5 Signs Your Furnace Needs a Tune-Up Before Winter

October 8, 2025

As the fall temperatures drop in Washington, it’s the perfect time to make sure your furnace is ready for the colder months ahead. Regular maintenance not only helps you avoid sudden breakdowns but also keeps your energy bills low and your home comfortable.

Here are five signs your furnace might need a tune-up:


  1. Uneven heating – If some rooms feel colder than others, your system may be struggling to distribute heat evenly.

  2. Strange noises – Rattling, banging, or squealing sounds often indicate loose parts or mechanical issues.

  3. Increased energy bills – A sudden spike in your heating bill usually means your furnace is working harder than it should.

  4. Frequent cycling – If the furnace turns on and off repeatedly, it might need cleaning or adjustment.

  5. Yellow burner flame – The flame should be blue; a yellow or flickering flame may signal incomplete combustion or a carbon monoxide risk.


Scheduling a professional furnace tune-up ensures your system runs safely and efficiently all season long. Contact Mayster Heating & Air to prepare your home for the Washington winter.
