Furnace Maintenance Checklist Before Chicago Winters Hit With Chicago winters often bringing sudden cold snaps and long stretches of freezing weather, furnace problems that seem “small” in fall can become big emergencies in mid-January. A short maintenance routine now can reduce the risk of unexpected shutdowns, help your system run efficiently, and support more consistent heating for your home. 1) Confirm the basics: power, thermostat, and airflow Start with the components you can quickly verify. Check that the furnace has proper power and that the thermostat is set correctly for heating mode.

Municipal water typically receives multiple treatment steps, such as disinfection (often chlorine or chloramine), sediment control, and sometimes additional processes depending on source water quality. In many regions, this lowers the likelihood of certain contaminants compared with untreated groundwater, though distribution conditions and local variations can still affect quality. What well water may contain Because well water is not treated through a municipal plant, it may carry natural or human-influenced substances. C ... Read more »
