Trane High-Efficiency Heating Systems
The ultimate in comfort
All winter long, you depend on your furnace to meet the heating needs of your family and home. That's why we build Trane gas and oil furnaces to perform again and again, year after year.
Beyond performance, we also provide options for energy-efficient operation. In fact, some of our furnaces operate at over 95% efficiency, which means that 95% of the fuel you pay for is actually converted into heat for your home. Take a look at the furnaces below and experience the Trane difference.

Maximum Comfort with efficiency in mind. With innovative technology and quality materials, Trane 80 furnaces will remain durable, efficient, and cost effective far into the future. Each Trane 80 furnace functions at 80% efficiency, so that 80% of the fuel you pay for is turned into heat for your home. This AFUE (annual fuel utilization efficiency) rating exceeds the federal government requirement of 78% for new furnaces.
The Trane XL80 a two-stage* heating system featuring a four-speed blower motor for ideal comfort in the transitional seasons and at the height of winter.
The Trane XV80 is a two-stage* heating heating system featuring a variable-speed motor with Comfort-R™ that operates at lower, more efficient speeds than conventional blower motors and provides greater humidity control during cooling. What's more, the XV80 features a high-efficiency motor and continuous fan mode that make every energy dollar really count, and a cleanable filter.
The Trane XC80 offers the added peace of mind of ComfortLink II Communicating Technology, which gives you the ability to monitor and control your comfort settings remotely by phone. So you can count on a warm, comfortable air even when the weather is brutally cold outside.
*Two-stage furnaces do not frequently stop and start, typically running at the first stage (65% of capacity) up to 80% of the time. This provides for quieter operation and consistent, even heating since it runs longer at the lowest, energy-saving level. When more heat is needed, the second stage is called upon for added comfort. Plus, after the heating cycle, two-stage furnaces continue to run for a few moments to make sure the heat left in the exchanger is used to warm your home.
