Trane has more than 120 years of experience in the business. They don't just build products – they own patents on them. And they don't just test products – they push them to the extreme. If a Trane product can't make it through torturous testing, you'll never see it in your home. It’s that kind of reliability that’s earned them America’s Most Trusted HVAC System, three years in a row by Lifestory Research.
