A furnace replacement looks simple — same spot, new box — but fuel type, efficiency, staging and airflow decide how the new one actually performs. A complete proposal explains those choices instead of quoting a tonnage and a price.

What to think about first

Fuel and efficiency: single-stage, two-stage and modulating furnaces, and what AFUE means for your gas bill.
Airflow: blower type and whether your existing ducts can deliver the air the furnace needs.
Venting: high-efficiency furnaces vent differently — the proposal should say how.
Matched equipment: if you have or plan AC or a heat pump, the furnace and coil should be selected as a system.
Comfort issues first: hot/cold rooms are often duct or airflow problems a new furnace alone won't fix.

What a complete proposal should state

Exact model. Manufacturer, model number, capacity and AFUE.
Sizing basis. How capacity was determined — load calculation, not just the old unit's size.
Venting & gas. Venting plan, gas line work and permits stated.
Duct connection. Transitions, return air and any duct modifications included.
Startup. Gas pressure, temperature rise and safety checks at commissioning.
Warranties. Heat exchanger, parts and labor terms, in writing.
