Read more about LENNOX Central Air Conditioners
The Lennox XC21 air conditioner is part of the Dave Lennox Signature Collection. It is Energy Star qualified and bears the Good Housekeeping seal of approval. It is rated for up to 20.5 SEER, which the Lennox company says can save up to $1500 in utility bills in five years when compared to a 10.0 SEER air conditioning unit. Buyers of the XC21 may qualify for a federal tax credit. The unit is equipped with a low-sound fan and a two-stage scroll compressor, which Lennox says is on a low setting the majority of the time, reducing power usage.

"Great System"
I love how quiet my new a/c system is. My old Trane system was so noisy that I couldn't even sit on my back porch when it was running. Not to mention my electric bills are half of what they were before. Great system, and I can't wait to replace my main level system.

"Intelligent does not apply to designers of this"
Bought communicating furnace/AC/thermostat combo. Very efficient stuff, but... Thermostat display panel throws off enough heat to throw off a/c temperature-over cools by 3-4 degrees @70 degree setting. Solution is to shutoff display and have it only on when you touch it! You think they would know enough to move the temperature sensor away from the lightbulb! Unit lasted through one cooling season without breaking. Start of second cooling season-did not cool. "Intelligent" circuitry did not give any error messages--unit just thinks its running. Since warantee not cover labor, rang up $450 to replace outdoor fan motor. So far not know long run reliability, but starting off pretty poorly.

"Super Silent Air Conditioner!"
I am very happy with my central air conditioner. My central air conditioner is the Dave Lennox XC21 air conditioner. I bought this air conditioner about 6 months ago, after my old one broke down. I was worried that it wouldn't get fixed, but then I found the XC21 air conditioner, and I bought that spontaneously. I am extremely happy with its performance thus far. I like that this is a very quiet air conditioner. I barely know it is there. It is a very nice finish too. I dislike that this air conditioner costed so much money, but I guess, in the end, it will be worth it. I have not had to repair my air conditioner or replace it thus far. I hope I never will have to either. I would recommend this to a friend, and I would most definitely buy the same brand again. It is so great and I can't wait to recommend it to everyone!

"AIR CONDITIONER REVIEW"
Lennox is a well known trusted brand and I have owned this air conditioner for almost two years. I like that it runs smoothly but I don't like that I can hear it so vividly and I expected it to be almost silent, from the way the company advertised it on the box. I don't like loud machines, especially when my two year old is napping. But on the other hand, I have not had to repair or replace it yet. I would buy the same brand again and recommend it to a friend because its inexpensive and worth the cost. This machine puts out very cool air; the air is almost colder than the one in my freezer.

"my lennox air conditioner"
When i was looking for a air conditioner which is highly efficient in cutting down the fuel costs i found this brand - lennox x21.I purchased this air conditioner 3 years back and it is working great since then.What i like the most is that it makes very less noise. My power bill has significantly reduced after i switched to this product. this air conditioner is highly efficient and also has earned energy Star label .While maintaining a cool, low-humidity home environment ,It runs on low level upto 80 % of its time which helps in less power consumption It has 2 levels of settings , one for hot days and the other for milder days.It also Comes with a 10 year warranty on its parts. This Air conditioner also has a self monitor which monitors the performance and helps to report if there are any issues. this Air conditioners can also combined as intergrated systems though I haven't tried yet to do it. I would highly recommend this airconditioner especially for warm areas due to the hot weather for most of the year.

"lennox two stage xc21 a/c system"
I had a lennox xc21036 a/c system with a variable speed air handler installed 2 years ago. This system provides the best cooling that I have ever had you don’t even know it is on most of the time. I replaced a carrier builder model that was only 5 years old that I was having lots of trouble with. and changed contractors (I found a contractor that knows what they are doing) the new construction contractors don’t do a very good job of duct sizing and installation this was most of my problems.
Other XC21 Reviews
Online posters have mostly positive things to say about the XC21, especially its high SEER. However, one poster in this online forum thread says the unit was not as efficient as he had hoped. Other posters attribute this to the model being a large one.
One poster in this thread says the XC21 appears to be a good value for its high SEER rating.
XC21 Warranty
Lennox covers the XC21 with a 10-year limited warranty on the compressor and all other parts.
