Variable Speed. Trane created it, then perfected it.

Variable speed is not new technology for Trane. It’s technology perfected. Trane was the first in the industry to apply variable speed technology to residential air conditioning. Now Trane brings variable speed technology to the next level, with a system that intuitively adjusts to changing heating and cooling needs, working only as hard as it has to and often at lower, more efficient and quieter speeds.

It all started over a hundred years ago, when Reuben and James Trane made the decision to stand out from the crowd. To build a comfort system like no other, using uncompromising quality, innovation and reliability. Today, their legacy is found in everything Trane makes, from our premium materials to our industry leading technology to our extensive product testing under the harshest conditions. When you buy a Trane, you’re buying a commitment from us, to you. A commitment to your total comfort, and your total peace of mind. Because that’s what Reuben and James would have done.

these kind of extremes, we believe in taking 
extraordinary measures to ensure the reliability of a Trane. 


More Stages Mean More Comfort and Efficiency 

Staging refers to an air conditioner’s or heat pump’s ability to run at less than its maximum capacity in order to increase comfort levels and boost efficiency. For example, two-stage systems offer better comfort and higher efficiency than single-stage systems, while Trane’s TruComfort™ variable speed system, with 700 to 750 stages, offers maximum comfort with the highest efficiency. 

What does “Stage of Comfort” really mean?

Sometimes you just feel “too hot” or “too cold” between cycles of your system. Having 700/750 stages nearly eliminates temperature fluctuations. Your system glides along as if on cruise control, barely sipping electricity for much of the day. It also runs at lower speeds for longer periods of time offering:

• Advanced temperature control

• Lower humidity

• Reduced sound

• Enhanced filtration

• Lowest cost per minute 

The higher the system SEER and HSPF ratings, the more comfort you will get from each energy dollar.


Understanding the ratings. Different ratings measure the efficiency of specific types of heating/cooling systems. Here’s what you need to know.

• SEER (Seasonal Energy Efficiency Ratio) measures air conditioning and heat pump cooling efficiency.

• HSPF (Heating Seasonal Performance Factor) measures the efficiency of a heat pump. 

Nexia displaysTrane TruComfort systems work seamlessly with the Nexia™ smart home system and Trane’s Nexia-enabled controls, allowing you to manage your home’s heating and cooling remotely via any web-enabled smartphone, tablet or computer. In addition to climate control, Nexia can be expanded to include remote management of locks, video surveillance, lights, shades, garage doors, energy usage, and more, from wherever life takes you.
