Trane has more than 120 years of experience in the business. We don't just build our products – we own patents on them. And we don't just test our products – we push them to the extreme. If our 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 us America’s Most Trusted HVAC System*, three years in a row by Lifestory Research.
