Get Your AC Ready Before Southern Illinois Summer Heat

Humid summers in Southern Illinois and communities within about 30 miles of Steeleville put real load on air conditioners and heat pumps in cooling mode. A little preparation in spring can prevent emergency calls on the hottest days.

Keep the outdoor unit breathing

Clear leaves, grass clippings, and debris from around the condenser. Gently straighten bent fins if you see damage, and maintain a few feet of clearance for airflow. Avoid stacking mulch or storing items against the cabinet.

Don’t skip professional maintenance

A licensed technician measures refrigerant charge, checks electrical connections, cleans coils as needed, and verifies safe drainage. Low refrigerant or weak capacitors often fail under peak load—catching them early is cheaper than a compressor replacement.

Help your system indoors too

Replace the air filter, verify the thermostat schedule, and consider shading south- and west-facing windows during peak sun. Small changes reduce runtime and extend equipment life.
