• Prevent Frozen Pipes: Lake Forest winters can drop to -15 °F, making furnace failures dangerous. Frozen pipes can burst, causing thousands in water damage to your historic home.
• Protect Family Health: Elderly residents and young children are especially vulnerable to cold temperatures. A working furnace is essential for their safety and comfort.
• Avoid Costly Damage: Extended cold exposure can damage hardwood floors, plaster walls, and antique furniture common in Lake Forest's older homes.
• Save Energy & Money: A struggling furnace works harder, consuming 30-50% more fuel. Quick repairs restore efficiency and slash heating bills.
• Maintain Home Value: A functional heating system is crucial for Lake Forest's competitive real-estate market and keeps your family comfortable year-round.

Common Heating Problems We Fix in Lake Forest

• No Heat Output: The furnace runs but produces no warm air. Often caused by a failed igniter, dirty burners, or a cracked heat exchanger.
• Furnace Won't Start: Complete system failure usually indicates a bad thermostat, failed control board, or safety switch activation.
• Insufficient Heat: Weak airflow or low gas pressure results in lukewarm air. Common causes include dirty filters, clogged ducts, or worn blower motors.
• Frequent Cycling: The furnace turns on and off repeatedly, wearing out components and wasting energy. Usually caused by thermostat issues or system oversizing.
• Strange Noises: Squealing belts, rattling ducts, or grinding motors indicate worn parts that need immediate attention.
• High Energy Bills: Inefficient operation due to dirty components, poor airflow, or incorrect settings can spike heating costs significantly.

Our 10-Step Heating Repair Process

1. Safety & System Assessment: Check for gas leaks, test carbon monoxide levels, and verify proper venting before beginning any repairs.
2. Thermostat & Control Testing: Test thermostat accuracy, check wiring connections, and verify control board operation with a multimeter.
3. Ignition System Diagnosis: Test the igniter, flame sensor, and gas valve operation. Replace any components showing signs of wear or failure.
4. Burner Assembly Inspection: Remove and clean burners, check for clogs, and verify proper flame pattern. Adjust air-fuel mixture for optimal combustion.
5. Heat Exchanger Examination: Use a mirror and flashlight to inspect for cracks, holes, or corrosion. A compromised heat exchanger can leak dangerous gases.
6. Blower Motor & Belt Service: Test motor operation, lubricate bearings, and check belt tension. Replace worn belts to prevent system shutdowns.
7. Ductwork & Airflow Check: Inspect for leaks, blockages, and proper insulation. Seal gaps to prevent heat loss and improve efficiency.
8. Gas Line & Pressure Verification: Check gas piping for leaks, test gas valve operation, and verify proper gas pressure at the manifold.
9. Performance Testing: Measure temperature rise, static pressure, and system efficiency. Compare readings to manufacturer specifications.
10. Customer Education & Documentation: Show replaced parts, explain the repair process, and provide maintenance tips. Schedule follow-up visits and answer questions.
