How we built this shortlist
We prioritized units with high energy efficiency ratings, focusing on SEER2 values and BTU capacity. Products that did not meet a minimum SEER2 rating of 17 were excluded.
What we ruled out and why
Units lacking essential features and low feedback ratings were removed from our list. Any mini split not providing significant heating or cooling capacity was also excluded.
What we did not do
None of the products were tested by hand, and no lab measurements were taken. We did not create scores or rankings based on personal experience.
How often this page is updated
This page is updated regularly. We check for new models and changes in specifications every three months to ensure accuracy.
How to Choose Mini Splits
Understand BTU Ratings
BTU (British Thermal Unit) tells you how much cooling or heating power a mini split has. Choose a unit with enough BTUs for your space. For example, 12,000 BTUs can cool or heat up to 750 square feet. Larger areas need more BTUs.
Look for SEER Ratings
SEER (Seasonal Energy Efficiency Ratio) measures energy efficiency. A higher SEER rating means more efficient energy use. Look for a SEER rating of at least 17 for good savings. Units with higher ratings will reduce your electricity bills.
Check Modes Available
Different modes like cooling, heating, dehumidifying, and fan settings provide flexibility. Ensure the mini split you choose includes all the modes you need for year-round comfort. Some also have eco modes for energy savings.
Size of the Indoor Unit
Consider the size of the indoor unit if you have limited space. Complicated installations or larger models may not fit well. Smaller, compact designs are easier to place in tight areas.
Installation Requirements
Installation can vary by model. Some mini splits require professional help, while others allow DIY setups. Check the installation guidelines to ensure it fits your capabilities and budget.
What to look for
Energy Efficiency
Energy efficiency is key for mini splits. Look for units with high SEER ratings. Higher ratings mean less energy used for heating or cooling. This can lead to lower utility bills over time. Energy-efficient models often pay for themselves in savings.
Cooling Capacity
Cooling capacity is measured in BTUs. Each mini split offers different BTU ratings. More BTUs mean more cooling power. Choose a unit that matches your space size to ensure comfort. A unit that’s too small will struggle to cool effectively.
Heating Performance
Some mini splits also provide heating. Look for systems that can heat reliably in cold temperatures. Many units can heat down to -4°F. This is important in areas with cold winters. Check the BTU ratings for heating to ensure adequate performance.
Noise Levels
Noise levels can be a concern with mini splits. Some models operate quietly, while others can be loud. Check the decibel ratings for quieter operation. This can be especially important in bedrooms or study areas.
Smart Features
Smart features can enhance comfort. Some mini splits offer Wi-Fi controls or app management. This lets you adjust settings remotely. Voice control options can also be helpful. Consider what smart features might improve your experience.
Frequently asked questions
What is the cheapest mini split?
The cheapest mini split can vary based on features and brand. However, options like the Rellytech 11500 BTU Mini Split are often more budget-friendly while still offering solid performance.
How do I know how many BTUs I need?
To know your BTU needs, measure the room size in square feet. A rule of thumb is about 20 BTUs per square foot of space. Adjust based on factors like sunlight and room insulation.
Can a mini split heat and cool?
Most mini splits can both heat and cool. Look for models that mention this feature clearly. They switch between heating during winter and cooling during summer.
Is installation difficult for mini splits?
Installation difficulty can vary. Some units need professional installation, while others are more DIY-friendly. Check the installation guidelines before purchasing.
How energy efficient are mini splits?
Mini splits can be very energy efficient. Look for units with high SEER ratings. Higher ratings indicate better energy use, which can lower your utility bills.
