Rated 5 out of 5 by torq455 Shhhhhh!
This thing has some serious cooling power! I couldn't believe how quiet and smooth this unit runs. Standing 15 feet away, I couldn't tell if it was running! I can hear the neighbor's A/C unit kick on on the other side of the house! lol I felt pretty good going with another Lennox A/C unit. The last one was installed 21 years ago! I wouldn't have replaced it if it wasn't for the coil drip pan rusting out!

Rated 5 out of 5 by diz2014 Quiet!
They said it would be quiet but it is so quiet you can't tell when it's running. As suggested, we keep the fan on and can't even hear that. Installed in May, now July and the system is great (along with a Lennox variable speed 2 state gas furnace).

Rated 5 out of 5 by jonsaint The Lennox XP21 is a great buy and a real money-saver
The Lennox Signature XP21 is an efficient and verified-good value system that runs super quiet. The two-stage air conditioning keeps us more comfortable and saves us money as it is a SEER 21 system.
Mine is paired with a Lennox Signature SL280UHV horizontal air-flow gas furnace and a Lennox icomfort Wi-Fi thermostat to give me excellent efficiency, quiet operation, and the ability to control my house's conditions over the Internet if I want to.
And my wife says the house is ever so much more comfortable since we bought the whole system.
The financing options were budget-friendly too.

Rated 5 out of 5 by kctigerfan The XC21 is quiet!
My new XC21 is exceeding my expectations. It really cools my house down so much better than my old AC. Not only that, but it's a lot quieter too!

Rated 5 out of 5 by careerstudent30 This is the "Cadillac" of air conditions
This unit is extremely easy to use and very quiet. It offers a great deal of new technology features that are very easy to access and operation. The wi-fi capability is really a plus to regulating temperature both in home and away. The energy savings are all ready beginning to roll in!

Rated 5 out of 5 by RedRaiderRick Product is quiet and efficient
I am pleasantly amazed at how quiet the compressor unit is, and how quickly it cools our home. I especially like the thermostat that was installed with the unit, and the many options it has for operating our system.

I just purchased this unit when AC went out. Even though was not in budget plans glad I have the new system with air purification system. I can really tell a difference with air quality. Additionally, love how quiet the system operates and am really satisfied overall.

Rated 5 out of 5 by MikeEC Super quiet
We got the 2-ton XC21, and while it's larger than the competitor unit it replaced, it's super quiet which is important to us since it's located right next to our patio. We can actually hold a conversation without it being disruptive like the previous unit. The Energy Star and SEER ratings were the other reason we went with the XC21.

Rated 2 out of 5 Have had a repairman out seven times in three years
Way too many problems with breakdowns. Now I need a new fan. Haven't had air conditioning for four days now. I have had seven service calls in three years.

Rated 5 out of 5 by CoolnComfy Best investment we've made!
We own a 2-story town home which was always difficult to keep cool in the hot Orlando area weather. We've had our unit just over a month and couldn't be happier or more comfortable...in the middle of June! Our first power bill was reduced by nearly 25% and it wasn't even in use for a full month.

My old unit was 29 years old and I thought it actually worked. I had no idea how much better the climate in my house could be. The consistent temperature and humidity is amazing. Extremely satisfied!

Rated 5 out of 5 by flippy the house feels like a meat locker. The Lennox AC is quiet efficiency.
We can barely hear the Lennox when it is in operation. It is so quiet and efficient. The house is always comfortable.

Rated 2 out of 5 by sadly2muchnoise Noisy compressor
I purchased this air conditioner as part of a complete system purchase along with the SLP98 furnace. After installation, I noticed this air conditioner had a very loud compressor especially on initial startup. It surprised me because I purchased this primarily for two reasons: noise level and efficiency. I wanted a fairly low noise system but it didn't provide me the level that I was hoping for. In fact, my previous 17 year old unit wasn't much louder than this brand new unit. Cooling performance appeared to be good though. Just the amount of noise from the system was what disappointed me the most. Even after trying a few ideas to cut down the noise, the compressor is fairly loud when operating.

I purchased this unit almost a year ago. I have had no problems and my highest bill was barely over $100.00 and I live in South Florida.

Rated 4 out of 5 by Murry Excellent Wi-Fi Features
This unit is very quiet and very pricey. For the price one pays they should include labor cost for repair for at least 5 years if they stand by there product . So far I never seen this unit go into high speed. Even when the temps reached the high 90's only time will tell !!

It is the only AC we have owned that will keep the actual indoor temperature the same as the setting on the thermostat. Cannot hear the indoor unit running!!

Rated 5 out of 5 by joejk Very quite in low speed.
The unit runs very quiet in low speed and so far has not had to go to high speed. Is just slightly bigger than an old 14 seer unit that was 11 years old. Keeps the humidity to the preset level with no problem.

Rated 5 out of 5 by Snatchmo Works great, cools quickly & quietly.
The dehumidifier works quickly, reducing the energy needed to cool the house. It is very quiet, particularly in the single stage mode. I'm waiting for my first electric bill to see how efficiently it runs.

Rated 5 out of 5 by ssbn654 Highly efficient and Quiet
Love these units! My neighbors were scared that the units were going to create a disturbance to their sleeping. When they were running, I had to go over to them to explain that the units were running. They stated "I can't here them" I said "I Know but I can here your window unit on your second floor". These units are so quiet that having them outside of our window doesn't even bother us. The units 2 stages save energy and keeps our electric bill down as well as keep us comfortable.
