"Great system"

5.0 rating
Very Satisfied

Have had this system 12 years and not a single issue. Survives Texas summers like a champ. Have it checked twice a year and replace the filter twice a year and it still runs great!!

"Unhappy with product"

1.0 rating
Very Unsatisfied

Had this unit installed in 2011. Its had many problems and repairs since that time. Apparently the coil has been leaking refrigerant (which seems to be a common complaint). Parts are covered for 10 years, but quotes of a few thousand for labor, so basically almost half the cost of a new unit for a defective part, that Trane must know about. I've contacted the company about our complaints, never heard back. Our home has 2 heat pumps, about ready to replace the second one, but we can't in good conscience go with another Trane model after our expensive nightmare with the last.

"To be avoided at all cost"

1.0 rating
Very Unsatisfied

We installed our first unit in 2009, a Trane XL16i, and after the first year the compressor unit had to be replaced. It was fully warranted parts and labor but ever since we had to have it verified. For the past two years when the pump starts up it make an impressive noise that even the technician cannot fix. We are stuck with it and since it still generates heat and cool air it will not be repaired by Trane. This unit came with a 10-year parts and labor guaranty. We hope that it will break so that Trane will have to replace it. In 2011 we bought a second unit, i.e., same model, but this time our installer did not informed us that there wasn't any guaranty of 10 years parts and labor. This unit had again a compressor that broke and had to be replaced. We had to pay $1,000.00 in labor cost and parts (Freon R410A and recuperation of Freon etc). We have only a 30 day warranty for the second unit. Overall I do not recommend Trane and a neighbor of ours had to replace their compressor after 3 years and had to pay labor costs.

"It's down again."

1.0 rating
Very Unsatisfied

Had a XL15i and the compressor went out within days after the 10 year warranty. Had many repeat problems over the years and got talked into a XL16i. And have had many problems. They told me the frog that got into the electronics and shorted everything out was an act of god and wouldn't warranty it. The line set was poorly installed and rubbed on a pier under the house. Told no warranty against workmanship. This morning it went down again. There are two Trane dealers in my area and both suck. Estimate over $13,000 in service calls over a 15-year period. Sorry, I cannot afford having a Trane. My new non-Trane dealer has done the last two service jobs and they are good. The problem is it's never the same problem. Never again will I own a Trane.

"Stay away from Trane"

1.0 rating
Very Unsatisfied

Had this unit installed 4 years ago. Nothing but problems from day 1. Unit works OK during AC mode, but heat mode is a disaster. Unit freezes up, I'm not talking about a little frost (I expect that) I mean this thing has solid frost/ice 1/4 – 1/2 inch for days. Defrost cycle will not kick in or will occasionally kick in, but will only melt part of the frost then won't kick back in and then the ice forms. Only melts away when the temperature rises above freezing. Replaced 2 defrost boards, moved the sensors, no help. Trane Technician came on a day when temperatures were well above freezing and no sign of frost/ice on unit and statede it checks out according to Trane standards! Can't get Trane to have someone check the unit when the problem is occurring. Now Trane refuses to do anything to help with the unit and I am stuck with a lemon. Stay away from Trane. Poor product and customer service.

One unhappy customer on complains of a costly repair to fix a coil failure in a 6-year old XL16i.

Some consumers, on the other hand, aren’t as complementary of the XL16i. Many folks on believe the efficiency numbers aren’t good enough for a high-end unit and would like to see high performance for the cost of the unit. Another unhappy customer on complains of costly repairs and multiple parts breaking.

A thread on reveals a discussion between a homeowner and two experts about the Trane XL16i for a home in North Carolina. The experts agree that the XL16i would not be the best heat pump for this homeowner. The contractors mention that the HSPF rating should be higher, and the unit is not compatible with Trane’s optional humidity-reducing equipment, which would be a bonus for this location. Both experts recommend the Trane XL15i in this situation.

A poster on asks about the Trane XL16i, as he is considering installing a new heat pump instead of repairing his old one. Once again, experts are concerned about the heating capacity for this particular heat pump. The location is Ohio, which has many cold days during the year. Here, the contractors recommend the Trane XL15i or another 14 to 15 SEER unit.

A recent post on is written by a potential Trane customer. He is considering the XL16i for his home in Florida. The experts mention the lack of humidity removal by the XL16i; one contractor suggests a variable-speed air handler or switching to the XL15i for better control of excessive humidity.
