Common Symptoms of An Attic Furnace Not Working
When an attic furnace stops functioning properly, you may notice several symptoms that indicate a problem. Identifying these issues early can help prevent further complications.
Lack of Heat
You may experience insufficient or no heat distribution throughout your home. Common signs include cold spots in rooms and a significant temperature drop compared to the thermostat setting. If the furnace runs, but warm air doesn’t flow through the vents, check the following:
- Thermostat Settings: Ensure the thermostat’s setting is on “heat” and the temperature is set higher than the current room temperature.
- Clogged Filters: Replace or clean dirty filters, which can restrict airflow and reduce heating efficiency.
- Ductwork Issues: Inspect ducts for damage or blockages, which can impede heated air from reaching living spaces.
Unusual Noises
Unusual sounds from your attic furnace can signal trouble. Common noises include:
- Banging or Clanking: These sounds often indicate loose components or debris inside the furnace.
- Squealing: A squealing noise may suggest a worn or failing motor.
- Rumbling or Growling: This can point to a combustion issue, especially if the furnace is gas-powered.
If you hear any of these noises, it’s prudent to shut off the furnace and consult a technician. Not addressing these sounds can lead to more serious damage.
Possible Causes of Attic Furnace Malfunctions
Your attic furnace may encounter malfunctions due to several underlying issues. Identifying these causes can help you determine the next steps for repairs or maintenance.
Electrical Issues
Electrical problems often disrupt furnace operation. Circuit breakers may trip, cutting power to the unit. Check the breaker panel for any tripped breakers and reset them if necessary. Frayed wires or loose connections can also lead to malfunctions. Inspect the wiring, and consider hiring an electrician for repairs.
Thermostat Problems
Thermostat issues significantly affect furnace performance. Incorrect settings or a malfunctioning thermostat can prevent your furnace from receiving the proper signals. Ensure the thermostat is set to the desired temperature and functioning correctly. Replace batteries if applicable, and if problems persist, consider upgrading to a programmable thermostat for better control.
Mechanical Failures
Mechanical failures often result from wear and tear or lack of maintenance. Common issues include blower motor failure or a malfunctioning limit switch. Inspect the blower motor for signs of overheating or unusual noises, indicating potential failure. Regular cleaning and servicing can prevent these problems, so schedule maintenance yearly to address mechanical wear before it leads to malfunctions.
Troubleshooting Your Attic Furnace
Troubleshooting an attic furnace involves systematic checks and essential tools. Follow these steps to identify common issues and restore heat effectively.
Basic Checks to Perform
- Thermostat Settings: Verify that your thermostat is set to the desired temperature. Ensure it’s in heating mode and not set to ‘cool.’
- Power Supply: Check if your furnace has power. Inspect the circuit breaker and reset any tripped breakers.
- Filters: Examine air filters for clogs. Clean or replace them as necessary to ensure proper airflow.
- Vents and Ducts: Inspect supply and return vents for blockages. Remove any obstructions that could affect airflow.
- Pilot Light: For gas furnaces, confirm that the pilot light is lit. If it’s out, follow the manufacturer’s instructions to relight it safely.
- Screwdriver Set: Necessary for opening the furnace panel and accessing internal components.
- Multimeter: Useful for checking electrical connections and diagnosing power issues.
- Flashlight: Helps illuminate dark areas when inspecting the furnace or ducts.
- Wet/Dry Vacuum: Ideal for clearing debris from both the furnace and the ducts.
- Manifold Gauge Set: Required for evaluating gas pressure if your furnace operates on gas.
Utilizing these checks and tools can guide you towards effectively diagnosing and addressing issues with your attic furnace.
When to Call a Professional
Recognizing when to call a professional can save time and prevent further damage to your attic furnace. Some situations clearly indicate that expert help is necessary.

- Unusual Noises: Rumbling, banging, or squealing sounds can signal severe mechanical issues requiring immediate attention.
- Frequent Breakdowns: If repairs become regular occurrences, a professional evaluation can identify underlying issues that casual troubleshooting may overlook.
- Leaking Water: If you notice water pooling around the furnace, this indicates a potential malfunction that needs professional assessment.
- Electrical Problems: If you experience frequent tripped circuit breakers linked to your furnace, stop using it and call an electrician. This could point to dangerous wiring issues.
- Check Credentials: Ensure the technician is licensed and insured. This guarantees they meet local regulations and standards.
- Read Reviews: Look for customer feedback on platforms like Yelp or Google. Reliable technicians often have a track record of satisfied customers.
- Request Estimates: Get multiple quotes for the same service. This helps you gauge fair pricing and understand the scope of work proposed.
