Della and Tehanld Mini Split Comparison

Coverage area

Edge: Tehanld 12000 BTU Mini Split

The Della Vario Series is rated for spaces up to 550 square feet. This capacity aligns with its 12,000 BTU output and 23 SEER2 efficiency rating. The Tehanld unit covers a larger area of up to 750 square feet. This wider range is notable given it uses a lower 17 SEER2 efficiency rating. You should match the square footage of your room to these limits. If you have a larger open space, the Tehanld coverage is more suitable. For smaller rooms, the Della provides adequate cooling without oversizing the system.

Energy efficiency

Edge: DELLA Vario 12K BTU 23 SEER2

Efficiency matters for your long-term electricity usage. The Della Vario Series boasts a 23 SEER2 rating. This is a high number for a 12,000 BTU unit. It also has a 9.5 HSPF rating for heating efficiency. The Tehanld unit operates at 17 SEER2. While still efficient due to R32 refrigerant, it is significantly lower than the Della. Higher SEER2 ratings generally mean lower energy consumption for the same cooling output. If reducing your power bill is a priority, the Della offers superior efficiency performance.

Voltage requirements

Edge: Tehanld 12000 BTU Mini Split

Your home’s electrical setup dictates which unit you can install. The Della Vario Series requires a 230V connection. This is standard for many mini splits but may need a dedicated circuit upgrade in some homes. The Tehanld model is available in a 115V version. This allows it to plug into standard household outlets in some configurations, though professional installation is still required. Check your breaker panel before deciding. If you only have standard 115V outlets nearby, the Tehanld is the more flexible choice for easier integration.

Smart control

Edge: DELLA Vario 12K BTU 23 SEER2

Both units offer remote control, but Della adds voice compatibility. The Della Vario Series works with Alexa. You can adjust settings using voice commands if you have compatible smart home devices. The Tehanld unit relies on a multi-function remote control. It does not list voice assistant integration in its specifications. If you prefer controlling your climate through voice commands or smart routines, the Della provides that extra layer of convenience. Otherwise, the standard remote on the Tehanld handles basic adjustments adequately.

Operating modes

Edge: DELLA Vario 12K BTU 23 SEER2

The Tehanld unit lists five specific flexible modes: Cool, Heat, Auto, Fan, and Dry. It also includes four adjustable fan speeds. The Della Vario Series mentions multiple fan speeds and modes like sleep, eco, and auto defrost. It also features an I feel mode for remote temperature sensing. While Tehanld explicitly lists five modes, Della’s feature set includes specialized functions like intelligent compressor pre-heating and self-cleaning. Both offer comprehensive control. The Della’s I feel mode offers a unique comfort advantage by sensing temperature at the remote.

Noise level

Edge: DELLA Vario 12K BTU 23 SEER2

Quiet operation is important for bedrooms or living areas. The Della Vario Series is rated at 28 dBa. This is a very low noise level, described as ultra silent. The Tehanld unit mentions a Quiet Mode and low-decibel environment but does not provide a specific decibel rating in its specifications. Without a number, it is hard to compare directly. However, 28 dBa is exceptionally quiet for an indoor unit. If silent performance is your top priority, the Della provides a verified low-noise specification that Tehanld lacks.
