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 Americas Most Trusted HVAC Brand study for years 2015, 2016, 2017, 2018 & 2019. Your experiences may vary.
