Quick Warranty Facts
Registered vs. Unregistered: The Rule That Decides Everything
Bosch 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 Bosch 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 Bosch 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 the Bosch Warranty Covers
| Component | Registered Coverage | Notes |
|---|---|---|
| Functional parts | 10 years | Drops to 5 years without on-time registration |
| Compressor (AC / heat pump) | 10 years | Same registration rules apply |
| Heat exchanger (gas furnace) | Varies by model | Check your model's certificate for exact terms |
| Labor | Not included | Labor is covered only by your installer's own guarantee or a separately purchased labor plan |
| Refrigerant, filters, maintenance | Not included | Consumables and routine service are the owner's responsibility |
Terms shown are Bosch's most common current residential terms as of July 2026. Older units and specific product lines can differ, so always confirm your exact coverage with the serial number using the official lookup above.
What Happens When the Home Is Sold
Yes. Bosch's warranty stays with the unit as long as it remains at its original installation site, so the remaining coverage carries over to a new homeowner without a transfer fee.
Bosch Warranty FAQs
How long is the Bosch HVAC warranty?
Bosch covers functional parts for 10 years when the unit is registered within 60 days of installation. Without registration, coverage drops to 5 years.
Do I need to register my Bosch 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 Bosch warranty transferable to a new homeowner?
Yes. Bosch's warranty stays with the unit as long as it remains at its original installation site, so the remaining coverage carries over to a new homeowner without a transfer fee.
How do I check my Bosch 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 Bosch'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 Bosch warranty cover labor costs?
No. Like nearly every HVAC manufacturer warranty, Bosch'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.
