Rated 4.4 out of 5 by 47 reviewers.
Rated 5 out of 5 by Great product Unit works great. More efficient. Very happy with product. July 12, 2014
Rated 5 out of 5 by This unit works very well We noticed an immediate improvement over our previous unit, not only in cooling features but air flow within our house, even on the 2nd floor. July 10, 2014
Rated 5 out of 5 by This product works very well I recently purchased an XC14 Elite Air Conditioning unit as a companion to my Lennox furnace. The unit has performed very well in the extremely hot spring & summer that we are experiencing. It goes on at the requested temperature & shuts down once it is attained. The unit is very quiet & I am scarcely aware that it is running. The actual outdoor unit is attractive, sturdy & very quiet. I would highly recommend any Lennox product based on the two I presently own. July 9, 2014
Rated 5 out of 5 by Couldn't Ask for a Better A/C This A/C works so well. Here, it gets hot, humid and sticky. When we come home from work we are instantly grateful. Also, I now don't have to worry about my pets getting heat stroke this summer. Its very quite and has strong blowing and cooling power. Couldn't ask for a better A/C. July 9, 2014
Rated 5 out of 5 by Efficient and Money Saving We have had the new unit in for a month now, and the consistency of the temp in the house is spectacular. It is keeping the upstairs at 73 consistently, without apparent strain. We recently purchased an electric vehicle, which we plug in at home, but after installing the new AC unit, our electric bill was actually lower than even prior to adding the electric car. I am anticipating the unit will pay for itself rather quickly. I am glad I didn't end up going with one of the discount units that were being advertised in mailers at the time of my purchase.

Rated 5 out of 5 Works so great! Best choice! We are so happy that we chose this product. We had so many options but knew that this specific A/C was perfect for our home. It cools our home wonderfully, isn't too loud, and has had no problems for us whatsoever. It's very clean and neat looking, and keeps our home and family cool and happy in the summer time.

Rated 3 out of 5 by This product is easy to operate. The air condition seems much larger than the first one we bought but I guess it doesn't really matter. But it is much noisier than our original one and because it is installed outside my bedroom wall I can't have it running at night as it keeps me awake. July 2, 2014
Rated 5 out of 5 by Great Unit Quiet and efficient. We never pay much attention to the outside temperature. July 1, 2014
