Rheem heat pumps are some of the most energy-efficient on the market today. In fact, they boast a Seasonal Energy Efficiency Ratio (SEER) of up to 20, which is significantly higher than most other brands. Additionally, their Heating Seasonal Performance Factor (HSPF) rating is also among the highest in the industry. This makes Rheem heat pumps an excellent choice for homeowners who are looking to save money on their energy bills. One of the reasons that Rheem heat pumps are so efficient is that they mostly use a two-stage compressor. This means that the pump only runs at full capacity when it is absolutely necessary – during very cold weather, for example. For more moderate temperatures, the compressor runs at a lower speed, which uses less energy. In addition to being energy-efficient, Rheem heat pumps are also very quiet. This is thanks to their unique design, which includes sound-dampening insulation. As a result, you won’t have to worry about the pump disturbing your peace and quiet.
