Best 12000 BTU Mini Split

Mini Splits are rapidly growing in popularity as they’re energy-efficient, cost-effective, and have versatile installation options. They offer better temperature control as every indoor unit works independently to set different temperatures for the rooms in your home without maintaining uniformity in the entire space.

With this zone cooling, you can decrease your household’s energy usage, as you’ll only need to cool the parts of your home that you need.

However, it’s important to match your mini-split air conditioners’ size with the size of your room. Fortunately, a 12,000 BTU will give you enough power for small and spaces around your home.

When buying mini-split air conditioning systems, units with 12K BTUs are considered the most ideal because they are powerful, energy-efficient, and affordable compared to others.

While units below 12000 BTUs are energy-efficient, they might not be powerful enough for your room, depending on the square foot, insulation, ceiling height, and climate. On the other hand, units above 12000 BTUs tend to be less efficient but powerful enough for larger rooms.

Benefits of 12000 BTU Mini-split system

Energy Efficiency

A mini-split is among the most energy-efficient ways to heat and cool your home. Reputable 12K BTU mini splits are energy certified and can save you 20-60% on your household heating bills. Unlike the central air conditioning systems that tend to leak, these mini splits are efficient as they don’t let any energy go to waste. 

Easier Control

Unlike central conditioners that heat or cool the air around your entire house, 12K BTU mini-split systems allow you to limit the temperature in one room and set a different temperature on another. Even better, most modern 12K mini splits come with wireless controllers to allow you to set the temperature you like. 

Room Size

When buying a mini-split air conditioner, the size of your room will highly influence the unit you choose. However, not many people are sure of their room size, which might lead to purchasing an underpowered unit.

Fortunately, a 12K BTU mini-split system will work well with most medium and large rooms around your home. However, it’s important to note your room’s insulation and the number of zones you’re planning to cool. 

How Many Square Feet Will A 12000 BTU Mini Split Cool?

The higher the BTU, the more power that a ductless air conditioning unit can deliver. As such, a 12000BTU mini-split heater and air conditioner will be perfect for any room between 350 to 500 square feet. However, you consider adding a 20% BTU if your house has poor insulation and 30% if you live in areas with over 90 degrees Fahrenheit temperatures.

How Much Will It Cost To Run A 12000 BTU Mini Split?

The cost of running your ductless mini split conditioner will depend on the brand you buy and your room’s requirements. However, you can reduce the operation costs by buying an air conditioner with a high SEER rating and reducing the number of hours you use it daily. Nonetheless, you can expect to pay about $0.16 per hour, even with the best 12000 BTU mini-split. 

How Many Watts Is A 12000 BTU Mini Split?

There are around three power levels with a 12000 BTU mini-split, including 1200 watts, 800 watts, and 400 watts. However, you’ll need all the power to stay comfortable during sweltering days. Fortunately, you can run the system continuously. 

Things To Consider When Choosing A Mini-Split System

Number of Zones

Before buying a mini-split, consider the zones in your hose that you need to cool or heat. Although most mini splits only have a single indoor unit, only servicing one area like a living room or the bedroom, you can get a unit that services multiple zones. With multi-zone mini split conditioners, you get several indoor units connected to a single outdoor compressor. Fortunately, each indoor unit comes with an independent thermostat to personalize your rooms’ temperature based on your preference. 

Energy Efficiency

An efficient way to remain comfortable with being energy efficient is by choosing a mini-split with an inbuilt heat pump. Instead of using large amounts of electricity to keep you warm, the built-in heat pump takes warm air from outside and transfers it to your home. The process uses very little electricity and thereby very economical.  

Temperature Range

While a 12000K BTU mini-split unit can work in different areas, your locality’s temperature is a huge consideration when buying an air conditioner. Whether you want to heat or cool your home, you’ll want a system that makes use of ambient heating and cooling that works despite scorching hot or frigid temperatures without breaking down the compressor. 

Noise Levels

With the compressor located outside the house, most 120000 BTU mini splits can operate quietly without interrupting your sleep, studies, and other activities. However, you’ll need to consider those close to the compressor as they’ll be the ones most affected by any noise it creates. However, you shouldn’t have noise issues with units running at 45 dB or lower.  

Installation

The best 12000 BTU mini-split comes with an installation kit, making the set up easy. That typically includes electrical wiring, copper wires, draining tubes, and wall sleeves, though that may vary depending on the brand. However, most units require a professional to install, although they might be advertised as DIY friendly. 

Conclusion

Whether you’re in the height of summer or the plight of winter, a 12000 BTU mini-split is the perfect multi-purpose unit to stay comfortable all year long.

These ductless systems work great for medium and small spaces while being energy efficient to save you money on electricity costs. Feel free to buy any of the seven best 12000 BTU mini-splits above.
