Why Your Furnace Making Noise Doesn’t Always Mean Expensive Repairs

Many homeowners panic when they hear unusual sounds coming from their heating system. At Eastside Heating & Air Conditioning, Inc., we regularly encounter worried customers who assume the worst when their furnace starts making noise. Let’s debunk one of the most common myths in home heating:

The Myth: All Furnace Noises Signal Major Problems

This simply isn’t true. While some sounds certainly warrant immediate attention, not every heating system noise indicates an expensive repair is needed.

Common harmless noises include:
• Expansion and contraction sounds as ductwork warms up
• Brief pops when the system starts
• Light humming from the blower motor
• Gentle whistling from air filters

However, these sounds should prompt a service call:
• Loud banging or clanking
• Persistent squealing
• Rumbling after the blower turns off
• Grinding metal sounds

The Truth About Furnace Noises

Many noises can be resolved through simple maintenance:
1. Regular filter changes
2. Annual professional inspections
3. Ductwork cleaning
4. Lubrication of moving parts

Serving Brighton, Northglenn, Broomfield, Commerce City, Stapleton, and Derby, CO, we encourage homeowners to schedule routine maintenance rather than waiting until small issues become major problems.

Remember: Being proactive about furnace maintenance typically costs far less than emergency repairs. If you’re unsure about a noise your system is making, it’s always better to have it checked by a professional than to ignore potential warning signs.
