Taunton, MA AC & Heater Filter Maintenance

The air conditioner and heater filter is a simple component that’s vitally important for your system’s operation. Here’s how to keep your HVAC filter in great shape between changes.

  • Check the Filter Monthly: Even if your filter is rated for 3 months, inspect it monthly, especially during peak usage seasons (summer and winter).
  • Replace the Filter Regularly: Most filters should be replaced every 1 to 3 months. Check the manufacturer’s recommendation and follow it based on your household’s needs (pets, allergies, smoking, etc.).
  • Use the Right Filter Size: Always replace the filter with the correct size. A poorly fitted filter allows dust and debris to bypass it and enter your HVAC system.
  • Choose the Right MERV Rating: A filter with a MERV rating of 8–13 is usually ideal for homes. Higher MERVs trap more particles, but can restrict airflow if your system isn’t designed to handle it.

Our expert air handler services can keep your system running efficiently and your home cool. Call us for more information!
