Furnace: When to Call a Professional

A well-functioning furnace is essential for maintaining a comfortable home, especially during the colder months. While regular maintenance can help prevent issues, there are times when professional intervention is necessary. Here are key signs that indicate it's time to call a furnace technician:


1. Strange Noises

Unusual sounds such as banging, rattling, squealing, or grinding can signal mechanical issues, loose components, or airflow problems. A professional can diagnose and fix the problem before it worsens.


2. Inconsistent Heating

If some rooms in your home are significantly warmer or cooler than others, it could indicate ductwork issues, thermostat malfunctions, or a failing furnace. A technician can identify and resolve the underlying cause.


3. Short Cycling

When a furnace turns on and off frequently without reaching the desired temperature, it may be overheating due to a clogged filter, malfunctioning thermostat, or a more serious internal issue. A professional assessment is necessary to prevent further damage.


4. Rising Energy Bills

A sudden spike in energy costs without an increase in usage may indicate that your furnace is running inefficiently. Professionals can perform an inspection to improve efficiency and reduce costs.


5. Weak or No Airflow

If little to no air is coming from the vents, there may be an issue with the blower motor, fan, or clogged ducts. A technician can determine the cause and restore proper airflow.


6. Furnace Won't Start or Stay On

If your furnace fails to start or shuts off unexpectedly, the problem could be with the ignition system, pilot light, or electrical components. A professional can safely repair these issues.


7. Carbon Monoxide Alarm Activation

A carbon monoxide (CO) detector going off is a serious emergency. If this happens, turn off the furnace, ventilate your home, and call a professional immediately to inspect for leaks.


8. Yellow or Flickering Pilot Light

A pilot light should burn blue. A yellow, flickering, or irregular flame may indicate a gas imbalance or carbon monoxide risk, requiring immediate professional attention.


9. Persistent Burning Smells

A burning smell that doesn’t dissipate may indicate an electrical issue, overheating, or a dust buildup. A professional can check for fire hazards and prevent potential safety risks.


10. Age of the Furnace

If your furnace is over 15-20 years old and frequently experiencing issues, it may be time for a professional to assess whether repair or replacement is the best option.


Final Thoughts

While some minor furnace issues can be addressed with simple maintenance, persistent or unusual problems require professional expertise. Regular servicing can help extend the lifespan of your furnace, improve efficiency, and ensure safety. If you notice any of these warning signs, don't hesitate to call a qualified HVAC technician.

I definitely recommend TwinTech!

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!!
