Della vs Mrcool Mini Split Specs
Coverage area
Edge: MrCool DIY Select 12K BTU
The Della Vario 12K BTU is rated for up to 550 square feet. It uses a 16.4-foot standard line set to deliver cooling and heating to that specific zone. MrCool DIY Select covers a broader range, handling spaces from 500 to 1,200 square feet. This wider capacity range allows the MrCool unit to manage larger rooms or open-concept areas more effectively. If you need to cool a bigger space, the MrCool specification offers more flexibility. The Della unit is better suited for smaller, defined rooms.
Energy efficiency
Edge: DELLA Vario 12K BTU 23 SEER2
Efficiency ratings determine how much electricity each unit uses to maintain your desired temperature. The Della Vario achieves a 23 SEER2 cooling rating and a 9.5 HSPF heating rating. These numbers indicate high performance for both cooling and heating seasons. The MrCool DIY Select offers a 17.5 SEER2 cooling rating and an 8.8 HSPF2 heating rating. While still efficient, these figures are lower than Della’s. Higher SEER2 and HSPF values generally mean lower operating costs over time. Della provides superior energy efficiency specs in this comparison.
Smart control
Edge: Tie
Control methods vary significantly between these two mini splits. The Della Vario works with Alexa for voice control. It also features a smart sensor in the remote that measures temperature at your location rather than at the wall unit. This allows for personalized comfort adjustments. The MrCool DIY Select includes Wi-Fi capability for remote monitoring and adjustment via the MrCool Comfort App. It also comes with a standard remote control. If you prefer voice commands or localized temperature sensing, Della is the choice. If you want app-based management, MrCool fits that need.
Noise level
Edge: DELLA Vario 12K BTU 23 SEER2
Quiet operation is important for bedrooms and living areas. The Della Vario operates at an ultra-quiet 28 dBa. This low decibel level ensures it runs silently in the background. The MrCool product data does not list a specific decibel rating for its indoor unit. Without this specification, you cannot directly compare the noise output. Della provides a clear advantage here with its published quiet operation spec. You can expect minimal disruption to your daily routine with the Della unit.
Installation type
Edge: MrCool DIY Select 12K BTU
Installation requirements differ based on the system design. The Della Vario mandates professional installation. It requires line-set vacuuming during setup, and any alteration to line-set length requires adjusting freon levels. This is not a DIY project. The MrCool DIY Select is designed for do-it-yourself installation. It includes a pre-charged quick-connect line set, eliminating the need for professional refrigerant handling. This makes setup straightforward for those with technical skills. MrCool offers a more accessible installation process for independent users.
Physical build
Edge: Tie
The physical dimensions and weight affect where you can mount the indoor unit. The Della Vario measures 31.9 inches wide, 11.5 inches high, and 8.07 inches long. It weighs 61 pounds. The MrCool DIY Select is 28.4 inches wide, 19.5 inches high, and 10.6 inches long. It weighs 132 pounds. MrCool is wider and taller but significantly heavier. Della is narrower and lighter, which may make mounting easier. Choose Della for a slimmer profile. Choose MrCool if you have a sturdy wall capable of supporting the heavier unit.
