The Lennox XP21 Heat Pump at a Glance:

Energy Efficiency
  • Energy Efficiency: With ratings up to 19.20 SEER and 9.70 HSPF, this system can deliver hundreds of dollars in savings every year, because it is nearly twice as efficient as a standard heat pump.
  • SunSource® Solar-Ready: Reduce or eliminate the cost of heating and cooling your home by pairing your new Lennox heat pump with SunSource® solar panels. Let the sun generate the electricity you need to operate your new heat pump, and enjoy green-friendly comfort all year round.
  • iComfort Touch® Touchscreen Thermostat: The XP21 Lennox heat pump is compatible with iComfort® technology, and when installed properly by Four Seasons, this user-friendly thermostat will make controlling temperatures and maximizing savings easier than you ever thought possible.
  • Most Efficient ENERGY STAR® Qualified: Every year, the EPA recognizes HVAC systems that go above and beyond their standards for energy efficiency, and the XP21 heat pump was named in 2012 as one of the Most Efficient ENERGY STAR® qualified systems.
  • Dual-Fuel Capability: With this Chicago climate, many people pair their Lennox heat pump with a traditional heating and cooling system. The mild days are spent relying on the heat pump for heating and cooling, and the furnace and air conditioner are only used on exceptionally hot or cold days. This saves the homeowner significant amounts of money on their energy bills by using the most efficient system possible for the weather conditions.
  • High-Efficiency Outdoor Coil: This coil was specially designed to decrease air resistance and allow for easy heat transfer. The result is extraordinary comfort and energy efficiency.

Quiet Operation
  • Sound Levels: Excessive operational noise can seriously impact the peace in your home. The XP21 protects you from disruptions in comfort by putting many innovative sound dampening technologies in place to achieve sound levels as low as 67db!
  • SilentComfort™ Fan Grille: This patent-pending fan grille uses Lennox's vortex-suppression technology to minimize the noise created by airflow out of the unit. This helps keep sound levels low on even the most demanding days.
  • Compressor Sound Cover: The cover for the XP21 Lennox heat pump is not only sleek and attractive, it is also functional! Precision molding allows this compressor cover to help minimize sound levels.
  • Insulated Compressor Compartment: The XP21 takes noise control a step further by installing vibration-isolating mounts and by lining the compressor compartment with special materials to dampen any noise that may be generated by normal operation.

Home Comfort
  • Silent Comfort™ Enabled Two-Stage Scroll Compressor: This compressor keeps your home comfortable without wasting energy. The two-stage design allows the unit to operate in the lower stage 80% of the time while maintaining the ability to kick up the power when the weather demands higher output.
  • Humiditrol®: The less moisture there is in the air, the easier it will be for your heat pump to keep your home cool. Have Four Seasons install our whole house dehumidification system, and enjoy a more comfortable home and enhanced indoor air quality!

  • SilentComfort™ Outdoor Fan Motor with Composite Fan Blades: No matter the weather, the outdoor fan motor in your XP21 Lennox Heat Pump will start on-demand time and time again. This reliable component also prevents debris and ice from interfering with performance. By automatically increasing starting torque, the fan will burst through obstructions that may stand in the way of total home comfort.
  • PermaGuard™ Cabinet: Rust and corrosion are often the reason why standard heat pumps cannot withstand the test of time. This Lennox heat pump is equipped with a PermaGuard™ cabinet to deliver long-term protection against damage.
  • SmartHinge™ Louver Design: This feature allows the heat pump's cabinet to open effortlessly allowing for quick, easy access to all major components within the system. This makes it easy for your Four Seasons technician to clean the system thoroughly and efficiently.
  • Four Seasons Warranty Coverage: Four Seasons Heating, Air Conditioning, and Plumbing is the largest dealer of cooling and heating systems in Chicago. Because of this fact, we are able to offer some of the best warranties in the industry!
