Lennox XP19 Heat Pump Overview

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

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.

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.

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.
