Furnace: When to Call a Professional
Posted On: February 24, 2025
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.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.
