The price difference between two mini splits means little if one is the wrong size for your room. In the DELLA Econo vs Motto comparison, Econo occupies the base-model tier, while Motto sits in the efficiency tier. Econo deserves a look when a correctly sized model lowers your upfront cost; Motto deserves a look when its higher cooling-efficiency rating or an available 115V configuration fits your project.
Neither series is limited to one room size. Both include smaller and larger single-zone systems, so a bedroom does not automatically call for Motto, and a workshop does not automatically call for Econo. Compare the exact models that meet your room’s load, then weigh their electrical requirements and installed prices.
How Do Econo and Motto Differ?
The series names describe their position in the lineup. The individual model specifications reveal the differences that affect your purchase.
Base Models Versus the Efficiency Tier
Econo is DELLA’s base-model series; Motto shares the efficiency tier with Umbra. That makes seasonal cooling efficiency a useful starting point, but the tier alone does not establish noise, winter performance, or installation cost. The mini split series comparison provides the lineup overview; use the selected model’s specifications to finish the comparison.
Available BTU Sizes Across Both Series
Current Econo listings include 11,500, 17,000, and 23,000 BTU cooling models. Motto listings include 9,100, 12,000, 18,000, and 23,000 BTU options, with specifications varying by voltage and model. Since BTU measures cooling capacity, compare actual cooling output rather than assuming that a rounded size category represents an identical system.
SEER2 Ratings for Similar Capacity Models
The Econo models below carry 17 SEER2 ratings, while the selected Motto models carry 19 or 20 SEER2 ratings. Higher SEER2 indicates better rated seasonal cooling efficiency, but it does not make an undersized system suitable for a larger room. Within the 18,000 BTU mini split range, check the actual capacity and efficiency together.
| Comparable size group | Econo cooling capacity | Econo SEER2 | Motto cooling capacity | Motto SEER2 |
| Around 12,000 BTU | 11,500 BTU | 17 | 12,000 BTU, selected 115V model | 20 |
| Around 18,000 BTU | 17,000 BTU | 17 | 18,000 BTU | 19 |
| Around 24,000 BTU | 23,000 BTU | 17 | 23,000 BTU | 19 |
The figures above refer to the selected current listings, rather than a single efficiency rating applied across each series.
The 23,000 BTU pair offers the closest capacity match in this table. At an equal seasonal cooling load, the rating-based energy ratio is 17 ÷ 19, suggesting approximately 10.5% lower cooling electricity use for the 19-SEER2 option. This is an illustrative calculation, not a prediction of your utility bill; weather, settings, installation, and actual operation affect the result.
Published Heating Limits and Refrigerant Types
DELLA’s series overview publishes heating down to 4°F for Econo and 19°F for the Motto/Umbra tier, with R32 refrigerant for both. However, the selected Econo 17,000 BTU and Motto 12,000 BTU 115V product pages each list a climate range starting at 5°F. Those entries are not fully aligned. For winter heating, confirm the exact model’s heating operating range and output at your local design temperature before choosing; neither a series minimum nor a general climate range proves sufficient cold-weather heating capacity.
When Is DELLA Econo Worth Considering?
Econo is most appealing when its available capacity meets the room’s needs and the completed installation offers a meaningful price advantage.
Larger Rooms With Higher Cooling Loads
An open living room or insulated workshop may need more cooling capacity than a small bedroom. The DELLA Econo Series 17000 BTU 17 SEER2 Mini Split Heat Pump AC supplies 17,000 BTU of cooling and has a published coverage figure of up to 1,000 sq. ft. It makes sense when the room needs that output and a basic-efficiency system fits the budget. A smaller room does not benefit simply from more BTUs, and the coverage figure needs to be checked against insulation, ceiling height, windows, and local weather.
When a Comparable Econo Model Costs Less
The clearest price comparison is between models with the same cooling capacity. At the time of checking, the 23,000 BTU Econo was listed at $1,099.96 and the 23,000 BTU Motto at $1,249.96, a $150 equipment-price difference before checkout promotions. Econo may offer better value for a room cooled occasionally, while longer seasonal use gives efficiency more weight. Compare written installed quotes: electrical work, mounting, and line routing can change the final gap.
When Is DELLA Motto Worth Considering?
Motto brings additional choices at the smaller end of the lineup, including a 115V option for projects where that electrical configuration is appropriate.
Smaller Rooms With Lower Cooling Loads
A compact bedroom or home office may need less cooling than Econo’s smallest listed 11,500 BTU model provides. Motto includes a 9,100 BTU option, giving you a smaller-capacity candidate to evaluate. Start with the room’s measurements, windows, and insulation using the mini split sizing calculator, then confirm the load before ordering. Even 9,100 BTU may be excessive for a very small, well-insulated room.
Rooms Needing a 115V Mini Split
For a home office used throughout the summer, cooling efficiency matters alongside electrical requirements. The DELLA Motto Series 12000 BTU 20 SEER2 Mini Split Heat Pump AC combines a 115V supply with 20 SEER2 efficiency and published coverage of up to 550 sq. ft. It is worth considering when the room needs around 12,000 BTU of cooling and the electrical plan suits that model. The voltage rating alone does not make an existing outlet or shared household circuit suitable.
What Installation Requirements Should You Compare?
Have the installer review both exact model numbers against the proposed location. A lower equipment price can lose its advantage if the installation needs additional work.
Voltage, Circuit Capacity, and Electrical Work
The selected Econo 17,000 BTU model requires 208–230V, while the selected Motto 12,000 BTU model requires 115V. Both product pages list a 20A maximum fuse size, but that figure alone does not specify the complete circuit design. For either single-zone mini split system, have the electrician check the equipment nameplate, minimum circuit ampacity, permitted overcurrent protection, wiring requirements, and available panel capacity.
Line Set Length and Drainage Route
Both recommended models include a 16-foot copper line set with 1/4-inch and 3/8-inch tubing. Measure the actual route around corners and through walls rather than only the straight-line distance between units. A longer run must meet the exact model’s length, elevation, and refrigerant-charge requirements. The mini split installation steps also show why drainage belongs in the plan: confirm a suitable gravity route or an appropriate condensate-pump arrangement before deciding on the indoor location.
Mounting Clearances and Future Service Access
Choose the mounting locations before accepting the quote, and have the installer verify three practical details:
Indoor clearances meet the model’s manual, with room to open the cover and remove filters.
Outdoor airflow remains unobstructed by fences, shrubs, stored items, or expected snow accumulation.
Technicians can reach the service valves, electrical connection area, and drain components for future maintenance.
A narrow side yard or crowded workshop wall may require a different mounting position. Resolve that change before purchase so the quote includes the correct bracket or pad and revised line route.
FAQs
Which Series Is Quieter for Bedrooms?
There is no verified series-wide noise winner. The selected Motto 12,000 BTU product description advertises 27 dBA operation, while the Econo 17,000 BTU description advertises 32 dBA. Those are different-capacity systems, and the descriptions do not establish matching fan speeds or test conditions. For a bedroom, compare indoor noise at the same operating setting on correctly sized candidate models.
Can Either Series Cool Multiple Rooms?
They are single-zone systems, so multiple rooms should not be assumed to receive even cooling from one indoor unit. Connected open spaces may share airflow, but a closed bedroom has no direct air delivery from a living-room head. If both rooms need independent temperature control, evaluate separate single-zone systems or a compatible multi-zone system rather than adding capacity to one head.
Do Both Series Support App Control?
Yes. Both recommended product pages describe Della+ app control, including schedules and timers. The selected Motto page specifies 2.4 GHz Wi-Fi support. Confirm the exact model’s pairing instructions and compatible network before setup; a higher efficiency tier is not required simply to obtain app scheduling.
Do Both Series Have Warranty Coverage?
Yes. The product pages list a one-year limited warranty and an extended parts-coverage program for units registered within 100 days of purchase. The stated coverage differs according to installation status, and lifetime parts coverage does not include labor. Keep your receipt, model and serial numbers, registration confirmation, and installation records, and review the applicable shipping charges and exclusions.
Conclusion
Shortlist the exact Econo and Motto models that meet your room’s heating and cooling loads, then request an installed quote for each. Choose Econo when its suitable capacity and lower completed cost make the stronger case. Choose Motto when its available size, cooling efficiency, or 115V configuration provides value for the way you use the room. If winter heating is essential, resolve the published temperature differences with model-specific documentation before placing the order.
