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.

Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.

When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!

Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!

I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!
