5 common furnace problems in extreme cold
Here are some common furnace problems that occur in extreme cold.
- Furnace pilot light problems: In extremely cold temperatures, the pilot light in your furnace can go out as a result of condensation or air drafts. If this happens, you will likely need to relight the pilot light.
- Ignition problems: The ignition system on some older furnaces may fail when it gets too cold outside. This can cause your furnace to fail to turn on or make loud banging noises when it is trying to start up.
- Frozen heat exchanger: If the heat exchanger in your furnace freezes, it can cause a buildup of condensation and ice inside the unit, leading to inefficiency and possible damage to other components.
- Blocked air filter: In extremely cold weather, the air filter in your furnace may become clogged with snow or ice, leading to restricted airflow and reduced efficiency.
- Faulty thermostat: If your thermostat is not working properly in cold weather, it can cause problems with your furnace’s temperature regulation and result in uneven heating throughout your home.
It is important to keep an eye out for any of these potential furnace problems in extreme cold weather and address them as soon as possible. Doing so can help you avoid costly repairs and ensure the safety and efficiency of your heater during the colder months.
