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
