5 Signs Your Furnace Needs Professional Attention

1. Yellow or Flickering Pilot Light

A healthy pilot light burns blue. If yours is yellow or flickering, it could indicate:

• Improper combustion
• Carbon monoxide production
• Ventilation issues

Action: Turn off the furnace and call a technician immediately.

2. Strange Noises

Some sounds to watch for:

• Banging: Could be delayed ignition or ductwork issues
• Squealing: Belt or bearing problems
• Rumbling: Burner issues
• Clicking: Ignition problems

3. Uneven Heating

If some rooms are warm while others are cold:

• Check that vents are open
• Replace your air filter
• If problem persists, call for inspection

4. Increased Energy Bills

A sudden spike in heating costs often means:

• Your furnace is working harder than it should
• Components are wearing out
• Ductwork may be leaking

5. Frequent Cycling

If your furnace turns on and off constantly:

• Thermostat may be malfunctioning
• Airflow could be restricted
• Heat exchanger might be overheating
