The Truth About HVAC Air Filter Changes: Stop Wasting Your Money
Common HVAC Myths That Cost You Money
One of the most persistent myths in home comfort is that you need to change your HVAC system’s air filter every single month, no exceptions. At Guardian Heating & Cooling, we’re here to set the record straight about this costly misconception that’s affecting many Chicago-area homeowners.
The truth is, the frequency of air filter changes depends on several factors:
- Number of occupants in your home
- Presence of pets
- Local air quality
- Type of filter being used
- Season and HVAC usage
For example, a single person living in a Northbrook apartment with no pets might only need to change their filter every 3-4 months. Meanwhile, a family of five in Lincoln Park with two dogs and a cat might need monthly changes during peak seasons.
How to Know When It’s Really Time to Change
Instead of blindly following a calendar-based schedule, we recommend checking your filter’s condition every 30 days. Hold it up to a light source – if you can’t see light passing through, it’s time for a replacement. This simple test can save you hundreds of dollars annually on unnecessary filter changes while ensuring your system operates efficiently.
Remember, an overly dirty filter can increase your energy bills and strain your system, while changing it too frequently is simply throwing money away. Finding the right balance for your specific situation is key to maintaining both your HVAC system and your budget.
