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.

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.

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.
