Posted on by HVAC Canton

Separating Fact from Fiction in HVAC Maintenance

At C. Albert Matthews, we believe in providing our customers with accurate information to help them maintain their heating and cooling systems efficiently. One common myth we often encounter is the belief that HVAC air filters need to be replaced every month, regardless of circumstances. Let’s dive into why this isn’t always necessary and what factors actually determine when you should change your air filter.

The Monthly Replacement Myth

Many homeowners in Cambridge, Easton, and surrounding Maryland areas have been led to believe that replacing their HVAC air filter every 30 days is a hard and fast rule. However, this one-size-fits-all approach isn’t always the most effective or economical.

Factors Affecting Air Filter Lifespan

The truth is, the frequency of air filter replacement depends on several factors:

  • Home size
  • Number of occupants
  • Presence of pets
  • Air quality in your area
  • Type of filter used

When to Actually Replace Your Air Filter

Instead of adhering to a strict monthly schedule, consider these guidelines:

1. For basic 1-inch fiberglass filters: Every 30-60 days
2. For higher-end pleated filters: Every 3-6 months
3. For homes with pets or allergies: Every 20-45 days

The Importance of Regular Checks

Rather than blindly replacing your filter monthly, we recommend checking it regularly. If it appears dirty or clogged, it’s time for a replacement. This approach ensures you’re not wasting money on unnecessary replacements while still maintaining optimal system performance.

Conclusion

By understanding the factors that influence air filter lifespan, you can make informed decisions about when to replace yours. This not only saves you money but also helps maintain your HVAC system’s efficiency. If you’re unsure about your air filter needs or have any questions about heating, cooling, plumbing, or electrical services in Algonquin, Trappe, Centreville, or Denton, MD, don’t hesitate to contact C.
