Read the written terms
Check what components and repair locations are covered, what triggers service, and what is excluded.
Transferability
If transfer matters, verify the process, timing, fees, and whether future owners must register the warranty.
Company continuity
Warranty value also depends on the issuing company's ability to honor it. Keep original documents and contact information.
Maintenance conditions
Some warranties include homeowner responsibilities involving drainage, plumbing, landscaping, or other site conditions. Read those terms before assuming coverage.
