Debunking a Common Furnace Maintenance Myth
When it comes to maintaining your home’s heating system, there’s no shortage of advice floating around. One of the most persistent myths we encounter at Morrison, Inc. is that homeowners must change their furnace filters every single month, without exception. Today, we’re going to examine this claim and provide you with the facts you need to properly care for your heating system.
The Monthly Filter Change Myth
You’ve probably heard it countless times: “Replace your furnace filter every month or face dire consequences!” While regular filter maintenance is indeed important, the truth is more nuanced than this one-size-fits-all approach suggests.
As your hometown HVAC specialists serving the Mid-Ohio Valley since 1961, we at Morrison, Inc. want to help you understand what’s really best for your system and your wallet.
Factors That Actually Determine Filter Change Frequency
Several variables impact how often you should replace your furnace filter:
- Filter type and quality – Basic 1-inch fiberglass filters may need monthly replacement, but high-quality pleated filters can last 3-6 months
- Household composition – Homes with pets, smokers, or allergy sufferers typically require more frequent changes
- System usage – During peak heating seasons in Marietta, OH or Parkersburg, WV, your system works harder and filters collect more debris
- Home environment – Dustier environments like homes under renovation need more frequent changes
Signs It’s Time for a Filter Change
Rather than blindly following a calendar, look for these indicators:
- Visible dirt accumulation when holding the filter up to light
- Increased energy bills
- Longer heating cycles
- More dust around vents or on surfaces
The Real Consequences of Improper Filter Maintenance
While changing filters too frequently is merely wasteful, not changing them often enough can lead to serious issues:
- Reduced airflow and system efficiency
- Increased wear on system components
- Higher energy consumption and utility bills
- Potential system overheating or failure
- Compromised indoor air quality
Our Professional Recommendation
At Morrison, Inc., we recommend checking your filter monthly but replacing it based on actual conditions rather than a rigid schedule. For most households in Williamstown, Vienna, or Belpre, this typically means:
- 1-2 inch filters: Every 1-3 months
- 4-inch filters: Every 3-6 months
- 5-inch filters: Every 6-12 months
These timeframes should be adjusted based on your specific circumstances as outlined above.
