Problem: Your furnace may turn off prematurely if the thermostat is malfunctioning or set incorrectly. This could happen if it’s placed near a heat source or sunlight, causing it to shut off the furnace too early.
Home Solution: Check the thermostat settings and make sure it’s not set to “auto” but rather to “heat.” If possible, relocate the thermostat away from heat sources.
Tools Needed: Screwdriver (to adjust or relocate the thermostat), replacement batteries if needed.
Why Call a Professional: A faulty thermostat might not seem like a big issue, but improper calibration can lead to inefficient heating, high energy bills, or frequent cycling on and off. A professional from Angels Heating Company can correctly assess the placement and functionality of your thermostat to avoid bigger issues down the road.
Problem: Clogged air filters can restrict airflow, causing the furnace to overheat and shut off as a safety precaution.
Home Solution: Replace the air filter regularly, ideally every 1-3 months during the heating season.
Tools Needed: Replacement air filter, possibly a vacuum to clean out dust around the filter compartment.
Why Call a Professional: While replacing an air filter is simple, persistent overheating due to airflow issues can damage the furnace. Regular maintenance by professionals ensures that your system runs efficiently and catches any potential airflow problems early on.
Problem: The flame sensor ensures the burner ignites. If it’s dirty or malfunctioning, the furnace may shut off for safety reasons.
Home Solution: Carefully clean the flame sensor using a soft cloth or light sandpaper, taking care not to damage it.
Tools Needed: A screwdriver is needed to access the sensor, and a soft cloth or sandpaper is required for cleaning.
Why Call a Professional: Cleaning the flame sensor is a delicate task. If not done correctly, it could lead to a faulty sensor, making your furnace unsafe. A technician from Angels Heating Company can thoroughly clean or replace the sensor, ensuring safe and consistent operation.
Problem: If air vents are blocked by furniture or closed, the furnace could overheat and shut off as a safety measure.
Home Solution: Make sure all vents are open and unblocked to allow proper airflow throughout the home.
Tools Needed: None—just check your furniture placement and vent settings.
Why Call a Professional: Frequent overheating might indicate deeper airflow problems, such as ductwork blockages or an improperly sized system. Our professionals can inspect your system and ductwork to ensure it’s operating efficiently and safely.
Problem: Short cycling happens when the furnace turns on and off rapidly without heating your home correctly. This is often caused by an oversized furnace or issues with the thermostat.
Home Solution: Adjust the thermostat settings and monitor whether the furnace runs for more extended periods.
Tools Needed: The thermostat user manual for guidance and a timer to track the furnace cycles.
Why Call a Professional: Short cycling leads to unnecessary wear and tear on your furnace. If this continues, it could shorten the lifespan of your system. A professional from Angels Heating Company can evaluate the furnace size and ensure everything is working as it should.
Problem: Ductwork that is clogged or leaking can reduce airflow, causing the furnace to overheat and shut off.
Home Solution: Inspect visible ductwork for leaks or blockages and seal any small gaps with foil tape.
Tools Needed: Flashlight, foil tape for minor repairs.
Why Call a Professional: Ductwork issues are often difficult to detect and repair appropriately without the right equipment. Professionals can conduct a comprehensive duct inspection and repair leaks to improve airflow and system efficiency.
Problem: The limit switch controls the fan, and if it’s malfunctioning, it could cause the furnace to shut off.
Home Solution: This is a more technical issue and typically requires professional help to avoid further damage to the furnace.
Tools Needed: Multimeter (to check electrical components), but professional tools are usually necessary.
Why Call a Professional: A malfunctioning limit switch can cause overheating, increasing the risk of severe damage to your furnace. Angels Heating Company can safely diagnose and repair the issue, ensuring your system runs smoothly.
