Winter is the most stressful time of year for furnaces. The longer you use your furnace every day, the more strain you’re going to put on the system. That makes it more likely for problems to occur. If you want to keep your furnace in the best possible condition, you should keep an eye out for the following issues.
One of the easiest ways to identify issues with your furnace is to listen for strange noises coming from the system. Which noise your furnace is making depends on the type of problem it has. For example, a deep booming noise on startup very likely means that your burner assembly is clogged. A grinding sound often indicates that your air handler motor is overheating. If you notice any sort of weird sound coming from the furnace, call for repairs to make sure that the system is functioning properly.
Short cycling is when your furnace turns itself on and off every few minutes. This is caused by heat becoming trapped in the furnace, causing it to overheat and shut itself down as a safety measure. Once the furnace has cooled, it restarts and overheats again until the problem is fixed. This dramatically increases the wear and tear on the system, making problems more frequent and shortening the lifespan of the furnace.
Even if there are no obvious symptoms that indicate a problem, there are still ways to tell that your furnace needs repair. One of the best ways to do that is to monitor your heating bills. If your bills suddenly start to rise without any obvious reason, it might mean your furnace needs repair.
