Rated 5 out of 5 by This product has proven to meet my expectations This unit has helped me stay on a budget and keep my home warm and cozy this Fall. One of the things that stood out about this unit was being able to purchase and install in steps since I am on a budget. I am now looking into what additional items I can add in the near future. Thanks Lennox for such a great product. October 12, 2014
Rated 5 out of 5 by Outstanding product and savings We installed this handler in conjunction with a Lennox 3.5 ton unit. This system has already shown that it cools better and more efficiently than the outgoing combination. The savings on our electric bill is over 25%. The blower in the handler is incredibly strong and the micro filtration with UV light is a great option; especially if you have allergies. We are very pleased with our purchase and the quality of the product. September 21, 2014
Rated 5 out of 5 by Air movement is handled so efficiently It is even in its air distribution through our home, and very quiet. It starts and stops quietly. September 18, 2014
Rated 5 out of 5 by quiet We wanted a quiet unit and this air handler meets that requirement. September 12, 2014
Rated 5 out of 5 Smaller than old unit It is quite and has a smaller footprint than what it replaced. I believe the air flow is slightly higher as well. That was important since I have some long duct runs. August 15, 2014
Rated 5 out of 5 by Good product features well respected on the industry Had this air handler installed about a month ago. No issues or problems so far. It definitely moves the air and has made a noticeable improvement in the comfort of my home. August 6, 2014
Rated 5 out of 5 by Efficient and relatively quiet About 7 1/2 weeks ago, we had to replace our downstairs unit made by a competitor brand in a home we've owned just over a year. This air handler is in a closet in the laundry room, and though I can hear it in our master bedroom when it cycles on, it's really more of a low-decibel white noise. It's more ambient than anything else, and it certainly is not disruptive. Otherwise, I don't hear it come on at all while we're in the great room or kitchen area. Our first electricity bill was just over 10% lower than last year's, so on that end, we've been pleased. August 4, 2014
Rated 5 out of 5 by Quiet and reliable We have only had this system for less than a month, but we are very pleased with its performance. The temperature never varies, so your comfort level is consistent. June 24, 2014
