Common Reasons For A Furnace Not Working After Snow Storm
After a snowstorm, several issues might cause your furnace to stop working. Understanding these reasons can help you troubleshoot quickly.
Power Supply Issues
Power supply issues often lead to furnace failures. You might experience a tripped circuit breaker due to electrical surges during a storm. Checking your breaker box is a good first step. If the breaker has tripped, resetting it might restore power. Additionally, ensure that the furnace power switch is turned on.
Blocked Venting
Blocked venting can prevent your furnace from functioning properly. Heavy snow might pile up against the exhaust vents, restricting airflow. Inspect the outside vent for any snow or debris. Clearing the area can allow for proper ventilation, ensuring your furnace operates efficiently. If your furnace has a flue pipe, make sure it’s clear, as blockages can pose safety risks and affect performance.
Safety Precautions To Take
Before attempting any troubleshooting, prioritize your safety. Follow these precautions to ensure a secure environment when dealing with your furnace after a snowstorm.
Turn Off The Furnace
Turn off the furnace immediately to stop any potentially dangerous situation. Locate the power switch or the circuit breaker controlling the furnace, and switch it off. Allow the furnace to cool down before inspecting it further. This step prevents any risk of electric shock or fire.
Check The Thermostat
Check the thermostat settings after turning off the furnace. Ensure it’s set to “heat” and the desired temperature is higher than the current room temperature. If the thermostat’s display is blank, replace the batteries if it’s battery-operated. If it’s hardwired, check the circuit breakers for any tripped switches. Digging into the settings helps confirm the system should be operational, simplifying your troubleshooting process.
Troubleshooting Steps
You can quickly address furnace issues after a snowstorm by following these troubleshooting steps.
Inspect The Air Filter
Inspect the air filter to ensure it’s not clogged. A dirty filter restricts airflow, causing the furnace to overheat and shut down. Check it every month during the heating season. If it looks dusty or dirty, replace it with a new one. Use filters rated for your furnace type for optimal performance.
Clear Any Snow Around The Furnace
Clear any snow accumulation around the furnace’s exterior. Snow can block the exhaust vent, leading to insufficient airflow. Use a shovel or broom to gently remove snow and ice from the area. Ensure that the vent is free from debris, such as leaves or branches, to promote proper ventilation and safe operation.
When To Call A Professional
Calling a professional might be necessary if simple troubleshooting doesn’t resolve the furnace issue. Here are clear indicators that it’s time to seek expert help:
- Persistent Issues: If the furnace repeatedly fails to heat after attempting the basic fixes, such as checking the thermostat or clearing snow around the vents, professional assistance is recommended.
- Unusual Noises: If strange sounds, like banging or rattling, occur when the furnace operates, this could indicate a serious problem. Experts can diagnose and repair mechanical issues properly.
- High Energy Bills: If you notice a sudden spike in your energy bills without a corresponding increase in usage, your furnace may be malfunctioning. A technician can check for inefficiencies or faults in the system.
- Foul Odors: If you smell gas or any burning odor, shut off the furnace immediately and leave the area. Contact a professional to assess the situation, as this could pose a severe safety risk.
- Fluctuating Temperatures: If the temperature varies significantly from room to room or fails to meet your set temperature, the furnace might require professional calibration or repairs.
- Age of the Furnace: If your furnace is over 15 years old and starting to malfunction, contacting a professional can help assess its viability and repair needs.
Always prioritize safety. Professional HVAC technicians have the tools and knowledge to handle complex issues safely and effectively.
Preventative Measures For Future Storms
Taking proactive steps can prevent furnace issues during heavy snowstorms. Here are some key measures to ensure your furnace operates smoothly when you need it most.
Regular Maintenance
Schedule annual furnace maintenance with a certified technician. They’ll inspect components, test system efficiency, and make necessary repairs. Regular check-ups can extend the lifespan of your furnace.
Clear Surrounding Areas
Keep the area around your furnace clear of snow and debris. Shovel snow away from the exhaust vent and intake openings. Regularly check for clogs to ensure no blockage restricts airflow.
Insulate Pipes
Insulate exposed pipes to prevent freezing. Using foam pipe insulation keeps the pipes warm and reduces the risk of bursts, which can lead to costly repairs.
Test Your Thermostat
Test your thermostat before major storms hit. Adjust it to ensure proper functionality. Replace batteries as needed to avoid interruptions during snowstorms.
Install a Backup Power Source
Consider a generator for backup power. A generator provides electricity in case of an outage, ensuring your furnace continues to function. Make sure you follow safety guidelines when using a generator.
Monitor Indoor Air Quality
Keep an eye on indoor air quality. Use air purifiers and change filters regularly to maintain clean air circulation. Poor air quality can lead to respiratory issues when heating systems are operating.
Educate Family Members
Ensure everyone in your household knows how to operate the furnace and check basic settings. Instruct them on emergency procedures and when to call for help, promoting safety during outages.
Implementing these measures enhances your furnace’s reliability and keeps your home warm through winter storms.
Conclusion
Dealing with a furnace that won’t work after a snowstorm can be frustrating but knowing what to check can make a big difference. Remember to prioritize safety by turning off the furnace before troubleshooting. Simple steps like checking the thermostat and clearing snow from vents can often resolve the issue.
If you find yourself stuck despite your best efforts don’t hesitate to call a professional. They can help diagnose and fix any underlying problems. By staying proactive with maintenance and being prepared for winter storms you can keep your home cozy and warm all season long.
