Common HVAC Myths Debunked: Filter Changing Frequency
Since 1949, Perry Heating, Cooling, and Plumbing has been the leading HVAC and plumbing company for Tucson, AZ and surrounding communities. Over these decades, we’ve heard countless myths about HVAC maintenance, but one persistent misconception keeps costing homeowners money across Catalina Foothills, Oro Valley, and Casas Adobes.
The Myth: Change Your Air Filter Every 30 Days
Many Tucson homeowners religiously change their HVAC filters monthly, believing this one-size-fits-all approach is best. However, this oversimplified rule isn’t always necessary and could be wasting your money.
The Truth: Filter Changes Depend on Multiple Factors
The actual frequency for changing your air filter depends on:
• Household size
• Number of pets
• Local air quality
• Filter quality rating
• Season and HVAC usage
• Presence of allergies or respiratory conditions
Real Guidelines for Arizona Homes
For most households in the Tucson area:
• Basic 1-inch filters: Every 60-90 days
• High-end pleated filters: Every 4-6 months
• Homes with pets: Every 45-60 days
• Homes with allergies: Every 30-45 days
Remember, visual inspection is your best guide. If your filter looks dirty before these intervals, change it early. Trust your eyes over the calendar.
