Cold Illinois winters put a heavy strain on heating systems, and when temperatures drop, the last thing you want is a malfunctioning furnace. Understanding common winter heating problems can help you spot issues early and prevent a complete system breakdown. Here are some frequent heating problems and how to handle them.
Uneven Heating Throughout the Home
If some rooms in your home are warmer than others, it could be due to clogged air filters, blocked vents, or an unbalanced duct system. Start by checking and replacing the air filter if it’s dirty. Make sure vents are open and unobstructed. If the problem persists, you may need a professional to assess your ductwork to seal leaks or fix an improper design.
Furnace Blowing Cold Air
A furnace that runs but doesn’t produce warm air can be frustrating. The issue may stem from a faulty thermostat, a dirty flame sensor, or an extinguished pilot light. Check that your thermostat is set correctly and has fresh batteries. If the pilot light won’t stay lit or the burner won’t ignite, a technician should inspect the system for deeper issues like a malfunctioning ignition or gas valve problem.
Frequent Cycling On and Off
Short cycling, where your furnace turns on and off too quickly, can indicate airflow restrictions, thermostat malfunctions, or an oversized furnace. A clogged air filter is a common culprit, so replacing it is a good first step. If the problem continues, a professional can diagnose whether there’s an issue with the heat exchanger, blower motor, or thermostat calibration.
Unusual Noises from the Furnace
Rattling, banging, or squealing sounds from your furnace should never be ignored. Rattling may indicate loose components, while banging could be a delayed ignition issue. Squealing often signals a worn-out blower belt. Scheduling an inspection can help prevent minor issues from turning into major repairs.
Rising Energy Bills
If you notice a sudden spike in your heating costs, your system may be working harder than necessary due to dirty filters, poor insulation, or aging components. Regular furnace maintenance, including cleaning and tune-ups, can improve efficiency and help lower energy consumption.
