Trane XR12 Central Air Conditioners | FurnaceCompare®

Trane XR12 Air Conditioner Overview

The Trane XR12 was a split-system, outdoor cooling unit capable of reaching up to 13 SEER. This now-discontinued line consists of 12 units ranging from 1.5 to 5 tons, with cooling capacities between 18,000 and 60,000 BTU/H. At the time of manufacture this series was offered with both R410A and R22 refrigerant options; today, R22 has been banned by the Environmental Protection Agency for use in new units.

The XR12 is promoted by the manufacturer for its durable performance, with full-side louvered panels finished with baked-on powder paint, corrosion-resistant WeatherGuard fasteners and a torture-tested spine fin outdoor coil. The fin coils are made of aluminum in order to further increase durability, reduce air resistance and maximize heat transfer. Additional features include a Climatuff compressor, which the manufacturer says is made to handle extreme operating conditions and thermal stress, and rust-resistant base pan.

Trane XR12 Air Conditioner Reviews

"Trane parts not made availble by Trane"

1.0 rating
Very Unsatisfied

Trane certified techs installed the system in 2004. No service manuals are readily available to the public. Trane will not sell parts to the public, but will send a service person. Trane information about systems and troubleshooting is withheld by Trane. Homeowners, even those with technical abilities, are denied access to information and parts to make routine repairs. I would not advise installing any Trane until this policy of obfuscation of information and parts from the homeowner is corrected. Manuals and parts should be readily available to the general public, to facilitate selection and maintenance of their HVAC system.

I need to buy supplies for this unit so I need to look inside this AC because my capacitor doesn't have a number. Please, I need your help. Thanks, I've already sent this AC to be to fixed 3 times.

"Very Satisfied"

The York air conditioner that the builder had used gave out during some of the hottest days of that summer. I contacted a local contractor, who sells Trane, and never did any research – I just wanted cool air, again. The only time I had a concern was when the XR12 was only two years old. One day, the unit attempted to start, but all I heard was a hum and it quit. It attempted to start three more times over several minutes, but wouldn't. I had to run errands and I thought about how this "two-year old" unit was already quitting on me. When I returned home, I was prepared to call the contractor and tell them what a piece of junk the XR12 was, but before I did, I walked over to the unit to see if there were any buttons I could push to make it do anything. The first thing I noticed, as I approached the unit, was the stench of something that had died. I don't want to make anyone queasy with further details, but this unit has the capacity to "puree" a black snake – one that hvac presumably wrapped itself around the motor housing to keep warm and had temporarily restricted the fan blades from turning. The XR12 responded appropriately for a stopped fan and didn't start, thus preventing extensive damage to the unit. Suffice to say, Trane earned my respect. I now plan to replace my old York furnace and simultaneously purchase a new, matched A/C unit with greater efficiency than the XR12. I will strongly consider the line of equipment by Trane in this next purchase.

"You might have Chinese Drywall!!"

3.0 rating

My daughter had a home built just a few years ago. After the lower and upper AC coils both leaked 3 times over, they found out they had Chinese Drywall. The fumes from the drywall destroys copper, etc, thus the leaks. So before you blame the AC manufacturer, check online for the signs that you might have Chinese Drywall. I feel so sorry for you if you do, but better to find out and get your family out of that environment as soon as possible.

Question and Answer


I have a Trane XR12, is it a heat pump or just air conditioning?


On 2014-12-03 Danielle wrote:

The Trane XR12 is both an air conditioner and heat pump. To determine which one you have is from the model number. If the model number starts with a ‘2TTR’ or ‘4TTR’ then the unit is just an air conditioner, but if the model number begins with a ‘2TWR’ or ‘4TWR’ then it is a heat pump.
