Common Issues With Armstrong Forced Air Furnaces
Armstrong forced air furnaces may encounter several common issues that affect their performance and reliability. Understanding these problems helps you troubleshoot effectively.
Lack of Heat
If your furnace isn’t producing heat, check the thermostat settings first. Ensure the thermostat is set to “heat” and the temperature is higher than the current room temperature. Examine the air filter—if it’s clogged, replace it to restore airflow. Additionally, inspect the circuit breaker; a tripped breaker can halt operation. Look for error codes on the furnace’s display, which can provide specific guidance.
Unusual Noises
Strange noises from your furnace can indicate issues needing attention. Banging noises could mean loose components, while squealing often signals worn-out belts. Listen for rattling sounds, which might indicate debris in the blower motor. Investigate these noises promptly, as they may worsen if ignored. Regular maintenance can help prevent these problems.
Poor Airflow
If airflow feels weak, start by checking the air filter again; a dirty filter restricts airflow. Inspect the ductwork for obstructions or disconnects, as blockages reduce efficiency. Ensure that vents are open and unblocked by furniture or drapes. Adjusting the blower speed may also improve airflow, so check your furnace’s settings for optimal performance.
Step-by-Step Troubleshooting Guide
Troubleshooting your Armstrong forced air furnace can seem daunting, but following a logical process simplifies the task. Here’s a guide to help you address common issues effectively.
Checking the Thermostat
- Set Temperature: Ensure the thermostat is set higher than the current room temperature. A significant difference prompts the system to turn on.
- Batteries: If the thermostat is battery-operated, check and replace the batteries if necessary. Weak batteries can lead to inaccurate readings.
- Wiring: Inspect the wiring for any visible damage or loose connections. Tighten any loose wires to ensure proper communication with the furnace.
- Mode Setting: Confirm that the thermostat is in the heating mode. Sometimes it may inadvertently be set to “cool” or “off.”
Inspecting the Filter
- Location: Locate the air filter, typically found in the blower compartment or the return air vent.
- Visual Inspection: Check the filter for dirt, dust, and debris. A clogged filter restricts airflow and forces your furnace to work harder.
- Replacement: If dirty, replace the filter with a clean one. Use the same size as the old filter and ensure it fits snugly.
- Regular Maintenance: Schedule a filter check every one to three months to maintain optimal airflow and furnace efficiency.
- Power Supply: Check if the blower motor is receiving power. Ensure the power switch near the furnace is in the “on” position.
- Noise Levels: Listen for unusual sounds like grinding or rattling. These noises could indicate mechanical issues.
- Fan Operation: Observe the fan’s operation. If it doesn’t run when the system is on, the motor may require servicing or replacement.
- Lubrication: If accessible, try lubricating motor bearings according to the manufacturer’s recommendations to reduce friction and extend motor life.
By following these steps, you can troubleshoot many common issues with your Armstrong forced air furnace, ensuring it operates efficiently throughout the heating season.
When to Call a Professional
Recognizing when to call a professional for your Armstrong forced air furnace can prevent further issues and ensure safety. Here are situations that warrant expert assistance:
- Persistent Heating Problems: If your furnace continues to blow cold air despite DIY troubleshooting efforts, it’s time to seek a professional. A technician can assess complex issues that you might not be able to identify.
- Unusual Noises: If you hear banging, clanking, or other strange sounds, don’t ignore them. These noises often indicate mechanical failures that require expert evaluation.
- Frequent Cycling: If your furnace frequently turns on and off, a professional can diagnose problems with the thermostat or electrical systems that might not be fixable without specialized knowledge.
- Unusual Smells: If there are burning or gas smells, cease using the furnace immediately and call a technician. These can signal dangerous conditions that demand urgent attention.
- Older Systems: If your furnace is over 15 years old and you notice declining performance, consult a professional. Older systems may require repairs beyond simple fixes or even replacement.
- Increased Energy Bills: If heating costs spike unexpectedly, a professional can inspect for inefficiencies or safety hazards that an untrained eye might overlook.
Scheduling a professional inspection can offer peace of mind and ensure your heating system operates safely and efficiently.
Tips for Maintenance and Prevention
Maintaining your Armstrong forced air furnace ensures efficient operation and prolongs its lifespan. Follow these steps for effective maintenance and prevention:
Regularly Change Air Filters
Change air filters every 1 to 3 months. Clogged filters restrict airflow, causing the system to work harder and use more energy.
Schedule Annual Inspections
Schedule professional inspections annually. A technician can identify potential issues before they become severe, ensuring safe and efficient operation.
Clean Ducts and Vents
Clean air ducts and vents at least once a year. Dust and debris buildup can reduce airflow and efficiency.
Monitor Thermostat Settings
Check your thermostat settings regularly. Ensure it’s functioning correctly and set to the desired temperature.
Lubricate Moving Parts
Lubricate moving parts like the motor and blower bearings as needed. This reduces friction and helps prevent wear.
Check for Unusual Noises
Listen for unusual noises during operation. Strange sounds may indicate mechanical issues that require immediate attention.
Ensure Proper Drainage
Inspect the condensate drain for blockages. A clogged drain can cause water damage and lead to costly repairs.
Test Carbon Monoxide Detectors
Test carbon monoxide detectors monthly. This ensures your home remains safe from potential gas leaks.
Keep Surrounding Areas Clear
Keep at least 2 feet of clearance around your furnace. This improves airflow and reduces fire hazards.
Monitor Energy Bills
Track your energy bills for any sudden increases. A spike may indicate an inefficient furnace that needs servicing.
By implementing these tips, you maximize your furnace’s efficiency and maintain reliable home heating throughout the colder months.
Conclusion
Taking care of your Armstrong forced air furnace doesn’t have to be a daunting task. With a little troubleshooting and regular maintenance, you can keep your home warm and cozy all winter long. Remember to check those thermostat settings and change your air filters regularly to maintain efficiency.
If you encounter persistent issues or hear strange noises, don’t hesitate to call in a professional. Their expertise can save you time and ensure your system runs safely. By staying proactive and attentive to your furnace’s needs, you’ll enjoy a reliable heating experience season after season.
