10 Best Mini Split Ac Cost 2026 in the United States

The COSTWAY 12,000 BTU Mini Split Air Conditioner is designed for rooms up to 750 square feet, making it a solid choice for medium-sized spaces like living rooms or offices. It offers a strong cooling capacity of 12,000 BTU and a slightly higher heating capacity at 12,300 BTU, thanks to its built-in heat pump. The unit stands out with a high energy efficiency rating of 21 SEER2, which means it can help reduce electricity bills compared to less efficient models. Noise levels are reasonably quiet at 41 decibels, roughly the sound of a quiet conversation, so it won’t be disruptive in most settings. This model supports single-zone use, meaning it’s designed to cool or heat one area rather than multiple rooms.

Installation requires a licensed HVAC professional, and the package includes everything needed for setup, including copper piping and a remote control with a child lock feature. Other convenient features include a self-cleaning function that helps keep the system hygienic, turbo mode for faster cooling, and multiple operation modes to suit different needs and seasons. The unit uses eco-friendly R-32 refrigerant, which is better for the environment than older types.

While powerful and efficient, this mini split is limited to a single zone and may require professional installation costs to consider. It operates on 208-230 volts, so it’s important to ensure compatibility with your home’s electrical system. For those seeking a reliable, energy-saving mini split with heating and cooling in one package, this COSTWAY model offers great value with solid manufacturer warranties that cover parts and compressor for several years.

Its SEER rating of 17 means it is fairly energy-efficient, which can help reduce electricity bills compared to older units. This model offers both cooling and heating, able to operate in temperatures down to 5°F (-15°C), making it useful year-round. The noise level is quite low at 34 dB, so it won’t disturb quiet environments like bedrooms or offices.

It supports a single-zone setup and includes necessary installation parts, but professional installation is required, which adds to the overall cost and complexity. A standout feature is its compatibility with Alexa and smartphone control, allowing you to adjust settings remotely or via voice commands, adding convenience. The sleek white design fits nicely in both home and commercial spaces without looking bulky.

On the downside, while it comes with a good 5-year warranty on parts and compressor, labor costs for installation are not covered. Also, it is imported from China and does not have a BEE star rating, which might be a consideration if you prioritize Indian energy certification. This mini-split AC offers a good balance of power, efficiency, and smart features for users seeking a dependable, versatile system with heating included, but be prepared for some extra installation expenses.

Additionally, the Active Clean Technology helps keep air fresh by making filter maintenance easier and protecting indoor air quality.

The BEE star energy rating is only 2 stars, meaning it may not be the most energy-efficient choice available, which could lead to higher running costs over time compared to higher-rated units. If you want a practical all-in-one heating and cooling solution with straightforward installation and quiet operation, this unit is a solid pick, especially if you're comfortable with DIY setup. However, if energy efficiency or ultra-low power bills are a priority, you might want to explore other models with higher star ratings.
