Simple Troubleshooting For Your Furnace
Posted On: October 1, 2024
Here’s a straightforward guide for troubleshooting your furnace:
1. Check the Thermostat
Ensure your thermostat is set to “heat” and the temperature is higher than the current room temperature. If it's battery-operated, check the batteries as well.
2. Inspect the Furnace Switch
Locate the power switch, which often looks like a regular light switch near your furnace, and make sure it’s in the “on” position.
3. Check the Circuit Breaker
If the furnace isn’t turning on, check your home’s electrical panel for a tripped circuit breaker. Reset it if necessary.
4. Change the Air Filter
A clogged filter can restrict airflow, causing your furnace to overheat or not work efficiently. Replace it if it’s dirty or clogged.
5. Ensure Proper Airflow
Make sure that your air vents are open and not blocked by furniture or other items. Proper airflow is key to keeping your furnace running smoothly.
6. Inspect the Pilot Light or Ignition System
If your furnace uses a pilot light, ensure it’s lit. If you have an electronic ignition system, check the furnace manual for reset instructions.
7. Check for Gas Supply
Ensure the gas valve to the furnace is open. If you smell gas, turn off the furnace immediately and call a professional for assistance.
8. Examine the Furnace Flame
If the flame is yellow or flickering instead of blue, this could indicate a problem with combustion. Call a professional if this occurs.
9. Look for Error Codes
Many modern furnaces have a diagnostic system that will flash error codes if something’s wrong. Check the manual to decode any lights or beeps.
10. Call a Professional
If these steps don’t resolve the issue, it’s best to call a certified technician for a more thorough inspection and repair.
Regular maintenance, such as cleaning the furnace and replacing filters, can also prevent many of these issues from arising.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

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.

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.

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.

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.

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.

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

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!

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!!
