A new furnace or air conditioner should be sized for your house. Ask whether the contractor runs a load calculation (often called Manual J) or sizes by the old unit.
Ask for a written quote that lists the model numbers, the removal of the old unit, the permit and any duct or electrical work.
Many equipment warranties need registration within a set time after install. Ask who registers it.
Ask what a tune-up includes. A furnace check before winter is common in Michigan.
