10 Best 24000 BTU Air Conditioning Units 2025 in the United States

The Senville LETO Series Mini Split Air Conditioner Heat Pump offers a robust 24,000 BTU capacity, making it suitable for cooling or heating spaces up to 1250 square feet. It stands out with its SEER rating of 17, indicating decent energy efficiency, although it is not Energy Star compliant. This model's low noise level of 34 dB is commendable, ensuring a quiet operation which is ideal for bedrooms or living areas. One of its significant advantages is the integration with Alexa, allowing for convenient voice control and remote operation via an app.

The unit also provides versatile functionality with its 4-in-1 capabilities: air conditioning, heating, dehumidifying, and fan modes. The inclusion of a DC Inverter enhances its efficiency and performance, and it is both UL Listed and AHRI Certified for reliability. The installation package comes with all necessary components including a 16-foot line set, which is convenient, though professional installation is required, potentially adding to the cost.

The design is both stylish and functional, fitting well into various environments from residential to commercial settings. However, the product is imported from China, which may be a consideration for some buyers. Additionally, while the warranty covers 5 years on parts and the compressor, labor is not included, which could be a disadvantage if repairs are needed. This unit is a solid choice for those needing a powerful and versatile air conditioning solution.

The GarveeHome SEER 19 24000BTU mini split air conditioner is a strong choice for cooling and heating rooms up to 1500 square feet. Its 24000 BTU capacity and 2-ton size make it suitable for medium to large rooms. With a high SEER rating of 19, it offers good energy efficiency, helping reduce electricity costs by about 30% compared to standard models. The unit runs quietly at 41 decibels, which is gentle enough for bedrooms or offices without causing distraction. Installation is designed with DIY in mind, including a kit and step-by-step guide, but professional help is recommended to fully optimize performance, especially since it requires some technical steps like vacuumizing the refrigerant line.

This split system comes with convenient smart features, such as WiFi control, a remote, programmable timer, sleep mode, and auto-restart, making it easy to customize comfort. It also uses eco-friendly R32 refrigerant and has a durable build with anti-corrosion coating. On the downside, the size and weight (over 80 pounds) might make DIY installation challenging for some, and while it includes an installation kit, full setup still needs some technical know-how.

The GarveeHome SEER 19 mini split suits users seeking a reliable, energy-saving system with modern features and quiet operation, especially those with medium to large spaces and an interest in smart home integration.

The MRCOOL 24000 BTU ductless mini split system is a strong choice for cooling and heating spaces up to about 1,050 square feet, making it suitable for homes, offices, or small commercial areas. It offers a solid cooling capacity of 24,000 BTUs (about 2 tons), which should handle medium to larger rooms comfortably. One of its biggest advantages is the easy DIY installation process with pre-charged lines and no special tools needed, saving time and installation costs. Energy efficiency is impressive with a high SEER rating of 22.7, meaning it uses electricity smartly, which can lower your utility bills over time. However, it carries only a 1-star BEE rating, which might be less relevant in the US but indicates room for improvement in energy efficiency by some standards. Noise-wise, it operates quietly at 46 decibels, so it won’t disturb your daily activities or sleep. The unit supports modern convenience with WiFi control and compatibility with Google Assistant and Alexa, allowing easy temperature adjustments from your phone or voice commands.

Additional handy features include a dehumidifier, sleep mode, and a remote control, enhancing comfort. On the downside, the unit is fairly heavy at 180 pounds and requires a 230V power supply, which might mean you need to check if your electrical setup is compatible. While the design is sleek and neutral, blending easily into most interiors, the product’s lower ranking in the broader market and the 1-star energy rating could make you consider other options if utmost energy efficiency or a lighter unit is a priority. The 5-year parts and 7-year compressor warranty give some peace of mind for long-term reliability.

This MRCOOL mini split fits well if you want a versatile, efficient, and smart-controlled air conditioner with heat for year-round comfort, especially if you value DIY installation and quiet operation.
