What Are the Top Signs You Need Furnace Repair?

How Do You Troubleshoot Common Furnace Malfunctions?
Problem: Furnace unit is blowing cold air or failing to ignite on startup.
Solution: Cold supply air usually stems from a dirty flame sensor, tripped limit switch, or faulty hot surface igniter. Our technicians clean flame sensors and replace worn ignition controls on-site.
Problem: System turns on, runs for a few minutes, and shuts down repeatedly (short-cycling).
Solution: Short-cycling is frequently caused by restricted airflow from clogged air filters or an overheating heat exchanger. Replacing filters and clearing duct obstructions prevents heat exchanger damage.
Problem: Screeching, grinding, or loud metallic rattling sounds during operation.
Solution: High-pitched squealing indicates blower motor belt friction or bearing wear. Shut system power off immediately and call for repair to avoid total blower motor failure.
Problem: Burning odors or rotten-egg gas smells when the burner ignites.
Solution: A persistent burning smell signals heavy dust accumulation on electrical components, while a sulfur/gas smell indicates a gas leak. Evacuate immediately and contact emergency service.
