Heating System Maintenance

Reliable warmth through Illinois winters depends on a well-maintained heating system. Our Heating System Maintenance service provides a thorough 21-point inspection for furnaces, boilers, and heat pumps—catching minor issues before they escalate into costly repairs.

Heating Maintenance

Illinois winters can stretch from October through April, with temperatures often below freezing. A properly maintained heating system not only keeps you comfortable but also prevents dangerous carbon monoxide leaks and reduces utility bills. Our Heating System Maintenance service provides a comprehensive 21-point inspection for furnaces, boilers, and heat pumps—ensuring your system runs safely and efficiently all season long.

What’s Included in Our 21-Point Inspection

During your maintenance visit, our technician will:

• Clean and inspect burner assembly (gas/oil furnaces) or burner nozzles (oil boilers)
• Check heat exchanger for cracks or corrosion (carbon monoxide risk)
• Test safety controls (limit switches, pressure switches, flame sensors)
• Lubricate blower motor and inspect belt tension (if applicable)
• Verify proper refrigerant charge and defrost cycles on heat pumps
• Measure electrical current draw on motors and test capacitors
• Inspect and replace air filter (standard pleated filters provided)
• Blow out condensate/drain lines to prevent water damage and mold growth
• Inspect ductwork for leaks, mold, and proper insulation
• Calibrate thermostat and test system cycles for safe operation

Signs You Need Preventive Maintenance

Schedule maintenance if you notice any of these signs:

• A drop in heating capacity or inconsistent room temperatures
• Unusually high energy bills without a change in thermostat settings
• Loud or unusual noises (banging, rattling, or whistling)
• Burning or musty smells when the system runs
• Frequent cycling on and off or failure to maintain setpoint
