The Lennox XC13 air conditioner is part of Lennox’s Elite series, one its higher end lines. This system uses the chlorofluorocarbon-free R410A refrigerant, which Lennox says meets the strictest EPA standards. The system is also Energy Star qualified and rated for efficiency up to 15.5 SEER. Lennox claims it can save owners between $325 and $1055 per 5 years when compared to units with between 10.0 and 13.00 SEER ratings. It is equipped with a high- efficiency outdoor coil, which Lennox says provides efficient heat transfer and low air resistance. This air conditioner also has a scroll compressor that the company says provides reliable, efficient functioning.
Lennox is an excellent air conditioning system. I have rarely had problems with this brand. It is usually easy to maintain and doesn't require too much for me to keep it running for long periods of time. I have occasionally had to call in a repair man as it has stopped running a few times. But these occurrences are very few. In the past eight years I might have had to call them in two or three times. The bad part of this was handling the scorching heat without AC but the problem was usually fixed within a day or two. Otherwise the air condition keeps running for long periods of time. It makes a fan like sound on and off that my kids don't like but I think all air conditioners do that. I am immensely satisfied with this product and have recommended it to friends. If my air conditioner stopped working I would buy again from this brand.
