Most Common Reasons For Your Furnace Breaking Down

Most Common Reasons For Your Furnace Breaking Down

A furnace breakdown is never convenient, especially during the cold months when you rely on it the most. Here are the most common reasons your furnace might stop working and how to prevent these issues:


1. Dirty or Clogged Filters

When filters are clogged, airflow is restricted, causing the furnace to work harder and overheat. This can lead to wear and tear on internal components.


Solution: Replace filters every 1 to 3 months during heavy use.


2. Thermostat Issues

A malfunctioning or incorrectly set thermostat can prevent the furnace from turning on or maintaining the desired temperature.


Solution: Ensure the thermostat is properly calibrated and the batteries are replaced regularly.


3. Ignition or Pilot Light Failure

Problems with the ignition system or a blown pilot light can prevent the furnace from producing heat.


Solution: Clean or replace the igniter and check for gas supply issues.


4. Lack of Maintenance

Skipping regular maintenance can lead to unnoticed problems, such as dirty burners or worn-out components, which cause the furnace to fail over time.


Solution: Schedule professional maintenance annually to keep your furnace running efficiently.


5. Mechanical Wear and Tear

Moving parts like belts, motors, and bearings can wear out over time, leading to inefficient performance or a complete breakdown.


Solution: Regular inspections can catch wear early, allowing for timely repairs.


6. Blocked or Leaking Ducts

Airflow issues caused by blockages or leaks in the ducts can force your furnace to work harder, eventually leading to a breakdown.


Solution: Inspect and seal ductwork as needed to maintain efficiency.


7. Overworking the System

Setting the thermostat too high or running the system continuously without breaks can overwork the furnace, leading to overheating or damage.


Solution: Use a programmable thermostat to optimize heating schedules and prevent overuse.


8. Electrical Problems

Blown fuses, tripped breakers, or faulty wiring can cause the furnace to stop working altogether.


Solution: Check your electrical panel and wiring connections or call a professional if needed.


9. Dirty Burners

If the burners are dirty, they can’t efficiently ignite and heat your home, leading to uneven heating or no heat at all.


Solution: Have a professional clean the burners during regular maintenance.


10. Aging Furnace

Furnaces typically last 15 to 20 years. As they age, efficiency decreases, and breakdowns become more common.


Solution: Consider replacing your furnace if repairs become frequent and the system is outdated.


Key Takeaway:
Regular maintenance, timely repairs, and proper usage can help extend the life of your furnace and prevent breakdowns. If you encounter issues, it’s best to consult an HVAC professional to diagnose and resolve the problem quickly.

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
