The Lennox XP16 is a two-stage heat pump with an efficiency rating of up to 17.00 SEER and 9.50 HSPF. The XP16 is designed to run at low stage more than 80 percent of the time, resulting in even temperatures and higher efficiency. A precision-balance, direct-drive fan helps to keep sound levels as low as 74 dB. The unit's SmartHinge louver design allows quick access from all sides for easy maintenance while protecting the coil. The cabinet is constructed of heavy-gauge galvanized steel with a corrosion-resistant baked-on powder finish.
I purchased a Lennox hybrid propane gas furnace and XP16 Elite heat pump in the fall of 2009. Three years later, the compressor fan motor failed. Of course it was during the hottest part of the summer and it took almost 3 weeks to get the right motor in and replaced. Now after 4 years, the compressor and check/expansion valve died. Another 3 weeks to get the parts in and the HVAC mechanic spent nearly 7 hours replacing. Came to find out the replacement compressor is smaller than the original which causes a problem with coupling the crankcase heater. Now, a new crankcase heater (heats the oil in the compressor during extremely cold days) has to be ordered and installed. I'm lucky that the only charge thus far is a $75 trip fee from the HVAC company. I have no confidence in this unit and expect more problems down the road. Very disappointed with the Lennox product. I've owned York and Carrier products that were much more reliable.
This is a revision to an earlier review in March of 2012 which you can peruse if you wish to know the details of the story. I am upgrading my review to Neutral since Lennox finally agreed to replace my entire heat pump (inside coil and outdoor unit) for free. I needed the intervention of the hvac contractor to help me. I still had to pay for labor which cost $2400. I am out almost 4k for a heat pump that should never failed but at least I got a new one. My recommendation is to always buy the extended warranty on heat pumps. The cost of the warranty can easily equal the cost of one repair.
To say that I am unsatisfied is at the least a gross understatement! After spending 15k for an oversized unit (according to pg&e) the system has never performed to expectations. Utility bills have been astronomical. Calls to the dealer/contractor were answered with statements about my credibility. On 2 separate occasions it failed to turn on altogether. I was charged a service fee as the technician informed me that the repair was not a warranty issue. I would not recommend Lennox to anyone under any circumstances.
Many of the questions regarding the XP16 on online forums have to do with installation prices and the cost of use. A member on hvac-talk.com advised that the two-stage unit is more for comfort than savings and will heat or cool more evenly and remove more humidity. A consumer on hvac-talk.com choosing between the XP16 and a comparable Carrier unit decided on the Carrier because it was advertised as slightly quieter.
Product registration is required within 60 days of installation for maximum warranty coverage. The warranty for the Lennox XP16 heat pump is comprised of the following:
10-year limited warranty on the compressor
5-year limited warranty on covered components
An Extended Limited warranty and a Complete Care Plus Extended warranty, which covers parts and labor, are also available.
