Common Furnace Problems in Indian Hill, OH: Signs and Solutions
When the chill of winter arrives in Indian Hill, OH, the last thing you want is a furnace that’s not working as it should. Your furnace should keep your family warm and comfortable during the cold months, but it can sometimes run into trouble.
If you find yourself in this position over the winter months, don’t panic—understanding common furnace problems and their solutions can save you time, money, and a lot of frustration. Adams Heating & Cooling explains the most frequent furnace issues homeowners in Indian Hill encounter, how to troubleshoot them yourself, and when it’s time to call in our pros for furnace repair service.
1. Pilot Light Problems
The pilot light is a small flame that ignites the burners in older natural gas furnaces. If this flame goes out, your furnace won’t produce heated air.
Troubleshooting Tips
Relighting the pilot light in your furnace is a straightforward process, but it must be done carefully for your safety. Follow these steps:
- Turn Off the Furnace: Locate the furnace’s power switch and turn it off. This is often near the furnace.
- Turn Off the Gas: Turn the gas valve to the “Off” position and wait 5-10 minutes. This ensures that any remaining gas in the area dissipates to prevent accidental ignition.
- Find the Pilot Light Assembly: Open the furnace access door and locate the assembly, which is a gas valve with “On,” “Off,” and “Pilot” settings, and a small tube leading to the pilot light opening.
- Switch to Pilot: Turn the gas valve to the “Pilot” position. This setting allows gas to flow to the pilot light without activating the burners.
- Press and Hold the Reset Button: Locate the reset button near the gas valve. While holding the reset button, use a long lighter or match to ignite the pilot light. Continue to hold the button for about 30-60 seconds after the pilot light is lit to ensure the flame stays steady.
- Release the Reset Button: Slowly release the reset button. The pilot light should stay lit. If it doesn’t, repeat the process once more. If it still doesn’t stay lit, you may have a faulty thermocouple or other issue requiring professional repair.
- Turn On the Gas: Once the pilot light is burning steadily, turn the gas valve to the “On” position.
- Restore Power to the Furnace: Turn the furnace’s power switch back on and adjust the thermostat to your desired temperature.
When to Call a Professional
If the pilot light keeps going out or you notice a gas smell, turn off the furnace immediately and call Adams Heating & Cooling for heating repairs. Persistent issues could indicate a faulty thermocouple or gas valve
2. Blower Motor Problems
The blower motor will circulate air throughout your home once heated in the furnace. When it’s not working correctly, your furnace can’t heat effectively. You may notice weak or no airflow from the vents, or strange buzzing or humming noises coming from the furnace.
Troubleshooting Tips
- Check the Filter: A dirty air filter can restrict airflow and overwork the blower motor. Replace the filter if it’s dirty.
- Inspect the Vents: Make sure vents are open and unblocked by furniture or curtains.
- Reset the Motor: Some blower motors have a reset button near the unit. Press it and see if the problem resolves.
When to Call a Professional
If the motor continues to struggle or makes unusual noises, it may need repair or replacement. Unusual noises like buzzing, squealing, or grinding suggest mechanical issues such as misaligned fan blades or worn bearings that require expert repair. If the blower motor won’t start or runs continuously, it could stem from a faulty relay, capacitor, or control board, which needs professional tools and expertise to diagnose and fix safely.
3. Thermostat Malfunctions
Your thermostat is the command center of your heating system. If it’s not working properly, your furnace may not respond as it should. You may notice the furnace won’t turn on or it shuts off prematurely, or inaccurate temperature readings on the thermostat.
Troubleshooting Tips
- Replace the Batteries: Low batteries can cause communication issues between the thermostat and furnace. Replace the batteries and test that the system is working properly.
- Check the Settings: Make sure the thermostat is set to “heat” and the temperature is higher than the current room temperature. Also, set the fan to “auto”; using the “on” setting causes the furnace to blow cold air when it’s not actively heating.
- Clean the Unit: Dust and dirt can interfere with the thermostat’s sensors. Use a soft cloth or brush to clean it.
When to Call a Professional
If the thermostat doesn’t respond after these steps, it might need recalibration or replacement. Smart thermostats can also be tricky to set up, so professional installation ensures they work correctly with your system.
4. Frequent Cycling
Short cycling occurs when your furnace turns on and off too frequently, preventing it from heating your home effectively. The furnace turns off before reaching the set temperature and your energy bills climb higher despite reduced comfort.
Troubleshooting Tips
- Replace the Filter: A dirty filter can overheat the system, triggering safety shut-offs. Remove the old filter and replace it with a new one.
- Check Air Vents and Ducts: Ensure all vents are open and unobstructed by furniture, curtains, or debris. Inspect ductwork for visible blockages or damage that might restrict airflow.
- Inspect the Flame Sensor: The flame sensor detects if the burners are lit. A dirty or faulty flame sensor can cause the furnace to shut off prematurely. Clean the sensor with a soft cloth or lightly sand it with fine-grit sandpaper.
- Reset the Furnace: Turn off the furnace at the power switch or circuit breaker. Wait a few minutes, then turn it back on to see if this resolves the cycling issue.
When to Call a Professional
Persistent short cycling can be a symptom of many furnace issues, or indicate that your existing heating system is oversized. A furnace repair technician from Adams Heating & Cooling can assess the situation and recommend the best solution.
5. Water Leaks
High-efficiency furnaces that are condensing models use a secondary heat exchanger to capture more heat from exhaust gas, and can sometimes develop leaks. Leaks can lead to significant problems like water damage or system malfunctions if left unaddressed.
Troubleshooting Tips
- Inspect the Drain Line: Check the condensation drain line for clogs or blockages, which can cause water to back up. Clear the line with a small brush or a gentle stream of water.
- Test the Condensation Pump: For systems with a pump, verify that it’s functioning properly to move water away from the unit.
When to Call a Professional
If water continues to pool or the leak seems severe, it’s time to call a professional. Persistent leaks can indicate a faulty drain system, pump, or other internal issues that require expert inspection and furnace repair. Adams Heating & Cooling can identify the source of the problem and ensure your system runs smoothly and safely.
When DIY Furnace Repair Isn’t Enough
When DIY troubleshooting doesn’t resolve your furnace issues, it’s time to bring in a professional to ensure your system is repaired safely and effectively. Attempting to fix complex problems without the right tools or expertise can lead to further damage, void warranties, or even create safety hazards like gas leaks or electrical fires.
