Common HVAC Misconceptions
One of the most widespread myths in home comfort management is the belief that you must replace your HVAC air filter every single month, no exceptions. At Cheshire Heating & Air, we frequently encounter homeowners who’ve been unnecessarily spending money on monthly filter replacements, regardless of their actual usage patterns.
The Reality of Filter Replacement
The truth is, the frequency of air filter replacement depends on several factors:
• Household size
• Number of pets
• Local air quality
• System usage
• Filter quality and type
When Should You Actually Replace Your Filter?
For the average household:
• Basic 1-inch filters: Every 2-3 months
• High-end pleated filters: Every 4-6 months
• Homes with pets or allergies: More frequent changes may be needed
The best practice is to inspect your filter monthly and look for these signs:
• Visible dirt accumulation
• Reduced airflow
• Increased energy bills
• More dust around your home
The Cost Impact
Blindly following the monthly replacement rule could cost you up to $180 annually in unnecessary filter purchases. Instead, understanding your specific needs and monitoring filter condition can help you maintain optimal system performance while saving money.
Remember, while regular maintenance is crucial for your HVAC system’s efficiency, not every maintenance task needs to follow a rigid monthly schedule. When in doubt, let your system’s performance and your home’s specific conditions guide your maintenance decisions.
