📆 How Often to Change Your Furnace Filter
The frequency of changing your furnace filter depends on several factors, including the type of filter and your home’s specific needs. However, general guidelines can help you determine the optimal schedule.
Monthly Checks
Inspect your filter every month, especially during peak usage seasons like winter and summer. Regular monthly inspections help ensure that the filter is functioning correctly and efficiently. This habit allows you to catch any potential issues early on, such as clogs or damage, which can otherwise lead to poor air quality and higher energy costs. Maintaining this routine helps in keeping your HVAC system running smoothly and ensures that the indoor air remains clean and healthy for you and your family.
Standard Replacement Intervals
- Fiberglass Filters: These filters should be replaced every 30 days. They are the most basic type of filter and are inexpensive, but they need frequent changing to maintain effectiveness.
