A home furnace is an essential appliance that helps keep your home warm and comfortable during the cold months. A properly functioning furnace keeps the environment cozy and helps reduce energy costs. However, the furnace can break down suddenly, which can be frustrating, especially when temperatures drop. Thus, it's vital to know the common furnace problems and how to fix them or consider calling a professional.
Lack of Maintenance
One of the most common causes of furnace failure is a lack of maintenance. Regular maintenance helps prevent unexpected problems and extends the lifespan of your furnace. Ensure that you have a licensed technician inspect and tune up your furnace at least once a year. The technician will check for leaks, clean the furnace, and make sure the system is running efficiently.
Dirty or Clogged Filters
Another issue that can cause your furnace to malfunction is dirty or clogged filters. If the filter is dirty, airflow decreases, forcing the furnace to work harder than necessary. This can result in higher energy bills and damage to the furnace. To prevent this, replace filters every few months, especially during months of heavy usage.
The thermostat is a vital part of the furnace and controls the temperature in your home. If the thermostat fails, your furnace will produce heat inconsistently or stop heating. Ensure the thermostat is functioning properly by testing it or replacing its batteries.
Pilot or Ignition Control Issues
Older furnaces have pilot lights that may go out, causing your furnace to stop working. Newer furnace models have an electronic ignition control system that can develop issues. If your furnace doesn't light, consult your manufacturer's instructions on how to relight the pilot or ignition control system. If you are unfamiliar with the process, it's best to reach out to a professional to fix it.
Wear and Tear
Over time, your furnace experiences wear and tear, which can lead to a breakdown. Worn-out belts, bearings, and other parts can cause strange noises, reduced heating capacity, or critical failure. Regular maintenance can help reduce the risk of wear and tear. When you hear strange noises or notice reduced heating capacity, call a professional for a furnace inspection.
Faint burning smells, cold air, or loud banging noises are red flags indicating a need for furnace repair or maintenance. If you are experiencing any furnace problems, it's best to consult a professional to ensure your safety and the longevity of your furnace. Don't let a malfunctioning furnace ruin your winter comfort.
