Why Furnace Prep Matters
An idle furnace can develop issues—dust buildup, ignition problems, or inefficiencies—that may cause breakdowns or safety hazards during the coldest nights.
Step 1: Replace or Clean Your Filter
In Elmhurst and Naperville, changing your filter every 1–3 months helps maintain airflow and system health.

Step 3: Test Your Thermostat Settings
Switch to “heat” and verify that your system responds properly avoiding a cold surprise on your first chilly night in Wheaton or Downers Grove.
Step 4: Inspect Vents and Ductwork
Ensure vents are clear of obstructions and listen for unusual duct noises—common culprits of uneven heating in Glen Ellyn.
Step 5: Check Carbon Monoxide & Smoke Detectors
Safety first:
- Replace batteries and test units.
- Upgrade to a digital carbon monoxide meter for more accurate readings.
Step 6: Be Aware of Older Furnace Risks
If your furnace is over 20 years old, even if you’re not detecting CO now, it can still pose serious risk. Warped heat exchangers or worn parts may compromise safety—get a professional inspection.
Step 7: Improve Comfort with a Smart Thermostat
