Choosing the right mini split involves more than finding the correct BTU capacity.
Your climate, heating needs, efficiency priorities and budget can all influence which system makes the most sense for your home. That’s why Senville offers different mini-split series designed around different comfort needs.
Three of the main options are the Leto, Aura and Elite Series.
While all three provide heating and cooling, they aren’t designed with exactly the same priorities in mind. LETO offers practical everyday comfort and value, AURA is built with cold-climate performance in mind, and Elite adds an even greater focus on advanced energy efficiency.
Here’s how they compare.

1. Start With What Matters Most for Your Home
There isn’t one Senville series that is automatically the right choice for every homeowner.
Before comparing individual systems, think about what matters most for your space.
Are you looking for:
- A practical heating and cooling solution at a more accessible price point?
- Stronger performance during very cold Canadian winters?
- Higher efficiency as a major priority?
- A system you expect to rely on heavily for heating?
- A particular BTU capacity or configuration?
Answering those questions first makes it much easier to narrow down the options.
QUICK ANSWER
Leto is a practical choice for everyday heating and cooling, Aura is designed with stronger cold-climate performance in mind, and Elite combines cold-climate capability with an additional focus on advanced efficiency.
The right choice depends on your home, climate and comfort priorities.
2. Is the Senville Leto Series Right for You?
The Leto Series is a good place to start for homeowners looking for a straightforward mini split solution for heating and cooling.
It offers inverter-driven operation and is designed to provide year-round comfort without necessarily focusing on the extreme low-temperature performance of a cold-climate system.
Applicable Leto models can operate in heating down to approximately -15°C (5°F).
That can make Leto a good fit for spaces where:
- Budget is an important consideration
- Everyday heating and cooling are the main priorities
- Extreme cold-weather heating isn’t the primary requirement
- The mini split may supplement another heating source
- You want a simple, flexible comfort solution
LETO MAY BE RIGHT FOR YOU IF...
You want dependable everyday heating and cooling and don’t necessarily need the lowest cold-weather operating range or the highest efficiency available in the Senville lineup.
3. Is the Senville Aura Series Better for Cold Canadian Winters?
For homeowners who expect to rely more heavily on their mini split during a Canadian winter, the Aura Series is designed with cold-climate operation in mind.
Applicable Aura models can provide heating operation down to -30°C (-22°F).
The series uses features designed to support operation in colder conditions, including inverter technology and cold-weather components such as a base pan heater and crankcase heater on applicable systems.
It’s also the only Senville series that offers multi-zone configurations. That makes Aura especially useful for homeowners who want to heat and cool multiple rooms or areas from one outdoor unit while still prioritizing strong cold-weather performance.
AURA MAY BE RIGHT FOR YOU IF...
• Winter heating is a major priority
• You live in a colder Canadian climate
• You want to use your heat pump through more of the heating season
• You want a multi-zone system for several rooms or areas
• Low-temperature operation is more important to you than choosing the most budget-focused option
COLD CLIMATE TIP
Don’t compare heat pumps using the lowest operating temperature alone. The system still needs to be properly sized for your home’s heating load, and its heating capacity at colder temperatures also matters.
4. Is the Senville Elite Series Worth It for Higher Efficiency?
The Elite Series is also designed for cold-climate applications, but with an additional emphasis on advanced energy efficiency.
That makes it particularly interesting for homeowners who want cold-weather capability while also prioritizing higher efficiency ratings.
Depending on the specific capacity, Elite models can offer very high SEER2 ratings, with select models reaching up to 33.3 SEER2.
Select Elite models are ENERGY STAR certified.
Rather than thinking of Elite simply as “a better Aura,” it’s more useful to think about the difference in priorities:
Aura: strong cold-climate capability
Elite: cold-climate capability with an additional focus on advanced efficiency
ELITE MAY BE RIGHT FOR YOU IF...
• Energy efficiency is one of your top priorities
• You still need strong cold-weather performance
• You’re willing to compare higher-efficiency equipment rather than focusing primarily on upfront cost
• You want to explore some of the highest-efficiency ductless options in the Senville lineup

6. Which Senville Mini Split Series Should You Choose?
Each Senville series is designed with different priorities in mind. The biggest differences come down to value, cold-weather performance and energy efficiency.
Leto — Everyday Comfort & Value
Leto is a practical choice for homeowners looking for reliable heating and cooling at an accessible price point. It offers everyday comfort and heating performance down to 5°F (-15°C), making it well suited to applications where extreme cold-weather performance isn’t the main priority.
Aura — Cold-Climate Performance & Flexibility
AURA is designed for colder climates, with heating operation down to -22°F (-30°C). It’s also the Senville series that offers multi-zone configurations, making it a strong option when you want independent comfort in multiple rooms from one outdoor system.
Elite — Cold-Climate Performance & Advanced Efficiency
Elite combines cold-climate heating performance down to -22°F (-30°C) with Senville’s strongest focus on energy efficiency. Select models offer SEER2 ratings up to 33.3, making Elite a good fit for homeowners who prioritize both cold-weather performance and advanced efficiency.
7. Don't Choose Based on the Series Name Alone
Once you’ve narrowed your choice to Leto, Aura or Elite, there’s still another important decision to make:
Which capacity does your home actually need?
Mini splits are available in different BTU capacities because different spaces have different heating and cooling loads.
A larger unit isn’t automatically better.
Factors that affect sizing include:
- Square footage
- Ceiling height
- Insulation
- Windows
- Sun exposure
- Home layout
- Local climate
- Heating load
Proper sizing is important for comfort and performance regardless of which Senville series you choose.
If you’re still determining capacity, our guide on how to choose the right mini split for your home is a good place to start.
SIZING TIP
Choose the series for the features and performance you need. Choose the BTU capacity for the heating and cooling load of the space.
Those are two separate decisions.
8. Consider How Much You’ll Rely on Your Mini Split for Heating

Two homeowners with similar-sized rooms may still choose completely different systems.
For example, one homeowner may primarily want efficient summer cooling with some supplemental heating during the shoulder seasons.
Another may plan to rely heavily on the mini split throughout the Canadian winter.
That difference matters.
A cold-climate rating is valuable, but it doesn’t replace proper system selection and sizing.
9. Compare the Exact Model Before You Buy
Series-level comparisons are useful for narrowing down your choices, but individual product specifications can vary.
Before making your final decision, check the exact model and capacity for:
- SEER2
- HSPF2
- Heating operating range
- Cooling operating range
- Electrical requirements
- Indoor and outdoor unit dimensions
- ENERGY STAR certification, where applicable
- Line-set requirements
- Available indoor-unit configurations
- Warranty information
This is especially important when comparing different BTU capacities within the same series.
GOOD TO KNOW
A specification shown for one capacity doesn’t automatically apply to every model in the same series. Always use the product page and documentation for the exact system you’re considering.
