Trane XL20i Air Conditioner Overview

The Trane XL20i high-efficiency air conditioning unit offers up to 20 SEER performance. This model uses dual compressors to maximize efficiency by consistently operating with the smaller compressor and only using the larger component when the system detects a drastic change in temperature.

According to the manufacturer, the XL20i boasts consistent, quiet operation due to an adjustable fan motor and compressor sound insulator designed to minimize noise. Additional components, including galvanized steel cabinets, a rustproof basepan, zinc-coated fasteners and a powder-paint finish, contribute to the unit’s durability.

This series also is equipped with Trane’s ComfortLink II system, which controls communication between components and can be used to automatically charge, configure and calibrate the unit.

Unit breaks down every 3-4 weeks usually on weekends or holidays. Is about three years old. Both compressors replaced as well as a few other parts, overflow valve and some auto suction safety shut off. In reading reviews it seems Trane knows of these recurring issues but choose to do nothing about it. I generally have to power down unit then turn back on and it might work. All you pay for with a Trane is the name with crappy a/cs that break down with regularity. I encourage you to not be snowed by their ads…look elsewhere. You will save money and be much happier with another more dependable brand.

Two units for two years $25000 later, never been without a service call or expense. We had a better luck with our 20 years old Tempstar, We are sweating now while waiting for a command board and motor.?? We were told we are buying the best with least problems… Wrong.!

This is my fourth Trane ac system in 28 years. Live in south Florida so bought the XL20i to help with humidity removal. Have had the unit for twenty months. The compressor motor died and the ac tech had a very difficult time finding a new motor. He found one someplace in the state and I was told that I would have to pay for shipping in order to get it in a couple of days. Otherwise I'd have to wait weeks. I called Trane customer service and the rep told me that other people have complained about parts not being available for weeks. I have never had an issue with the other three units. I will never buy Trane again and would advise consumers to stay away from Trane.

"Trane is off the tracks, running amuck"

I bought two XL20i units five years ago. The first floor unit has never had an issue. The second floor unit has had over 20 service calls resulting in replacement of the air handler, several thermostats, indoor and outdoor circuit boards and 5 visits by the local distributor. The system is unreliable and seems to fail whenever the outdoor temp/humidity rise, I.E. whenever we need it to work. Our installer has been great and has offered to replace the whole system with a comparable Lennox unit. We are definitely taking them up on the offer. You can stop a Trane……just try to turn it on and get it to cool. Class action? Count me in!!!!
