Everybody knows it’s hard to stop a Trane. But not everybody knows why.

There’s only one way make sure your product is tougher than anything.

And that’s to test it against everything. Which is why Trane’s team of engineers and quality technicians run their products through the gauntlet, drenching them with rain, pounding them with heat, and pummeling them with high-speed impact.

And sure, most homeowners will never need their HVAC systems to go from below freezing one day to 150° the next. But these torture tests prove an important point: If a product can stand up to Trane testing, it can stand up to anything.
