HVAC Repair Dekalb IL | Call All-Star Heating & Air Conditioning

Furnace ignition failure is a frequent winter issue in Dekalb, often due to a dirty flame sensor, a faulty hot surface ignitor, or issues with the gas valve. These components can wear out or get coated with debris over time. Our technicians are experts in diagnosing and safely repairing these ignition problems to restore heat to your home quickly and reliably.

Absolutely. Inconsistent temperatures can often be traced back to a thermostat malfunction or restricted airflow. While we'll check your thermostat's calibration and location, a thorough air duct cleaning removes built-up dust, pet dander, and debris that can block vents and strain your HVAC system. This allows for balanced airflow and more consistent heating and cooling throughout your Dekalb home, improving both comfort and efficiency.

Our preventative maintenance service is designed specifically to address the common causes of winter breakdowns. We perform a comprehensive check, including cleaning the flame sensor and ignitor to prevent ignition failure, testing thermostat accuracy, inspecting heat exchangers for cracks, and ensuring all electrical connections are secure. This proactive approach identifies small issues before they leave you without heat during a Dekalb cold snap, saving you money on emergency repairs and improving system longevity.
