"We have been satisfied so far!"

We had to replace 15 yr old Trane unit and air handler 2 yrs ago. We used the local Trane dealer to install the XL16i unit. So far, no complaints. In fact our other air handler is dying right now, so we are looking at replacing that 17 yr old air handler and 6 yr old 10 seer pump with a new 15 or 16 seer Trane. I believe the installers can make a big difference. Make sure your lines are new or get flushed out from the old 22 refrigerant to the new 410!

This is a reply to r davis… Sounds like your problem needs to be taken up with the contractor not TRANE. If you would have had a Trane comfort specialist install the system they would have known that the XL16i CAN'T be used with zoning. If installed properly your energy bills will be lower. My advice is to call the Trane Comfort Specialist that you passed up because they were too much money and have them tell you what is wrong with the install.

3 year old 16xi with zonal system and clean effects air filter($22,000). Salesman told us this was the "state of the art" in comfort and efficency. Our heating bills have tripled from our last house that had a $5000 rheem system. We have had the installers techs out 10 times in the last 3 years. They have replaced the computer board, the main compressor twice and the clean effects air filter once. Our heating bills are still outragous. We have just open a case with the washington state attorney generals office.

"Trane is the best"

I am an independent HVAC contractor in Portsmouth, VA. And I have the opportunity to sell any brand a/c units I want. In our industry when units break down after we install them the manufacturers do not pay us to fix them. Therefore, it's in our best interest to sell ones that do not have problems. I installed a XL16i heap pump in my personal house 3 years ago and it exceeded even my expectations and we sell hundreds of these systems every year, so it takes a lot. Trane is by far the best brand but if it's installed improperly it's not going to work. The installation is even more important than the brand you buy. Unfortunately it's a proven statistic that 90% of the systems that have been installed since the mid 1990's are installed improperly. That will explain why some people on this site are very happy and most are not. (Also people tend to complain more than they commend) Trane has its share of problems ( anything that is made by man does) but I can assure anyone that they are far fewer than any other brand. Do you homework on the contractor you are going to do business with. Check the BBB, check references, check their customer satisfaction score through Trane. And last, remember the cheapest contractor is almost never the best. Thank you, and take my word for it Trane is the best unit built.

After 15 years my 80% efficient York heat pumps gave up and I replaced the small unit with another York since I had replaced the outside compressor unis a year earlier. The 3.5 ton unit was replaced with a Trane XL16i unit that was supposed to save me 30% on my electric bill. The new high effeciency Trane XL16i unit runs constantly and the outside unit has been frozen up numerous times. The technician came out yesterday for the third time in three weeks and stated that it was normal for the outside coils to be totally frosted over with one inch of ice. (He replaced the defrost board and sensor two weeks ago to get the frost to melt.) Two weeks ago I got a $575 electric bill (highest ever) thanks to my new high efficiency Trane heat pump.

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.
