Expert Review
The XP21 offers Lennox quality with two-stage operation at a more accessible price than the XP25. The two-stage compressor spends most runtime at 70% capacity, improving efficiency and comfort. Cold climate rated to -5°F, it handles typical Nassau County winters effectively. We install these in Port Washington and Manhasset Hills where homeowners want premium performance without top-tier pricing. The Quantum coil with aluminum-alloy construction resists corrosion from Long Island's coastal humidity. IRA eligible at full $2,000.
