Vario vs Econo Side-by-Side
Coverage Area
The Della Vario Series 12000 BTU is designed for smaller spaces, providing cooling and heating for up to 550 square feet. In contrast, the Della Econo Series 17000 BTU handles significantly larger areas, covering up to 1000 square feet. This difference in capacity means the Econo model is better suited for open-concept living rooms or larger master bedrooms. You should choose the Vario if your space is compact, but opt for the Econo if you need to condition a bigger room. The larger footprint of the Econo unit reflects its higher output.
Efficiency Rating
Energy efficiency is a key specification for any mini split. The Della Vario Series achieves a 23 SEER2 rating, which is notably higher than the 17 SEER2 rating of the Della Econo Series. A higher SEER2 number indicates better energy efficiency during cooling operations. This means the Vario model likely consumes less electricity to produce the same amount of cooling compared to the Econo. If your priority is minimizing energy usage for a given space, the Vario offers a clear advantage. The Econo is less efficient but provides more raw cooling power.
Smart Control
Both units support Alexa voice commands, but their connectivity options differ. The Della Econo Series includes built-in Wi-Fi and app control, allowing you to manage settings remotely via a smartphone. The Della Vario Series lists Alexa compatibility but does not explicitly mention built-in Wi-Fi or app control in its provided specifications. This means you may need a separate smart plug or hub to control the Vario remotely, whereas the Econo offers native app integration. For users who want direct smartphone management, the Econo is the superior choice.
Operating Temperature
Cold weather performance varies between these two models. The Della Vario Series is rated to operate in environments as low as -4 degrees Fahrenheit. The Della Econo Series is rated for temperatures down to 5 degrees Fahrenheit. This 9-degree difference means the Vario can provide heating in colder climates where the Econo might shut off or struggle. If you live in an area with freezing winters, the Vario’s lower operating limit makes it more reliable for year-round use. The Econo is suitable for milder winter conditions.
Noise Level
Quiet operation is important for bedroom or office use. The Della Vario Series operates at a noise level of 28 dBa, which is very silent. The Della Econo Series runs at 32 dBa. While both are considered quiet, the Vario is noticeably quieter by 4 decibels. This difference may be perceptible in a very quiet room. If you are sensitive to background noise, the Vario provides a more peaceful environment. The Econo is still quiet but slightly louder due to its larger compressor and fan size required for higher output.
Physical Dimensions
Installation space and aesthetics matter when mounting the indoor unit. The Della Vario Series measures 31.9 inches in width, while the Della Econo Series is wider at 35.8 inches. Both units have similar heights and depths, around 11.5 inches. The Vario is more compact horizontally, making it a better fit for smaller walls or narrower alcoves. The Econo’s wider design may require more wall space. If you have limited wall area, the Vario’s smaller footprint is a practical advantage. Both are white and sleek.
Which mini split fits your home
Small room owners seeking efficiency
The Vario Series offers 23 SEER2 efficiency for its 12,000 BTU capacity. This high rating ensures lower energy use for spaces up to 550 square feet. It also operates quietly at 28 dBa. You get precise temperature control via the smart sensor in the remote. It is ideal if you prioritize quiet operation and energy savings in a compact area.
Large space owners needing power
The Econo Series provides 17,000 BTU to cool up to 1000 square feet. This higher capacity handles larger rooms or open plans effectively. It includes 4D airflow for better air distribution. The unit supports Wi-Fi and app control for remote management. It is the better choice when you need substantial cooling power for a bigger footprint.
Users wanting advanced app control
The Econo Series includes built-in Wi-Fi and app connectivity alongside Alexa support. This allows you to monitor and adjust settings directly from your smartphone. The Vario model only lists Alexa compatibility without explicit app control in its features. If you want full remote management via a dedicated app, the Econo Series provides that specific capability.
