Safety boundary: Warranty terms change by model and seller. Read the actual documents rather than relying on a sales summary.
Parts warranties
Manufacturer coverage may require registration, owner occupancy, installation by qualified contractors and maintenance records.
Labour coverage
Labour is often provided by the installing contractor for a shorter period. Confirm travel, diagnostic and after-hours charges.
Major components
Heat exchangers, compressors and tanks may have separate terms, prorating or replacement-only coverage.
Transfer and resale
Ask whether coverage transfers to a new owner and what documentation is required. Store invoices and serial numbers somewhere accessible.
Useful questions to record
- Is the scope written and comparable?
- Who obtains permits and performs specialized work?
- What testing, commissioning and documentation are included?
