Common Heating Misconceptions Explained
One of the most persistent myths in home heating is that any strange noise coming from your furnace signals an expensive repair bill in your future. At Aeromark Mechanical, we regularly encounter worried homeowners who lose sleep over their heating system’s occasional pops and bangs.
Let’s break down this misconception:
Normal Furnace Sounds vs. Problematic Ones
Normal sounds include:
• Expansion and contraction noises
• Brief clicking when the system starts up
• Low humming from the blower motor
• Gentle whooshing of air
These natural operational sounds shouldn’t cause concern. However, some noises do warrant professional attention:
• Loud screeching or metallic grinding
• Constant banging or booming
• High-pitched whistling
• Persistent rattling
Why This Myth Persists
The belief that all furnace noises indicate major problems stems from outdated information about older heating systems. Modern furnaces are built with better materials and engineering, making them more resilient and quieter during operation.
The Truth About Maintenance
Regular maintenance, not panic over every noise, is the key to furnace longevity. Annual inspections can prevent most serious issues and help distinguish between normal operational sounds and genuine problems.
Remember, while some noises may indicate issues requiring attention, many are simply part of normal furnace operation. When in doubt, having a professional assessment is always wise, but don’t assume every sound means your wallet is about to take a hit.
Let Aeromark Mechanical’s experienced technicians help you understand your heating system better and maintain it properly for years of reliable service.
