The Truth About Furnace Filter Changes: More Often Isnt Always Better
As a trusted HVAC service provider in Colorado, Allied Heating & Air Colorado frequently encounters homeowners who believe that changing their furnace filters monthly is always the best practice. Let’s explore why this common misconception might actually be costing you money without providing additional benefits.
Understanding Filter Replacement Timing
The ideal frequency for changing your furnace filter depends on several factors:
- Home occupancy levels
- Number of pets
- Local air quality
- Filter quality and thickness
The Reality of Filter Lifespans
High-quality 4-inch pleated filters can effectively last up to 6 months, while basic 1-inch filters might need replacement every 2-3 months. Blindly following a monthly replacement schedule could mean throwing away perfectly good filters.
Cost Implications
Unnecessary filter changes not only waste money but can also:
- Create unnecessary environmental waste
- Risk improper installation through frequent handling
- Lead to unnecessary maintenance checks
The Better Approach
Instead of adhering to a strict monthly schedule, we recommend:
1. Visually inspecting your filter every 30 days
2. Replacing when visibly dirty or according to manufacturer specifications
3. Considering upgraded filters for longer life spans
Remember, proper furnace maintenance isn’t about following arbitrary schedules but about responding to your specific home’s needs.
