Furnace Repair In Milwaukee

Stay Warm All Season Long with Furnace Repairs & Tune-Ups from Blau Sudden Service

Nothing reminds us more of the winter cold than a furnace that either isn’t working well, or stops working all together.

As things get worse, you start using double and triple blankets at bedtime, extra layers of clothing during the day…you right even buy one or more electric space heaters or too to augment what little heat your furnace is providing.

Our advice is:  “Don’t wait that long!”  Because if your furnace isn’t doing its job, it needs fast and expert attention…the kind you can depend on from Blau Sudden Service.

Warning Signs Your Furnace Needs to Be Serviced

Your furnace plays a crucial role in keeping your home warm and comfortable during cold weather. Regular maintenance is essential to ensure it operates efficiently and safely. Here are some warning signs that indicate your furnace may need servicing:

  • Strange Noises: Rattling, banging, or squealing sounds could indicate loose parts or motor issues.
  • Higher Energy Bills: Sudden spikes without increased usage might signal efficiency problems.
  • Uneven Heating: Certain rooms being colder could point to duct or thermostat issues.
  • Frequent Cycling: On-off cycling could mean clogged filters or airflow problems.
  • Yellow Pilot Light: A yellow flame could indicate carbon monoxide presence; it's dangerous.
  • Foul Odors: Burning or musty smells could indicate dirty filters or mold growth.
  • Poor Air Quality: More dust or particles indoors could stem from a faulty furnace.
  • Soot or Rust: Visible soot or rust around the furnace may indicate combustion problems.

If you notice any of these signs, it's best to have a professional inspect your furnace promptly to ensure safety and efficiency. Regular maintenance can prevent costly repairs down the line.
