DID YOU KNOW?
SEER Rating
SEER stands for the seasonal energy efficiency ratio, which is calculated by the cooling output during a typical cool season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is.
iComfort®-Enabled Technology**
When installed with the easy-to-use programmable iComfort Wi-Fi® thermostat, your furnace can make adjustments as needed to optimize performance and efficiency. The iComfort®? compatibility also gives homeowners the opportunity to integrate with the iHarmony®? zoning system to control the temperature in different areas of your home, PureAir™ air purification unit to remove allergens and germs from your air and Humiditrol® dehumidification unit to complete your home comfort system.
iHarmony® Zoning System
Set each area in the house to exactly the temperature you like with the iHarmony® zoning system. You can adjust every zone with your main thermostat or through a web-enabled device based on heating and cooling needs throughout the house.
* Based on Iowa. This chart compares the 5-year savings you can expect from a 26.00 and 21.20 air conditioner vs. existing equipment with a 10.00 SEER rating and industry-standard equipment with a 13.00 SEER rating. The region used to calculate household fuel and utility costs reflect a cross-section of cities in the U.S. In addition to geography, cooling costs are based on 3-ton capacity specifications, with 1,800 cooling hours per year and 11.62 cents per KWh (Source: EIA National average electric rate-Rolling 12 months ending December 2012). Your actual costs will vary depending on the weather, local fuel rates, system settings and your personal lifestyle. Savings chart shows the 5-year savings you can expect from an 18.50 SEER heat pump vs. existing equipment with a 10.00 SEER rating. The regions used to calculate household fuel and utility costs reflect a cross-section of cities in the U.S. In addition to geography, cooling costs are based on 3-ton capacity specifications, with 1,800 cooling hours per year and 12.29 cents per KWh (Source: EIA National average residential electric rate, August 2014 YTD).
**iComfort Wi-Fi® Touchscreen thermostat must be installed with an iComfort-enabled indoor unit for maximum performance.
*** Consult your tax expert before claiming energy efficiency solar tax credits.
† Efficiency claim based on comparison of air conditioning and heat pump products' SEER as published in AHRI (January 2015). Actual system combination efficient may vary; consult a Lennox Dealer or AHRI for exact system efficiencies. Precision claim based on the cooling capacity range of the XC/XP25-036 units as compared to equivalent-sized competitive variable capacity compressor units.
† † Must be accompanied by either a variable speed air handler or furnace and the ComfortSense® 7000 Series touchscreen thermostat. Sound Rating Number according to ANSI/AHRI Standard 270-2008. "SRN" is the overall A-Weighted Sound Power Level, (LWA), dB (100Hz to 10,000Hz). Sound information based on 3 ton models. Standard system is a 13ACX with a 76 dB sound rating.
