Quick Warranty Facts
Registered vs. Unregistered: The Rule That Decides Everything
Trane publishes two very different parts warranties, and which one you get depends on a single piece of paperwork. Register the unit within 60 days of installation and parts are covered for 10 years. Skip registration and coverage drops to the base term of 5 years.
The clock runs from the installation date, not the manufacture date. If you cannot prove the install date with paperwork, manufacturers typically fall back to the manufacture date plus a grace period, which is one more reason to keep your installer's invoice.
Bought a home with a Trane system already installed? The registration window has almost certainly passed, and the coverage that remains depends on the transfer rules below. Your first step is confirming when the unit was actually made.
Step one for any warranty claim: confirm your unit's age
Every Trane warranty window is measured in years from installation, so the manufacture date on the data plate is your anchor. Enter the serial number and we will decode the exact manufacture date free, so you know whether you are inside the 5-year or 10-year window before you call anyone.

What Happens When the Home Is Sold
Yes, Trane allows the warranty to transfer to a new homeowner, but a transfer application and fee must be filed shortly after the home sale. If the fee is not paid, coverage typically drops to the shorter base term.

Trane Warranty FAQs
How long is the Trane HVAC warranty?
Trane covers functional parts for 10 years when the unit is registered within 60 days of installation. Without registration, coverage drops to 5 years. The compressor carries its own 12-year term. Gas furnace heat exchangers are covered for 20 years, with lifetime coverage on premium furnaces.
Do I need to register my Trane unit to get the full warranty?
Yes. Registration within 60 days of installation is what unlocks the full 10-year parts term. Miss the window and the unit stays at the 5-year base coverage. Registration is free and takes a few minutes online with the model and serial number.
Is the Trane warranty transferable to a new homeowner?
Yes, Trane allows the warranty to transfer to a new homeowner, but a transfer application and fee must be filed shortly after the home sale. If the fee is not paid, coverage typically drops to the shorter base term.
How do I check my Trane warranty status?
You need the serial number from the unit's data plate. First decode the serial with our free lookup to confirm the manufacture date, then enter it on Trane's official warranty lookup to see the exact coverage on file. If the original owner registered the unit, the registered terms will show; otherwise the base terms apply.
Does the Trane warranty cover labor costs?
No. Like nearly every HVAC manufacturer warranty, Trane's coverage pays for replacement parts only. The labor to diagnose the failure and install the part is billed separately, and on major repairs labor is often the larger share of the bill. Labor is covered only if your installing contractor offered a labor guarantee or you purchased an extended labor plan.
