Ignition Issues With Your Furnace
If your furnace isn’t turning on or staying lit, it may be experiencing ignition problems. Ignition issues can be frustrating, especially during colder months when you rely on your heating system to function properly. Understanding the possible causes can help you identify and solve the problem before calling in a professional. Here's a guide to common furnace ignition issues and potential solutions.
Pilot Light Issues: Older furnaces typically use a pilot light for ignition. If the pilot light is out, the furnace won’t ignite. This can be due to a draft, a dirty pilot light, or a malfunctioning thermocouple.
Solution: If the pilot light is out, try relighting it according to the manufacturer’s instructions. If it won’t stay lit, check for drafts or clean the pilot light assembly. You may also need to replace the thermocouple, which detects whether the pilot light is on.
Faulty Ignition Sensor: For newer furnaces with electronic ignition, the ignition sensor can sometimes malfunction. Over time, dirt and grime can accumulate on the sensor, causing it to fail in detecting the flame.
Solution: Cleaning the ignition sensor often resolves this issue. Turn off the furnace, remove the sensor, clean it with fine sandpaper or a brush, and reinstall it.
Ignitor Failure: Furnaces equipped with hot surface ignitors rely on a small electrical component to create heat for ignition. If the ignitor fails, the furnace won’t start.
Solution: Ignitors can wear out over time, and a replacement is usually necessary. This part is fragile, so it's best to have a professional technician handle the replacement.
Gas Supply Issues: If your furnace isn't getting enough gas, it won’t ignite. This could be due to a closed gas valve, low gas pressure, or an issue with the gas line.
Solution: Ensure that the gas valve is open and check your home's gas supply. If the issue persists, contact your gas company or a technician to inspect the gas lines.
Dirty Burners: Over time, the burners in your furnace can become clogged with dust and debris. Dirty burners can prevent proper ignition and cause the furnace to operate inefficiently.
Solution: Cleaning the burners can restore normal operation. This task is often best left to a professional, as improper cleaning can damage the components.
Blocked Air Intake or Exhaust: Modern furnaces have a safety feature that prevents ignition if the air intake or exhaust vent is blocked. This is a safety precaution to avoid dangerous gases from building up.
Solution: Check that the vents are clear of obstructions like leaves, snow, or debris. Clearing these blockages should allow the furnace to ignite properly.
While some furnace ignition issues can be resolved with basic troubleshooting, others require the expertise of an HVAC professional. If you're unsure or uncomfortable handling any components, it's best to contact a certified technician to ensure safety and proper repairs. Regular maintenance can also help prevent ignition problems, keeping your furnace running smoothly throughout the winter.
By addressing furnace ignition issues early, you can avoid more significant problems and ensure your home stays warm and comfortable.

Very professional, courteous, knowledgeable staff. Sales staff (David Gergley) excellent in knowledge and getting the job setup and installation was very prompt. Greg and Peter (technicians) knew their stuff and stuck around after completion to make sure it all worked properly and that I understood how it all was installed and how the unit worked. Would highly recommend them! Thanks for a great job-house is now cool and comfortable.
I had Twintech install a brand new air condition back in June of this year and I'm very happy with their service. I have a very busy schedule so I sent out an email to 7 or 8 HVAC companies just to get an idea of what it would cost. Dave at Twintech and only one other company were able to give me an approximate quote through email. Many of the companies I reached out to didn't even respond. I decided to meet with Dave and he was very friendly and professional. He gave me a good quote for a name brand/energy efficient AC with installation from their certified technicians. It was an easy decision to go with them.
Within a week I had the unit installed and working perfectly. Their technicians were very helpful and answered all of my questions. I'll definitely be calling them back for all of my HVAC needs in the future.
The people from Twintech were very friendly and personable...from the salesman to the installers. The installation was done as scheduled. I love my new air conditioner. My neighbour has a York and that thing is so noisy compared to my Goodman!! Thanks Twintech!!
Thank you, Twintech. They installed an A/C in my home in the middle of a heat wave which we appreciated very much. I found the team good, not overly friendly, other than the brothers. Dave, the salesperson was awesome, and, it's because of him that I was sold on using Twintech. I had other questions about additional work I am curious about and would have liked them to follow up and provide a quote. Other than that, which ultimately is not related to the great work they did, I would definitely recommend them, although I don't believe they go outside of Durham (check with them).
We have used this company a few times so I can't remember exactly what we paid but I do know that their fees are always very reasonable.
The first time we called Greg was when our furnace conked out while we were away. He came right away, showed me the problem and fixed it immediately.
The second time was when we needed an air conditioner moved and lifted to a platform. Again, he showed up on time, completed the job quickly (including a new gas line) and the fee was very reasonable.
We have received a quote from Greg to replace the air conditioner and furnace and when we are ready to move ahead, we will be calling him.
I have no hesitation in recommending TwinTech!
Our rating for Twintech is 5/5 stars. They are very professional and efficient, and the transparency they maintain right from the preliminary assessment till the day of the work is a testament to their experience in the field. We had Twintech replace our air conditioning and furnace, and we appreciate the efforts taken by Greg.
After 18 years my Air conditioner died in the middle of a heat wave. I entered my information on Home Stars and within the hour Dave from Twin Tech responded and offered to meet me as soon as possible depending on my availability. Dave was very knowledgeable about the products Twin Tech offered and even though this was the first quote I received . I felt very comfortable in giving Twin Tech my business. maybe it was the professional approach. Needless to say that the crew with Greg and Grant arrived promptly at the time they committed to were very professional and within a few hours had the place cool. They cleaned up and one would never know that I had work done . I know that the System is new and I probably wont need to worry about it for some time. However with the professionalism displayed by the crew I feel assured that should I need to call for service Twin Tech will respond. I also know that should I need a new Heating system I will go with Twin Tech. Keep up the good work.
Greg and team were amazing! All interaction via email and text 100% professional. From consult to product recommendation their service was phenomenal!
Installed a Napoleon furnace (ecm dc drive variable 2-stage) and it was a game changer for the whole house. Blended air temperature through and through the entire house and its saving us money by cutting down our utility bill by ALOT!
We purchased a new cooling & heating system from Twintech and the team was fantastic. From sales to installation, the team were great to work with. Friendly (our dog even enjoyed having them over), professional and accommodating. Id recommend Twintech in a heart beat to anyone. Superb customer service.
