10 Best Heat Pumps 2025 in the United States

The Senville LETO Series Mini Split Air Conditioner Heat Pump is a versatile choice for anyone looking to efficiently heat and cool a medium to large space, like a home or business. With a cooling capacity of 24,000 BTU and a heating function that operates down to 5°F, it offers an all-season solution. Its Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER) ratings are respectable, with a SEER of 17, making it fairly energy-efficient compared to other units. It does not comply with Energy Star standards, which could impact perceived efficiency savings.

One of the standout features is its integration with Alexa, allowing for voice control and app-based adjustments. This can provide a convenient user experience, especially for those who appreciate smart home technology. Additionally, the unit operates at a noise level of just 34 dB, making it a quiet option for bedrooms and living areas.

On the practical side, the Senville LETO comes with an installation package, which includes all essential components, though professional installation is recommended. The 5-year warranty on parts and the compressor is a plus, providing peace of mind regarding reliability. However, the unit's lack of Energy Star compliance could mean higher long-term energy costs compared to compliant models, and some users may find the need for professional installation to be a drawback, especially if they prefer DIY options.

The PIONEER Diamante Series Ductless Mini-Split Air Conditioner Inverter Heat Pump is a versatile and efficient option for residential and light commercial use. With a capacity of 12,000 BTU/hour, it effectively covers an area of up to 450 square feet. The unit boasts a high SEER rating of 20 and an HSPF of 10, which means it is energy-efficient and can help reduce your electricity bills.

Additionally, the system operates quietly at a noise level of 40 dB, making it suitable for environments where noise levels are a concern. The 16 ft. installation kit and included remote control make it convenient to set up and use. The use of a 115V power supply and the Energy Star certification further add to its appeal for energy-conscious users.

However, some potential drawbacks include the need for professional installation, which could add to the initial cost, and the fact that it's a ductless system, which may not be suitable for all types of homes. Despite these considerations, its efficiency, quiet operation, and comprehensive installation kit make it a strong contender in the heat pump category.

The MrCool Easy Pro 18k BTU ductless heat pump is designed for efficiency and ease of installation, making it a suitable option for homeowners seeking a mini-split system. With a Seasonal Energy Efficiency Ratio (SEER) of 18.5, it excels in energy efficiency, which can lead to lower energy bills. This unit is rated for spaces up to 550 square feet, making it ideal for small to medium-sized rooms. Its 60 dB noise level is generally acceptable, though it may be noticeable in very quiet environments.

One of its standout features is the 'Follow Me' capability, allowing the unit to sense the temperature where the remote is located, ensuring more personalized comfort. The added Wi-Fi compatibility also allows for convenient remote control via a smartphone app, catering to tech-savvy users. The inclusion of a 16ft pre-charged line set simplifies installation, appealing to DIY enthusiasts. Moreover, it has washable filters, which are easy to maintain.

The product does have some drawbacks. The 1-year warranty on the compressor and 2-year warranty on parts, while decent, may not provide the same level of confidence as longer warranties offered by competitors. Additionally, the noise level, while not excessively high, could be a consideration for users sensitive to sound. This heat pump uses R-410A refrigerant, which is known for being more environmentally friendly compared to older refrigerants, aligning well with modern standards. However, like any system, it requires proper installation to ensure optimal performance, which could be a barrier for some users.
