Common Furnace Problems

Dealing with furnace issues can be frustrating, especially when you’re relying on it to keep your home warm. Understanding common furnace problems can save you time, money, and stress. Let’s dive into some of the most frequent issues you might face with your Evcon furnace and how to troubleshoot them.

Furnace Not Turning On

If your furnace refuses to start, it might not be a major issue. Check the thermostat first—ensure it’s set to “heat” and the temperature is higher than the current room temperature. Dead batteries in the thermostat are often overlooked but can be a quick fix.

Next, check the circuit breaker. A tripped breaker will cut power to your furnace. Reset it, and see if that resolves the issue.

Still no luck? Inspect the furnace’s power switch. It’s easy to accidentally turn it off when cleaning or moving items around.

Insufficient Heating

Does your furnace turn on but fail to heat your home adequately? A dirty air filter could be the culprit. Clogged filters restrict airflow, making your furnace work harder and heat less effectively. Replace them every 1-3 months.

Another possibility is a malfunctioning thermostat. If it’s outdated or faulty, it might not communicate properly with your furnace. Consider upgrading to a programmable or smart thermostat for better efficiency.

If the problem persists, your furnace’s burners might need cleaning. Dust and grime can block the burners, reducing heat output. Turn off the power and gas supply before attempting any cleaning.

Blower Fan Issues

Noticed weak airflow or a blower fan that won’t stop running? Start by checking the fan setting on your thermostat. If it’s set to “on,” the fan will run continuously. Switch it to “auto” to let it cycle with the heating system.

Weak airflow might also be due to a dirty blower motor or fan blades. Dust can accumulate over time, reducing performance. Cleaning these components can often restore proper function.

If the fan doesn’t turn on at all, it could be an issue with the capacitor or motor. These parts may need professional repair or replacement.

Unusual Noises

A furnace making odd sounds can be unsettling. A banging noise might indicate expanding or contracting metal, which is normal, but it could also mean loose ductwork. Tighten any loose connections to fix this.

Whistling sounds often point to airflow restrictions. Double-check your air filters and ductwork for blockages. Replacing filters usually solves this problem.

A screeching noise might mean a worn-out blower motor belt. You can replace the belt yourself or call a technician if you’re unsure how to proceed.

Have you faced any of these furnace problems? Troubleshooting can feel overwhelming, but tackling one issue at a time often simplifies the process. Keep your tools handy and don’t hesitate to reach out to a professional if needed. Your comfort is worth it!
