Overview of the XP19
The Lennox XP19 heat pump is a discontinued two-stage heat pump with a SEER (cooling efficiency) measured at up to 18.6. This model is not currently manufactured, but may still be available through dealers. The XP19 runs at a lower capacity most of the time to reduce noise and energy costs. It has a heating efficiency of up to 9.3 HSPF. This heat pump utilizes R-410A refrigerant, which is ozone-friendly and EPA-approved. The XP19 was a part of the Lennox Signature collection.

"Expensive but cheap"
This replaced a Lennox heat pump in 2009 that was really old house built in 1982. Fan motor quit in 2015, ran up electricity bill in winter. It's 2017 and​ hot air came out of vents In cooling mode, bad defrost board. What a waste of money is this dog. I should have bought a Trane or anything else

"Bad, bad, bad service."
The unit seems OK after 8 trips by the installer (**** ****** **********, Peoria, Arizona). I give them a 1 (1-10). It took 8 trips to get things working, including replacing the compressor, realigning the compressor box and thermostat, installing some insulation, getting the fan to work properly, plus other adjustments, plus there was an opening in the outside unit that allowed a rat to enter and chew the wiring. The tech replaced the wire but no attempt to fix the insulation the rat had ruined.

"Ripped it out"
My "top-of-the-line" Lennox XP19 was installed in 2006. It has been nothing but trouble. Even though it is still under warranty, I had it ripped out this year and installed a Trane. Lennox corporation is no help, and our local dealer is simply inept. I threw money at this thing every year and it still failed constantly. I went through the winter of 2014 on emergency heat mode. Anyone reading this, do yourself a favor and do not choose Lennox.

"Have Two Units, One Is A Complete Dog"
About 4 years ago, we had two identical XP19 Lennox heat pumps installed within about 6 feet of each other at our estate residence. From the start, one of the units has behaved badly while the other worked as expected. The units were installed by a high-end contractor from Charlottesville who had installed three other (Trane) units at our other properties. Their work was great and their response has exceeded expectation. None of the Trane units have ever given us problems. In contrast, one of Lennox units has worked poorly from the start. It has had board failures several times, repeatedly frozen up, and generally functioned inconsistently. It has repeatedly gone into defrost mode in the winter, lowering the interior temperature 3 to 5 degrees and then shut down or frozen over. Sometimes, it would run and run and generate little or no heat. Other times, it would repeatedly go into 2nd stage, make little heat, and run for hours while the matching unit ran moderately as expected by the weather. Just a few days ago, the faulty unit froze up with 3" of ice on the top and completely ice-filled on the sides - and of course, no heat again. The matching unit sitting beside this defective unit worked flawlessly. Over these four years, our respected HVAC contractor has made numerous trips checking the unit, replacing boards, checking pressures, etc. - all to no avail. After a few weeks, the problems start again. This is just one lousy dog of a unit. Finally, I demanded that our contractor take the faulty unit out and replace it. Apparently, this finally moved the needle so that Lennox agrees to send someone to look (how kind of them). They are arranging to have a Lennox rep here in the next week, but (!) already the Lennox guy is saying it's possibly weather-related. That's simply bunk. If it was weather-related, both units would be affected approximately the same way. Trust me, Lennox, the weather really IS the same when the two units are six feet apart. I am ready to hear all the excuses. The way we see it, we're 100% OK with three Trane systems and hitting a lousy 50-50 with two expensive Lennox units. We'll report what the Lennox guy does (or doesn't) do. Please do look at the photos. Would you really like to see this over and over? George Beker

I bought this heatpump 6 years ago for $9024. From almost day one, it has had problems. I'm presently considering replacing it with another manufacturer's heat pump. It's difficult to know the extent to which the problems are installation-related or equipment related. The installer's service technicians blame the equipment. They tell me that all its energy-saving gizmos result in breakdowns.

Two Lennox 3 ton heat pumps, one on each side of house. Last year, had to replace 5+ year old evap coil. Now, the other unit has a leaking evap coil. This product is super expensive to buy, probably because of all the bells and whistles, but it uses ultra thin copper to improve efficiency at the expense of electrolytic corrosion and leaks of refrigerant. It is, therefore, a piece of junk!

"Piece of crap."
Every 3 months the mountings on the fan kept loosening. After a year and a half the screws on the mountings sheared off. $500 fan replacement after 1.5 years. I'll never buy another Lennox, that's for sure.

"Nightmare Lennox's XP19"
After 30 years of oil furnace comfort, I purchased the Lennox's XP19 in summer of 2006 for $10K. After the first year of use, this system has failed 4 to 6 times a year. The dealer, I brought it from had service my oil furnace and central air for 30 years. After 30 years of service from them, I very unhappy with the level of service from the product (XP19) and dealer. I've had to vacate my home for two days of no heat. The current problem, the dealer said motor condenser has failed and a new motor will cost $800.00. Service call went in 5/25/2011 and part was ordered but won't arrive until 6/03/2011. Poor and more poor service from dealer and Lennox. 90 degree Temperatures have been hovering for over a week. Stuck and hot in St. Mary's County MD. After reading all the reviews here, Lennox's needs to be held responsible for their defective products like SAMSUNG.

"Bought the cadillac, go the lemmon (I mean Lennox)"
I bought the Signature Series XP-19 5-ton, 2-stage heat pump with propane back-up furnace, ERV, Harmoney III controller. I wanted the cadillac system for my energy-efficient insulated concrete house. The first problem was noise - which I've just gotten used-to. The main thing has been that it won't switch to stage 2 without me going to the furnace and pulling out the sensor. The dealer, a Premier Lennox Dealer, has come out numerous times. I've paid for an additional zone, have 3 zones now, for an additional cost. I've paid them over $25,000 so far for this. Yesterday it went into stage-2 all by itself for the first time, I got excited until I realized the air coming out of the vents is only 67 degrees. It's really hot in here! The dealer's on speed dial so here we go again.

"Lennox XP19 with CBX32MV"
I had a Lennox Signature system installed 18 months ago under the Costco program and am devastated. I used a big part of my retirement savings and bought what I thought was a top of the line system hoping it would outlast me. It's total junk and Lennox wants me to pay time, labor and mileage for them to diagnose it and make repairs in spite of the 10 year warranty. It turns out that the warranty only covers some parts. When I talked to them on the phone they said all of the parts they expect may need to be replaced wouldn't be covered (relays, heating coil in the air handler and a switch) since they're "normal wear". So I have an expensive piece of junk and a company who will manipulate the facts so that the warranty is worthless and I pay everything. My son just had to replace his 6 year old Lennox system too, so it's not just a single case. I hope anyone considering a Lennox system looks twice. My recommendation is to avoid a Lennox.

"XP19 System Failure"
Ft Worth Texas: I too decided that it was time to replace the worn out system in my 20 year home, and purchased two three ton Lennox xp19 systems with matching hardware. After the installation, the contractor has been to my home every month thereafter, and has eventually decided that he doesn't want to support the thing anymore. HOWEVER, reading the instructions guide detailing installation of the unit, and knowing a little about installing and maintaining heat pumps, I found several instances in documentation where the contractor simply did not follow instructions. For example, the XP19 installation guide (document revision 12/09), on page 12 clearly indicates that after brazing lines, nitrogen should be used to flush the lines. This was not done. Worse, the contractor did not evacuate the lines (as detailed on pages 17 and 18) before they charged the unit. Also, throughout the installation guide, there are little notes spread around here-and-there about how "If <this process> is not verified/performed, the compressor will fail in the future." (see page 24). And then add to this that the contractor allowed the lubrication to escape from the condensor unit, too. I saw them do it! And when I asked them if they were going to replace that, they said it was not important. I know the lubricant is important, but I have not been able to find the quote. I think Lennox makes a great product. But I seriously question the competency of the installers. Day loborers (ie illegals) did my installation, so I strongly suspect they were not Lennox certified... Blame the contractor doing the install.

"Here we go again! another Lennox lemon"
I first complained about the Lennox Heat Pump at this site in May of 2010. Since that time we have had another Lennox Heat Pump installed because the one that we originally complained about blew up when the company that installed the unit came out to repair and install new parts. These parts, as there were many, were ones that Lennox themselves said to replace. After all that, the unit blew up! Insulation went everywhere and I thought for sure I was going to find two dead men when I went outside after hearing an enormous explosion. The men told me that was it and they were contacting Lennox. They were mad as, well you know. So there I am again with no heat. After 6 weeks of no heat and waiting for a new unit, which was covered by Lennox (only because the owner of the company we purchased it from was one of the men that were at the unit when it exploded)? A new heat pump was installed and looks to be the same as the old one, Make or Model number xp19-060-230-05. This one was installed on January 26, 2010. Here we are in January of 2011 and the same problems are happening again. The heat pump shuts off at least 2 to 3 times each morning and often in the evening. I am told that a heat pump will not come on if temperatures are below 40 degrees. Well you tell me why it would be turning off or going into defrosting mode when temperatures outside are in the low 50'S. And how many times a day does this thing need to defrost? We live in So. California, it just does not get that cold. a unit the size of this should be able to handle this type of weather. I have contacted the company that installed the unit again and they will be coming out again tomorrow. I have had them out for this problem once already in May and again in December. This is an ongoing problem which I am concerned will never be solved and I will just keep dishing out money. I have a folder filled with 12 service work orders since buying the first unit! I also put a call in to the Lennox corporate office. I was on hold for 40 minutes; after a long conversation the representative said they would contact the field tech for So. California. a lot of good that will do because they just contact the company that provides the service to us. Talk about a passing the buck. The only bucks I ever see are the ones I keep dishing out to Lennox and Service providers!

"Nothing but trouble with Lennox heat pump"
I had my entire heat pump system replaced 4 years with a Lennox xp19, and it has been a disaster. The interior fan breaks down about every 9-12 months. I had it completely replaced one, repaired twice more, and now it is broken again and will probably need to be replaced. It is also a very noisy system. It doesn't heat my house very well, and is much more expensive than my previous system. I found out today that the local company that installed the system stopped carrying Lennox (big surprise) so now I have to see if a repair service that is an hour away will come to my house to fix it. I'm ready to scrap the whole thing and start over.

"Lennox XP19 - Satisfied So Far"
Last summer, we replaced a 16 year-old York air conditioner with a Lennox xp19 heat pump. We kept our propane fired Weil-Mclain boiler as supplemental and back up heat and had electric resistance heat installed in the air handler in case the price of propane jumps again. So far, we are very satisfied with the Lennox heat pump. It's too early to run the economics but high temperature in the last 2 days have been in the mid to upper 20s and the heat pump appears to be sufficient to keep up. Propane supplemental heat comes on in the morning when the set back goes off, but isn't generally needed beyond that. We have the air handler set to run in continuous low mode, which seems to keep room temperatures uniform. My wife and I find the house to be more comfortable than last winter but can't put our finger on why. The only change is the heat pump, so it seems to deserve the credit. I have supplemental propane heat locked out if the outdoor temperature is above 30, and am still experimenting with what outdoor temperature to set the heat pump lock out at. Lennox engineering documents indicate that the xp19 has a CoP of 2.9 to 3.0 into the teens, so I'll try to keep it running as long as I can. With a CoP of 3, heating cost should be close to 1/3 of past bills before accounting for supplemental heat. The system's only 6 months old, so time will tell but we're satisfied so far.

"Nothing but trouble"
I have ahd nothing but problems since I bought a Lennox xp19 Heat Pump and Signature series furnace. Initially the furnace would not provide sufficient heat as only 5kW kicked in and even with the heat pump the house was cold. THis took 1 week to fix. The next spring the heat pump was not functioning properly. Now after 4 years the compressor on the heat pump needs to be replaced. THe compressor is under warranty but the labour is not. $500.00 on a 4 year old sytem that cost $13,000.00. I complained to Lennox and did not get a response until one month later, the day after I complained to the Better Business Bureau. Their response, there is nothing we can do.

Comments posted on gardenweb.com reveal that the Lennox XP 19 is considered a "top of the line" model among heat pumps. A homeowner was considering an older model, and an expert answered that the XP 19 was superior to the other model mentioned. A more recent post on the same website shows one expert recommending the product, and another saying to check around and get more estimates.
A prospective customer asks a question on hvac-talk.com in reference to purchasing the Lennox XP 19 heat pump as part of a total package. The customer has also received a quote for the installation of a Carrier system. Two of the experts respond that the Lennox products would be a superior and more efficient system. Another post on hvac-talk.com involves two HVAC professionals talking about how much they like their XP 19s that they have in their own homes.
