Why Furnace Filters Matter in Your Rental Property

Furnace filters aren’t just about keeping dust out of the air. They protect your heating and cooling system from damage, improve indoor air quality for tenants, and ensure the system runs efficiently. Neglecting filter changes can cause:
  • Higher utility bills (systems work harder when filters are dirty)
  • Reduced furnace lifespan
  • Poor air quality, leading to tenant complaints
  • Expensive HVAC repairs
Most filters require replacement every 1–3 months, depending on the type, location, and tenant habits. Owners must remember the schedule and confirm that tenants follow through.

Step-by-Step: How to Change a Furnace Filter

If you’re still in the self-managing camp for now, here’s the basic process:
  1. Turn Off the Furnace
    For safety, switch off the furnace at the thermostat and, if needed, at the power source. This prevents the system from running while the filter is out.
  2. Locate the Filter
    Most filters are found in one of two places:
    • Inside the furnace cabinet (behind a service panel)
    • In a return air vent inside the home
  3. Check Filter Size
    The dimensions (e.g., 16 x 25 x 1) are printed on the filter frame. Be sure to match these exactly when buying replacements.
  4. Remove the Old Filter
    Slide the old filter out carefully to avoid spreading dust and debris.
  5. Install the New Filter
    Look for the airflow direction arrow printed on the filter frame. It should point toward the furnace or blower motor. Slide it into place.
  6. Turn the Furnace Back On
    Once the new filter is secure, restore power and reset the thermostat.
  7. Dispose of the Old Filter
    Seal it in a garbage bag to prevent dust from spreading.
While these steps may seem simple, the real challenge for landlords is maintaining a consistent and ongoing schedule. It’s not a “set it and forget it” task—filters must be replaced consistently to avoid bigger issues.

The Real Problem: Time and Tenant Compliance

When you manage your own rental, you either have to:
  • Personally visit the property every few months to change the filter, or
  • Trust your tenants to do it—and hope they actually follow through.
Unfortunately, many tenants forget or don’t prioritize this. By the time you find out, the furnace may already be straining under reduced airflow, leading to costly service calls.
This is one of the many reasons owners turn to property management companies in Portland, Oregon. They don’t just collect rent; they ensure preventative maintenance—like furnace filter changes—happens on time, every time.
