Lennox Precise Comfort

Lennox - XC25 - Happy Family PhotoEvery so often, a product comes along that causes an entire industry to change its thinking. An air conditioner that redefines comfort and efficiency. In the world of air conditioning, the XC25 has done just that. Thanks to revolutionary Pricise Comfort technology, the XC25 maintains a consistent temperature by making tiny, ongoing adjustments to its output throughout the day.

Exacting precision is also what makes the XC25 the most efficient air conditioner. It has an industry-high SEER (Seasonal Energy Efficiency Ratio) rating of up to 26.00. For savings year-round, the XC25 can be combined with SunSource solar modules. These allow you to use energy from the sun to reduce your cooling and heating bills by up to half. On top of all this, it offers the lowest operating noise levels of any air conditioner available. It’s simply the most advanced, most capable air conditioner ever created.

Variable-capacity cooling

The key to the XC25’s precision lies in the variable capacity of the inverter-driven compressor. Because the XC25 is installed with the iComfort Wi-Fi thermostat, the compressor can adjust output to any level between 35% and 100% in increments of 1%. The XC25 only uses the exact amount of energy you need to stay comfortable. It can accomplish this while maintaining your desired temperature with exacting precision.

Virtually Silent

Exclusive SilentComfort technology makes the XC25 up to 50% quieter than a standard air conditioner. An industry-exclusive composite fan designed with variable-speed operation and an insulated compressor compartment also help reduce sound levels.

Lennox - XC25 - SEER rating comparision chart.pdfSEERiously efficient

With industry-leading efficiencies of up to 26.00 SEER, the XC25 can save you hundreds of dollars each year on your utility bills, compared to older or conventional air conditioners. SEER stands for “Seasonal Energy Efficiency Ratio” and is a measure of a central air conditioner’s efficiency and performance. The higher the SEER, the greater your energy savings. Typical SEER ratings range from 13 to 18, but the XC25 carries ratings as high as 26.00.

True comfort is Precise Comfort

Comfort is about more than just temperature. It’s about consistency – the ability to maintain an ideal temperature and perfect humidity under any conditions. Lennox Precise Comfort technology, enabled by the iComfort Wi-Fi thermostat. Allowing your cooling system to maintain your set temperature regardless of outside conditions by making minute adjustments to airflow and cooling. So, unlike conventional cooling systems, your air stays consistently comfortable, to within 0.5 degree of your set temperature, without any hot and cold swings.

Working with a matching variable-speed air handler, the XC25 removes about 30% more humidity from the air than a conventional single-stage unit. It has the capability to remove a moisture volume that’s equivalent to 24 sixteen-ounce water bottles.
