Rated 5 out of 5 by 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 heat pump This review is after one month and system is working find after some inital problems matching with our existing three zone system. we also purchase air filtering system and can already tell air is cleaner we don't have to dust furniture as often. September 25, 2014
Rated 5 out of 5 by This product has great features This product is very energy efficent and quite to run. August 27, 2014
Rated 5 out of 5 by Very quiet and runs very effectively The unit is as discreet as is possible for the size of it. The two stage unit helps to keep it from running so often, and even when it does run, it is hardly heard in the house. Being compatible with the IComfort makes it very nice. Also with being compatible with a solar powered energy source makes it great that we will be able to continue improving our house without having to change the heat pump in the future. August 20, 2014
Rated 5 out of 5 by Big & quiet The unit is much larger than it's predecessor. Which is not a bad thing. But it is quiet and works beautifully. August 10, 2014
Rated 5 out of 5 by This works even better than expected. I love the features on this model. The thermostat is easy to use and provides a lot of information on how the system is performing. It's so quiet we can barely hear it. We initially considered a cheaper model but we are very glad we went with the XP21. August 8, 2014
Rated 5 out of 5 by Very pleased with this system. Couldn't be happier with this system. It's a bit pricey, but you definitely get what you pay for. August 7, 2014
Rated 5 out of 5 by 21 Seer rocks! Love the XP21! Quiet and 'Cool'! A HUGE difference from our old 13 seer unit. Had our home cooled down in no time flat. And considering that Texas summers' can really put your A/C to the test, that's saying something. Seriously. July 25, 2014
Rated 5 out of 5 by TOP QUALITY EQUIPMENT This System, so far, is 100% better than the System I replaced. The unit is quiet, and with the recirculating feature, keeps the house at an even temperature. The air is cleaner, and feels virtually dust-free. Great choice..., Great Unit! July 14, 2014
Rated 5 out of 5 by This product has excellent features This system is quiet and extremly efficient. It is already saving me money and you can't hear it running unless you go out by the unit. July 2, 2014
Rated 5 out of 5 by Works great Never hear it. House is cool in summer. Exactly what we wanted. June 26, 2014
Rated 5 out of 5 by Very pleased with low noise level Very happy with the performance obtained both from a heating and cooling perspective. June 25, 2014
Rated 5 out of 5 by Wow, welcome to the 21st Century! Nice system. The fans in the attic can be regulated from the Wi-Fi thermostat. This is good due to differences in existing ducting and required ducting. (i.e.) replacing an old system. I am going to slide a barstool up to the thermostat so I can pilot the Enterprise. What a difference in technology, and what a savings on electricity! What fun...get one. April 9, 2014
Rated 2 out of 5 by Lousy product. First problem it was not quiet until repairman made a fix. Second problem it had a part blow out while we were on vacation. That problem although known by the company to exist it was not fixed until the problem occurred at our house. It took a simple little round black sticker to prevent the problem from happening again, after the furnace was repaired. Next time a circuit board blew out because of a storm. The company had to take our old board so it could be studied to determine what caused the problem. They knew what happened because they already had a new board. During this latest mid-Atlantic storm our furnace received and error message. I was able to get someone on the phone who told me the possible problem and had me turn on the emergency heat. A service tech was not available because of the storm. On Friday the tech arrived and found that an entire board had blown so it was more than the first tech had thought. In his defense he was not able to see the heat pump. A new board was not immediately available so a service call is set for Monday to replace this board. We have learned that this particular model has had a lot of problems since it was first produced. We had been told at the time we purchased it that it was a new top of the line product. I am highly disappointed in the product, although I will admit the service men have been very good. For the amount of money paid I feel the whole product should be replaced. The product has also not produced the amount of heat we were promised or the house coverage we were promised. February 16, 2014
Rated 3 out of 5 by Overall, seems to be a solid unit, but noisy Have operated the system for 4 months, both in cooling and heating mode. This 3 ton rated heat pump system seems to put out much more heat than our previous 3 ton system. I note the backup electric resistance heaters rarely come on, even at 10F ambient. The outdoor unit is noisy; agree if you stand 10 feet away horizontally it is relatively quiet. But vertically, much of the fan noise is heard and transmits through second story bedroom window and wall. There is also much vibration in the refrigerant lines which partially transmits through house structure. February 12, 2014
Rated 5 out of 5 by 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 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 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 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 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 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 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
Rated 5 out of 5 by a warm house before the lennoxs system I had two heat pumps to try to heat my house that did not do the job We now have AIR comming out of ouy vents and is is warm January 12, 2013
Rated 5 out of 5 by Great performance and price We replaced an old single stage heat pump and are extremely pleased with our new heat pump. It is much more efficient and keeps our house much warmer. The variable speed fan set to circulate eliminates cold spots in the house. Just got the electric bill and it is almost 1000 KWh lower than the average of the last 8 Decembers, even though we had below average temperatures for nearly 2 weeks. We are very happy! January 8, 2013
Rated 5 out of 5 by Great features and function In the few weeks we have had the system we can tell a big difference with the air flow in the house. Before you could not tell when the system was running in the back bedroom. Now you can both hear and feel when the system is running. It has increased the comfort in the house and we are hoping to see the benefits in the electric bill. January 6, 2013
Rated 5 out of 5 by Works even better than expected. Even though it is a little pricey, so far it does everything we wanted it for. The comfort thermostat is great. Once set it handles everything and you can change setting from your smart phone, iPads or computer. So far so good. January 4, 2013
Rated 4 out of 5 by Good features and quiet Bought this in mid December during a warm spell. It was a week or more before the heating task was tested. The programmable thermostat worked well and the heating was done as we wished. The unit is very quiet except when you decide to raise the temperature by a more than a degree. It then goes into its highest speed mode and is fairly noisy. Fortunately is does not operate in that mode very often. January 3, 2013
Rated 5 out of 5 by This product has many good features. The cost savings and increased comfort are the two most important features. December 30, 2012
Rated 5 out of 5 by very quiet Our units are ultra quiet, which we really like. We've had heat pumps before, but this Lennox product is true quality. The thermostat is very user friendly and we like being able to set it and forget it. December 29, 2012
Rated 5 out of 5 by Very efficient and quiet This unit works very well, and it's so quiet. Also love the display on the control with all the options. December 24, 2012
