Overview of the Signature
The Lennox Signature heat pump series consists of three units models ranging in SEER ratings from 18.5 to as high as 23.5 and are all Energy Star qualified. The HSPF on these units ranges from 9.7 to 10.2.
Each of the units feature the manufacturer's proprietary Silent Comfort technology, which delivers sound levels as low as 63dB, and a silent cover fan grille that keep operation of the composite fan blades quiet. The Silent Comfort feature utilizes sensors that cause the blades to rotate faster in the event of being covered by debris or ice. The units are surrounded by a galvanized steel cabinet with a baked-on powder finish, and the steel base is coated with zinc for durability. The XP25 uses Precise Comfort Technology, which makes frequent, small adjustments to best maintain interior comfort.
Among other options, the Signature heat pump series can be combined with SunSource solar modules that power the heat pump, resulting in what Lennox claims to be a 50-percent reduction in cooling and heating bills. In addition, when a Signature product is installed with the iComfort Wi-Fi thermostat, the compressor can make 1-percent output adjustments. iComfort-enabled technology is available for communication among home comfort components.

"XP21 Lennox heat pump"
Our new Lennox system was installed in the fall of 2013, replacing one from 2001. It consists of (1) two Signature Series (XC21/SL280V) units for our main downstairs living area, and (2) one Signature Series (XP21/CBX32MV) unit, which uses a heat pump, for an extra room above the garage. The total cost of the units was $35,603 minus $3,000 rebate. All units are advertised as having “Ultra Quiet Operation.” However, the outside heat pump (XP21) is slightly noisier than the older one was. The major problem is this: when it rains or snows with temperatures falling below about 36 degrees, the pump often freezes up. And it does not do so quietly; it groans and moans in the process. The first few nights (yes, nights) I used hot water (via a long hose from the water heater) to defrost the exchanger, but now I just turn the unit off and wait till the next morning to do so. To me, the visible difference between the old and new pump is that the old one had metal fan blades and the new has composite blades on which ice seems to form more readily.

"Error code 413 issue"
The design of this system is so technical, not even the service techs who installed it (<2 years ago) can troubleshoot problems. To call Lennox customer service or Tech support is a joke. The numbers are automated, which sends you into a loop of pushing buttons for the next department or available person...then you wait, wait, wait. On Customer Service line, you just wait, wait, wait. When someone does answer they can't communicate about your equipment or transfer you to someone who can help. They just send you an email to file a complaint with Lennox Corp. Office. I wanted a Solar Ready HVAC system, paid over 25k dollars to have mine installed (not the solar part mind you, that is an additional expense). I'm afraid the vendor, RS Andrews and Lennox are not a good match to provide reliabilty, dependability, quick service or good custom relations. Sorry guys.... It's summer school for you guys!

"Not Suited For Winter Weather"
Recommended and installed by contractor summer of 2011. Winter 2012-13: something sounded like a diesel truck idling in the garden, so loud. Was amazed to see that in fact that is the sound of the fan blades covered in ice hitting the sides of the molded plastic housing. I'm not in Alaska, this is near Washington, D.C. Turned off heat, removed ice. Of course, it did it again and eventually froze in place with motor grinding away. Technician said, all I need to do is to get a hair dryer and defrost it. That's what they do at his office. Can I rate less than one star? A unit that provides heat is needed because it's cold outside. If it's cold outside, there can be ice. It's called winter weather. This is such a stupid design, the plastic housing is all one piece. It's not like you can remove it, so the fan blades won't freeze to it. So the emergency heat goes on, but the real emergency is in the design department at Lennox. What a waste.

I had a Lennox system installed over 8 years ago and it's been running like a champ since the day I installed it. I've read reviews on many brands and can find bad reviews on all of them. What it comes down to is the proper design, duct system and installation practices of the contractor that you use. I will definitely stick with Lennox, and with the best contractors to do the job. Don't take the lowest price folks then complain about the breakdowns. You get what you pay for.

"Broke in under 5 years"
We purchased a house with a 1.5 year old Lennox Signature series heat pump with an oil heat backup. Now, 3 years later (system is 4.5 years old), the factory brazing on the discharge line from the compressor failed and the refrigerant leaked out, which caused the heat pump board to lock out the system. Discharge line was repaired by Lennox authorized dealer and the line failed again within 1 week. They then had to replace the compressor. 1 month later the txv unit on the inside coil has failed, causing the heat pump to stay on defrost mode for 1-2 hours. This system is not reliable and I am expecting more trouble over the years. Perhaps the technicians screwed up in some way causing the txv to fail, but who really knows. I will say though, a factory braze failure should be covered as a manufacturing defect by Lennox, but they essentially were rude and gave me the proverbial "jump in the lake" routine. Customer service is a joke that is for sure, you will be on hold forever and the staff are poorly trained. Based on this experience I will look to go with another company next time around. Lennox may have had a good reputation in the past but I assure you the new corporate management are clueless about how they are ruining the company.

"Expensive, Poorly Designed, Unreliable"
We installed a high-end, Lennox "Signature Series" hvac system three years ago. The problem with the external component of the system is that it is not designed to operate where there is any moisture present (such as rain, ice, snow, or fog). The components corrode quickly, become pitted, the system does not receive full power, and it stops operating. We've replaced the same relay twice and most recently, the entire control circuit board. That repair lasted about one day. So far we've spent over $10,000 on a system that does not work. We're back to using inexpensive, reliable, electric space heaters that provide radiant heat.

"Don't Buy Lennox"
Built a new home and asked for Lennox....what a mistake! They have horrible customer support, poor quality, and don't stand behind their products. Try calling their "Customer Care Line".....it is only available 8-5, m-f and you have to wait and wait. They must have too many complaints! I'm asking my builder to "replace" my three Lennox signature series (top of the line) units - every unit I have has had parts replaced, average one outage a month, and the units are only 6 months old!!!!! Lennox quality is very very poor at best! Warranty? The units will be a money pit the day the warranty expires. I don't recommend them. It is "impossible" to escalate them as well - they don't listen to customers!

"Lennox XP21 Expensive But Worth It"
A couple years ago when our first heat pump burned up after almost 18 years of service we went shopping for heat pumps. Electricity rates were going up, so every time we purchased a new appliance for the house efficient energy consumption was always first on our list. We looked at many different heat pump manufactures but came back to Lennox after having had years of trouble free service from our prior unit. We decided on the XP21 model because it had a very high SEER rating of 19.00. The brochure said it would save us a couple hundred dollars off our electric bill. We did notice a reduction in our electric bill over our last unit although am not sure if it is much as they claim. If you plan on staying in your home for 10 years or more, the XP21 makes sense. What I really like about our new heat pump is how much quieter it is than the old model. Lennox insulates their upper end models much better so they do run a lot quieter. Overall we are really happy with this unit and so far it has not required any repairs. We would definitely purchase another Lennox heat pump again

I just recently moved into my home 1 year ago, and the old heat pump system that was here previous was deplorable. The first thing I asked myself was where I was going to find a new one, what to look for and is it energy efficient, which is important. I was thinking of going to Home Depot to find one, but a friend told me, that she ordered one online that was highly remarkable. I trusted her and ordered a Dave Lennox Signature Collection heat pump. They installed the pump and I was so anxious to see how it worked, would it improve my energy bill and most of all would it be quiet. I'm here to say I am so satisfied with the heat pump that I gave her a box of chocolates! The heat pump is so quiet and so smooth, you can't tell the difference if it's running or off. I was also curious about the darn energy bill, and needless to say my energy bill was cut 40 dollar'S. I thought all those people who were energy nuts, were absolutely crazy to waste money buying energy star product, but they work and help cut down on energy use and well worth the splurge. There is nothing bad to say about this heat pump, only positive. I told all my friends about it, and recommend that they get one also to cut down the cost of their energy bills. I have had it for a little over a year and it's still quiet and cutting down the energy bill. I also still have not had it repaired; it's still ticking and working just like new

We bought two Lennox Signature xp19 units just over a year ago. Barely into the second summer, one of the units stopped working. Defective thermal expansion valve. Parts covered but not the 1,000 labor. Highway robbery. One would expect better when purchasing top of the line units. Wouldn't buy another one.

"Unreliable PC board on exterior unit."
Purchased a Lennox xp-19 heat pump along with a matched air handler/furnace and new ductwork for the house over Memorial day 2010. 2 weeks later, the unit stopped cooling. Some air was coming out of the ductwork, but not enough to keep the house cool. The 'diagnosis' was a failed PC board on the outside unit. The service technician asked me if I wanted a board from another system, and I told him NO. I paid for a new unit, I want a new PC board. He bypassed the board and I was able to keep the house cool, however the variable speed/zoning functions were also bypassed. A week later, the replacement board arrived from Lennox and he installed it. Everything appeared to work fine. Until 1 week later, when the system stopped cooling again. Same symptoms. I've had this system for 1 month, and the technicians have been here 5 times now. Luckily, I have a 10-yr warranty on parts/labor with my service company and guaranteed 24hr service. My question is why are the PC boards so flakey? I could breathe on one and make it go out.

"Lennox Heat Pump System"
We purchased a Lennox HpX15-60 heating and air conditioning system in Nov 2005. In July of 2008, the condensate failed and caused major damage to our ceiling and wall from water leakage. Then in the winter of 2009, the heat pump failed and after two months of repairs the unit was replaced with another Lennox heat pump xp19-060-230-05. This system shuts off after running for a few times and will not come back on until it sits for hours. I have a tech coming out on Wednesday (same company that installed the first and second units. I alway use the same company as I want to make sure that I keep paperwork on the repairs. We have spent hundreds of dollars on this system. I am ready to file a lawsuit against Lennox. I can't afford to put in a new system again after only four and a half years with this one. I just don't know what to do anymore.

"A Different Kind of Problem"
Lennox xp19 4-ton system just installed mid-Feb 2010 turned out to be too big for my house. Dealer did not verify the square footage before installing. The blower did not always turn when power came on. Complete system replaced with xp19 3-ton system in early March. Now it works properly and is quite adequate for this house. The problem is, and I have not read of this problem anywhere else, both units emitted a very offensive odor filling the house to such a level that it is irritating to the throat and causing eyes to burn. The dealer said this has never happened before in 26 years he has been in business. With 50 years of living with a/c & heating systems, this is the first time this has happened to me. Since it seems no one else has any positive results from contacting Lennox, why should I bother. Has anyone else experienced an odor problem with a Lennox system?

"XP 15 with lots of problems"
I purchased a "Top of the Line" xp 15 Series unit 2.5 tonnes in August 2007. Since that time, I have had a technician at my home 4 times. Every time the season changes, there is a problem. Have spent almost $1700 on a product that cost me $7000 installed. Consumer affairs in Texas is of no help, if you can stand calling a long distance number and being on wait for 30 minutes. Their "premier service" provider in Montreal called Guaranteed Industries did nothing to champion my cause. It appears from the bills that there are lots of expansion valves being changed and now it is the ambient temperature sensor. All in all a very poor quality.

"Get what you pay for"
We bought out home three years ago and our gas bill for the first winter was $340 a month. I Was livid. It was the original unit(8yrs. old) and was a low-mid grade 10 seer contractor grade Carrier. We bought a Lennox signature series 19 seer Heat pump with a 2 stage motor.Our gas bill went down $200 the next winter and our electric bill also took a nice dip as well. It comes with 10 yr parts and compressor warranty and it was well worth the money spent. 10 thousand For an entire new system, heat pump,furnace,a-coil,humidifier and thermostat. Runs smooth and quiet. My neighbors unit drowns out the sound mine makes. His was replaced last year with a Trane, and is 15 feet away from my unit.For those who had problems with their Lennox units all I can say is mine is tip top, and I had a top notch installer. You get what you pay for.

Lennox XP 15 Heat Pump installed Jan 07 and by early March my electric bills had doubled (energy savings feature down the drain). It was a pressure loss in the refrigerant, over and over and over then many other issues over 11 months. Ran on emergency heat most of the winter. Now the heating system went out and after 55 hours of service calls and missing work and life while sitting home with repairmen, I still have a non functioning system. I feel Lennox owes me for heating bills out of control but they take no responsibility.
Other Signature Reviews
According to online reviews, many consumers are happy with their purchase of their Signature heat pump--even when a problem has occurred. As one reviewer on the Lennox site explained, when their unit had a drain backup, the thermostat disabled, leading the homeowner to call a technician rather than keeping the unit running. "This likely saved my flooring," the homeowner writes.
However, a few homeowners report that these units can be noisier than advertised. One reviewer says that, in general, the unit does operate quietly, until the thermostat is set to a few degrees warmer. This can cause the unit to operate at top speed, a noisy process. In addition, a number of online reviews include significant trouble with the Lennox warranty.
The Lennox warranty provides a 10-year limited warranty on the Signature heat pump's compressor and all remaining covered components.
