Lennox XC20 Efficiency Ratings
- Efficiency ratings as high as 20.0 SEER (Seasonal Energy Efficiency Ratio)
All new air conditioners installed in Arizona are required by the U.S. Department of Energy to be at least 14-SEER. New AC units 16-SEER and above are considered very efficient, 18- and above ultra-efficient, and 20-SEER and above extremely-efficient. In other words, while Lennox may only classify this as one of their “better” units, it actually competes with some of their competitors best.
If you were replacing an older 10-SEER unit with the XC20, you can expect to see an approximate 50% savings on your cooling cost! That said, at Magic Touch Mechanical we often advise our clients not to buy a new air conditioner based on efficiency alone. An air conditioners job is to keep our home comfortable, and the XC20’s design and components do just that, with it’s variable speed compressor discussed in the next paragraph.
The Lennox XC20 AC unit has earned Energy Star’s “Most Efficient” designation (compared to competitor brands).
