10 Best 110 Volt Air Conditioner 2025 in the United States

The Dreo Portable Air Conditioner offers an 8000 BTU cooling capacity (5000 BTU DOE), making it a good fit for small to medium bedrooms or rooms up to about 150 square feet. It uses an efficient R-32 refrigerant and has a SEER rating of 6.1, which balances cooling performance with reasonable energy use. Noise is kept low at 45 dB thanks to Dreo's patented noise isolation system, so it’s quiet enough for sleeping or working. A big plus is the drainage-free cooling system that automatically evaporates excess water, so you don’t have to worry about emptying a water tank, which is ideal for humid environments.

The unit’s smart features are user-friendly, allowing control via an app or voice assistants like Alexa and Google Home, and it even includes a sleep mode to customize comfort overnight. Installation is straightforward with included window kits and caster wheels make it easy to move between rooms. However, its 8000 BTU cooling power may be underpowered for larger rooms or very hot climates, and the unit weighs 55 pounds, which might be a bit heavy for some to move frequently.

While its energy efficiency is decent, there are more efficient models available if electricity cost is a major concern. This AC is well suited for users who want a quiet, smart, and low-maintenance portable air conditioner for small spaces.

The LG LW1224RD is a 12,000 BTU window air conditioner designed to cool rooms up to 550 square feet, making it a solid choice for medium to larger living spaces like bedrooms, living rooms, or open areas. It operates quietly at about 53 decibels on low, which means it won’t be disruptive in most home or office environments. The unit offers three cooling and fan speeds, plus an Auto Cool mode, so you can easily adjust airflow to your comfort. Its energy efficiency ratio (EER) is 11.4, which is decent for this size and should help moderate electricity use, though it doesn’t have a formal energy star rating. It runs on standard 115 volts, making it compatible with typical household outlets.

Installation involves fitting it into a window, and the dimensions are fairly standard but somewhat bulky (about 22 x 24 x 15 inches), so you'll need to ensure your window can accommodate it. Additional convenient features include electronic controls with a remote for easy adjustments and an Auto Restart function that turns the unit back on after a power outage, which adds comfort without hassle. The built-in dehumidifier also helps reduce moisture in the air, which can improve overall comfort. The downside is that it weighs 82 pounds, so installation might require some assistance. Also, the one-year limited warranty is fairly standard but not especially generous.

The product has strong customer satisfaction with a 4.2-star rating from over 16,000 reviews, reflecting reliability and performance that most users appreciate. This LG air conditioner is a good pick for those needing efficient cooling in a larger room with quiet operation and user-friendly controls, though its size and weight should be considered when planning installation.
