What to Do When Your Furnace Unit Shuts Down

What to Do When Your Furnace Unit Shuts Down

If your furnace unexpectedly shuts down, it can be stressful, especially in cold weather. Before calling for professional help, here are a few steps you can take to troubleshoot the issue:


  1. Check the Thermostat
    Ensure the thermostat is set to "heat" and the temperature is set above the room temperature. Sometimes, the settings can get changed accidentally, causing the furnace not to kick on.


  2. Inspect the Power
    Verify that the furnace is receiving power. Check the circuit breaker and reset it if necessary. If the furnace is connected to a switch, ensure it’s turned on.


  3. Replace the Air Filter
    A clogged air filter can cause your furnace to overheat and shut down. If the filter is dirty, replace it and see if that solves the issue.


  4. Examine the Pilot Light or Ignition
    For older furnaces, check whether the pilot light is on. If it’s off, you may need to relight it. Newer models may have an electronic ignition, which should be inspected by a professional.


  5. Check the Furnace Door
    Some furnaces won’t operate if the access door is not properly closed. Double-check that the door is securely shut.


  6. Inspect the Vents
    Blocked vents can disrupt airflow, causing the furnace to shut down. Make sure all vents are open and unblocked.


  7. Examine the Flame Sensor
    A dirty flame sensor can cause the furnace to shut off after lighting. If you're comfortable, you can clean it with a soft cloth, but calling a professional might be the best option.


  8. Reset the Furnace
    Some furnaces have a reset button, typically located near the blower. Press it and wait a few minutes for the system to reboot.


  9. Call a Professional
    If none of these steps solve the issue, it’s time to call an HVAC technician. They can diagnose and fix any deeper issues with the system.


Regular furnace maintenance can prevent sudden shutdowns, ensuring your unit operates efficiently throughout the winter months.

by John from Toronto on Twintech Heating and Cooling

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

by Ryan k on Twintech Heating and Cooling

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.

The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

by Louise in Scarborough on Twintech Heating and Cooling

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

by Private User on Twintech Heating and Cooling

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

by Private User on Twintech Heating and Cooling

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

by Private User on Twintech Heating and Cooling

This is a professional team that's easy to deal with. I would strongly recommend them

by hj.taggart in OSHAWA on Twintech Heating and Cooling

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

by susieschoeppler in Oshawa on Twintech Heating and Cooling

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

by Private User on Twintech Heating and Cooling

Great service and great people to deal with, from sales to installer. I highly recommend this company.

by GR from Oshawa on Twintech Heating and Cooling

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!
