Symptoms Worth a Service Call

Cold air coming out of the vents
The burners light, then shut off a few seconds later
Banging, squealing or rattling from the furnace
The blower won't stop running
A yellow or flickering flame instead of a steady blue one
The thermostat calls for heat and nothing happens

What Moves the Price

The diagnostic or service call fee
Which part failed: a flame sensor costs far less than a control board or blower motor
Night, weekend or holiday rates
Whether the part is still under the manufacturer warranty
The furnace's age and brand, which affect parts availability

Common Questions

What is the most common furnace repair?

Cleaning a dirty flame sensor or replacing a cracked hot-surface ignitor. They're also two of the cheapest repairs.

Should I repair or replace my furnace?

Here's a rule many techs use: multiply the furnace's age by the repair quote. If the number is over $5,000, replacing it usually makes more sense.
