Your Ultimate Winter Furnace Maintenance Checklist

Category: Furnace

Author: Pat Adams

When winter hits full swing, your furnace becomes the unsung hero of your home. But even heroes need a little care to keep performing their best. With winter in full-swing, it’s the perfect time to show your furnace some love with a little winter furnace maintenance — before any surprise breakdowns leave you bundling up indoors.

5 Things: Winter Furnace Maintenance Checklist

  1. Replace or clean your air filter. A clogged filter restricts airflow, making your furnace work harder than it needs to.
  2. Check your thermostat settings. Make sure it’s accurate and programmed for energy efficiency.
  3. Inspect your vents and registers. Clear away any dust, furniture, or drapes blocking airflow.
  4. Listen for unusual noises. Rattling, banging, or humming could be signs of trouble.
  5. Call your friends at Reliant. Our certified technicians can catch small issues before they turn into big repairs.

Winter maintenance isn’t just about keeping warm — it’s about peace of mind. When your furnace is clean, tuned, and running efficiently, your home stays comfortable and your energy bills stay under control.

And oh yeah – if you’re the type of person who’d rather just skip to Item #5 and save yourself the hassle, have we got a gift for you. We call it the Reliant Comfort Club.
