, air filtration, inverter-driven compressors, and heat pump capabilities, all of which I'll discuss further.
1. Multi-Zone Series
The mini splits in the Multi-Zone Series cost between $1,700 and $2,700.
I have heated up to 800 sq. ft. of living space with their lowest-tier model, which has a heating capacity of 18,000 BTU.
The compact AC mini split can heat up to 90 °F and cool down to 60 °F without a fuss. All models in the Multi-Zone tier had a built-in dehumidifier and air filtration features.
2. TL Series (Versa Series)
I find models in the TL Series low-priced, but their cooling power is also modest.
If I'm looking to spend less than $650 on a mini split air conditioner with a cooling capacity of 9000 BTU, this would be the right tier.
I have also seen models in this category with serious cooling capacity as high as 36,000 BTU.
Their 9K BTU model has enough capacity to heat, cool, and purify up to 400 square feet.
I recommend this unit to homeowners looking for a nifty remote control, solid energy savings, and the best model for cooling open floor plans.
3. JA Series (Motto Series)
Thanks to the R32 Refrigerant feature on JA Series units, I bagged notable energy savings during my tests.
This would be my go-to series for spaces up to 500 square feet that require a multi-zone system with automatic dehumidification.
4. JPB Series (Umbra Series)
The JPB Series models impressed me with their lowest operating temperature of 5 °F.
With the turbo mode on, I've seen models in this range surge their cooling power while reducing the startup time.
The installation kit also comes complete, which helped me spend less time during installation.
The models I reviewed also had an Intelligent Defrost feature for automatically heating up the coils.
5. Other Della mini split series to check out
While the series I have mentioned already are the most popular choices for Della units, you are not without choice when it comes to a Della Mini Split. Here are three other series that they have, and what you can expect from each:
Della mini split AC models compared
Della TL Series (9K BTU model)
Main features:
If all I need is basic cooling and heating in a room under 400 sq. ft., the 9,000 BTU model would suffice.
This unit uses the R410A refrigerant, meaning it's slightly less energy efficient than models in the Multi-Zone series running on R32.
Unlike models in the Multi-Zone series, this is a more budget-friendly option within the Della range. You get a compact design but a slightly lower SEER rating.
JBP Series (12K BTU model)
Main features:
This is my go-to midrange option if I want a ductless mini split model for heating or cooling a medium-sized space of about 500 square feet.
A 19 SEER rating suggests that it's pretty energy-efficient.
It packs better efficiency than models in the TL and JA series. For an ultra-quiet operation, this model uses inverter technology.
JA Series (18K BTU model)
Main features:
For efficient climate control in larger spaces (up to 750 sq. ft.), the JA Series 18K BTU model would suffice.
It features a higher cooling capacity than the 9K TL or 12K JPB Series models, making it optimal for open-layout areas.
Thanks to its Gold Fin technology, you won't have to deal with rust issues, a poor defrosting process, or inconsistent heating efficiency.
Multi-Zone Series ( 36K BTU Quad-zone model)
Main features:
The Quad-Zone model has the highest cooling capacity and unmatched zoning capabilities compared to other Della models.
If the budget allows, I'd pick this heavy hotter for a multi-level home with zoned climate control.
This ductless system maintains maximum comfort while reducing energy consumption, thanks to its high 19 SEER rating.
Its high-temperature sterilization function was a first-rate selling point.
I didn't have to do this manually since the Della app always pushed an automatic filter cleaning reminder.
Installation explained for homeowners
I often get asked to estimate installation costs, give tips, and share insights on how to find a dependable HVAC professional.
Here's the full scoop on how to go about installing a Della mini-split system:
Guide to installation fees
I've seen local labor rates, the type of mini-split system, and the number of zones or units contributing significantly to the final installation cost.
A single-zone Della unit costs between $1,500 and $8,000+, with compact 9,000 BTU models costing less than larger 18,000 BTU or multi-zone options.
In lower labor cost areas like Cleveland, a 12,000 BTU install is $1,800-$2,500, with labor making up $400-$800.
But, that same 12K BTU unit could reach $3,000-$4,500 in high-cost areas like San Francisco.
Even in smaller markets, there's variance—a 36K BTU 4-zone system costs $7,000-$8,000 in Asheville versus $5,500-$6,500 in rural Morgantown.
Structural modifications and the number of air handlers also impact total fees.
How to find a reliable HVAC professional
Vetting an HVAC company is a safety net, and here's how I'd go about it:
Mini split AC installation tips
Use this as a checklist to ensure the HVAC professional meets industry standards during installation:
Troubleshooting tips
Problem | Cause | Solution |
|---|---|---|
Della mini split error code E5 | Communication problem between air handler and heat pump | Generally, a minimal electrical signal or a glitch in the start-up process causes the code. If a system reset doesn’t remove the error code, you must call a qualified maintenance specialist. |
Della mini split output low | Airflow is blocked | Clean vents, coils, and air filters to improve airflow. |
Della mini split doesn’t turn on | Tripped breaker | Check the circuit breakers for a tripped breaker and restore the power. |
Della mini split is on but not cold | Tripped breaker | Check coils and filters and clean as needed. If airflow is good, call a professional to test the refrigerant levels. |
Della vs other mini split brands
Here's how Della mini split models stack up against competitor brands:
Della vs Senville
Senville has an edge if I compare their top-tier models since they have a quad-zone SENA-48HF 48K BTU mini split.
It's pricier than Della's Multi-Zone 36K BTU model but churns more heating and cooling power.
I also found Senville to have a wider range of models, while Della is best for budget models, such as the 9K BTU JA Series mini split system.
I'd pick Senville if I want to heat or cool a larger space and go for Della if installation flexibility tops my checklist.
Senvlle's flagship models have SEER ratings of up to 22, while Della's most efficient unit stands at 22.
I witnessed better heating efficiency with the SENA-48HF 48K BTU mini split.
I didn't see any notable differences in their remote control features since both have WiFi connectivity, multiple fan modes, and a responsive mobile app.
All their high-end models that I reviewed also featured energy-efficient inverter technology, quiet operation, and built-in dehumidifiers.
Della vs Pioneer
Pioneer's Hyperformance series has more advanced features than Della's premium model.
On the Hyperformance series, I was wowed by its air quality sensors, which are easy to prompt via Alexa or Google Assistant.
I'd say Della's premium models, like those in the JA Series, have standard features like auto-restart and programmable features.
At 24.5 SEER, I could retain up to 88% of heating capacity in low single-digit weather on Pioneer's most elite ductless mini split.
And that suggests it's more energy efficient than Della's quad-zone model.
Pioneer's 18K BTU Diamante series also excelled in low noise output, running as low as 19 decibels on low fan speed.
Della's 18K JA series got stuck at 22dB while running on its lowest fan speed.
If you're not cash-strapped, I'd pick any of Pioneer's premium models, as their ultra-high efficiency would offset costs through lower energy bills in the long term.
Della has more than enough on its lineup for homeowners who need a budget-friendly mini-split system.
