Common Furnace Myths Exposed
One of the most persistent myths in the HVAC industry is that a noisy furnace automatically means you’re facing an expensive repair bill. At Advantage Service Co, we regularly encounter worried homeowners who lose sleep over their heating system’s normal operational sounds.
Let’s break down this misconception:
Normal Furnace Sounds vs. Problem Indicators
• Expansion and contraction noises (normal)
• Initial startup sounds (normal)
• Gentle humming from the blower (normal)
• Metallic banging or screaming sounds (requires attention)
Many homeowners in North Little Rock and Sherwood misinterpret these regular operational sounds as signs of impending doom. While certain noises definitely warrant professional attention, not every bump or whisper from your heating system signals trouble.
The Truth About Furnace Sounds
Most modern furnaces are designed to make some noise during operation. The key is recognizing the difference between normal operational sounds and genuine warning signals. During our service calls throughout Little Rock, we often reassure customers that their concerns, while valid, are simply part of normal furnace operation.
When to Take Action
If you hear:
• Metal-on-metal scraping
• High-pitched whistling
• Loud booming on startup
These sounds deserve immediate professional attention. However, don’t assume the worst – sometimes the fix is as simple as tightening a loose panel or replacing a basic component.
Remember, regular maintenance from qualified HVAC contractors remains your best defense against major furnace issues, noisy or otherwise. Prevention is always more cost-effective than emergency repairs.
