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 Senville LETO Series Mini Split Air Conditioner Heat Pump offers a substantial cooling capacity of 12,000 BTU, making it suitable for cooling medium-sized rooms. One of its standout features is the high Seasonal Energy Efficiency Ratio (SEER) of 20.8, which indicates it operates efficiently and could help reduce electricity bills. The inclusion of a DC Inverter further enhances its energy efficiency and performance consistency.

This model supports voice control through Alexa, allowing for convenient adjustments via app or voice commands from anywhere, which could be appealing to tech-savvy users or those who enjoy smart home integration. Additionally, it serves multiple roles as an air conditioner, heat pump, dehumidifier, and fan, making it versatile for year-round use. The unit operates relatively quietly, which is ideal for bedrooms and living areas where noise can be disruptive.

It does require professional installation, which might add to the initial cost. Although it comes with a comprehensive 5-year warranty on parts and the compressor, labor costs for installation are not covered. The product does not meet Energy Star compliance, which might be a consideration for eco-conscious buyers. Its compact and stylish design allows it to blend into both residential and commercial settings without compromising aesthetics. The package includes necessary installation components, making it convenient, but the pre-loaded refrigerant accommodates only up to 25 ft, which could limit installation flexibility in larger spaces.

The Goodman 3.5 Ton 15.2 SEER2 Heat Pump System is designed as a solid choice for homeowners needing reliable heating and cooling with moderate energy efficiency. With a cooling capacity of 42,000 BTU (3.5 tons), it can comfortably manage the temperature in a medium to large-sized home. The SEER rating of 15.2 means it meets current efficiency standards and should help keep energy bills reasonable, although there are more efficient models available if maximum savings are a priority. The system uses R-32 refrigerant, which is better for the environment compared to older types. Noise level is around 72 decibels—noticeable but not overly disruptive, similar to the sound of a loud conversation.

This is a split system, combining a heat pump and a multi-positional air handler, meaning it can be installed in different configurations to fit various home layouts. The air handler’s corrosion-resistant design and 9-speed blower motor support reliable and flexible operation. Additional perks include an air purification filter to improve indoor air quality and a 10-year parts warranty when professionally installed and registered, providing peace of mind.

If you live in a colder climate, it's important to note that a heat kit must be purchased separately for effective heating. Installation might require extra accessories depending on your setup, such as a downflow kit. While this Goodman system is not the quietest or most energy-efficient option on the market, it delivers solid performance with a good balance of features, making it a practical option for many homeowners seeking dependable year-round comfort.
