10 Best 110 Volt Air Conditioner 2025 in the United States

The Della Motto Series 12000 BTU mini split air conditioner is designed for spaces up to 550 sq.ft, making it a solid choice for small to medium rooms. Its cooling capacity of 12,000 BTU and heating ability with a 1-ton heat pump offer year-round comfort. It operates on a common 110-120V power supply, which is convenient for typical home electrical setups. The unit stands out with a high energy efficiency rating (20 SEER2), promising significant power savings compared to less efficient systems. Noise levels are low at 41 dB, ensuring quiet operation that won’t disrupt your daily life.

Installation requires professional help since it’s a split system with line-set vacuuming and refrigerant adjustments, so it’s not a DIY project. The package includes a full installation kit, but you’ll need to arrange professional setup. The smart features add convenience, such as WiFi and Alexa compatibility and a remote sensor that measures room temperature from the remote control for more precise comfort adjustments. Additionally, the use of the newer, eco-friendly R32 refrigerant is better for the environment than older types used in some competing models.

The unit is fairly large and weighs 63 pounds, which might need a sturdy installation spot. Also, while the system offers multiple modes and airflow directions, maximizing its benefits depends on proper professional installation and possibly sourcing additional refrigerant locally if needed. This mini split is a good pick if you want efficient, quiet heating and cooling with smart control and are ready to invest in professional setup.

The LG LW1424RD is a solid choice for cooling medium-sized rooms up to around 800 square feet. Its 14,000 BTU cooling power is quite strong, making it suitable for spaces like living rooms or large bedrooms. The unit runs on standard 115 volts and is designed for window installation, fitting most common window sizes with its compact dimensions.

It offers three fan and cooling speeds, allowing you to adjust how much cooling you want, and it includes a convenient remote control for easy operation. The energy efficiency ratio (EER) of 11.2 means it’s reasonably efficient but not among the top energy-saving models, so it won’t drastically increase your electricity bill. Noise level is about 56 decibels, which is noticeable but not overly loud—similar to a normal conversation—so it’s fairly quiet for a window AC. Additional helpful features include an auto restart function that turns the unit back on after a power outage, a washable filter with an alert to remind you when it needs cleaning, and a 24-hour timer to schedule operation.

On the downside, the product lacks any special energy star rating and the warranty is limited to one year, which might be a concern if you want longer-term peace of mind. Also, at 82 pounds, it’s relatively heavy, so installation might require some help. If you need a dependable, easy-to-use window air conditioner for a medium room without needing top-tier energy savings, this LG model offers a well-rounded mix of power, features, and quiet operation.

The LG 12,000 BTU Smart Window Air Conditioner is designed to cool rooms up to 550 square feet, making it a good choice for larger spaces like kitchens and living rooms. Its 12,000 BTU cooling power is strong enough for efficient temperature control. The unit operates on standard 115 volts and features an energy efficiency ratio (EER) of 12, which offers reasonable energy savings without being top-tier. Noise is kept relatively low, with a minimum of 52 decibels in low mode, so it won’t be too disruptive for most users. The physical size is typical for window units, and it includes an installation kit, but since it weighs 81 pounds, it might require two people to install safely.

One of its best features is smart connectivity: it works with LG ThinQ, Alexa, and Google Assistant, allowing you to control the AC remotely or with voice commands. This adds convenience, especially if you want to adjust settings without being near the unit. Additional practical features include multiple fan speeds, a 24-hour timer, auto restart after power outages, and helpful reminders to clean the filter. It comes with a one-year warranty, which is fairly standard but on the shorter side.

Though this model doesn’t have a BEE star rating and the energy efficiency is moderate, it is a solid, user-friendly option for someone who values smart home integration and reliable cooling for medium to large rooms. If you prioritize quiet operation and smart features over maximum energy efficiency, this LG air conditioner is worth considering.
