Frequently Asked Questions about Furnace Repair

Having problems with your heating system? Get answers to common questions about furnace repair so you can make informed decisions.

Why is my furnace blowing cold air?

Several problems can cause your furnace to blow cold air::

Pilot light or ignition problems: If the pilot light is out, the burners won't light, and the furnace won't produce heat. In newer furnaces, a faulty electronic ignition system can prevent the burners from igniting.
Thermostat issues: An incorrectly set or malfunctioning thermostat can prevent the furnace from turning on or cause it to blow cold air. Check that your thermostat is set correctly and is sending a signal to the furnace to turn on.
Overheating: If the furnace overheats, a safety switch may shut off the burners, causing the blower to circulate cold air.. This is typically caused by a restricted airflow, often due to a dirty air filter.
Ductwork problems: Seal any ductwork leaks to improve performance. This can also result in the furnace blowing cold air, especially if the leak is near the beginning of the ductwork run.
