10 Best Air Conditioners 2026 in the United States

The Goodman 3 Ton 14.5 SEER2 air conditioner paired with the multi-positional air handler offers solid cooling performance suitable for homes around 2100 square feet. With a cooling capacity of 36,000 BTUs (3 tons), it can comfortably cool medium to larger rooms. The SEER rating of 14.5 means it is reasonably energy efficient, although not the highest available on the market, so expect moderate electricity use. At 67 decibels, the noise level is about average — you’ll hear it running, but it shouldn’t be overly disruptive.

This split system uses the newer, eco-friendlier R-32 refrigerant and comes with a 10-year parts warranty when professionally installed and registered, adding peace of mind. The included air handler is versatile, supporting different installation positions (upflow, horizontal right or left), which is helpful if your home’s ductwork is tricky. However, this system only cools and does not provide heating, so if you want heat, you’ll need extra equipment like a heat pump or a separate heat kit. Also, accessories like thermostats and outdoor sensors are sold separately.

It is a dependable choice if you want straightforward, efficient cooling and are okay with adding heating solutions on your own. While not the quietest or the most energy-saving model, it delivers reliable performance backed by a good warranty.

The Dreo Portable Air Conditioner offers a solid cooling capacity of 10,000 BTU, suitable for rooms up to about 200 square feet, like bedrooms or small living spaces. It uses an innovative IceCool system combined with a fan to cool quickly and lets you adjust the temperature between 61°F and 86°F to your liking. One standout feature is its quiet operation at just 45 decibels, which is gentle enough not to disturb sleep or work. It also has a smart drainage-free system that automatically evaporates excess water, so you don’t need to worry about emptying a water tank in most environments.

The unit is easy to move around on caster wheels, and it comes with modular window panels and an exhaust hose for flexible installation on different window types. You can control it via a remote, app, or voice assistants like Alexa and Google Home, adding convenience and customization, including a sleep mode that adapts cooling based on your preferences. Its Energy Efficiency Ratio (SEER 6.51) is average for portable units, meaning it may consume more electricity than some other models, so energy-conscious users might want to consider this.

The unit is a bit bulky and weighs over 57 pounds, which is typical for its class but something to keep in mind if you plan frequent moves. Customer feedback highlights its effective cooling and quietness, supported by 24-hour customer support and a 1-year warranty. This Dreo model is a strong choice if you want a portable AC with smart features and low noise, best suited for medium-sized rooms and users who value convenience and quiet performance more than ultra-high energy savings.

The Midea MAW12V1QWT U-Shaped Window Air Conditioner offers efficient cooling with smart features, delivering 12,000 BTUs suitable for rooms around 550 square feet, making it ideal for medium-sized living spaces. Its standout feature is the very quiet operation at just 32 dB, which is significantly quieter than many traditional window units. This is achieved through its innovative U-shaped design that fits into the window while blocking outside noise. This design also allows you to keep your window partially open for fresh air and a better view.

This unit uses environmentally friendly R-32 refrigerant and is energy efficient, boasting a high SEER rating of 15 and a 5-star BEE rating. These features help reduce electricity bills by over 35% compared to older models. Additionally, smart connectivity allows control via a smartphone app or voice commands through Alexa and Google Assistant, adding convenience for smart home users. Installation is straightforward with the included bracket, fitting most standard windows, and the unit includes helpful features such as a dehumidifier, dust filter, and fast cooling mode.

While the noise level is low, the unit weighs nearly 59 pounds, so installation might require assistance. It requires a standard 115V power source and comes with a remote control with batteries included. This air conditioner is an excellent choice for those seeking a quiet, energy-saving, and smart-controlled cooling option for a medium-sized room, featuring a modern design that allows for a more open window than usual.
