Best Heat Pump Highlights
The Lennox SL22KLV is the best whole-home heat pump thanks to:
- A high SEER2 efficiency rating up to 21.1, perfect for Suffolk County’s often harsh climate. The SL22KLV is an Energy Star® Qualified unit.
- Use of R-454B refrigerant, compliant with new regulations set in 2025.
- Designed for efficiency in cold weather, and awarded Energy Star® Most Efficient Cold Climate 2025.
- Variable heating and cooling power that allows finer compressor operation to consistently heat or cool a home with minimal temperature fluctuations.
- Extremely quiet in operation, with noise levels as low as 58dB (quieter than a regular conversation).
What Makes the Lennox SL22KLV More Efficient?
The unique inverter technology in the Lennox SL22KLV makes it more efficient than comparably priced systems from other brands. This model can adjust the compressor in 1% power increments. This fine level of control eliminates waste and allows extremely accurate maintenance of the temperature set on the thermostat.
Lennox is one of a few premium heating and cooling brands that design unique technologies. This gives it more flexibility to innovate compared to more affordable options. Yes, Lennox units are priced higher than some alternatives, but this pays off with enhanced efficiency, better warranty coverage, and enhanced reliability.
The savings generated by a Lennox heat pump installation can help to reduce the real cost of the upfront investment.
What Type of Home is Best Suited to the Lennox SL22KLV Heat Pump?
The SL22KLV is a flagship-grade heat pump that is best suited to homeowners looking for a premium heating and cooling solution with best-in-class reliability and efficiency.
- Its dehumidification performance outclasses many similar products. It can operate efficiently at temperatures down to -20°F, so it’s perfectly compatible with Long Island’s winter.
- The system uses an Electronic Refrigerant Injection (ERI) system to adjust flow based on the outdoor temperature. In winter, ERI increases heating output to provide warmth and comfort comparable to a gas furnace.
- Uniquely important to Long Island, this model integrates a custom aluminum alloy in the coil, designed to resist salt-air corrosion.
