Overview of the XP15
The Lennox XP15 heat pump offers high efficiency heating and cooling up to 16.7 SEER and 9 HSPF. Advertised by the manufacturer as the "quietest heat pump you can buy," the XP15 features cooling operation as low as 63 db.
This model includes the Lennox System Operation Monitoring, which constantly monitors the unit in order to provide quick and easy diagnostics for a technician. Additional components include a heavy gauge, pre-painted steel cabinet; scroll compressor; high efficiency outdoor coil; a soft operating fan; and noise-suppressing fan grill.
The XP15 is compatible with Lennoxís Humidor whole system dehumidification system for increased air quality and climate control. It is also Energy Star-qualified, and carries the Good Housekeeping promise.

"Good Unit but unresponsive company"
I own two Lennox heat pumps. I wanted to find out the lowest effective temperature of operation. Called Lennox, could not tell me. Called their Technical Service phone number and was told they can't tell me that information. Only a dealer can receive that information. My reply was I can be the responsible party to pay for the two units but I can't get an answer to a simple operational question. The answer, Yes. Not good company service.

"Few tough years, now great"
After much research I chose to upgrade my 45 year old furnace and eight year old heat pump with Lennox end of December 2006 costing $6200 installed. The xp-15 heat pump had a system operations monitor, which sounded like a plus. Musts were energy efficient, quiet, and new refrigerant (which wasn't required yet. But I wanted, at additional cost of $500). With new system, winter and summer bills dropped $50-$100 month. The heat pump unit at 63Db is very quiet; inside house with new Lennox Elite furnace, unless you see something by vents moving, wouldn't know it was on; everyone comments on it. Now for the bad - for the first three years, every season change there were problems; adding up invoice costs for that time totaled about $700 for replacement of txv valve, coil, defrost sensor, defrost sensor coil. Apparently the sys. Ops. Monitor wasn't very helpful, lol. Finally repairing a crossed wire in H.P. (so tech said) fixed it. Viola, that was the last of seasonal repairs. After 2 1/2 yrs. Of quiet, efficient heat and a/c, Feb. 2015 was 1st repair needed at $479 to replace defrost board in H.P. I've paid for a maintenance pkg. Yearly with a great local HVAC company, giving me priority service (a must!) calls, reduced rates and a furnace and heat pump tune up. The H.P. is 10 years old now, I'm hoping it is as good as my next door neighbor's, her Lennox is 17 years old and works great. I'd be hesitant to buy a Lennox H.P. again because, based on reviews, sounds like blades are plastic and ice up - we get cold in Ohio. I'd look at Trane, as neighbors and friends have had very good luck with their units, and they are reasonably priced.

This was sold to me as the top of the line unit. "Better than any other brand on the market". I've had to have motors replaced and now the condenser is shot. All of this breakdown is within the warranty period. Sure the part will be replaced at no cost but the labor is outrageous, which I would have to pay. I've had Spring and Fall check- ups on the unit since it was installed. Lennox should be ashamed to sell this unit. With this poor quality Lennox should cover the labor or replace the unit. PS: There was very little reduction in my electricity cost.

"Lennox breaks down every 6 months."
Purchased a new Lennox furnace and Lennox xp15 heat pump in 2007 from Brennan Heating and AC. Brennan has been quite good. But the heat pump from Lennox has been a dog. I literally need to have a service technician out every season (twice a year in winter and summer) to fix/repair/replace parts/re-seal/add refrigerant. When it gets cold and I turn on the system the heat pump moans and chokes and wheezes and I need to call for service. When the temperature gets hot and I turn on the ac the heat pump sputters and locks up and I have to call for a technician. I would never buy a Lennox heat pump again.

"Doesn't work. Don't buy!"
This Lennox heat pump was in the house we bought about two years ago. We lived in Oklahoma that time and we didn't really get high temperatures that require continuous air conditioning in the summer. That's why it took us so long to realize that the heat pump wasn't working at all when we moved in. We later called the furnace company to repair it and they did fix it for that time and it worked for about a month after that, then it stopped working again and until now we have given up because it doesn't work at all. No real explanation for why it had shut down on us, except "probably something to do with the electronics". It worked for one month and I remember we spent about $2000 to get it working for a month and that's why we gave up trying again. I definitely would not recommend this pump to anyone who would depend on it for AC purposes.

"Getting our 2nd motor in four years."
We've had this unit since 2010 and it now needs a new motor, again. This one lasted barely 1 1/2 years. Motor covered by warranty but the service charge to install it isn't. Costing us between $300-$400 each time. Works well when it's running, but can't trust it and tired of paying to fix it.

"Avoid Like the Plague"
Heat pump came with the house we bought 11 months ago, house was new in 2007. Living in the Vancouver area, we don't really get the temperature extremes that require continuous air conditioning in the summer. So it took a little while to figure out that our heat pump wasn't working when we moved in. We called in a furnace company, $1650. It worked for the next day we needed it, then it was fall. But the heat didn't work properly anymore, we had to rely on the "Emergency Heat" function. Gas bills went through the roof. We were able to get the heat pump working for the A/C for one day this year. Called in the techs again, they got it working, $350. No real explanation for why it had shut down on us, except "probably something to do with the electronics". It worked for one day. So basically we've spent $2000 to get three days of air conditioning, and for the privilege of having 10 months of gas bills that were 50% higher than they should be. In fairness, two other neighbors in our development have the same model, and have had no problems with it. For one, it doesn't have the juice to cool their whole house (2400 sq feet over three floors). The other has no complaints. But based on my experience (and the other reviews), I'd really stay away from this one.

Had installed in 2007. Had problems from day 1. Service had to be called out at least 6 times in first month. Very disappointed in this so-called name brand equipment. Will never recommend anyone to buy this product. Regional and national assistance absolutely no help at all.

"LENNOX HEAT PUMP IS A "LEMON" - NEVER BUY LENNOX"
I purchased a Lennox xp-15-042 Heat Pump in March 2007. Had 18 Service Calls since installation, not including 2 yearly maintenance service calls. Every January and February (wintertime), this heat pump failed...either low pressure lockout or running continuously. Both problems caused high electric bills due to running on resistance/backup heat. Spent $3800 on electric bills alone due to this heat pump's failure each winter. Unit is a total "lemon." Neither Lennox nor the Attorney General's Office would provide any assistance, resolution, or replacement. Never ever buy a Lennox heat pump. Lennox doesn't stand behind their products and cares even less about their customers.

"Leaking freon gas"
My less than 4 year old #xp15-042-230-01 heat pump leaked it's freon gas and shut down. The repair bill came to $976.22 ! The soldered joint where the suction line enters the compressor was cracked. The technician who repaired the leak said this had been a quality control problem caused at the factory. Lennox refused to warranty the heat pump because there was not a broken part ! They also said " how can I expect a joint to last longer than 4 years.? " This has been my 1st experience with heat pumps and it has not been a pleasant one.

The biggest mistake I made when building my house was installing Lennox heat pumps. I have 3 xp15 signature units ($ 18000). I have had numerous service calls. The most recent for a refrigerant leak (unit is less than 3 yrs old). I have replaced the motherboard & compressor before. Hell will freeze over before I purchase another Lennox item of any sort & I will do anything to dissuade anyone from purchasing any Lennox products. Any questions email me.
