When cold weather hits, you want peace of mind knowing your furnace is ready to keep your home safe and warm. A professional furnace tune-up from Siemer Heating, Cooling & Plumbing ensures your system runs efficiently, prevents breakdowns, and extends the life of your equipment. As a family-owned business serving Northwest Indiana and the south suburbs of Chicago since 1987, we take pride in treating every customer like family.

Whether you have a gas furnace or another type of heating system, our licensed technicians will deliver a heating tune-up that’s thorough, affordable, and designed to give you comfort all season long.

What Is a Furnace Tune-Up?

A furnace tune-up service is a comprehensive inspection, cleaning, and adjustment of your heating system. Think of it as preventative care for your furnace. Instead of waiting for a breakdown, our team checks every part of your unit, cleans key components, and makes sure your system is operating safely and efficiently.

By scheduling a yearly tune-up, you’ll enjoy several advantages that go beyond simple heating performance, including:

  • Lower energy bills thanks to improved efficiency
  • Fewer emergency repairs when issues are caught early
  • Better indoor air quality from cleaner system components
  • Longer system lifespan with reduced wear and tear
  • Peace of mind knowing your family is safe

As a family-owned company, we treat every tune-up like it’s for our own home, ensuring your furnace is safe, efficient, and ready to keep your family comfortable all winter long.

What’s Included in a Heating Tune-Up?

Many homeowners are surprised by how many steps go into a proper gas furnace tune-up. At Siemer, we follow a detailed checklist that covers both safety and performance. This ensures every component of your heating system is inspected and adjusted as needed. Our tune-ups typically include:

  • Inspecting and cleaning burners, heat exchangers, and the ignition system
  • Checking electrical connections and tightening where needed
  • Testing the thermostat for accuracy and recalibration
  • Replacing or cleaning air filters
  • Lubricating moving parts for smooth operation
  • Checking carbon monoxide levels and safety controls
  • Inspecting the venting and flue system

Because our technicians cover every angle, you won’t be left wondering if something was missed. The result is a furnace that’s ready to run reliably through the harshest Midwest winters.

When to Schedule a Furnace Tune-Up

Timing is one of the most important factors in furnace maintenance. We recommend scheduling tune-ups once per year, ideally in early fall before heavy use begins. That way, we can catch small issues before they turn into costly repairs, and you’ll enter winter with confidence.

If your furnace hasn’t been serviced in over a year, now is the best time to book your appointment. Don’t wait until your system breaks down on a freezing night. Be proactive instead of reactive.

DIY vs. Professional Heating Tune-Up

Homeowners sometimes ask if they can handle a tune-up themselves. While it’s smart to replace filters regularly and keep your furnace area free of dust and clutter, a true furnace tune-up requires specialized tools and training.

Here’s a simple way to think about it:

  • Homeowners can safely handle routine filter changes and basic upkeep.
  • Professionals are needed for combustion checks, electrical testing, carbon monoxide monitoring, and in-depth cleaning.

By trusting Siemer’s licensed team, you’ll know that every aspect of your furnace is getting the attention it deserves.
