Common Furnace Problems We See (and Fix)
Most furnace issues start out small—and if you catch them early, you can avoid a total system failure. Our team sees the same core problems across dozens of homes every week. We’ll pinpoint the source of the issue, explain what’s happening in plain language, and fix it using parts and methods we stand behind.
Here are a few of the most common furnace issues and what they typically mean:
- Cold air from vents – This could point to a faulty ignition system, a dirty flame sensor, or a problem with the thermostat.
- Frequent on/off cycling – Often caused by clogged filters, poor airflow, or a malfunctioning heat exchanger.
- Unusual smells or burning odors – Could indicate dust buildup, electrical issues, or overheating components.
- Loud banging or rattling sounds – Loose parts, cracked heat exchangers, or worn blower bearings are often the culprit.
- Pilot light won't stay lit – Could be a thermocouple issue or a blocked intake/exhaust.
You don’t need to know exactly what’s wrong—that’s our job. But if something feels off, don’t wait it out. Let us take a look before it turns into a bigger (and more expensive) problem.
