10 Best Quiet Air Conditioners 2025 in the United States

The Midea 12,000 BTU Smart Inverter Air Conditioner is designed for medium to large rooms up to 550 square feet, offering strong cooling power combined with useful heating and dehumidifying features for year-round comfort. It stands out with its energy efficiency, holding an Energy Star rating and using inverter technology that can save up to 35% on electricity compared to standard models. The unit includes multiple fan speeds and five operating modes (cool, heat, dry, fan, auto), which allow you to tailor its performance to your needs.

A programmable 24-hour timer and remote control, along with smart home compatibility (via app and voice assistants like Alexa and Google), add convenience and flexibility. Noise-wise, it operates quietly enough to not disturb daily activities or sleep, with a noise level around 45 dB in low settings, although the specs mention 58 dB which is still reasonable for a window unit. One limitation is that the heat function won't work in very cold outdoor temperatures below 41°F, so it’s more suited for mild heating needs. Installation fits double-hung windows with specific size requirements, which is common for this product type. Its washable filter and electronic controls make maintenance and use straightforward.

This air conditioner is a strong option for those seeking a quiet, energy-efficient unit that also offers heating and smart control features, particularly suitable for moderate climates.

The Midea MAW08HV1CWT EasyCool Smart Inverter Air Conditioner is a versatile unit offering both cooling and heating functions, making it suitable for year-round use. It has an 8,000 BTU capacity, which is ideal for rooms up to 350 square feet. One of its standout features is its quiet operation, with a noise level as low as 45 dB, making it a great choice for bedrooms or home offices where minimal noise is crucial.

Additionally, it boasts a high Seasonal Energy Efficiency Ratio (SEER) of 14.5, ensuring that it consumes less energy and helps save on electricity bills. The unit is Energy Star certified, indicating that it meets stringent energy efficiency guidelines. This air conditioner is also equipped with smart features, including Wi-Fi capability, allowing you to control it via a mobile app or voice commands through Alexa and Google Assistant. This adds a layer of convenience, especially with its programmable 24-hour timer and multiple fan speeds.

Installation might be a bit challenging for some as it requires a window opening of at least 14.5 inches in height. It is also relatively heavy at 56 pounds, so assistance might be needed during setup. Despite these minor drawbacks, the Midea MAW08HV1CWT offers a robust combination of quiet operation, energy efficiency, and smart features, making it a compelling option for those seeking an effective and multi-functional air conditioner.
