Rated 5 out of 5 by RSinAZ Two units installed. I live in Arizona and the heat is blistering here. I recently had 2 XP21 systems installed at my house. They are very quiet while keeping my home comfortable. I highly recommend. November 22, 2012
Rated 5 out of 5 by StephenM Big savings on electric bill. This is the first time I have ever purchased a 2 stage heat pump and am so glad I did. The unit runs at low speed the majority of the time it's on and my electric bills have dropped significantly; some months up to 40%. The air handler is in the house near our family room and we barely hear it running. The best feature I think is being able to set and control the humidity level for the house. Lower humidity = a much more comfortable home without having to freeze everyone out during the summer. I highly recommend this system to anyone. November 18, 2013
Rated 5 out of 5 by Will82 It really is "State of the Art" the Ultimate Heat Pump This system has really improved our comfort in the home while cutting our utilities by over 25%. It also cleans and purifies the air throughout the whole home. And being able to control it precisely from anywhere n our cellphone is a huge added benefit. We love our new Lennox system it was worth every penny and then some. June 6, 2013
Rated 5 out of 5 by Charles24 Nice system This system has lowered my electric bill two months in a row. It runs quietly. We had a drain backup last week, and the thermostat disabled so I would have to call for service instead of letting the unit keep running. This likely saved my flooring. If the unit would have kept running, it would have leaked water. Energy efficiency, icomfort thermostat, and financing incentives were my reasons for purchasing this system. April 23, 2013
Rated 5 out of 5 by Fess WOW Replaced a 22 year old heat pump with this one, was going to get the XP17 but rebates brought price down on the XP21 to essentially the same so went with the top of the line. It is amazingly quiet outside, also has the 2 stage blower in the garage which you barely hear also. Use to be able to hear the air blow inside the house with the old pump, no more with this one. Also upgraded to the carbon filtration system, also wonderful. Takes smells out of the house fast, also has decreased house dust by 80% and I was using 3M allergen filters before which are suppose to be one of the better filters out there. Love my new purchase!

Rated 5 out of 5 by abilenebull This HVAC unit has helped us lower our monthly bills! This unit has helped us stay warmer this winter. And while staying warmer, we are seeing lower daily usage and monthly bills! March 2, 2013
Rated 3 out of 5 by Suzanne7 More noise than expected The headline says this is "the most quier and efficient heat pump you can buy.". It is not as quiet as my old unit. It makes much more noise than I expected. It seems to work very well in heating the home, so that is good. But it makes noise. February 13, 2013
Rated 4 out of 5 by agilegal Very efficient product I bought this unit for the dual stage and high efficiency, and it has proven itself in the short amount of time I have had it. Would recommend for these reasons. February 5, 2013
*This chart compares the 5-year savings you can expect from a 18.20 SEER/9.70 HSPF heat pump vs. existing equipment with a 10.00 SEER/6.80 HSPF rating and industry-standard equipment with a 13.00 SEER/7.70 HSPF 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 800 cooling hours, 2,250 heating 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.
