Rated 4.9 out of 5 by 73 reviewers.
Rated 5 out of 5 by This product is the Rolls Royce of A/C Units This is the rolls royce of A/C units. Just had it installed and used ECM who gave me a huge rebate through Lennox and also FPL. The unit has lots of great features and has huge cooling capability. My house will go from 80 degrees to 72 in about 35mins. Also this unit has cut my electric bill in half so it will basically pay for itself in a year :) Very happy with this unit and you will be to. November 13, 2012
Rated 5 out of 5 by Very quite in low speed. The unit runs very quiet in low speed and so far has not had to go to high speed. Is just slightly bigger than an old 14 seer unit that was 11 years old. Keeps the humidity to the preset level with no problem. April 29, 2013
Rated 5 out of 5 by Works great, cools quickly & quietly. The dehumidifier works quickly, reducing the energy needed to cool the house. It is very quiet, particularly in the single stage mode. I'm waiting for my first electric bill to see how efficiently it runs. April 26, 2013

*This chart compares the 5-year savings you can expect from a 21.20 SEER 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 July 2009). Your actual costs will vary depending on the weather, local fuel rates, system settings and your personal lifestyle.
