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.

"Poor experience"

1.0 rating
Very Unsatisfied

Entire Trane heat and ac installed 9 years ago. In spite of all proper maintenance, have experienced 2 total system failures in past 2 years. Out of pocket costs– while under parts warranty — still exceeding $2,000 for uncovered labor and refrigerant. Also, latest failure was a coil, and after 2 weeks still unable for HVAC local installer to receive the needed replacement coil from Trane. Under no circumstances should anyone buy this high priced system. Quality is poor, service is worse.

"Poor quality control; labor warranty loopholes"

4.0 rating
Somewhat Satisfied

My trane system needed 2 new compressors and a new coil within 6 years of installation. To make it worse, installing dealer couldn't diagnose the need for replacements and labor warranty loopholes socked me with cost to replace defective units! Cost me $4000 extra in labor because they wouldn't honor their labor warranty! Stay away from Trane.

"They say you can't STOP a Trane. Mine literally did!"

1.0 rating
Very Unsatisfied

The energy saving are nice, but they've never been able to dial in the humidity setting and my compressor failed in year 2 so even though I had a parts warranty the dealer charged my another $1,000 in labor after I just gave them $15,000 for the initial install. Frustrating that I'm already sinking money back into this system so soon…. And I would absolutely not invest back into this company!

"No parts on one year old unit"

1.0 rating
Very Unsatisfied

We purchased two top of the line ah and condenser systems from Trane in 2016. Last month, the main circuit board in our ah stopped working. In July in Florida, no ac for five days. We were told by our contractor that Trane had stopped making that ah right after we bought them. They had to scramble for parts all over the country at other dealers to find one for us. What happens next time??? I called Trane and sent up forms with absolutely no follow up or help. I'd strongly recommend against buying Trane products

Purchased XL20i Heat Pump in 2013. One week after installation, the unit stopped cooling due to lack of refrigerant. A bad weld on a manufacturing nipple on the condenser coil was found to be leaking and was welded. Promised efficiency and 20% reduction is electrical consumption was never realized. Actual savings was between 8 and 10%. Four years later, the unit again stops cooling due to loss of refrigerant. Again, the condenser coil is leaking. New coil installation cost $600 labor, which is not covered by the manufacturer's warranty. After 25 years and three Trane units, I will not buy another Trane.
