Heating & Cooling in Illinois

From lake-effect cold to humid continental summers, Algonquin systems face some of the widest temperature ranges in the country — furnaces that handle subzero Januaries and air conditioners that carry 95-degree Julys. Freeze-thaw cycles are hard on outdoor units and refrigerant lines.

Seasonal Tips for Illinois Homes

• Replace the furnace filter before heating season starts — restricted airflow is the top cause of winter no-heat calls.
• Test the furnace on the first cool fall day, not the first freezing night, so any repair happens before the rush.
• Keep snow and ice cleared from heat pump outdoor units and exhaust vents to prevent shutdowns and carbon monoxide risks.
• Install a carbon monoxide detector on every floor if you heat with gas or oil, and check batteries each fall.
