10 Best Quiet Air Conditioners

This EUHOMY portable air conditioner is a solid choice if you need a quiet, energy-efficient unit for small rooms up to about 215 sq.ft (20㎡). It offers a decent 9000 BTU cooling capacity, suitable for bedrooms or small offices but not large spaces. Noise-wise, it runs at a low 49 dB, making it quiet enough to keep running without disturbing your sleep or work. The energy efficiency is good with a 3-star rating and an eco-friendly R290 refrigerant, helping to reduce electricity bills and environmental impact. Its 4-in-1 design means it not only cools but also dehumidifies and offers fan and sleep modes, which adds flexibility for year-round use. You get 2 fan speeds to adjust airflow, which is basic but sufficient for most needs.

Installation is straightforward since it comes with a window kit that fits various window types and the unit has wheels and handles for easy movement between rooms. The digital display and remote control make it user-friendly, and safety features like a child lock add peace of mind. On the downside, it is a bit heavy at over 22 kg, so moving it might require some effort despite the casters. Also, the 3-star energy rating is moderate—there are more efficient models if energy savings are your top priority. The cooling capacity might be limiting if you have a larger room or want faster cooling in very hot climates.

This portable AC is well-suited for users needing quiet, versatile cooling in smaller spaces with easy installation and decent energy efficiency, but it’s not ideal for larger areas or those wanting premium energy savings.

The Meaco MeacoCool Pro Series 12,000 CH is a portable air conditioner designed for rooms about 18 to 28 square meters. It offers a solid cooling capacity of 12,000 BTU, suitable for living rooms, bedrooms, or offices. One of its standout features is the low noise level, operating around 52 dB, making it quieter than many portable units. This quiet operation is enhanced by a Sleep Mode that further reduces noise and dims the display lights, helping maintain a peaceful environment while sleeping. Energy efficiency is another strong point, with an A-class energy rating and the use of the environmentally friendly R290 refrigerant, which helps keep electricity costs relatively low compared to less efficient models.

The unit is versatile, functioning both as an air conditioner and heater, and includes modes for drying and fan-only use. It’s portable, equipped with wheels and a flexible window kit for easy setup in various window types, making it convenient to move between rooms. Control options include a remote and Wi-Fi connectivity via the Meaco App for adjusting settings remotely.

On the downside, the unit is somewhat bulky and heavy at 30 kg, which might make moving it less easy for some people despite the wheels. Also, while 52 dB is quiet for a portable AC, it may still be noticeable in very quiet spaces. Installation requires a window, so it’s not suitable for all room types or setups. This model represents a well-rounded choice for those seeking a quieter, energy-efficient portable air conditioner with added heating and smart control features, best suited for medium-sized rooms with a suitable window for installation.

The Pro Breeze 4-in-1 Smart Portable Air Conditioner offers a mix of convenience and functionality that suits a variety of spaces, from small to large rooms. With a cooling capacity of 5000 BTU, it’s particularly effective for those needing moderate cooling power. Its noise level, at 52.3 dB, is reasonably quiet for a portable unit, making it a good fit for quieter spaces like bedrooms and home offices. Featuring a 5-star energy rating and an energy efficiency of A, it promises economical operation.

The inclusion of WiFi capability and compatibility with Alexa and Google Home provides modern control options, allowing for remote operation and voice commands. This feature is particularly helpful for tech-savvy users who appreciate smart home integrations. Installation is straightforward as it comes with two window venting kits, making it adaptable to different window types.

The air conditioner’s multifunctionality is also a highlight, with four modes including cooling, dehumidifying, fan-only, and energy-saving sleep mode, enhancing its versatility for different climate needs. However, its cooling power of 5000 BTU may not be sufficient for larger or poorly insulated areas during extreme heatwaves. The unit’s size and weight (18 kg) could also pose a challenge when moving it between rooms. Additionally, the water capacity is limited to 500 millilitres, potentially requiring frequent emptying in humid environments.
