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.
