Trane makes high-performance central air conditioning units that can maintain a comfortable temperature in your home, no matter the weather. Its systems are environmentally friendly, with durable designs that stand up against the elements. And with SEER ratings as high as 22, they’re some of the most energy efficient central AC units available.

With their TruComfort features, Trane’s units are designed to reduce humidity – they have longer run times at lower speeds than other central ACs, which removes more moisture from the air. Older air conditioners often shut all the way off, leaving a big window of time for the air to get sticky again before they kick back on.

Trane’s central air conditioners have an average SEER rating of 17.3, which makes the brand the third most efficient one we reviewed, behind Lennox and Amana. By comparison, the industry average SEER is 16.7. The higher the SEER number, the more energy efficient the AC unit is – an air conditioner with a rating of 22 SEER can save you money on your electrical bills.

These air conditioners have aluminum coils that incorporate fins, which enhance airflow and resist corrosion and leaks better than the copper coils of the past. Trane’s ACs also use R-410A refrigerant, which is environmentally friendly and doesn’t harm the ozone layer.

During our research, we found that Trane's current offerings have an average sound output of 70.1 decibels, making it the second quietest brand we reviewed. In fact, the company's loudest models register at 72 decibels, which is only slightly louder than the industry average of 71.25 decibels.

Trane air conditioning systems feature ComfortLink II communication technology, so you can use a compatible thermostat to configure and calibrate the equipment to ensure it performs at its best, and it even allows you to control your home’s temperature from your smartphone. However, you have to pay a monthly subscription to enjoy some advanced features.

The company’s XR series central air conditioners have a 10-year warranty, and its XL and XV series models are covered for 12 years, provided you register them within 60 days of installation. There is also a 10-year warranty on the outdoor coil and other internal parts. Trane’s warranties are shorter than the lifetime warranties some brands offer, but 10 years is standard across the industry. If you fail to register your Trane AC unit after purchase, the compressor and parts warranties only last five years.
