Did you know there’s one small thing that can make a big difference in how long your furnace lasts? Changing your air filter regularly.
It might seem simple (almost too simple), but a dirty or clogged filter is one of the most common reasons we see furnaces struggle—or fail sooner than they should.
Here’s why it matters:
• A dirty filter restricts airflow, forcing your furnace to work harder
• Extra strain means more wear and tear on internal components
• It can lead to higher energy bills and unnecessary breakdowns
• Over time, it can shorten the overall life of your system
In most homes, filters should be checked once a month and replaced about every 3 months, depending on pets, allergies, and system use.
If you’re ever unsure what type of filter you need—or how often yours should be changed—we’re always happy to help. That’s just part of what we do at Kearns Mechanical.
