The warranty for a Trane air conditioner varies based on the make, model and part of the air conditioner. The warranty also varies based on whether the air conditioner is registered with Trane.
If the Trane air conditioner is not registered, some or all parts are covered for shorter period of time. A registered Trane air conditioner has a longer limited warranty. Some air conditioner parts are covered for longer or shorter periods of time.
A licensed HVAC professional must perform routine service and maintenance on the Trane air conditioner. If the air conditioner is not properly maintained, it voids the warranty.
