Why Heating Tune-Ups Matter

Here are a few of the biggest reasons homeowners in Chicago make a habit of scheduling regular heating tune-ups:

  • Safety & peace of mind:

We inspect for gas leaks, carbon monoxide, ignition system issues, and heat exchanger integrity.

  • Energy efficiency and cost savings:

A well-tuned system uses less fuel, lowering monthly heating costs.

  • Fewer breakdowns:

Minor issues are caught early before they become major repairs.

  • Extended equipment life:

Routine service helps your furnace or heater last longer.

  • Warranty compliance:

Many manufacturers require maintenance to maintain coverage.

  • Cleaner indoor air:

Cleaning filters and blower assemblies improves airflow and air quality.

Together, these benefits protect both your home and your budget — especially during Chicago’s harsh winter season.

What’s Included in Deljo’s Heating Tune-Ups?

Every heating system is unique, which is why our technicians tailor each tune-up to your specific equipment. However, every service includes a detailed inspection, cleaning, and calibration process designed to restore peak performance.

During your appointment, a certified HVAC technician will:

  1. Verify system safety by inspecting gas lines, combustion areas, ignition components, and venting.
  2. Conduct combustion analysis and calibration to measure oxygen levels, gas pressure, and burner efficiency.
  3. Clean and lubricate moving parts, including burners, fans, and blower motors, to reduce friction and wear.
  4. Test electrical and control systems by checking wiring, relays, capacitors, and switches.
  5. Assess airflow and duct performance to identify leaks or blockages and ensure proper distribution.
  6. Calibrate the thermostat for accurate temperature control and efficient cycling.
  7. Run a full performance test to measure temperature rise, pressure levels, and overall operation.
  8. Provide a written report with repair recommendations and efficiency tips tailored to your system.

After your tune-up, our team will walk you through the results so you know exactly how your heating system is performing and what (if anything) needs attention.

When to Schedule a Heater Tune-Up

Timing is key to getting the most from your service. The best time for a tune-up is before winter begins, so your system is fully prepared when temperatures drop. However, there are other times it’s smart to schedule maintenance as well.

You should book a heater tune-up if:

  • It’s been over a year since your last service.
  • You’ve noticed uneven heating, strange noises, or higher energy bills.
  • You recently had a major repair or installation.
  • You’re a member of our HVAC Maintenance Program, and it’s time for your seasonal visit.

By planning ahead, you’ll avoid peak-season scheduling delays and ensure your home stays warm when it matters most.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
