Bottom line

The Trane XL20i is Trane's top-of-the-line central air conditioner, with a seasonal energy efficiency ratio (SEER) of up to 20 and a Comfort-R feature that's great for controlling humidity. However, it's unclear whether its SEER is high enough to qualify for the Energy Star tax credit. On the plus side, Trane has a strong reputation for reliability, and this unit has a better-than-average warranty.


Unclear information from manufacturer. Sites like and praise the Trane XL20i for its seasonal energy efficiency ratio (SEER), which can reach 20, depending on conditions. This level of efficiency can save you money, according to Cecilia Harsch of However, it's unclear whether this unit also has the energy efficiency ratio (EER) needed to be Energy Star-compliant.

After inquiring with Trane, we were told that the XL20i is Energy Star-compliant "in most cases," but the rating depends on what other equipment is connected to it. The customer service rep was unable to tell us how loud the unit is, advising us to contact a local dealer for "technical information" like decibel level. The Trane XL20i does have one feature that multiple sources praise: Comfort-R technology that runs the fan at a slower speed during startup, which controls humidity better.

Pricing and rebates

Pricing is puzzling. Like most central air conditioner manufacturers, Trane doesn't disclose the exact price of its units. We found estimates for the Trane XL20i at and, based on reports from owners and contractors, but their figures differed widely. Moreover, this air conditioner may qualify for an Energy Star rating, depending on how it's installed. This means that it may not qualify for the $300 federal tax rebate on Energy Star-rated central air conditioning units that are installed through the end of 2013. To be sure, contact a local dealer to find out how much this unit will cost you and what rebates, if any, it's eligible for.

Maintenance and repair

Strong reliability record. We found no details about the repair record of this specific unit, but Trane air conditioners in general have a reputation for durability. The editors of say that Trane 'leads the industry in reliability,' and reports that Trane's products 'have a reputation of lasting the longest and being built the toughest.' In a survey of more than 40,000 homeowners with central air conditioning systems, Trane had one of the lowest repair rates, with 12 percent of all units needing repair during a five-year period. The warranty on the Trane XL20i is also better than average: When registered within 60 days of purchase, the compressor is covered for 12 years, and other parts are covered for 10 years. The warranty does not cover labor costs, but users can buy an extended warranty that does.
