Rated 5 out of 5 by Hitech This thing works This unit is unbelievably quiet as is the EHB XP25 condenser unit. In South florida the humidity is an issue and with the unit set on "Humid" 79 and 50% the temp and humidity in the house never varies and the electric usage year over year is about 25% less.

Rated 5 out of 5 by TonyO Awesome machine! This thing is beautiful! Very quiet, can't really tell when it's on. Combined with the comfort thermostat, it gets the temp where you set it and stays there. My old system would cool too long or heat too much, this thing is precise! July 30, 2014
Rated 5 out of 5 by RRR66 There is only one choice. Having owned two previous Lennox systems I was aware of the quality and reliability of the product. July 8, 2014
Rated 5 out of 5 by MontrealGuy Best Air Handler This is a very powerful air handler with a good filtration system. I like it a lot and it's build quality is very good. The electric heat elements also work very well and it allows me to feel warm in the cold winters where heat pumps can't perform as well. The iconfort capabilty is something that all houses should have, it makes everything so convenient. Also some say it whisper quiet but I think it is noisey. I don't know, it may be because of poor insulation in the furnace room, maybe the duct work is of poor qulaity (my house is really old) but I find it noisey. But the noise is something worth giving up for the quality and power. July 26, 2013
Rated 5 out of 5 by TeamTurtle Whisper Quiet This air handler is whisper quiet; we cannot tell when it is running from the sound of it alone. We walk by one of the vents and go, "Oh, it's on!" February 24, 2013
Rated 4 out of 5 by kever Enjoying it so far Reviewing, but haven't really had time with the system. We have been enjoying it so far, quiet. December 22, 2012
Rated 3 out of 5 by ed347 Noisier than expected This unit is loud when the variable speed fan is slowing down. Loud enough that it will wake us up through the night. I expected a very quiet unit from what I was told, now I have to put insulation on my basement ceiling to quiet the noise. I was told by the company this noise is normal. December 13, 2012
Rated 5 out of 5 by JTinNC Good combination of features for the value. I upgraded from an a single stage to a two stage heat pump and I am very glad I did. The CBX series variable speed air handler is quiet and efficient. The longer run time in stage one cooling allows for improved dehumidification while saving energy. December 5, 2012
