Common Furnace Myths Exposed
One of the most persistent myths in home heating is that any unusual noise coming from your furnace automatically signals an expensive repair on the horizon. At Holt Plumbing and Heating, we regularly encounter worried homeowners throughout Des Moines and West Des Moines who lose sleep over every ping and pop their heating system makes.
Let’s break down the truth about furnace noises:
Normal Furnace Sounds vs. Concerning Ones
Normal sounds include:
• Light expansion and contraction noises
• Gentle humming from the blower
• Soft clicking when starting up or shutting down
• Quiet whooshing of air through vents
Sounds that do warrant professional attention:
• Loud banging or booming
• Persistent squealing
• Metal-on-metal scraping
• Continuous rattling
The Science Behind Common Furnace Noises
Most heating systems make some noise during regular operation. As your ductwork warms up and cools down, the metal naturally expands and contracts, creating those familiar pops and creaks. This is particularly common in homes throughout Urbandale, Clive, and Johnston, where temperature fluctuations can be significant.
Prevention Is Key
Regular maintenance remains the best way to prevent both minor and major issues. Annual inspections can:
• Identify potential problems early
• Ensure efficient operation
• Extend system lifespan
• Maintain manufacturer warranties
• Reduce energy costs
Remember, while not every noise signals impending doom, it’s always wise to have unfamiliar sounds checked by professionals. Serving communities from Norwalk to Johnston, we’re here to help distinguish between normal operation sounds and those requiring attention.
Don’t let myths about heating system noises cause unnecessary stress. When in doubt, reach out to a qualified professional who can properly diagnose any concerns and provide peace of mind.
