Comfort and Savings with an XC21 Air Conditioner Installation

Not all air conditioning units are created equally, and the Lennox XC21 stands out within the industry for its innovative design and highly efficient capabilities.

As one of the most popular air conditioners we install, Four Seasons Heating and Cooling is proud to offer our customers Lennox XC21 AC systems that come with:

  • Versatile Compatibility: The XC21 works with the Humiditrol® whole-home dehumidification system to keep your house comfortable in the heart of summer, and with its solar-ready design, you can save even more on your energy bills.
  • High-Efficiency Performance: Offering efficiency up to 21 SEER, you can save up to 52% on your annual cooling costs, and the XC21 has been recognized as one of the “Most Efficient ENERGY STAR in 2018” products.
  • SilentComfort™ Technology: Traditional AC systems can be loud and distracting within the home environment, but the XC21 has a sound level rating of 69dB—which is 20% quieter than a standard unit.
  • Innovative Construction: With a multi-stage design, high-efficiency coil, and composite fan blades, you can depend on your Lennox XC21 air conditioner to work efficiently and reliably on even the hottest summer days.
