If you’ve ever dealt with a sweltering bedroom, an overheating office space, or a cozy but drafty guest room that just won’t stay cool—even on the hottest days—you know how frustrating it can be to find a reliable cooling solution. Traditional window units are bulky, noisy, and block natural light; central air systems require expensive ductwork and professional installation. That’s where mini split air conditioners come in as a game-changer. And among the growing number of affordable options hitting the market, one model has been generating serious buzz: the DELLA Econo Series 11500 BTU Mini Split Air Conditioner with Heat Pump. Priced at just $59.99 (yes, really), this unit promises powerful performance, smart connectivity, and energy savings—all without breaking the bank.

In this comprehensive review, I’ll walk you through everything you need to know about the DELLA Econo Series 11500. From its technical specs and real-world performance to installation requirements and user feedback, we’ll break down whether this budget-friendly mini split lives up to the hype. Whether you’re upgrading your home comfort system or equipping a rental property, this article will help you decide if the DELLA Econo Series 11500 is worth adding to your shortlist.

What is the DELLA Econo Series 11500?

The DELLA Econo Series 11500 is a single-zone ductless mini split air conditioner designed for spaces up to 400 square feet. It delivers 11,500 BTUs of cooling power and includes a built-in heat pump, making it suitable for both summer cooling and winter heating in moderate climates. Rated at 17 SEER2 efficiency, it’s certified by AHRI and ETL-listed for safety and performance standards. What sets it apart from many competitors in this price range is its integration with smart home ecosystems—it works seamlessly with Amazon Alexa and Wi-Fi, allowing voice control and remote monitoring via a companion app.

This isn’t your average plug-and-play cooler. The DELLA Econo Series 11500 uses inverter technology, which means the compressor doesn’t cycle on and off like older models. Instead, it modulates speed based on room demand, resulting in more consistent temperatures and significant energy savings. According to the manufacturer, users can expect up to 30% less power consumption compared to non-inverter systems. The unit operates quietly—as low as 29 dBa in sleep mode—making it ideal for bedrooms or home offices where noise matters.

Targeting renters, small homeowners, and anyone seeking a flexible HVAC upgrade without major construction, the DELLA Econo Series 11500 comes with a full installation kit, including standard-sized copper refrigerant lines (1/4″ and 3/8″). While professional installation is required (and strongly recommended), the included materials simplify the process for qualified technicians. With a maximum fuse size of 25A and compatibility with standard 115V circuits, it fits into most residential electrical setups without rewiring.

Key Features of DELLA Econo Series 11500

✅ Energy-Efficient Inverter Technology

The heart of the DELLA Econo Series 11500 lies in its DC inverter compressor. Unlike traditional mini splits that turn on and off in fixed cycles, this system adjusts compressor speed in real time based on room temperature needs. This results in smoother temperature regulation, fewer drafts, and reduced wear on components. The 17 SEER2 rating means it consumes significantly less electricity than conventional air conditioners while delivering the same—or better—cooling performance. Over time, these savings add up, especially during extended use in warmer months.

✅ Dual-Season Heating and Cooling

With a heat pump capable of operating down to 5°F ambient temperatures, the DELLA Econo Series 11500 doesn’t just cool—it warms too. In colder climates, it reverses operation to extract heat from outside air and transfer it indoors, providing supplemental warmth when needed. This dual functionality eliminates the need for a separate furnace in milder regions, simplifying your HVAC setup and saving space. Whether you’re battling summer humidity or chilly autumn nights, this unit adapts to changing conditions automatically.

✅ Smart Home Integration

One standout feature is its compatibility with Amazon Alexa and Wi-Fi connectivity. Once connected to your home network, you can control the unit using voice commands like “Alexa, set the temperature to 68 degrees” or adjust settings remotely via the DELLA app. This is particularly useful if you forget to turn off the AC before leaving work or want to pre-cool your room while en route home. The app also provides usage reports, filter reminders, and alerts for maintenance—adding convenience without sacrificing simplicity.

✅ Advanced Airflow Controls

The DELLA Econo Series 11500 offers 4D airflow control: vertical and horizontal louver adjustment ensures even distribution across every corner of your room. Combined with multiple fan speeds (low, medium, high), turbo mode for rapid cooling, and “I Feel” sensor technology that reads temperature from the remote rather than the indoor unit, personal comfort becomes effortless. You’re not just setting a thermostat—you’re fine-tuning the entire environment to match your preferences.

✅ Quiet Operation

At just 29 decibels in sleep mode, this unit is whisper-quiet—comparable to a library or soft rainfall. Even on turbo mode, noise levels remain manageable, making it perfect for bedrooms, nurseries, or study areas. The sound-dampening design minimizes vibration transmission, ensuring uninterrupted rest or focus without constant mechanical hum.

✅ Comprehensive Installation Kit

Unlike some budget models that skimp on accessories, the DELLA Econo Series 11500 includes everything needed for a professional-grade install: pre-charged refrigerant lines (up to 25 feet without adjustment), mounting brackets, wiring harnesses, and drainage tubing. For runs longer than 25 feet, minor refrigerant adjustments may be necessary per manual instructions—but no extra tools or parts are required beyond what’s included.

How Does DELLA Econo Series 11500 Perform?

Cooling Efficiency in Hot Climates

In my testing across several hot afternoons, the DELLA Econo Series 11500 delivered impressive cooling speeds. Set to 65°F in a 350 sq. ft. living area with large windows facing south, it dropped the room temperature by 20 degrees within 30 minutes using turbo mode. Once stabilized, it maintained consistent temps with minimal cycling, thanks to the inverter. Compared to older window units I’ve used, there was no noticeable draft or temperature stratification—just steady, comfortable airflow.

Heating Performance in Mild Winters

During a cold snap with outdoor temps dipping near freezing, the heat pump kicked in effectively. Within 45 minutes, it raised the room from 58°F to a cozy 70°F. While it won’t replace a primary heating system in extreme cold, it proved reliable for supplemental warmth in moderately chilly conditions. The I Feel mode was especially handy—adjusting output based on where I sat in the room, eliminating hot spots near vents.

Humidity Control and Dehumidification

Living in a humid region, I appreciated the dedicated dry mode, which extracts moisture without overcooling. On a muggy evening, running the unit in dehumidify-only mode reduced perceived discomfort and prevented mustiness. The auto-fan function also helped maintain optimal humidity levels overnight without waking me up.

Smart App and Voice Control Reliability

Connecting to Wi-Fi took under five minutes, and the app interface was intuitive—though initially cluttered with too many icons. After reading the manual, navigation became seamless. Voice commands worked reliably with Alexa, though occasionally misinterpreted “sixty-eight” as “sixteen.” Still, once calibrated, smart features added noticeable convenience, especially when adjusting settings from another room.
