Furnace Maintenance in McHenry, IL

Tune-Ups in Crystal Lake & Surrounding Areas

In and throughout the Chicago area, winters are long and cold—which is why it is crucial to have a heating system that works safely and efficiently. Sometimes known as a tune-up or inspection, maintenance is essential if you want a heating system to have a long healthy life with minimal breakdowns. Scheduling an annual furnace inspection can ensure your furnace is ready for the winter ahead.

If you would like to schedule maintenance for your furnace, contact us online or give us a call!

Why Furnace Maintenance Is Important

Many furnaces break down because of lack of maintenance. Similar to how your car should get an oil change, your furnace should receive an annual tune-up. When you schedule an annual tune-up, you could see:

  • Increased efficiency – As part of our inspection checklist, we will make sure your furnace is working at its peak performance levels to ensure it can reach maximum power efficiently.
  • Lower energy bills – One of the first signs your unit isn’t working properly is a spike in monthly energy bills. Annual maintenance ensures your unit is clean and not working harder than it needs to.
  • Longer lifespan – When you schedule annual maintenance, you can expect your unit to last longer with fewer major breakdowns.
  • Fewer breakdowns – Many common breakdowns can be avoided if the unit was properly taken care of. Avoid costly breakdowns and schedule annual maintenance.

Furnace Maintenance Checklist

During a tune-up,, our technicians will complete an extensive list of tasks that will help prolong the life of your unit, including:

  • Test and adjust the burners for maximum efficiency
  • Inspect the heat exchanger for hairline cracks
  • Inspect and adjust the ignition system
  • Calibrate the blower assembly
  • Inspect and test the vent pipe assembly
  • Test and reset the thermostat
  • Adjust and measure gas pressure to the unit
  • Replace disposable filters
  • Lubricate moving parts
  • Tighten electrical connections where necessary
  • Test for continuity and amp draw across the blower motor
