Keep the proposal, model and serial numbers, registration confirmation, invoices, startup records, maintenance history, and written workmanship terms together. Manufacturer parts coverage and contractor workmanship coverage are separate, and the written conditions control each claim.
Keep the two warranties separate
The manufacturer sets equipment parts coverage. S&S’s standard workmanship coverage is one year for installation and 90 days for repairs unless a different written term applies. The costs and conditions covered are not identical.
Registration matters
S&S’s terms describe common ten-year registered parts coverage and shorter, often five-year, base coverage. The manufacturer’s actual document controls. Confirm that registration was completed and save the confirmation.
Maintenance matters too
Failure to maintain the unit according to the manufacturer’s instructions may void its five- or ten-year factory warranty coverage. Retain professional service records. S&S’s labor terms require documented annual professional maintenance; club enrollment satisfies that maintenance requirement.
Ask before authorizing outside warranty work
Contact S&S to request workmanship service. The terms address work performed by another contractor without prior written authorization. Read the coverage page and request the full agreement if you need to check your specific situation.
Build an equipment folder that answers the coverage questions
Save a separate record for each indoor and outdoor component, including model, serial number, installation date and warranty certificate. Retain the registration confirmation rather than assuming a submitted form completed the process. The certificate for the actual equipment and ownership circumstances controls.
Comfortmaker’s published warranty page illustrates why specifics matter: it describes timely-registration conditions, an original-owner benefit and exceptions for some jurisdictions. That example is not a universal rule for every brand or every system. Ask which certificate applies to yours and which parts, labor and other charges remain outside coverage.
- Equipment identifiers and the applicable warranty certificates.
- Installation invoice and registration confirmation.
- Professional maintenance dates, findings and invoices.
- Repair approvals and records of components replaced.
