Every fall, the same thing happens across the southwest suburbs: the first cold night arrives, thousands of furnaces turn on for the first time in months, and the ones with a weak igniter, a dirty flame sensor, or a failing inducer motor stop working. That's when repair calls spike and wait times stretch.
A tune-up before the heating season catches most of those problems while the weather is still mild. A technician checks the igniter and flame sensor, tests the blower and inducer motors, inspects the heat exchanger, checks gas pressure, and makes sure the system is venting safely.
Replace your air filter too. A clogged filter restricts airflow, makes the furnace run hotter and longer, and can trip the high-limit switch and shut the system down. In most homes, a standard filter should be changed every one to three months during the heating season.
If your furnace is getting older and the repairs keep adding up, a fall inspection is also a good time to compare repair and replacement costs calmly, before an emergency forces the decision. Our inspections are free, and new unit installations come with $500 off.
