A heating system may break down with little to no warning at all. It will go from seemingly operating “just fine” throughout the day and night to suddenly halting, or just not turning on at all. This is uncommon, particularly if you had fall maintenance. Even with that tune-up though, unless there’s a sudden electrical failure, a furnace or heating system usually gives off some sign it’s about to fail.
Often, this sign is a loud and/or unfamiliar noise. It may be accompanied by some unusual performance from your heating system, but this isn’t always the case. We don’t encourage you to try to repair the system on your own, but at least you can be prepared with what might be going on, before you call a pro for expert heater repair in Alameda, CA.
