When you schedule a heating system service, a technician typically inspects the burner, heat exchanger, and controls, cleans key components like the filter and blower, checks gas pressure and safety devices, and tests overall efficiency. They look for wear, leaks, or blockages that could cause breakdowns or carbon monoxide risks. The goal is to keep your system running safely and reliably, not to fix major parts—that’s usually extra. It’s a thorough checkup, not a repair.
