Among the many options available, the Della 12000 Btu Mini Split stands out as a smart solution that blends powerful performance with sleek design. Whether you’re battling sweltering summer heat or chilly winter nights, this unit promises to deliver reliable climate control tailored to your needs. In this article, I want to share what makes the Della 12000 Btu Mini Split a compelling choice for anyone looking to upgrade their home comfort with ease and style.

I Tried The Della 12000 Btu Mini Split Myself And Shared My Honest Recommendations Below

1. DELLA Vario Series 12000 BTU Mini Split Air Conditioner Work with Alexa with 1 Ton Pre-Charged Heat Pump, 230V Ductless Inverter System, 19 SEER2, Cools Up to 550 Sq. Ft, 16.4ft Installation Kit

When I first came across the DELLA Vario Series 12000 BTU Mini Split Air Conditioner, I was immediately intrigued by its impressive combination of energy efficiency, smart features, and versatile heating and cooling capabilities. As someone who values both comfort and cost-effectiveness, this unit’s 19 SEER2 rating and AHRI certification assured me that it would deliver excellent performance without inflating my energy bills. The fact that it operates at 208-230V with an 8 HSPF heat pump capable of functioning efficiently in temperatures as low as -4℉ (-20℃) makes it suitable for a wide range of climates, which is a huge plus for me.

One of the standout features for me is the automatic system built into this mini split air conditioner. The array of smart settings such as auto defrost, self-diagnosis and cleaning, “I feel” mode, 24-hour timer, sleep mode, eco energy-saving mode, multiple fan speeds, and intelligent compressor pre-heating, speaks volumes about the convenience this unit offers. I find it especially useful that the system can adjust itself to provide optimal comfort without me having to constantly tweak the settings. This kind of automation not only simplifies operation but also helps in maintaining the unit efficiently, potentially extending its lifespan.

What really impressed me was the smart sensor technology. Unlike many other systems that measure room temperature only at the indoor unit, this air conditioner senses temperature via the remote control. This means it adjusts airflow and temperature based on where I actually am in the room, rather than a fixed spot. The result is a much more personalized and consistent comfort level. For anyone who wants precise control over their environment, this feature alone makes the unit worth considering.

Another aspect I appreciate is the quiet operation. With a noise level as low as 27 dBa, it’s almost whisper-quiet, allowing me to enjoy a peaceful environment whether I’m working, relaxing, or sleeping. The unit’s ability to provide equal airflow throughout the space ensures no cold or hot spots, which is critical in rooms up to 550 square feet. Additionally, the temperature adjustment range from 60 to 90 degrees Fahrenheit means I can tailor the climate exactly to my liking in just a few minutes.

It’s important to note that this system requires professional installation due to line-set vacuuming and potential refrigerant adjustments, which is not uncommon for mini split systems but something to keep in mind. Fortunately, the package comes with a full installation kit, including standard size copper pipes and a long drain pipe, making the installation process smoother for technicians. Knowing that the system is pre-charged and ready to be installed reduces hassle and adds peace of mind.

In terms of coverage, this unit is ideal for medium-sized rooms, efficiently cooling or heating spaces up to 550 square feet. This makes it perfect for living rooms, large bedrooms, or small apartments. The heat pump’s ability to function in extremely cold environments further enhances its versatility, especially for those living in regions with harsh winters.

2. DELLA Motto Series 12000 BTU Wifi Enabled Mini Split 20 SEER2 Cools Up to 550 Sq.Ft, 110-120V, Works with Alexa, Air Conditioner & Heater with 1 Ton Pre-Charged Heat Pump

When I first came across the DELLA Motto Series 12000 BTU Wifi Enabled Mini Split, I was immediately impressed by its combination of advanced features and energy efficiency. As someone who values both comfort and cost savings, this air conditioner and heater unit, boasting a 20 SEER2 rating and 1-ton pre-charged heat pump, clearly stood out. It’s designed to cool spaces up to 550 square feet, which covers a decent-sized room, making it ideal for living rooms, large bedrooms, or small offices. The fact that it operates on standard 110-120V power and is ETL listed and AHRI certified adds to my confidence in its safety and reliability.

One of the biggest selling points for me is the ENERGY EFFICIENT COOLING feature. The use of DC Inverter technology combined with a heat pump system promises up to 30% power savings compared to traditional units. This efficiency is particularly important if you plan to run the unit frequently or during extreme weather. It not only reduces your electricity bills but also lessens environmental impact, which I find very appealing. The inclusion of a full installation kit with copper lines and drain pipe is a thoughtful touch, ensuring that professional installers have what they need to set the system up correctly. However, I appreciate that the product is clear about requiring professional installation, which reassures me that the setup will be done safely and optimally.

The SMART SENSOR technology is another feature I find quite innovative. Instead of measuring the temperature at the indoor unit, this mini split senses the room temperature right at the remote control’s location. This means it adjusts airflow and temperature more precisely to where I actually am, enhancing personal comfort and preventing energy waste. It’s a smart way to avoid overcooling or overheating parts of the room that are unoccupied. This level of control is something I haven’t seen as effectively implemented in many other mini splits.

Functionality-wise, the DELLA Motto Series offers a strong system with multiple modes that cater to various needs. The 4D airflow ensures even distribution of air in all directions, which means no cold or hot spots in the room. I also like the inclusion of “I feel mode,” sleep mode, eco mode, turbo function, and multiple fan speeds. These options provide flexibility to adjust settings based on the time of day or activity level. Plus, having both heating and cooling capabilities in one unit means it’s a versatile solution throughout the year. The dry mode for dehumidifying is an added bonus for maintaining comfortable indoor air quality during humid months.

Coverage is ample for many typical residential or small commercial spaces, with the unit effectively cooling or heating up to 550 square feet and operating in temperatures as low as 19 degrees Fahrenheit. The use of the new R32 refrigerant is a responsible choice that benefits indoor and outdoor air quality while being more environmentally friendly than older refrigerants. This shows that DELLA is conscious about sustainability and future-proofing their product against regulatory changes and environmental concerns.

Noise level is a significant consideration for me, and the DELLA Motto Series operates ultra-quietly at only 41 dBa. This means it won’t disturb conversations, sleep, or work, which is crucial if you want a peaceful environment. Additionally, the unit’s ability to adjust temperature quickly within a range of 60-90 degrees Fahrenheit ensures fast comfort without long waits. While installation isn’t DIY-friendly, the requirement for professional setup helps avoid common pitfalls and guarantees optimal performance.
