Changing your air filter is one of the most important and easiest maintenance tasks you can do to keep your HVAC system running efficiently. A clean air filter improves indoor air quality, helps your system perform at its best, and can even lower your energy bills. At Tri-City Air, we believe in empowering our customers with the knowledge they need to take care of their HVAC systems. Here’s everything you need to know about changing your air filter.

Why Changing Your Air Filter is Important

Your HVAC system’s air filter traps dust, dirt, pollen, and other airborne particles, preventing them from circulating through your home. Over time, the filter can become clogged with debris, reducing airflow and forcing your system to work harder to maintain a comfortable temperature. This can lead to increased energy consumption, higher utility bills, and even premature wear and tear on your HVAC system.

Key Benefits of Regular Filter Changes:

  • Improved indoor air quality
  • Enhanced system efficiency
  • Lower energy costs
  • Extended lifespan of your HVAC system

How Often Should You Change Your Air Filter?

The frequency of air filter changes depends on several factors, including the type of filter you use, the presence of pets, the number of occupants in your home, and local air quality conditions. As a general rule:

  • Standard Filters: Replace every 1-3 months.
  • High-Efficiency Filters: Replace every 6-12 months, or as recommended by the manufacturer.
  • Homes with Pets or Allergies: Consider changing the filter more frequently, such as every 1-2 months.

Choosing the Right Air Filter

Air filters come in different sizes and efficiency ratings. When selecting a filter, make sure it matches your system’s requirements. The most common rating system is MERV (Minimum Efficiency Reporting Value), which ranges from 1 to 20. Higher MERV ratings indicate better filtration but can also restrict airflow if not compatible with your system.

Types of Filters:

  • Fiberglass Filters: Basic protection, low cost, MERV 1-4.
  • Pleated Filters: Improved filtration, MERV 5-8.
  • High-Efficiency Filters: Superior filtration, suitable for homes with allergies, MERV 9-12.
  • HEPA Filters: Highest filtration level, MERV 13-16, typically used in medical settings.
  • Note: Always consult your HVAC system’s manual or a professional to ensure you choose the right filter.

Steps to Change Your Air Filter

  • Turn Off Your HVAC System: Safety first—always turn off your system before replacing the filter.
  • Locate the Filter Compartment: This is typically found in the return air duct or the blower compartment.
  • Remove the Old Filter: Carefully slide out the old filter. Take note of the direction of the airflow arrows on the filter frame.
  • Insert the New Filter: Ensure the airflow arrows on the new filter match the direction of the system’s airflow. Slide the filter into place.
  • Secure the Compartment: Close any latches or panels securely.
  • Turn On the System: Restore power to your HVAC system and enjoy the benefits of clean air.
  • Tips for Ensuring Maximum Efficiency
  • Set a Reminder: Mark your calendar or set a digital reminder for your next filter change.
  • Inspect Monthly: Even if you plan to change your filter every 3 months, inspect it monthly to ensure it’s not clogged.
  • Keep Extra Filters on Hand: Stock up on filters to avoid delays in changing them.

When to Call the Professionals

While changing an air filter is a simple task, there are times when you may need to call in the professionals:

  • If you notice reduced airflow after changing the filter.
  • If your system cycles on and off frequently, which could indicate a more significant issue.
  • If you’re unsure about the correct filter type or size for your system.
