## Why do I need indoor and outdoor model numbers?

Performance belongs to a specified combination of components. Ask for the exact indoor/outdoor match and applicable certification record, rather than assuming every coil or air handler with the same brand delivers the advertised rating.

## Use the certificate as evidence, not a recommendation

The AHRI Directory provides certified product-performance information. Match identifiers carefully, including relevant model suffixes and blower or coil details. A family brochure can show a rating that belongs to a different indoor combination. [1]

## Know what the record does not prove

A directory entry does not establish local stock, installed price, compatibility with every existing furnace, permit approval or fitness for your house. It also does not replace manufacturer expanded performance data at your actual design conditions. [2]

## Handle equipment changes explicitly

Write the proposed components into the quote and request documentation for any substitution. Before final acceptance, compare the installed nameplates with the approved list. Keep the certificate with commissioning and warranty records so later service has a consistent equipment identity.

## Decision exercise

Use a comparison sheet with fields for outdoor model, indoor coil, air handler or furnace, controls, AHRI reference and certification status. If Bid A supplies all fields and Bid B lists only a brand and tonnage, request the missing information before treating the price difference as equivalent value.

Numbers are illustrative assumptions, not forecasts.

## Preparation checklist

- Photograph model labels without exposing account details.
- Check exact combination identifiers in the official directory.
- Keep certification distinct from in-stock availability.

## Does SAVPWR’s equipment catalog mean the products are in stock?

No. Catalog records support research and comparison; they do not represent inventory, an installed offer or a verified fit for the home.
