Every Trane is tested to withstand the harshest conditions nature or our engineers can throw at it – like freezing conditions in our System Extreme Environmental Test (SEET) lab or five-inches of water an hour in our Climate Chamber. That's how we get heating and cooling systems you can count on to run through anything. And when it's time for a tune-up, our dealers and Trane Comfort Specialists™ are always at your service right when you need them. It's that kind of reliability that's earned us the honor of America's Most Trusted® HVAC System†. †Trane received the highest numerical score in the proprietary Lifestory Research 2019 America’s Most Trusted® HVAC Brand study for years 2015, 2016, 2017, 2018 & 2019.
