Igniter or flame sensor?
If burners light for a few seconds and then shut off, the problem is more often a dirty flame sensor, which costs $80 to $250 to clean or replace. If burners never light, the igniter is the likely culprit. Hot surface igniters typically last 3 to 7 years.
How to get a fair quote
- Get at least three written quotes that list the brand, model number, size (tons or BTU) and efficiency rating.
- Ask whether the price includes permits, removal of the old unit, refrigerant, a new thermostat and any duct or electrical work.
- Ask for a load calculation (Manual J) instead of matching the old unit's size by default.
- Compare labor warranties (1 to 10 years) as well as the manufacturer's parts warranty, and register the equipment.
- Schedule non-urgent work in spring or fall, when contractors are less busy and more willing to discount.
