1) IMPROPER MAINTENANCE
Regular maintenance by a registered service professional is required to keep your system in good working order. Many of the most common furnace repairs can be prevented by having your furnace serviced by a professional service contractor on a regular basis. You’ve probably spent thousands of dollars on your home heating system. Why not safeguard that investment? If you fail to do regular maintenance, you will most likely face unexpectedly expensive breakdowns, increased energy costs, poor performance, and irritation.
2) UNCLEAN FILTERS
One of the most important things you can do to extend the life and effectiveness of your furnace is to replace your filter on a regular basis. If your filter is clogged, airflow will be restricted, requiring your unit to work significantly harder to circulate air around your home. This puts an unneeded pressure on your furnace’s blower and causes comfort difficulties. A clogged filter can also cause the furnace to overheat and shut down on the high setting.
3) PROBLEMS WITH THE PILOT OR THE IGNITION
Ignition issues can be caused by a variety of factors. A filthy pilot, flame sensor, or burners might result in a pilot outage, short cycling, furnace lockout, or delayed burner ignition. It could also be due to a gas supply issue or just wear and tear on an ignition component that has to be replaced, such as the hot surface ignitor or thermocouple. In any case, because this involves dangerous elements such as natural gas and high voltage, it is advisable to have these problems handled by a skilled service specialist.
4) THERMOSTAT FAILURES
There are numerous thermostats available, both programmable and non-programmable. When a homeowner believes their furnace is not working properly, it is frequently due to a problem with the thermostat or how it is set. Referring to your owner’s manual and going over the operating instructions may save you money on a costly or unneeded service call. Batteries in programmable thermostats may need to be replaced on a regular basis. If the problem persists, a service expert can promptly diagnose it.
5) MACHINE WEAR AND TEAR
Your heating system is supported by a variety of mechanical components. The usual wear and tear of these components can have a negative impact on the functioning of your machine. Belts and bearings, for example, can cause overheating, inadequate heating, and ventilation problems. Regular maintenance should include checking for worn or strained belts and, if necessary, oiling bearings and motors.
