Product names, availability and specifications can change. Confirm the exact model and latest dated document before signing.

Proposal checklist

Six fields to normalize.

Do not compare a premium matched system against an entry-level equipment-only price as if the scopes were equal.

01

Exact model

Record indoor and outdoor model numbers, capacity and matched-system references.

02

Installed scope

Separate equipment from labor, permits, electrical work, controls, accessories and commissioning.

03

Efficiency

Compare the metric and test basis appropriate to the system, including SEER2, EER2, HSPF2, AFUE, UEF or solar production assumptions.

04

Warranty

Separate manufacturer parts coverage, registration requirements and contractor labor coverage.

05

Local support

Confirm qualified installation, service coverage, parts access and escalation routes in your area.

06

Whole cost

Compare cash and financed price, energy, maintenance and likely repairs over 5 and 10 years.

Contractor interview

Three questions to ask in writing.

Manufacturer coverage and contractor labor responsibility are different commitments.

01Product identity

Which exact A. O. Smith model numbers and matched components are included, and where are their current performance certificates?

02Installer responsibility

Which parts of the A. O. Smith warranty require registration, qualified installation or documented maintenance, and who completes them?

03Local ownership

Who provides labor coverage, routine service and parts support locally if the system needs attention after installation?

Relevant project paths

Compare the system before the brand.

Start with home fit and installation scope, then evaluate exact models.

COMPARE COMPLETE COST

Brand inclusion is not a ranking or endorsement.

Verify current product data, contractor scope and five- or ten-year ownership assumptions.
